First you would need to know how quickly the poles move, then you would need to calculate the differencial of the flux in one random spot on the surface of the earth, i think i have a formula somewhere in my notes. Then you would need to find the time it takes for it to change 0.0002-3 mT wich seems to be the precision of the instrument considering the noise. Oof too much free time needed Edit: B(r)= (,u0/4pi) { [3r*(m*r)/r^5] - [m/r³] } m is magnetic momentum, investigating further... Nvm i can't find m of the earth anywhere and I'm not sure it will work becouse it implies that the radius r is much larger than the lenght l of the dipole, and in our case it's just half of it.
I think we need to understand magnetism better in relation to the ether (See www.orgonelab.org/miller.htm) before we invest a lot of effort into such monitoring. You also might be interested in this research from this brilliant OSU professor: ua-cam.com/video/_A7VFVwAA5U/v-deo.html

WoAH, this satisfied all of my precision measuring itches, and when you did the earth's core demo it gave me a new sense of scale of our world.... now thats a big magnet in our planet.
The radius of Pluto is 1187 km, and the radius of the moon is 1738 km. "The Earth's field originates in its core. This is a region of iron alloys extending to about 3400 km (the radius of the Earth is 6370 km). It is divided into a solid inner core, with a radius of 1220 km, and a liquid outer core." TLDR: It's a pretty big magnet.
We will harness geo magnetics of the earth Tesla was already on to this... When we overcome the oil industry, we will have free energy ua-cam.com/video/WxhA9_PcR_o/v-deo.html
Most android smartphones also have a xyz magnetic/hall effect sensor. Type *#0*# into the telephone, click sensors and scroll to magnetic sensor. But of course, not as accurate as this meter.
@Matlaw the Geek Cool Sony code, but only works on Android. Sailfish X actually just tries to dial it (and the cell network gives an incorrect number error back), LOL.
I had myself observed this inclination of the Earth's field, and I often demonstrate it to friends and to random children using my collection of neodymium magnets. I find it easy to show with fair precision using 1.4"x1/4" cylinder magnets. I place 6 of them end to end, and capture a human hair between the two middle magnets. Suspend that from a doorway with a bit of tape, and the composite "bar" magnet will always find an orientation to magnetic north, including the vertical tilt.
You wanna tell me that flat-earthers actually use a single-plane compass to prove their hypothesis? While I wouldn't be surprised to hear "yes, really", it doesn't prove anything on the planet's shape - and neither does this video. It just gives a clue, and even if one would took such measurements all around the the world on different latitudes, it still could be "explained" in various fantastic ways. That's what actual science is for - to cut down the number of such explanations by making various tests and calculations. In the end of such process we should stay with only one answer holding true to all of such experiments.
@@BluesyBor And to do your best disproving your theory after providing evidence for it. Amazing number of one hit science examples that can't be repeated. The IPCC didn't even include the neighborhood Star as a variable. They really believe that a body can eschew billions of tons of matter each day for eternity without some variability? Freakin robots.

@@bryanst.martin7134 as for the disproving your own theory - I think it's better to leave it to others, since by doing it yourself you're kind of undermining your own credibility.

It's like jerking the pipe you just screwed into place, you can do it but it's always better to ask someone else to check if it's really solid, such person usually won't have any restraints you might have.
This is why the south end of a compass needle is counterbalanced, heavier than the north side of the needle so that the north end of the needle is not pulled downwards too much, preventing the compass from being able to move freely. The opposite is needed for a compass to work in the Southern Hemisphere. Just a day or two ago I was responding to a flat earther who said that compasses prove the Earth is flat. He knew about the near vertical magnetic field and I did not so I educated myself on how and why compasses work on a globe. That is when I learned about the counterweighted compass needle. I have learned so much from arguing against flat earth conspiracy theorists. As frustrating as it can be, I have learned more about our planet, space, gravity, momentum, scale, astronomy, reasoning, logic and more in just one year of debating them than I ever learned in my 40 years preceding. Finally I realise that flat Earthers are good for something! Your video on Earth's magnetic field being uploaded today is a nice little synchronicity too!
@@sebastian19745 Wise maneuver to run after dropping information on Flerfers I have to say. You are wise doing that. They drive me crazy! Happy New Year to you too. All the best to you.
I figured he was at a high latitude. A compass can be well or badly made. In the 19th century in the US, a watchmaker named Tate went into the compass business, but his product earned a reputation of low quality, hence the proverb: He who has a Tate’s is lost.
I think there was a few of us with Morty in our heads testing "absolute level" during your video. Great stuff who doesn't love magnets, I truly enjoyed my first Brainiac vid, looking forward to more.
Although it makes perfect sense, I never really thought about this. I always thought of it as the classic image of the flux lines coming out of the poles. Thanks for an interesting start to the week. Thanks also for a year of enlightening and entertaining videos. I'm keen to see what else you will show us with your new toy.
Congratulations. You just discovered how pigeons and other birds navigate. The Sun gives longitude while the vertical magnetic field gives latitude. Inside their brains are round structures containing molecular sized magnetized iron particles that due to gravity sit at the bottom of these cavities. Just like the demo you used at the end where the compass points vertical at the equator and horizontal at the north pole, these iron particles shift position inside the cavity and their polarized location is processed by their brains to give them latitude.

There are rod-shaped bacteria which build a little chain of magnets inside themselves. The magnets give them mostly a up-down orientation, so they can efficiently find the sweet-spot oxygen concentration in the sediment/mud they live in. That's useful for them because they are can only survive over a pretty narrow range of oxygen concentrations (too little means no respiration, but too much is toxic). Anyways, yeah... Unless you're at near the equator, the Earth's magnetic field is mostly up-down. PS: Nice way to do an advertisement. I want one of those teslameters now ;)

That’s an awesome piece of equipment. 35 Teslas!!! A new record of 45.5 T was just created with a superconducting magnet just last week. Though, measuring is easier than creating a strong magnetic field, but being able to measure micro Teslas with precision with the same probe is impressive.

From my understanding, all Magnets pull towards a huge Iron deposit under or near Hudson lake. This is why there is a declination constant when converting Magnetic north vs Grid North/True north. This is from what is was being taught to us in the Military and traveling the world. For example, in Germany the declination constant was somewhere over 20 degrees west but in most of the US you would have anything from a 3 to 7 degrees east. I am no scientist but I know what the maps said in different parts of the world and having to convert magnetic to true or magnetic to grid, these are the values we would have to use, found in the Maps Legend.
@@shines9290 there is a difference between true north, grid north and magnetic north and in most cases all three North's point in a different direction. But yes all magnets/magnetic compasses point towards the same local unless acted upon by other or outside interference
@@johnridderhof4505 When using a regular old compass it is not pointing towards the north pole but instead to Hudson lake? I really want to understand this. I will look into the three north's as well. Any information you can give me is much appreciated .
@@shines9290 sara, from my training in the military and my deployments around the globe, the short answer is yes. The declination constant on the east coast of the US has a small value west and the majority of the US has a declination constant of east. So Hudson lake may or may not be the exact location but it's used as the land mark for the average orientee. When hiking with a compass and a map the declination constant is a MUST. Otherwise your grid on your map will roatate without you knowing while the land marks will remain in grid position. And any distance and angle you set for your compass the further you go the further you will be off your target. Even though the north arrow on your map orients everything north. But not magnetic north
Oh, those are the two magnets you permanently stuck together.😄 So I am genetically predisposed to live with a 65° to 70° magnetic pull on my body. Yet I was born and have lived in a place where the pull is more along the 45° angle. I will have strange ponderings over this now. Because living outside of my natural magnetic pull angle has made me a strange person.😉😄
@@jetison333 It was a joke my friend. A hyperbolic play upon my heritage. Which is North European. Germanic, Dutch, and Scandinavian. You're right, I am silly by default.😉
seeker jay The experiment was done on earth. You know, reality. However, the compass would point straight down at the North Pole on a flat earth model. The opposite end would point to the star Polaris
Interestingly, we here in the southern hemisphere cannot use a compass designed to be used in the northern hemisphere and vice versa. They are balanced to suit the hemisphere they are to be used in. If you do try to use one of the opposite hemisphere compasses (compii? ;) ) then the needle will hit the casing.
I have understood that magnetic north is actually in Northern Canada not the North pole which is true north and the magnetic north pole has been moving north and west of the north pole. The teslameter is such a cool device but you've misaligned the globe for magnetic north. I think you'd see better results on the globe if the globe had been adjusted for Magnetic north.
True, it's actually flipped all the way over more than once in the distant past and is reckoned to be approaching another north south flip soon. But "soon" meaning within hundreds of thousands of years, maybe.
Ray Kent Actually "soon" means tomorrow or within a few hundred thousand years. That’s because we are over due by 300,000 years plus from their calculations. Just as Yellowstone could go off "soon" they can’t predict when but the patterns suggest we are over due. Some also think it’s happening as we speak with abnormalities, and evidence of a third strong point heading north which could cause the flip. Speculating but there might be more then one magnet at the center of the earth with verifying strength, we don’t know what exactly is there after all.
Magentic north= Southpole Magentic south= Northpole (near Canada) Northpole of compass points to south, that's why it's called the Northole - makes sense, rigth?
You follow in the footsteps of the old vikings and your famous countryman Oersted... The vikings are assumed to have sailed in the open seas using an early magnetic compass. Oersted put the science into the magnet business. Great visualizations! Here is a little memory from my childhood. I had a book, called something like “Young Inventors’ and Experimenters’ Book” that described how some boys showed each other their experiments and built items. Among those experiments was how to magnetize steel rods or needles. Then to verify that indeed it had become magnetized, the bigger rods could be hung from their center point to a thin sewing thread and it would turn to roughly North/South. Careful about the twist of the thread, though. But the smaller needles could be covered with a thin layer of butter and settled carefully on top of a full water barrel, where the surface tension kept it floating and it turned freely to N/S orientation. Guess what - I got one of my mother’s sewing needles and repeated the test. That served to teach me about surface tension in addition to the magnetism. And I can be proud that I also did NOT lose the needle.
Was leveling a pool table with friends help. They didn't believe me when i stated that rolling a glass marble on a piece of flat glass would be far more accurate than a carpenters level. After i got the marble and glass out they wondered why i spent so long cleaning it and checking for one without scratches, they didn't believe when i said a tiny scratch or speck of dust can prevent the marble from rolling. I explained that the amount of contact area between a round object and flat one is tangential and that a speck of dust is pretty big compared to that. Later i explained that flat glass is a modern invention and that old glass was never as flat and its amazing we as a species could create such flatness on a surface so hard to work with. That made me curious how it was produced and i later researched it. They never did believe me and all 3 of em went home thinking i was dumb and spouting nonsense all day... Post ended up being a paragraph lol, im still annoyed by this.

That is also why marine compasses are gimballed and have large vertical freedom. No flat earthers around people who have seen someone sail off over the horizon when out of sight of land.

Cool experiment. Glad I stumbled across it. And good for you for giving the Teslameter to a good home. That's a grand gesture, even though I'm sure you don't have a ton of use for it. But giving to a real scientist instead of selling to the highest bidder is a really cool move.

What a brillant demonstration, not only about the inclination of the earth magnetic field, but also of how a scientific intuition can become a subject for testing a method, in search for more accuracy.
Hi, I have a few questions. Firstly, I am not advocating for Flat Earth, Helicentric, Geocentric, Concave Earth, Convex Earth, Inner Earth, Infinte Plane, etc etc. I was watching a video, Professor Eric Laithwaite: Magnetic River 1975, and it spiked my interest in magnets. So if my questions seem basic or nonsensical it is because I know very little about them. 1. How is _"a compassed balanced in a way that makes it useful for horizontal navigation"_ ? 2. How does a compass and a dip circle differ, in relation to operation? 3. When you set up the F71 probe, did you also put a compass next to it to compare them for both for North? 4. _"It is believed that the molten iron and nickel in the outer part of the Earth's core is generating the magnetic field"_ This raises many questions, but I will ask just one. Are able to demonstrate or explain how this works, especially in relation to the Curie Temperature? 5. Or maybe two questions - if the molten core is sworling and moving and being affect by the "Coriolis effect" of the earths motion, why does it not produce smaller, more localised magentic fields instead of just one large one? As is demonstrated by the weather. 6. Isnt using a large magnet in the half globe model just a confirmation bias? 7. Did you try the compass on the "southern" half of the globe model? 8. Do you know someone in the Southern hemisphere that can do the same test? Or do you know of a video similar to this one that is performed in the South? Thanks in advance.
1. Since the field points downwards at an angle if you're not on the equator, it will tend to pull one side of the needle down more than the other. The compass needle would tend to tilt if it's not balanced to counteract that unequal force. 2. Since compasses are balanced to keep them level when they are horizontal, the heavy side will pull that end of the needle straight down if held vertically because of gravity. A dip circle is evenly balanced, so it will point at the angle of the magnetic field. 3. No need to do them side by side, compasses and the F71 probe both work, thus they will give consistent results. 4. The center of the earth is solid, even though it's hot because of the immense pressure. I don't know for sure, but i would guess that the curie temperature varies based on the pressure as well as temperature. 5. The core of the earth is solid, thus no swirling. If it was not solid, then there would be no magnetic field. 6. No, it's a model to demonstrate the principle. 7. No need, the compass needle would start pulling the other side of the compass needle toward the magnet as you move toward the south pole. 8. You could go check the governments chart of the main field inclination to get data from points all over the world.
Adding to the variation is that the magnetic north pole is not the same as the true north pole. The magnetic north pole is in northeastern Canada somewhere, though, apparently, it has been slowly shifting closer to true north over the last century.
You can actually do the same test with your smartphone. The highest you can get when the phone is level pointing north is around 22-23 μT, pointing it north but angled downward however this goes up to 50μT!
I could only wish that physicians, historians could start every sentence with worlds: as our today's best knowledge... Im sick of all those theories who are 100%right today and they are scrapped in next 10 years.
There are no absolutes in science. A theory is saying "with all the knowledge we have right now, this is how we understand it". Theories are discarded when new theories arise which gives us a better understanding.
Remember spending days trying to learn how to figure out my direction on a map with different compasses until I learned this. You don't even need to be above the core to get misreadings too.
Did you figure out this yourself, wanted to re-produce it or was curious after some statement people had ... either way ... very well done ! Expect your video to pop up in many flat earth arguments :)
I'm still wondering how molten metal can be magnetic, as you know the higher the temp in most metals the less magnetic it gets. The reason they are magnetic at all is the orientation of the grain structure in them is locked in a certain position. So if the magnetic field were really generated by flowing magma or a spinning core it would be unbelievably unstable and varying if it functioned at all.
You are thinking of ferromagnetism. That's a permanent magnet. That's not the only way magnetic fields are created. For instance, a strong current also generates a magnetic field (and vice versa).
@@Veiss7 You just need a current to provide a magnetic field. Currents actually increase when you have a decrease in impedance/resistance. Here's a little info from Wiki on it: en.wikipedia.org/wiki/Electromagnetism And one other smaller link: www.physics.org/article-questions.asp?id=64 Here's another link, this time to an experiment to replicate the effect in a small model: ua-cam.com/video/rAYW9n8i-C4/v-deo.html Just to give some other info. This effect is based on the fundamental principles of electromagnetism, and is well known.
@@Desrtfox71 that experiment shows no data just people talking next to a machine... in any case do you have some evidence to show magnetism in flowing magma? The article use math and theories but I haven't seen any data or evidence.
@@Veiss7 The Earth's core is not made up primarily of magma. The core is made up of iron primarily, and then nickel. I trust you don't need me to provide evidence of conductivity in such materials? Here's a breakdown of the composition of Earth: www.iupui.edu/~g115/mod04/pop02.html Nevertheless, here's a plot showing iron's conductivity by temperature: www.researchgate.net/figure/Thermal-conductivity-and-electrical-conductivity-versus-temperature-for-air-iron-vapour_fig5_258261081 Also, I'mg getting the impression that you're less concerned about understanding the science here, and more interested in simply arguing. I have better things to do than argue with someone who will not do the most basic research to educate themselves. Assuming I'm incorrect, here's a good link to find all the evidence based information you need on magnetism, electromagnetism, the Earth's composition, and the Earth's dynamo effect: scholar.google.com/
So why ain't we able to to levitate by making a platform of a magnet pointing same direction as the earth's pole ... To create a separation from the earth or resistance... Hummm i wonder.... May be there is not such a thing of magnetic field ... Or if it is so it may not work exactly as we thing ... So that being said this experiment or anything similar to this wont tell us much ...
Or simply put... there are two forces at play. One is magnetism and the other is gravity. They are not the same thing at all. If there was only magnetism, then non ferrous materials would be unaffected. Yes?
Magnetospheres exists on ALL large bodies....not all large bodies have iron/nickel cores....ergo it’s not likely an Iron/Nickel core causing the magnetosphere.....
I think that ruling out the iron and nickle core in Earth as the source of the magnetic field is kinda a jump in logic. Just because other large bodies don't have a core of iron/nickle but do have magnetic fields doesn't mean that the one in Earth isn't the cause. All it does mean for certain is that iron/nickle cores aren't the only source of magnetospheres. It just sounds like you're trying to suggest some kinda of supernatural cause or something
@PST3K NaN we do know. While being unable to directly observe, you can take other measurements such as Earth's diameter and calculate it's mass. From those you can come up with a density for Earth. You compare the density to the surface materials and seismic data and you can get a picture of how the layers are set out; with lighter materials "floating" on denser ones. From that we can calculate the mass and size of the core and from that we can min what materials it is made of. Something heavy and common; iron and nickle. So while yes, we've never seen it in person, we don't need to.
Is that a smear-sphere campaign slogan? I've only heard it about a thousand and one times. Rhetoric is strong in you Padowan. Repetition is key to belief. See it, say it, repeat it.
I took the arctan(x/z) for the values shown at 6:17 and I got 69.31 degrees of tilt. This is assuming the probe was perfectly level to begin with but it fits with the other measurements of about 70 degrees.
You can also do this with the raw values from the magnet sensor in your smartphone. arctan(Z/Y) and you get the inclination if the phone faces north (X=0).
He did use 2 flat magnets inside the heliocentric globe model. And still not representative of what heliocentric globe model would be, accurately speaking the core shape would be same as heliocentric globe model.
i dont understand this, earth is round, north pole is north, so unless u are within (~100km?) of true north it wont point down? whats the point? if u stand right in the center of the south pole it would point straight down and a level compass would spin? please explain whats the point of this video
It's fascinating that because the real 'north pole' is located so incredibly far beneath the 'north pole' anywhere outside the tropics the magnetic field is largely aligned downward. It's also showing off some cool equipment that can make such amazing precise measurements.
Awesome video man. Im writing a book currently that uses this is a world power source. its "fiction" because im not an actual scientist. BUt i think i figured it out.. (so far only works on a small scale.)
actually im talking about an ionic generator. Lined up properly , taking in account the pull of the planet and the magnetism points of the earth, i believe its possible. if lined up properly. but im also talking about a fictional part of a fictional book, so you know.. who really cares if it would actually work or not.
The reason the compass on the globe shows an angle of around 80 degrees while the ball and probe say 70 degrees is most likely because magnetic north is currently in Canada, so the hemisphere would need to be rotated slightly to align magnetic north with the magnet. My old professor studied geomagnetic anomalies, and had a magnetometer sensitive enough to detect a bus travelling 100m away. It used a coil with 120,000 turns.
Wow - great video. I was just talking to my pre-teen about magnetic polarization and its role in proving the theory of continental drift. This video will be a great way to help him understand!
F71 that's a 7000 USD device and hence Denmark tech-tax level and another +25% VAT on top' we are closer to 10.000 USD so not cheap too say the least. Solid donation from Lake Shore and imo one of the best magnetic channels on youtube..so very fitting and congrats with it Brainiac and thx Lakeshore for the channel donation thats a nice tool for the viewers to keep track of the magnetic force. but I would love if you could check such a lab grade Teslameter-device vs. everyday Teslameter sensors, like fx in Ipad etc. that also have these Gauss and Tesla and axes-values {X,Y,X], just to sense how solid are these everyday sensors on of course only small magnets.imgur.com/a/DZdRRjq
I found this example interesting, absolutely. However, when removing the magnetism from our tools, we use heat, a torch. We remove magnetism with heat because heated iron can't be magnetic. Since we've known that for a few hundred years, I wasn't surprised when the "Electric Universe" guys found the cylindrical field, apparently created by the Pedersen current moving through the Earth crust. From what I understand, all of your findings from your measurements are accurate for the cylinder model. The only thing different today, from when I studied it in 1969, is that today we know it isn't a molten core causing the field, it's energy pumped into our crust by our star, which, unfortunately, is dimming and it's electron output has, 1) converted to proton emission, 2) is dimming even as we watch this video. While we enter a very powerful cold spell of, probably, 150-years, or more, at which time our star will have created enough atoms of Tritium and Deuterium (isotopes of hydrogen) to begin burning that, again, and our weather will, basically, return to what it was 70 years ago when I started looking at this issue. Apparently, astronomers call this the helium flash, and ice-cores, and tree-rings tell us this cycle happens about every 400-years and on one occasion, I saw it end (the ice) after 56-years and in the worst, it lasted 156-years. That was long ago and the ice was three miles deep over Michigan when that rock landed there making that strange crater. Several other times, ice-dams along the Canada U.S.A. border, caused floods of water (ice-melt) miles deep to rush over the American bad-lands area, 60MPH, creating vortices that scoured out those impressive standing tower formations while the water raced toward Oregon and the ocean. Actually, our evidence indicates it happened, at least, four times. Don't worry, it's cyclical and will be normal again one day...and then it will happen again, and again.
Instead of the flat plate for the spherical magnet you could use an oiled parabolic surface. Set the magnetic sphere on the slope and release. After oscillating in ever decreasing arcs in the dish it should align with the earth's magnetic field at the bottom.
... this was in recommended for some reason and i click on it. "HI!!!!! Have you ever wondered about the direction of the earths magnetic field????????"
Acording to measurements the angle is: angle = atan(0.0464/-0.0181) = -1.19865 radians or -68.68992º. the negative means that the north pole of the instrument is aligned to the north pole of the field
Color television picture tubes (cathode ray tubes, CRTs) were designed for either northern or southern hemisphere use to minimize the possibility of color impurities in the picture. However, a CRT designed for one hemisphere could be used optimally in the opposite hemisphere by mounting it upside down. Some sets sold in the southern hemisphere were manufactured this way.
I knew the fields run round the earth top to bottom. This was a great way to demonstrate it. Great job. Maybe add something about the difference between true north and geographic north.
if you dig a little deeper you also find that map north and magnetic north are in different locations. what we consider to be the north pole is the center axis of earth where as magnetic north is where the magnetic field converges.
When I was a little kid I asked my dad, Paul Pantone, the inventor of GEET, how to make magnets. He taught me how to attach an antenna to the north terminal of a battery at this relative angle to charge the battery. Have you heard of that? Tried it?
I'd love to see a time-lapse showing how it changes over time. Something like that might need to span decades though...
First you would need to know how quickly the poles move, then you would need to calculate the differencial of the flux in one random spot on the surface of the earth, i think i have a formula somewhere in my notes.
Then you would need to find the time it takes for it to change 0.0002-3 mT wich seems to be the precision of the instrument considering the noise.
Oof too much free time needed
Edit:
B(r)= (,u0/4pi) { [3r*(m*r)/r^5] - [m/r³] }
m is magnetic momentum, investigating further...
Nvm i can't find m of the earth anywhere and
I'm not sure it will work becouse it implies that the radius r is much larger than the lenght l of the dipole, and in our case it's just half of it.
I was thinking that the only other person I could think of that could put one of these to good use would have been Cody, and boom there you are!

WoAH, this satisfied all of my precision measuring itches, and when you did the earth's core demo it gave me a new sense of scale of our world.... now thats a big magnet in our planet.
The radius of Pluto is 1187 km, and the radius of the moon is 1738 km.
"The Earth's field originates in its core. This is a region of iron alloys extending to about 3400 km (the radius of the Earth is 6370 km). It is divided into a solid inner core, with a radius of 1220 km, and a liquid outer core."
TLDR: It's a pretty big magnet.

I had myself observed this inclination of the Earth's field, and I often demonstrate it to friends and to random children using my collection of neodymium magnets.
I find it easy to show with fair precision using 1.4"x1/4" cylinder magnets. I place 6 of them end to end, and capture a human hair between the two middle magnets. Suspend that from a doorway with a bit of tape, and the composite "bar" magnet will always find an orientation to magnetic north, including the vertical tilt.
Nice.
So the magnetic field isnt.... flat!!
So... if you believed it was flat before, you were a flat earther :P
Im a terraplanist, and i love this channel, that's because this is true sience. (sorry, my english sucks u_u)
You wanna tell me that flat-earthers actually use a single-plane compass to prove their hypothesis? While I wouldn't be surprised to hear "yes, really", it doesn't prove anything on the planet's shape - and neither does this video. It just gives a clue, and even if one would took such measurements all around the the world on different latitudes, it still could be "explained" in various fantastic ways.
That's what actual science is for - to cut down the number of such explanations by making various tests and calculations. In the end of such process we should stay with only one answer holding true to all of such experiments.
@@BluesyBor And to do your best disproving your theory after providing evidence for it. Amazing number of one hit science examples that can't be repeated.

This is why the south end of a compass needle is counterbalanced, heavier than the north side of the needle so that the north end of the needle is not pulled downwards too much, preventing the compass from being able to move freely. The opposite is needed for a compass to work in the Southern Hemisphere. Just a day or two ago I was responding to a flat earther who said that compasses prove the Earth is flat. He knew about the near vertical magnetic field and I did not so I educated myself on how and why compasses work on a globe. That is when I learned about the counterweighted compass needle. I have learned so much from arguing against flat earth conspiracy theorists. As frustrating as it can be, I have learned more about our planet, space, gravity, momentum, scale, astronomy, reasoning, logic and more in just one year of debating them than I ever learned in my 40 years preceding. Finally I realise that flat Earthers are good for something!

I figured he was at a high latitude.
A compass can be well or badly made. In the 19th century in the US, a watchmaker named Tate went into the compass business, but his product earned a reputation of low quality, hence the proverb:
He who has a Tate’s is lost.
I think there was a few of us with Morty in our heads testing "absolute level" during your video. Great stuff who doesn't love magnets, I truly enjoyed my first Brainiac vid, looking forward to more.

Thanks also for a year of enlightening and entertaining videos. I'm keen to see what else you will show us with your new toy.
another fact. northern and southern hemisphere have compasses that are calibrated differently. so the needle is balanced properly
Congratulations. You just discovered how pigeons and other birds navigate. The Sun gives longitude while the vertical magnetic field gives latitude. Inside their brains are round structures containing molecular sized magnetized iron particles that due to gravity sit at the bottom of these cavities. Just like the demo you used at the end where the compass points vertical at the equator and horizontal at the north pole, these iron particles shift position inside the cavity and their polarized location is processed by their brains to give them latitude.
So awesome to see a Danish science channel of this quality. As a future physics teacher I will without a doubt use your videos!

There are rod-shaped bacteria which build a little chain of magnets inside themselves. The magnets give them mostly a up-down orientation, so they can efficiently find the sweet-spot oxygen concentration in the sediment/mud they live in. That's useful for them because they are can only survive over a pretty narrow range of oxygen concentrations (too little means no respiration, but too much is toxic).
Anyways, yeah... Unless you're at near the equator, the Earth's magnetic field is mostly up-down.

From my understanding, all Magnets pull towards a huge Iron deposit under or near Hudson lake. This is why there is a declination constant when converting Magnetic north vs Grid North/True north. This is from what is was being taught to us in the Military and traveling the world. For example, in Germany the declination constant was somewhere over 20 degrees west but in most of the US you would have anything from a 3 to 7 degrees east. I am no scientist but I know what the maps said in different parts of the world and having to convert magnetic to true or magnetic to grid, these are the values we would have to use, found in the Maps Legend.
interesting
Are you saying north for all magnets across the entire world is pointing toward Hudson lake only?
@@shines9290 there is a difference between true north, grid north and magnetic north and in most cases all three North's point in a different direction. But yes all magnets/magnetic compasses point towards the same local unless acted upon by other or outside interference
@@johnridderhof4505 When using a regular old compass it is not pointing towards the north pole but instead to Hudson lake? I really want to understand this. I will look into the three north's as well. Any information you can give me is much appreciated
.
@@shines9290 sara, from my training in the military and my deployments around the globe, the short answer is yes. The declination constant on the east coast of the US has a small value west and the majority of the US has a declination constant of east. So Hudson lake may or may not be the exact location but it's used as the land mark for the average orientee. When hiking with a compass and a map the declination constant is a MUST. Otherwise your grid on your map will roatate without you knowing while the land marks will remain in grid position. And any distance and angle you set for your compass the further you go the further you will be off your target. Even though the north arrow on your map orients everything north. But not magnetic north
Oh, those are the two magnets you permanently stuck together.😄
So I am genetically predisposed to live with a 65° to 70° magnetic pull on my body. Yet I was born and have lived in a place where the pull is more along the 45° angle. I will have strange ponderings over this now. Because living outside of my natural magnetic pull angle has made me a strange person.😉😄

funny

Yes!
seeker jay The experiment was done on earth. You know, reality. However, the compass would point straight down at the North Pole on a flat earth model. The opposite end would point to the star Polaris
Flat earthers use tape for pasting the stars to their fictitious dome.
Interestingly, we here in the southern hemisphere cannot use a compass designed to be used in the northern hemisphere and vice versa. They are balanced to suit the hemisphere they are to be used in. If you do try to use one of the opposite hemisphere compasses (compii? ;) ) then the needle will hit the casing.
that is cool! i hade one for them! now I know why :D
you said creampie comply
They do make global compasses that will work in both hemispheres.
I have understood that magnetic north is actually in Northern Canada not the North pole which is true north and the magnetic north pole has been moving north and west of the north pole. The teslameter is such a cool device but you've misaligned the globe for magnetic north. I think you'd see better results on the globe if the globe had been adjusted for Magnetic north.
It moves but it was about 4 degrees off the true north pole in 2015
True, it's actually flipped all the way over more than once in the distant past and is reckoned to be approaching another north south flip soon. But "soon" meaning within hundreds of thousands of years, maybe.
Ray Kent Actually "soon" means tomorrow or within a few hundred thousand years. That’s because we are over due by 300,000 years plus from their calculations. Just as Yellowstone could go off "soon" they can’t predict when but the patterns suggest we are over due. Some also think it’s happening as we speak with abnormalities, and evidence of a third strong point heading north which could cause the flip. Speculating but there might be more then one magnet at the center of the earth with verifying strength, we don’t know what exactly is there after all.
Magentic north= Southpole
Magentic south= Northpole (near Canada)
Northpole of compass points to south, that's why it's called the Northole - makes sense, rigth?
You follow in the footsteps of the old vikings and your famous countryman Oersted...
The vikings are assumed to have sailed in the open seas using an early magnetic compass. Oersted put the science into the magnet business.
Great visualizations!
Here is a little memory from my childhood. I had a book, called something like “Young Inventors’ and Experimenters’ Book” that described how some boys showed each other their experiments and built items. Among those experiments was how to magnetize steel rods or needles. Then to verify that indeed it had become magnetized, the bigger rods could be hung from their center point to a thin sewing thread and it would turn to roughly North/South. Careful about the twist of the thread, though. But the smaller needles could be covered with a thin layer of butter and settled carefully on top of a full water barrel, where the surface tension kept it floating and it turned freely to N/S orientation. Guess what - I got one of my mother’s sewing needles and repeated the test. That served to teach me about surface tension in addition to the magnetism. And I can be proud that I also did NOT lose the needle.
Was leveling a pool table with friends help.
They didn't believe me when i stated that rolling a glass marble on a piece of flat glass would be far more accurate than a carpenters level. After i got the marble and glass out they wondered why i spent so long cleaning it and checking for one without scratches, they didn't believe when i said a tiny scratch or speck of dust can prevent the marble from rolling. I explained that the amount of contact area between a round object and flat one is tangential and that a speck of dust is pretty big compared to that.
Later i explained that flat glass is a modern invention and that old glass was never as flat and its amazing we as a species could create such flatness on a surface so hard to work with. That made me curious how it was produced and i later researched it.
They never did believe me and all 3 of em went home thinking i was dumb and spouting nonsense all day...

What a brillant demonstration, not only about the inclination of the earth magnetic field, but also of how a scientific intuition can become a subject for testing a method, in search for more accuracy.
Hi, I have a few questions.
Firstly, I am not advocating for Flat Earth, Helicentric, Geocentric, Concave Earth, Convex Earth, Inner Earth, Infinte Plane, etc etc.
I was watching a video, Professor Eric Laithwaite: Magnetic River 1975, and it spiked my interest in magnets.
So if my questions seem basic or nonsensical it is because I know very little about them.
1. How is _"a compassed balanced in a way that makes it useful for horizontal navigation"_ ?
2. How does a compass and a dip circle differ, in relation to operation?
3. When you set up the F71 probe, did you also put a compass next to it to compare them for both for North?
4. _"It is believed that the molten iron and nickel in the outer part of the Earth's core is generating the magnetic field"_
This raises many questions, but I will ask just one.
Are able to demonstrate or explain how this works, especially in relation to the Curie Temperature?
5. Or maybe two questions - if the molten core is sworling and moving and being affect by the "Coriolis effect" of the earths motion, why does it not produce smaller, more localised magentic fields instead of just one large one? As is demonstrated by the weather.
6. Isnt using a large magnet in the half globe model just a confirmation bias?
7. Did you try the compass on the "southern" half of the globe model?
8. Do you know someone in the Southern hemisphere that can do the same test? Or do you know of a video similar to this one that is performed in the South?
Thanks in advance.
1. Since the field points downwards at an angle if you're not on the equator, it will tend to pull one side of the needle down more than the other. The compass needle would tend to tilt if it's not balanced to counteract that unequal force.
2. Since compasses are balanced to keep them level when they are horizontal, the heavy side will pull that end of the needle straight down if held vertically because of gravity. A dip circle is evenly balanced, so it will point at the angle of the magnetic field.
3. No need to do them side by side, compasses and the F71 probe both work, thus they will give consistent results.
4. The center of the earth is solid, even though it's hot because of the immense pressure. I don't know for sure, but i would guess that the curie temperature varies based on the pressure as well as temperature.
5. The core of the earth is solid, thus no swirling. If it was not solid, then there would be no magnetic field.
6. No, it's a model to demonstrate the principle.
7. No need, the compass needle would start pulling the other side of the compass needle toward the magnet as you move toward the south pole.
8. You could go check the governments chart of the main field inclination to get data from points all over the world.

@@dylanbiddle123 there is some liquid, molten metal around the core, but I think it's magnetically inert, or fairly close to it
I'd rather ask... if magnets lost their magnetism when heated, why - if molten - is there any magnetism in earth's core at all?
8:55 best line never used by Rik & Ade in any of the Bottom live shows! (wish they had though!)
They didn't talk about percussion, they just did it!
Actually, in many ways, THIS is your coolest video.
Adding to the variation is that the magnetic north pole is not the same as the true north pole. The magnetic north pole is in northeastern Canada somewhere, though, apparently, it has been slowly shifting closer to true north over the last century.
At 5:36, you could have taken 90-180/pi*sin(180/498) and gotten 69.74 degrees.
You could also just use arc tan on the ratio of X/Z. Just put this into Google: atan(0.0464/0.0186) in deg
"this is a mountable probe but I'm lazy and just eyeball it by hand"... I feel you bro ☝🏽
You can actually do the same test with your smartphone. The highest you can get when the phone is level pointing north is around 22-23 μT, pointing it north but angled downward however this goes up to 50μT!
I could only wish that physicians, historians could start every sentence with worlds: as our today's best knowledge... Im sick of all those theories who are 100%right today and they are scrapped in next 10 years.
There are no absolutes in science. A theory is saying "with all the knowledge we have right now, this is how we understand it". Theories are discarded when new theories arise which gives us a better understanding.
First Video for me- very interesting, thanks. (Now Subscribed, to catch-up!).
One of the best education UA-cam videos I have even had the pleasure of watching. Great work!
Remember spending days trying to learn how to figure out my direction on a map with different compasses until I learned this. You don't even need to be above the core to get misreadings too.
Did you figure out this yourself, wanted to re-produce it or was curious after some statement people had ... either way ... very well done ! Expect your video to pop up in many flat earth arguments :)
I'm still wondering how molten metal can be magnetic, as you know the higher the temp in most metals the less magnetic it gets. The reason they are magnetic at all is the orientation of the grain structure in them is locked in a certain position. So if the magnetic field were really generated by flowing magma or a spinning core it would be unbelievably unstable and varying if it functioned at all.
You are thinking of ferromagnetism. That's a permanent magnet. That's not the only way magnetic fields are created. For instance, a strong current also generates a magnetic field (and vice versa).
@@Desrtfox71 But doesn't electrical resistance also reduce at high temp in metals? so how can induction work?
@@Veiss7 You just need a current to provide a magnetic field. Currents actually increase when you have a decrease in impedance/resistance. Here's a little info from Wiki on it: en.wikipedia.org/wiki/Electromagnetism
And one other smaller link: www.physics.org/article-questions.asp?id=64
Here's another link, this time to an experiment to replicate the effect in a small model: ua-cam.com/video/rAYW9n8i-C4/v-deo.html
Just to give some other info.
This effect is based on the fundamental principles of electromagnetism, and is well known.
@@Desrtfox71 that experiment shows no data just people talking next to a machine... in any case do you have some evidence to show magnetism in flowing magma?
The article use math and theories but I haven't seen any data or evidence.
@@Veiss7 The Earth's core is not made up primarily of magma. The core is made up of iron primarily, and then nickel. I trust you don't need me to provide evidence of conductivity in such materials?
Here's a breakdown of the composition of Earth: www.iupui.edu/~g115/mod04/pop02.html
Nevertheless, here's a plot showing iron's conductivity by temperature:

Also, I'mg getting the impression that you're less concerned about understanding the science here, and more interested in simply arguing. I have better things to do than argue with someone who will not do the most basic research to educate themselves. Assuming I'm incorrect, here's a good link to find all the evidence based information you need on magnetism, electromagnetism, the Earth's composition, and the Earth's dynamo effect:

So why ain't we able to to levitate by making a platform of a magnet pointing same direction as the earth's pole ... To create a separation from the earth or resistance... Hummm i wonder....
May be there is not such a thing of magnetic field ... Or if it is so it may not work exactly as we thing ... So that being said this experiment or anything similar to this wont tell us much ...
Or simply put... there are two forces at play. One is magnetism and the other is gravity. They are not the same thing at all. If there was only magnetism, then non ferrous materials would be unaffected. Yes?
Wonderful demonstration! Something I had not considered before, Thank you.
Magnetospheres exists on ALL large bodies....not all large bodies have iron/nickel cores....ergo it’s not likely an Iron/Nickel core causing the magnetosphere.....
I think that ruling out the iron and nickle core in Earth as the source of the magnetic field is kinda a jump in logic. Just because other large bodies don't have a core of iron/nickle but do have magnetic fields doesn't mean that the one in Earth isn't the cause. All it does mean for certain is that iron/nickle cores aren't the only source of magnetospheres. It just sounds like you're trying to suggest some kinda of supernatural cause or something
@@thefoxamongwolves9843 right. And my point in making fun is... we don't know. It's just a guess.
@PST3K NaN we do know. While being unable to directly observe, you can take other measurements such as Earth's diameter and calculate it's mass. From those you can come up with a density for Earth. You compare the density to the surface materials and seismic data and you can get a picture of how the layers are set out; with lighter materials "floating" on denser ones. From that we can calculate the mass and size of the core and from that we can min what materials it is made of. Something heavy and common; iron and nickle. So while yes, we've never seen it in person, we don't need to.
I learned something new today. Thank you!

Brimannn cool, wheres the sphere?
I took the arctan(x/z) for the values shown at 6:17 and I got 69.31 degrees of tilt. This is assuming the probe was perfectly level to begin with but it fits with the other measurements of about 70 degrees.
You can also do this with the raw values from the magnet sensor in your smartphone. arctan(Z/Y) and you get the inclination if the phone faces north (X=0).
Now THAT was fascinating.

It's fascinating that because the real 'north pole' is located so incredibly far beneath the 'north pole' anywhere outside the tropics the magnetic field is largely aligned downward. It's also showing off some cool equipment that can make such amazing precise measurements.
Awesome video man. Im writing a book currently that uses this is a world power source. its "fiction" because im not an actual scientist. BUt i think i figured it out.. (so far only works on a small scale.)

@@clusterfork Why not?
actually im talking about an ionic generator. Lined up properly , taking in account the pull of the planet and the magnetism points of the earth, i believe its possible. if lined up properly. but im also talking about a fictional part of a fictional book, so you know.. who really cares if it would actually work or not.
The reason the compass on the globe shows an angle of around 80 degrees while the ball and probe say 70 degrees is most likely because magnetic north is currently in Canada, so the hemisphere would need to be rotated slightly to align magnetic north with the magnet.
My old professor studied geomagnetic anomalies, and had a magnetometer sensitive enough to detect a bus travelling 100m away. It used a coil with 120,000 turns.
Much congratulations on reinventing the dipping compass
Excellent video, have you seen the 3D compass on Grand Illusions?
No, but I sure will now :D Thanks for the tip.
The earth is clearly not flat peoved by this
Peoved. Clearly.
Yeah we need more peofs
I was surprised how accurately you measured the inclination with just a magnetic ball marked with a marker.
Wow - great video. I was just talking to my pre-teen about magnetic polarization and its role in proving the theory of continental drift. This video will be a great way to help him understand!
nice
F71 that's a 7000 USD device and hence Denmark tech-tax level and another +25% VAT on top' we are closer to 10.000 USD so not cheap too say the least.
Solid donation from Lake Shore and imo one of the best magnetic channels on youtube..so very fitting and congrats with it Brainiac and thx Lakeshore for the channel donation thats a nice tool for the viewers to keep track of the magnetic force.
but I would love if you could check such a lab grade Teslameter-device vs. everyday Teslameter sensors, like fx in Ipad etc. that also have these Gauss and Tesla and axes-values {X,Y,X], just to sense how solid are these everyday sensors on of course only small magnets.imgur.com/a/DZdRRjq
I found this example interesting, absolutely. However, when removing the magnetism from our tools, we use heat, a torch. We remove magnetism with heat because heated iron can't be magnetic. Since we've known that for a few hundred years, I wasn't surprised when the "Electric Universe" guys found the cylindrical field, apparently created by the Pedersen current moving through the Earth crust. From what I understand, all of your findings from your measurements are accurate for the cylinder model. The only thing different today, from when I studied it in 1969, is that today we know it isn't a molten core causing the field, it's energy pumped into our crust by our star, which, unfortunately, is dimming and it's electron output has, 1) converted to proton emission, 2) is dimming even as we watch this video.
While we enter a very powerful cold spell of, probably, 150-years, or more, at which time our star will have created enough atoms of Tritium and Deuterium (isotopes of hydrogen) to begin burning that, again, and our weather will, basically, return to what it was 70 years ago when I started looking at this issue. Apparently, astronomers call this the helium flash, and ice-cores, and tree-rings tell us this cycle happens about every 400-years and on one occasion, I saw it end (the ice) after 56-years and in the worst, it lasted 156-years. That was long ago and the ice was three miles deep over Michigan when that rock landed there making that strange crater. Several other times, ice-dams along the Canada U.S.A. border, caused floods of water (ice-melt) miles deep to rush over the American bad-lands area, 60MPH, creating vortices that scoured out those impressive standing tower formations while the water raced toward Oregon and the ocean. Actually, our evidence indicates it happened, at least, four times.
Don't worry, it's cyclical and will be normal again one day...and then it will happen again, and again.
this is obvious to anyone who has spent even a few moments thinking about it.
Cool. This is an experiment, though. Not in your head.
@@mr.h4267 an experiment to prove something obvious
@@KR-ze6oh The hubris on this guy.
@@KR-ze6oh What other stuff is obvious to you that you're not telling us about?
@@mr.h4267 pretty obvious that you are a troll and liked your own comments. great work there guy
Last.....
I learnt more from this video than I did in my entire time in high school!
This explains the clockwise and counter clockwise motion of water vortices at the equator
Great work!!
The Earth is Flat.
We don't care.
I'm from Mindanao, Philippines. I live near the equator. This is a very good educational video for us. Thank U and happy new year...
Instead of the flat plate for the spherical magnet you could use an oiled parabolic surface. Set the magnetic sphere on the slope and release. After oscillating in ever decreasing arcs in the dish it should align with the earth's magnetic field at the bottom.
Very good video, keep creatng valuable content ;) Also that litlle advertisment of that Tesla-meter was really pleasant to watch
Very interesting. I wasn't sure of the point of this video at first but I'm glad I stuck around.
Set this up as a long-term experiment with a live video feed (recorded as well) so when the poles reverse, we can watch it on the sphere experiment ;)
... this was in recommended for some reason and i click on it. "HI!!!!! Have you ever wondered about the direction of the earths magnetic field????????"
Acording to measurements the angle is:
angle = atan(0.0464/-0.0181) = -1.19865 radians or -68.68992º.
the negative means that the north pole of the instrument is aligned to the north pole of the field
Color television picture tubes (cathode ray tubes, CRTs) were designed for either northern or southern hemisphere use to minimize the possibility of color impurities in the picture. However, a CRT designed for one hemisphere could be used optimally in the opposite hemisphere by mounting it upside down. Some sets sold in the southern hemisphere were manufactured this way.
I knew the fields run round the earth top to bottom. This was a great way to demonstrate it. Great job. Maybe add something about the difference between true north and geographic north.
if you dig a little deeper you also find that map north and magnetic north are in different locations. what we consider to be the north pole is the center axis of earth where as magnetic north is where the magnetic field converges.
When I was a little kid I asked my dad, Paul Pantone, the inventor of GEET, how to make magnets. He taught me how to attach an antenna to the north terminal of a battery at this relative angle to charge the battery. Have you heard of that? Tried it?
This is called the declination angle for your locality, it can be looked up in USGS booklets.
These are some physics lessons I needed in school.
