I am somewhat concerned about your measurement of a magnet's volume. Are they really ideal cylinders? I would probably try to measure via displacement of water.
Yep, the Germans know how to do things properly :) Of course they need a kitchen scale weighing with one gram precision up to 15 kg. Say hi to your father from me and thanks for watching!
As a German I have to say we definitely need those scales! Imagine cooking a huge pot of Grünkohl (kale) and not being able to calculate the exact amount of salt that needs to be added.
I am not at all surprised, it was a German company that designed a scale with those specifications. Germans do things properly - not in a sloppy manner ;)

@@Cautionary_Tale_Harris i also thought about adding a aluminum sheet between the scale and the magnet to block the magnetic field. maybe with a little Styrofoam spacers.
@@Francois_Dupont alu won't block the magnetic field. It blocks electromagnetic radiation above a certain frequency but has no effect on a static magnetic field. Try it at home if you have a magnet.
@@raykent3211 sadly i have some magnet, but no alu sheet. hahaha. i always thought it would block a magnetic field. i would have a magnet on one side and it coudnt affect visibly another magnet on the other side. it was 20years ago so i dont remember exactly the setup. maybe it weaken the field so much?
A floating object displaces its weight in water. A submerged does indeed displace its volume in water. You could use a boat of some kind, of which the weight is known, but it is probably adding more variables and so more error in the answer.
Yep, this is how to do it. Straight in the water to get the volume, floating in a boat to get weight. And with the right setup you can get extreme precision at any weight.
Yes there was some playful mystification here based on the measuring device being affected by the magnetic field. Nice entertainment, but otherwise dumb. Just weigh it with a classic balance containing no ferromagnetic material.
@@raykent3211 The problem, as shown with previous videos, at the magnet strengths he has, even non-ferromagnetic materials are still subject to generating paramagnetic fields in them. I recall one video using the magnets to push some things away, in little boats, because the item in question (he tested a bunch) were generating a repulsion field instead of an attraction field. So he's down to making a set of scales out of wood or rope or something, and that's actually a lot harder than you'd think. :-(
@@llearch use a keeper to contain the magnetic field enough for its influence further afield to be négligeable? By keeper I just mean a ferromagnetic enclosure. Like the classic soft iron bar between the poles of a horseshoe magnet, when it's in place the magnetic field is short circuited and the assembly hardly even attracts iron filings.
@@raykent3211 I'm not sure the big magnets wouldn't stick to such a thing, if not be strong enough to permanently magnetise it. Certainly I wouldn't want my fingers anywhere near it. >.< Worth a thought, tho.
3:00 I think you should be fine with smaller spacer as well, as the magnet effects will cancel out, it will 'try' to move the top plate to the magnet, but once the magnet is not in your hands but sitting on the spacer, it will push the plate back where it would be. EDIT: though maybe not if the magnet pulls on the things below the movable plate...
Brainiac75 ,if the issue or error is related with Magnetizations, then first demagnetize it ( a sample pice ) by heating ,then measure the weight. It will give you more accurate value of weight without any error or using spacer
I think measuring the strength of a magnet would require measuring its pull force against gravity. I bet you can think of a setup with a scale that can get this done. The weight of the magnet should not be factored in (especially since you don't know which parts inside the scale are magnetic and therefore whether these magnetic parts somehow influence the mechanical measurement of the scale itself).
You're welcome :) With my Danish accent muddying some pronunciations, I always put English subtitles on. Especially useful for the more uncommon words I sometimes need to use. Thanks for watching!
you could get a dynamometer, like a hanging scale, tie a string to it, like 5 metres long, and put a wood basket at the end of the string, and now you can keep the magnet very far away from the scale
It should work, but a lot of work for a 13 kg magnet. But done carefully, it may be a way of spotting tiny weight differences during pole switching. Thanks for watching!
Weighing a magnet is easy, just tie it to a rope lift it and measure the force with a force gauge, nothing metal nothing close nothing to influence, just easy readings.
That intro... Is a VERY Good demonstration of why these monster magnets are freaking dangerous. A finger under there would've been a goner. Demonstrate with a fake sausage next time! IT MUST SQUIIIRT! Also include a ketchup packet inside it.
Hehe, imagine the clean up I would have to face with a ketchup packet x) Will make for a great recording in slow motion though. And yes, these magnets are not a joke. It is so deceiving that you get the magnet closer and closer without anything happening. And then suddenly, WHAM, everything happens faster than you can react - like the Ketchup Effect...
@@brainiac75 Very much so. They're so unintuitively dangerous. If you forget you're dealing with monster magnet. When I saw the video of "weigh a magnet" Im like OH NO HALF OF THAT STUFF INSIDE IS METAL, WATCH OUT! xD
When I saw the N45, N48, and N52 near each other in the same frame, I nearly died! Until I worked out it was a screen effect. Phew!! I guess you've taught me well! Plus, I've had my own "experiences" with slightly smaller magnets of similar grade.....
1:44 I have noticed with my bath scale, not sure if every works like that, but if I alter my weight by less than 0.5 kg, it rounds the measurement to the last value (I guess to look consistent)? It is funny, because if I add 2kg and remove 1.9 kg, it shows my original weight +0.1 kg but if I simply add 0.2 kg, it just shows the previous value. Btw, I think it is best to get the old balance scales, they work surprisingly well (though, if you want to be really precise, you should use them in vacuum chamber or use weights with similar density to the measured object:p
I just got my first magnet off of Ebay yesterday, 0.5x1x2in bar magnet, advertised as N52 and with a chip and a scratch. I think I got a good price, it was $20 for an impressive magnet like this, it said 4.5kiloGauss. You inspired me to get it, its been fun seeing things that are magnetic, like the dollar bill.

@@EgonSorensen true, but costly! Cheaper is to short circuit the magnetic field with a "keeper", a piece of iron going between the poles. With that there is almost no magnetic field spilling out further in space. Age old tradition. Of course it's trivial to measure the weight of the keeper and subtract that from the total.
Your "problem" is that the measurements are approximations, because your center of gravity is not 100% the same on any of the measurements... You're hand-handling the weights, so the position on the scale isn't the exact same down to the micrometer.
Just one gram? Bah, that must be a scale for immigrants to Germany. Real Germans use plank masses when they're cooking. Can't have food weight more then the recipe dictates. One must fallow the instructions to the last microgram. There's a reason people talk about British and french cuisine but not German. You need a physics, a math and a chemistry degree just to qualify for cooking school.
You could use semi digital lever balance. Make seesaw with a counterweight on one side and scale under it. Then you can put the magnet on the other side and see by how much the weight decreased. And you can adjust the leverage to get multiple times the precision of your scale
Can't the coating be a factor too? I mean as far as I know the shiny outside isn't neodymium itself... So there might be some variations based on manufacturing process (of coating alloy and its application to the surface). That also should be a part of calculation for density....
LOL, there's no need to weight yourself 3 times in a row, because the electronic scales are lying for fast consecutive weightings. It will always show the first number. Unless there is a significant difference in weight or a very long wait between consecutive measurements, the scale will keep displaying the same number. That's a design trick for consumer grade scales, so it won't show each time a slightly different weight when a person weight oneself many times in a row. :o)
Most bathroom scales cheat: if the measurement is within 0.5-1 kg of the previous measurement, they will show the previous value. I suspect this is to make them seem more accurate than they really are. It is easy to test: you just need a few different weights (water bottles and other cooking ingredients?), and you have to get on the scale with different weights until the reading changes - then you can deduce the hysteresis of your scale.
Just a quick comment on weighing yourself on a scale - setting it on a soft surface, such as carpet, will yeild incorrect and unstable results; an electronic scale works by measuring the compression of a spring (technically a set of load cells) but the soft ground itself acts like a spring, compressing underneath the scale's feet and resulting in not all of the mass's weight being transferred to your scale. If you have a room with a tile floor or cement somewhere you can get much more accurate results, though the precision will still be the same. Hope that helps, the more you know! :)
When you weighted the magnet with the big spacer on the 15kg scale, the magnet was still moving (swinging), ut the scale was showing a stable weight... that makes me wonder if the scale has some logic to show an stable reading, even thou the sensor is jumping all around. At that length, the sensor experiences quite a few grams of force. This might have the effect that if you weight something more than once, you get different reading depending on how you place it on the scale, and how much it is moving.
I've been thinking about that video where your showcased a micro SD card that claimed to be magnet proof. Would ionizing radiation cause bits to be messed up on the card? I think that could make for an interesting video. Anyways, great video as always.
You can just use scale for trucks when measuring the biggest magnets😂😂😂 that magnet looks eager enough to lift one ton easily😁😁😁 can you film something like lifting a car with this little guy??😀😀
Great Video:) Regarding the effekt of earths magnetic field on the weight of the magnet: I think it is to be expectet, that the earths magnetic field should not in any way affect the weight on the scale, because the field (at such small lenghts) is completely homogeneous. A Force can only be seen in an inhomogeneous magnetic field (e.g. close to the pole of a magnet), where there is a non-zero gradient of the potential Energei of the magnet in the field. This is the reason, why the neadle of a compass will only be allignet with the magnet feld of the earth, but not pulled towards on of the poles.
Analog spring scale could possibly work better, like for grocery store fruit and such, and weighing the magnet inside of a faraday cage made of steel plating would decrease the effects of the earth’s magnetic field too
Couldn't you make a wooden fulcrum balance scale on a large scale and then use gram weights to get a more precise measurement? There is also the option of the scales you hang objects from that use springs internally, while not as precise, could avoid interference by creating enough distance between the scale and the magnet. Just two other measure methods that could be used.
Just a thought, if you elevate the weighing scales to a fixed position and suspend an iron bar via rectangular frame positioned on the scales such that there's room to place your magnet under test below, you could then zero the weight of the frame and bar and observe the pull on the bar from the magnet placed below it.
Hi Mikea. No, if you keep it away from other magnets and large ferromagnetic objects it is not dangerous for you. It is a strong magnet though - be aware ;)
Thought you would've tared out a piece of wood before using your little scale. What you can do for more accurate weighing is water displacement in a plastic storage container. Also, you have wide feet.
I would suspect its the position of the tube on the scales pressure pad and not having the centre of the magnet lined up exactly centrally on the top of the tube each time, thats causing the discrepancies?
Measuring strength could likely be done by having a known distance between the top of the magnet and a metal plate above. (I would put a layer of dense foam on the metal plate for some crash and finger safety.) With sufficient distance from the scale itself, then we should be able to see the magnets pull up some of their weight off from the scale. But that also seems like a crude way to measure magnetic strength.
just float it in a plastic tub in a plastic tub and weigh the water that is displaced by measuring its volume! a little soap in the water to break surface tension...
I guess you could weigh it using a spring and hook type scale where you hang a platform off of a spring and then put the object to be weighed n the platform and depending on how far the spring stretches, you get your weight. So long a the tray and everything within distance of the magnet was plastic.
Heh I was just thinking about this the other day when I got one of my magnets too close to my milligram scale and worried I mighta screwed it up by magnetizing any iron in it, like the springs.
You didn’t mention how you measured the volume? Just measure the dimensions with a ruler and assume a perfect cylinder? There may be some error there too!
why not just use a simple lever pushing against the scale to get your more accurate measurement? also, i hope you didn't use the scale after it slammed around on the magnet. scales start to fall out of cal pretty fast when they get banged up
Could you use a scale where the magnet is suspended below and pull the magnet until it releases from a plate attached to the scale with strong rope to indicate weight and pull force of magnet
This question ia not related to the video but i find powerful laser cool but also like to have eyes so where do you buy your laser safety goggles and are goggles from survival lasers reliable becouse these laser goggles are alot cheaper than others Please answer
A tip for everyone who has difficulty remembering the calculation method for calculating the cylinder volume; PIZZA! Yes, PIZZA, PI x Z x Z x A (instead of Pi x R² x Height) ^^
The scales were like "Err. What just happened?"
I got a "Err. Dafuq is that shit?" feeling from it instead lol
It can't be good for the scale.
I guess you could use old timey scales made out of non magnetic materials and lead weights on the other side
I am somewhat concerned about your measurement of a magnet's volume. Are they really ideal cylinders? I would probably try to measure via displacement of water.
I know, with at least my bathroom scale, it is extremely inaccurate on carpet/rugs.

Would the scale show the strength if you placed the magnets on a small platform with supports on the table and not the plate?

why not just use a simple lever pushing against the scale to get your more accurate measurement? also, i hope you didn't use the scale after it slammed around on the magnet. scales start to fall out of cal pretty fast when they get banged up
You could use a hanging/wall mounted scale and hang the magnets 2m away from the mechanic.
That is why we don't have antigrav cars. Need megatons of energy.
Could you use a scale where the magnet is suspended below and pull the magnet until it releases from a plate attached to the scale with strong rope to indicate weight and pull force of magnet
This question ia not related to the video but i find powerful laser cool but also like to have eyes so where do you buy your laser safety goggles and are goggles from survival lasers reliable becouse these laser goggles are alot cheaper than others
Please answer
Hi there! I'm your new fan! Perfect content! 10/10!
Hi Denis! Glad you like my videos. Much more to come on magnets, lasers etc.
I just subscribed today, too!
I look through the universe and multiple universe so god is not furthermore far from us
Awesome.. new brainiac.. love this channel
also why not put a aluminum plate between your magnets and the scale to protect it from the interference?
2:59 Have you thought of placing the magnet on-edge on the tube?
only a German would need to know his own weight with 1g accuracy
Solution: use a scale that doesn’t have any magnetic parts in it
That surely takes a weight off your shoulders.
Hi
I think at this point Germany has turned perfectionism into a sport lol.
5:22 was terrifying before I realized it was a video edit.
Can you suggest a website for buying magnets in the US?
Mans pull like 80 kg without struggle
Can you try to hang them from something and measure it like that
5:18, Wow, didn't know you had 3 hands!!!
*its just a tad cold up there* dont worry not for long
A tip for everyone who has difficulty remembering the calculation method for calculating the cylinder volume;
PIZZA!
Yes, PIZZA, PI x Z x Z x A (instead of Pi x R² x Height) ^^
That was new to me. Guess it works. A for 'Altitude' ;) Thanks for watching!
Immediately the scale says error lol.
I think it's safe to say that you're the Styropyro of magnets.
yep
Hej Dine videoer er de bedste og jeg syndes du skulle være mere populær :)
