The device shown here has been called a ferrocell. To be clear, it probably does not show the magnetic field lines. Most likely it shows the specular reflection that results from the iron particles aligning to the magnetic field lines (ua-cam.com/video/pc9ghVd1rsw/v-deo.html). This seems like an active area of interest and there may be some value to the ferrocell even if it doesn't necessarily show the magnetic field lines.

It is very interesting that radio signals visible like aurora above sunspot. Alfven hypothesized that sunspots, whose whirlpool-like rotation had long been known, can act as generators, producing powerful electrical fields as they twirl in the sun's magnetic field. Accelerated by these fields, electrical currents shoot out along the sun's magnetic field lines, heating the ions in the sun's atmosphere and making them glow brilliantly-almost a solar aurora.
The sun may turn into a red giant, and black hole may evaporate away due to Hawking radiation after 10¹⁰⁰ years, but my man will never run out of ideas.

reminded me a physics experiment back from highschool. the setup consisted of a glass sphere with vaccuum inside, as well as a piece of coal in a circuit acting as resistence. over it was a cone with hollow tip, so when the coal was electrified, it generated a beam of light that was actually purely negatively charged. The real show was when two hugeass electromagnets were also powered up, which ultimately curved the beam of light in the vaccuum, bending it all the way into a coil, if my memory didn’t exaggerate the visual in the last 20 years. I thought it was going to be that, but still thanks for rehashing those fond memories from the lab. There probably is a standard name for this experiment device and you - and anyone else reading it - probably knows. but given your content, I’m sure it would be cool both for watching and creating.

Love your channel. I wonder if you've seen Kenneth Wheelers work with magnetic fields. He's probably one of the worlds leading experts on magnetism. Literally wrote the book on magnitism. He makes Ferrocells using optical flat glass. I made one using window pain glass cut in 2 circles. Its so neat to be able to see the field in this way.
That is awesome. Stack layers of glass and ferrofluid for a 3 dimensional representation using "slices." Color the slices to to be able to distinguish the different depths by having each layer use different colors of LEDs. Also try a anti reflective coating on the top glass for less reflection.
Been waiting for someone to do this, thought about doing it myself, was going to cut a cylinder through all sheets and then drop a magnet down the hole and record it. Using different leds likely wouldn’t work well though so not sure if much point. Moving magnet would be interesting with that type of setup.
2:06 Magnets are so cool! I received a magnet set when I was a kid for Christmas one year. I was always experimenting with it. In fact, I snuck my magnet set outside and often took it to my neighborhood playground. I waved my magnets over the sand and was surprised to see these non-living "black things" jump up out of the sand and cling to the magnets! I didn't find out they were iron filings until I was a lot older. I just thought they were magic little creatures (I pretended they were alive) that needed to be rescued from the sand. Lol I didn't keep them because I didn't want my mom to know I took my magnets outside. She never said I couldn't, and I never asked. I just assumed I'd get in trouble. 🤔 Anyway, when I was an adult (or at least pretending to be one... haha), I took a newly purchased magnet out to some sand at a local park. I wanted to show my daughter the same "magic" I experienced. Unfortunately, this didn't go well. There were no magic beings waiting to be rescued from THIS sand!! How disappointing. So, off to the internet to try to figure out why they weren't there. From what I could find, iron pilings are sometimes found in beach sand. I'm assuming, then, the local park didn't use beach sand. Or, perhaps it was filtered to remove such "imperfections" like iron filings. 😡 I was truly upset about not being able to share this magic with my daughter, so I purchased iron filings online and placed them in Dollar store sand for my daughter to find. Lol I don't have a technical, logical, scientific mind. I'm more of the imaginative type. But that's what makes magnets so appealing: they "attract" both left AND right brained people. 🙂
I got a question-at 4:48 we can see the magnetic field lines crossing each other and from what i have learnt in school,they arent supposed to do so. So like why does it happen here??
@@mtndewv It's not about giving credit for the ferrocell. It's about giving credit to Theoria Apophasis who created this set-up to see the magnetic fields so beautifully. He's the one who showed on his UA-cam channel how to make this, how to mix the ferrofluid with the oil, placed between glass, and then putting the LED light all around to show the field-lines as magically as it does. Action Lab clearly saw TA's vids and decided to replicate them, and so they should, even just out of courtesy, acknowledge him and his channel.
There is another channel called AB science that has recently stated that Ken has it all wrong and will be releasing a video soon to prove it. ☹️ hope he’s wrong 😑
@@OrphanRed but that will never happen, because he's not part of the tribe of modern science believer, at best the inventor could get mentioned at the very least.
First off, don’t type “WRONG” unless you’ve got the correct answer and want to share what it is. Secondly, it doesn’t. Magnetic field lines aren’t physical and you don’t see the field lines. You can see the actual lines, but you can see where they are. Like putting smoke into the air. The smoke doesn’t make the air visible, but you can see how it’s moving. Edit: I just checked this guy’s channel out and boy is he full of himself. I’ve never seen someone so confidently wrong as this guy who wasn’t either running a cult, or living in Mar-a-Lago.
For the record, ken is just thouroughly aware that he's a genius. Not the same plane as trump who believes he's a genius but hasn't the brain capacity to back it up. Js...distinct difference from the mar-a-lago
Rebecca Freeman he might truly believe that he’s a genius, but I’ve seen a handful of his videos and I can assure you he is not. And how does a genius post something so vague and open ended as his comment above without backing it up and educating everyone else? Dude loves to talk so I know he’s got the words. You know why he didn’t back it up? Because he’s not on his channel. He’s out here in someone else’s backyard speaking out of his ass and he knows if he tries too hard he’ll get ridiculed and the people who watch his channel will see what a fraud he is.
forma3 He may be, but that’s a claim that needs to be proven. If he’s so smart, why would he comment that something is wrong but not correct the wrong statement and back it up with evidence? And if you’re response is that he doesn’t need to prove anything, why did he go through the effort to call someone else out?
I have to say, you literally inspired me to think of fusion in a different way. At least with magnetic fields and just using size, scale, speed, and stepping it up with a mechanical advantage (gearbox)
This is the best channel ever.. ever since I saw your vid on Facebook I started foloowin you wherever I can find you.. you always blow my mind with these amazing experiments
Graphite powder for lubricating locks is diamagnetic and will also illustrate magnetic fields when mixed in mineral oil in a bottle or a shallow tray. Conveniently, the flakes are reactive to the magnetic field but do NOT all clump toward the magnet at all.
This has been by far the most interesting video to me, thanks for making these kinds of videos. Not everyday we see someone do this let alone get famous with it! Keep the improvement going!
Greetings my friend! First of all, I want to salute you that indeed, such amazing job and wonderful experiment you've had carried out here and am sure this very short yet powerful clip does finally solved a long-standing doubt and a straight solid answer to the point which has been much disputed among the scientific research field, Bravo! Anyways, here's a personal question out of my curiousity that I would love to bring out to you James, or perhaps everyone for a fun discussion/ consult. So here's my question :- **How far can a magnetic field bend light? Could it be bent enough so that it goes around a three dimensional object and comes out (after going 180 degrees, I guess) the other side, being bent by the magnet, therefore making it seem as though the object had the light bass through it completely, and it does not appear to the human eye? Here is the best example I can give: -->=light, O=Object, *=mag. field, / or \=light bent. **___** |***| If this can be done, please tell --->/*O*\---> me how, and what would be needed to perform such a thing. ( PS - This would need to be done in a round sense, as in all around the 3-d object, not in just one line, so kindly please keep that in consideration. Also, if anyone know any other way to get the desired effect please feel free to comment or reply me here, CHEERS! )** Wishing everyone good health and may that divine bliss and perfect happiness follow every single beautiful souls here bring endless joy and fulfillment for the rest of your life. Blessed Be. AN'ANASHA!✨❤🌈
super cool, it would be interesting to see the magnetic lines in a picture of single magnets, example, take a picture with only the cilynder, a picture with only an sphecial magnet, etc. Thanks for sharing, awesome work.
nice to see you followed up on my recommendation to explore the ferrocell.. for a more permanent device you need optically flat borosilicate glass and make it sealed..
5:36 You can visualize the magnetic field lines with the aid of an old CRT tv screen. The screen will show the magnetic field from quite a distance and the lines will be colorful.
It was so exciting to see that but was disappointing that I couldn't try it at home , that too it's lockdown here now , so can't really , also don't know how to find ferro fluid
Yes I also did Something super cool. I crushed a magnet into fine powder. It automatically aligns itself with the magnetic field of the permanent magnet. Maybe you should take a look. It is a short.
I would love to see the research and experiment part of your videos behind the scenes. Also I wonder if you have students as interns or assistants. That would be really cool for science enthusiasts
@@B.V.Luminous Doesn't matter who did it first. Not every single person is going to see their video. However, the Action Lab can teach it to many more people. They can do the same experiments over and over again and get the same results, that's the literal premice of how things are proven in science.
This may be off topic, but someone might find it interesting. Over unity electric generator. By AMA. Segment 1: 1 motor with bar connected to it standing vertically. Circular disc connected to bar that has magnets embedded in it surrounded in high permeability material to focus magnets outward pushing force in an upwards direction from top of disc. Segment 2: Hollowed out cylindrical Bar of material horizontally positioned. Flat hollowed out ring shaped material with openings around its outer top flat edge. Magnets surrounded in high permeability material embedded in these openings. Magnets positioned in openings around ring are in at least 1 of 2 configurations either all N magnetic field pushing out or N,S,N,S all around it. Just depends on whether your going for Piston structure or spinning structure explained below & whether you want it to be DC or AC current. Place these all along the cylindrical bar connected to it solidly, except at far ends of bar. At both ends of bar place ring of material that can be magnetically repelled in specific locations. (magnetically repelled in specific location is in reference to outside of ring area that faces away from center of bar)(Other side of same ring facing in towards center of bar is capable of being magnetically repelled all around) Ring must be connected solidly to bar. points of repulsion on these rings is off set from each other on each end of bar. 3 Hollow ring structures with small square bars protruding from each. Ring structure has all magnetic repulsion on inside of ring shape & can rap around the main bar so that the bar wont be causing friction on things as it moves back and forth or spins. 1st positioned around far left of bar, 2nd position at center of bar (be sure to leave enough room for magnetic structures to be able to move back and forth without hitting it) & 3rd positioned on far right of bar. Tube structure is constructed in two parts that fit together on top of each other length wise over main structure. Tube structure has 3 square openings for the bars that the Ring structures that are connected around the main bar keeping it from causing friction on structure, to slide into. This tube structure is designed with material that does not block magnetic fields. Perhaps some type of transparent material glass or other. At both ends of the tube structure there is a built in circular groove that will house a round disc. The ceiling/floor/left side/& right side of groove has openings for small magnets to be embedded in it, so that the pushing force from magnets is pushing in towards the edge of disc that goes in this spot. There is also 4 openings located on the top, bottom, left & right positions of the open groove. Small magnets are placed in these spots so when round disc is in position these magnetic fields will hit sideways keeping it from generating friction against structure. Far Ends of bar has Cap structure that screws over tube halves holding them together. Cap structure also has 4 points on inside top, bottom, left & right that have openings. These openings have small embedded magnets in them that exert there pushing force outwards (sideways) so it will keep disc in position, generating no friction against structure. Cap is made of material like tube so it does not block magnetic fields. (Note: These magnets in groove and cap structure are only needed for piston design. If Disc is directly connected to main bar so as it spins the bar spins, magnets are not needed here). The disc has ring around it (ring of material goes around outer edge and folds over front side & backside a small distance) that is repelled by magnetic fields so the 12 small magnets will keep it lined up but it will be able to spin without causing friction on structure. The disc has openings on it's flat side that face inside of tube and magnets surrounded in high permeability material are embedded in this disc. The disc has small bar that is connected to it's center that goes all the way to the other end of bar structure through the center of the hollowed out bar and connects to disc on other end. Disc on other end is set up the same but magnets embedded in it are off set in comparison. As first disc spins the magnetic fields will push against specific spot on disc connected directly to bar, pushing bar in other direction, once bar is fully pushed over, further spinning of disc will then align the other sides magnet to push it back. Tube structure also has half moon shaped protrusion on inside and on both halves so when tube is connected they line up to make a full ring shape on inside of tube, these half moon shaped protrusions have at least 1 small round opening on it's side in middle of curve that faces away from center of bar. The opening has a small magnet embedded in it so magnetic force is repelling out sideways away from center of bar. The protruding ring is positioned to line up slightly further in towards center of bar then the ring of magnetically repelled material connected directly to bar. This way when bar moves right or left it is magnetically stopped after a short distance. Copper coil setup: Copper coils are wound in at least 1 of 2 ways. Either coiled in circles next to each other (Like if you wound coils around a cylindrical bar) or laid out in a row as if wire was on flat table going up then bent to go down & back up until it formed a flat rectangle of wire bending up and down and then the entire structure folded around tube. Copper windings are then lined up perpendicular to magnetic fields on outside of tube. Ends of copper coils are connected into separate construct that will allow electrical current to flow somewhere else. Circular construct is built like a stand that goes around the outside of motor segment. Circular construct has flat ring of high permeability (magnetic field shielding) material that has small openings that will allow magnetic fields through specific locations. Top of circular construct has groove to allow the horizontal bar to balance on. Circular construct can also be placed on other end of bar so it is balanced. The motor segment is positioned so the disc connected to the bar that is connected to the motor is lined up so the disc passes under the horizontal bars disc that is at end of horizontal bar. The high permeability material keeps the magnetic fields in disc from hitting into the disc that spins or pushes the horizontal bar until just the right moment when the impact will cause the disc in horizontal bar to spin which will perpetuate the piston motion in the horizontal bar. More horizontal bars of the same design are built and positioned around the motor segment in a circular horizontal fashion all the way around. The bar connected to the motor can be increased in length to desired height (As much as motor can handle) and more of the exact same setup is repeated higher and higher up, maximizing the over unity potential of the construct to ridiculous proportions. :D Current from the horizontal bars is diverted to power the motor as needed and all other current is diverted to power my game console or the world. :) Interesting variation to this design would be to connect the spinning discs on far ends of horizontal bar to main bar that magnets are connected to so the magnets spin instead of getting pistoned back and forth. So long as moving magnetic fields are perpendicular to copper wires it should work. By AMA
I think its pretty significant that magnets can hold up more weight than the size of the magnet itself simply because it loops though every piece it attracts.
Thanks for That! bu t i really hoped that u show the magnets polarity, where is north and south. also explain the in and the out of the magnetic field. and why the paper didn't show the magnetic lines as the previous setup!?
3:50 use “optical glass flats”. You can buy them pre-made at incredible flatness. Then you just need a tiny bit of ferrofluid and an eyedropper of WD-40 smashed between the flats.
5:07 thanks, that's useful for finding shite before drilling , except for that plastic crap ducts, but hopefully with strong magnet, I can find the copper wires

I didn't find out they were iron filings until I was a lot older. I just thought they were magic little creatures (I pretended they were alive) that needed to be rescued from the sand. Lol I didn't keep them because I didn't want my mom to know I took my magnets outside. She never said I couldn't, and I never asked. I just assumed I'd get in trouble. 🤔
Anyway, when I was an adult (or at least pretending to be one... haha), I took a newly purchased magnet out to some sand at a local park. I wanted to show my daughter the same "magic" I experienced. Unfortunately, this didn't go well. There were no magic beings waiting to be rescued from THIS sand!! How disappointing. So, off to the internet to try to figure out why they weren't there.
From what I could find, iron pilings are sometimes found in beach sand. I'm assuming, then, the local park didn't use beach sand. Or, perhaps it was filtered to remove such "imperfections" like iron filings. 😡
I was truly upset about not being able to share this magic with my daughter, so I purchased iron filings online and placed them in Dollar store sand for my daughter to find. Lol I don't have a technical, logical, scientific mind. I'm more of the imaginative type. But that's what makes magnets so appealing: they "attract" both left AND right brained people. 🙂
Omg thank for this😉
I got a question-at 4:48 we can see the magnetic field lines crossing each other and from what i have learnt in school,they arent supposed to do so. So like why does it happen here??
Class10 👍🏻
I am fascinated with butterfly flight - especially when they fly against a 20 mph head wind. This video was a great source for renewed visualization.
I am only 15 years old but I love to watch your videos , thanks for giving me knowledge👍
Ken wheeler has been doing this for a looooong time with his ferro cells over on his channel.Theoria Apophasis.
I was looking for the Ken Wheeler comments. He's done a LOT of explanation. I understand some of it. Lol
TIPS: Spraying material will produce a smoother surface than wiping, plus topcoat the ferrofluid with clear acrylic lacquer and it won't oxidize.
The Action Lab, the only UA-cam channel which actually does what it says in the title...
This is so fascinating it made my jaw drop. I just sat there, mesmerized, like NO WAY...
What happens if you feed ferrofluid to a venus flytrap?
Or water some celery with ferrofluid?
Ferrofluid is oily. It won't water the plant.
@@kofeaclarrinfea9877 water-based ferrofluids exist.
Imagination of scientists about magnetic field (diagrams) are TRUE. Students quickly understand from your video. Great Work, Very nice.👍
Can Magnets bend laser light....?
He is really too smart ... finding iron nail with magnetic film is clear expression of his thought and concept clarity ! .. Kudos!
You should have credited Theoria Apophasis for this! This is his work you're replicating.
But wasnt it Timm Vanderelli who created the ferrocell? Genuine question.
@@mtndewv trademark link from ferrocell(dot)us website say you're right, but has Ken Wheeler acknowledge on the site.
@@mtndewv It's not about giving credit for the ferrocell. It's about giving credit to Theoria Apophasis who created this set-up to see the magnetic fields so beautifully. He's the one who showed on his UA-cam channel how to make this, how to mix the ferrofluid with the oil, placed between glass, and then putting the LED light all around to show the field-lines as magically as it does. Action Lab clearly saw TA's vids and decided to replicate them, and so they should, even just out of courtesy, acknowledge him and his channel.
There is another channel called AB science that has recently stated that Ken has it all wrong and will be releasing a video soon to prove it. ☹️ hope he’s wrong 😑
@@OrphanRed but that will never happen, because he's not part of the tribe of modern science believer, at best the inventor could get mentioned at the very least.
Those magnetic lines were absolutely gorgeous. 1000 times better than those crude drawings in my physics textbooks. Very cool. Very cool. Thanks ❤️❤️
"To be clear, it does not show the magnetic field lines,"...........WRONG
First off, don’t type “WRONG” unless you’ve got the correct answer and want to share what it is.
Secondly, it doesn’t. Magnetic field lines aren’t physical and you don’t see the field lines. You can see the actual lines, but you can see where they are.
Like putting smoke into the air. The smoke doesn’t make the air visible, but you can see how it’s moving.
Edit: I just checked this guy’s channel out and boy is he full of himself. I’ve never seen someone so confidently wrong as this guy who wasn’t either running a cult, or living in Mar-a-Lago.
For the record, ken is just thouroughly aware that he's a genius. Not the same plane as trump who believes he's a genius but hasn't the brain capacity to back it up. Js...distinct difference from the mar-a-lago
Rebecca Freeman he might truly believe that he’s a genius, but I’ve seen a handful of his videos and I can assure you he is not.
And how does a genius post something so vague and open ended as his comment above without backing it up and educating everyone else? Dude loves to talk so I know he’s got the words.
You know why he didn’t back it up? Because he’s not on his channel. He’s out here in someone else’s backyard speaking out of his ass and he knows if he tries too hard he’ll get ridiculed and the people who watch his channel will see what a fraud he is.
@@rdear lol Ken Wheeler is a genius regardless of his personality.
forma3 He may be, but that’s a claim that needs to be proven. If he’s so smart, why would he comment that something is wrong but not correct the wrong statement and back it up with evidence?
And if you’re response is that he doesn’t need to prove anything, why did he go through the effort to call someone else out?
Ok so I just want to point out that this is the best way to find studs in a wall that I have seen yet. I love it.
If you stacked a bunch of those ferrocell plates on top of each other would you be able to see the 3D structure of the magnetic field?
Fascinating how humans just get creative enough to be able to see magnetic fields for example.
I love all his videos. Way better than science class
Best magnetic field visualisation ever!
I'll say your DIY glass contraption is a much better and much sensitive tool. Awesome work!
I have to say, you literally inspired me to think of fusion in a different way. At least with magnetic fields and just using size, scale, speed, and stepping it up with a mechanical advantage (gearbox)
This is the best channel ever.. ever since I saw your vid on Facebook I started foloowin you wherever I can find you.. you always blow my mind with these amazing experiments
Seriously this is awesome experiment, it helped me understand the concept more deeper
Graphite powder for lubricating locks is diamagnetic and will also illustrate magnetic fields when mixed in mineral oil in a bottle or a shallow tray. Conveniently, the flakes are reactive to the magnetic field but do NOT all clump toward the magnet at all.
This has been by far the most interesting video to me, thanks for making these kinds of videos. Not everyday we see someone do this let alone get famous with it! Keep the improvement going!
If you aligned magnets into a Mobius strip, where would the poles be?
This is a call to action to make this amazing model better
Wow the light one was very cool
This guy never run out of ideas
Greetings my friend! First of all, I want to salute you that indeed, such amazing job and wonderful experiment you've had carried out here and am sure this very short yet powerful clip does finally solved a long-standing doubt and a straight solid answer to the point which has been much disputed among the scientific research field, Bravo! Anyways, here's a personal question out of my curiousity that I would love to bring out to you James, or perhaps everyone for a fun discussion/ consult. So here's my question :-
**How far can a magnetic field bend light? Could it be bent enough so that it goes around a three dimensional object and comes out (after going 180 degrees, I guess) the other side, being bent by the magnet, therefore making it seem as though the object had the light bass through it completely, and it does not appear to the human eye? Here is the best example I can give: -->=light, O=Object, *=mag. field, / or \=light bent. **___** |***| If this can be done, please tell --->/*O*\---> me how, and what would be needed to perform such a thing. ( PS - This would need to be done in a round sense, as in all around the 3-d object, not in just one line, so kindly please keep that in consideration. Also, if anyone know any other way to get the desired effect please feel free to comment or reply me here, CHEERS! )**
Wishing everyone good health and may that divine bliss and perfect happiness follow every single beautiful souls here bring endless joy and fulfillment for the rest of your life. Blessed Be. AN'ANASHA!✨❤🌈
That's the most amazing video from you. Love your contents. Keep teaching us new stuffs like these.
This is one of the best video on this channel
super cool, it would be interesting to see the magnetic lines in a picture of single magnets, example, take a picture with only the cilynder, a picture with only an sphecial magnet, etc. Thanks for sharing, awesome work.
look for Theoria Apopahsis he did loots of video on the ferrocell
Hey action lab congratulations for 3.2 M subscribers.😀😀😀
Visualization of magnetic field is really awesome
This is an outstanding demo. Never saw magnetic field lines this clearly.
That's the most amazing video on magnetism I have ever seen
DUDE!! You made my jaw drop with that light setup.
That last little hard about finding nails in the wall would make a great stud finder!
This is his one of the COOLEST videos ever!!!! 🔥🔥
Finally another channel talks about these!! I have two and they are AWESOME!
nice to see you followed up on my recommendation to explore the ferrocell.. for a more permanent device you need optically flat borosilicate glass and make it sealed..
Whoa! That looks really cool. Would like to see this with magnetic breaking. Might need slo-mo, though.
Just looking at those magnetic field lines is soo damnn satisfying
It could be very useful using that experiment in physics labs 👌
This should be a practical in schools when learning magnetism.
You are simply amazing person
Thanks for telling us modern way to verify magnetic field lines
5:36 You can visualize the magnetic field lines with the aid of an old CRT tv screen. The screen will show the magnetic field from quite a distance and the lines will be colorful.
Outstanding! I will be trying the ferrofluid trick!
Thank you so much for this path light demo
It was so exciting to see that but was disappointing that I couldn't try it at home , that too it's lockdown here now , so can't really , also don't know how to find ferro fluid
Yes I also did Something super cool. I crushed a magnet into fine powder. It automatically aligns itself with the magnetic field of the permanent magnet. Maybe you should take a look. It is a short.
The Action lab favourite line
: Thats so cool😀
Very cool experiment
That nail trick looks like it would work to find stud locations in the wall where sheetrock is screwed to the studs!
Just subscribed because my 4 year old loves watching your videos
I would love to see the research and experiment part of your videos behind the scenes. Also I wonder if you have students as interns or assistants. That would be really cool for science enthusiasts
ua-cam.com/video/RMToXnxDgg0/v-deo.html
This person did it first.
@@B.V.Luminous Doesn't matter who did it first. Not every single person is going to see their video. However, the Action Lab can teach it to many more people. They can do the same experiments over and over again and get the same results, that's the literal premice of how things are proven in science.
Thank Goddd. A video of this subject not made by Theoria Apophasis.
Great demonstrations.
This may be off topic, but someone might find it interesting.
Over unity electric generator. By AMA.
Segment 1: 1 motor with bar connected to it standing vertically. Circular disc connected to bar that has magnets embedded in it surrounded in high permeability material to focus magnets outward pushing force in an upwards direction from top of disc.
Segment 2: Hollowed out cylindrical Bar of material horizontally positioned.
Flat hollowed out ring shaped material with openings around its outer top flat edge.
Magnets surrounded in high permeability material embedded in these openings.
Magnets positioned in openings around ring are in at least 1 of 2 configurations either all N magnetic field pushing out or N,S,N,S all around it. Just depends on whether your going for Piston structure or spinning structure explained below & whether you want it to be DC or AC current.
Place these all along the cylindrical bar connected to it solidly, except at far ends of bar.
At both ends of bar place ring of material that can be magnetically repelled in specific locations. (magnetically repelled in specific location is in reference to outside of ring area that faces away from center of bar)(Other side of same ring facing in towards center of bar is capable of being magnetically repelled all around) Ring must be connected solidly to bar. points of repulsion on these rings is off set from each other on each end of bar.
3 Hollow ring structures with small square bars protruding from each. Ring structure has all magnetic repulsion on inside of ring shape & can rap around the main bar so that the bar wont be causing friction on things as it moves back and forth or spins. 1st positioned around far left of bar, 2nd position at center of bar (be sure to leave enough room for magnetic structures to be able to move back and forth without hitting it) & 3rd positioned on far right of bar.
Tube structure is constructed in two parts that fit together on top of each other length wise over main structure.
Tube structure has 3 square openings for the bars that the Ring structures that are connected around the main bar keeping it from causing friction on structure, to slide into.
This tube structure is designed with material that does not block magnetic fields. Perhaps some type of transparent material glass or other.
At both ends of the tube structure there is a built in circular groove that will house a round disc. The ceiling/floor/left side/& right side of groove has openings for small magnets to be embedded in it, so that the pushing force from magnets is pushing in towards the edge of disc that goes in this spot. There is also 4 openings located on the top, bottom, left & right positions of the open groove. Small magnets are placed in these spots so when round disc is in position these magnetic fields will hit sideways keeping it from generating friction against structure.
Far Ends of bar has Cap structure that screws over tube halves holding them together. Cap structure also has 4 points on inside top, bottom, left & right that have openings. These openings have small embedded magnets in them that exert there pushing force outwards (sideways) so it will keep disc in position, generating no friction against structure. Cap is made of material like tube so it does not block magnetic fields. (Note: These magnets in groove and cap structure are only needed for piston design. If Disc is directly connected to main bar so as it spins the bar spins, magnets are not needed here).
The disc has ring around it (ring of material goes around outer edge and folds over front side & backside a small distance) that is repelled by magnetic fields so the 12 small magnets will keep it lined up but it will be able to spin without causing friction on structure. The disc has openings on it's flat side that face inside of tube and magnets surrounded in high permeability material are embedded in this disc.
The disc has small bar that is connected to it's center that goes all the way to the other end of bar structure through the center of the hollowed out bar and connects to disc on other end. Disc on other end is set up the same but magnets embedded in it are off set in comparison. As first disc spins the magnetic fields will push against specific spot on disc connected directly to bar, pushing bar in other direction, once bar is fully pushed over, further spinning of disc will then align the other sides magnet to push it back.
Tube structure also has half moon shaped protrusion on inside and on both halves so when tube is connected they line up to make a full ring shape on inside of tube, these half moon shaped protrusions have at least 1 small round opening on it's side in middle of curve that faces away from center of bar. The opening has a small magnet embedded in it so magnetic force is repelling out sideways away from center of bar. The protruding ring is positioned to line up slightly further in towards center of bar then the ring of magnetically repelled material connected directly to bar. This way when bar moves right or left it is magnetically stopped after a short distance.
Copper coil setup: Copper coils are wound in at least 1 of 2 ways. Either coiled in circles next to each other (Like if you wound coils around a cylindrical bar) or laid out in a row as if wire was on flat table going up then bent to go down & back up until it formed a flat rectangle of wire bending up and down and then the entire structure folded around tube. Copper windings are then lined up perpendicular to magnetic fields on outside of tube. Ends of copper coils are connected into separate construct that will allow electrical current to flow somewhere else.
Circular construct is built like a stand that goes around the outside of motor segment. Circular construct has flat ring of high permeability (magnetic field shielding) material that has small openings that will allow magnetic fields through specific locations. Top of circular construct has groove to allow the horizontal bar to balance on. Circular construct can also be placed on other end of bar so it is balanced. The motor segment is positioned so the disc connected to the bar that is connected to the motor is lined up so the disc passes under the horizontal bars disc that is at end of horizontal bar. The high permeability material keeps the magnetic fields in disc from hitting into the disc that spins or pushes the horizontal bar until just the right moment when the impact will cause the disc in horizontal bar to spin which will perpetuate the piston motion in the horizontal bar. More horizontal bars of the same design are built and positioned around the motor segment in a circular horizontal fashion all the way around. The bar connected to the motor can be increased in length to desired height (As much as motor can handle) and more of the exact same setup is repeated higher and higher up, maximizing the over unity potential of the construct to ridiculous proportions. :D Current from the horizontal bars is diverted to power the motor as needed and all other current is diverted to power my game console or the world. :) Interesting variation to this design would be to connect the spinning discs on far ends of horizontal bar to main bar that magnets are connected to so the magnets spin instead of getting pistoned back and forth. So long as moving magnetic fields are perpendicular to copper wires it should work. By AMA
Oh my gosh that is soooo cooll!
I’m 12 years old but I love science and its fun to watch your videos because I can always learn something! :-)
that iron paper combo'd with a magnet to find nails in a wall might be good to help carpenters. Maybe idk.
HD magnetic visualizer, amazing
Awesome job on this video. Great way to present magnetic fields
I think its pretty significant that magnets can hold up more weight than the size of the magnet itself simply because it loops though every piece it attracts.
Thanks for That! bu t i really hoped that u show the magnets polarity, where is north and south. also explain the in and the out of the magnetic field.
and why the paper didn't show the magnetic lines as the previous setup!?
3:50 use “optical glass flats”. You can buy them pre-made at incredible flatness. Then you just need a tiny bit of ferrofluid and an eyedropper of WD-40 smashed between the flats.
Incredible! Very cool experiment.
Ok, the finding nails bit (therefore finding likely studs) is something I wish I knew years ago. That's a life hack baby!!!
Nice! I especially like the poor man's stud-finder
5:07 thanks, that's useful for finding shite before drilling , except for that plastic crap ducts, but hopefully with strong magnet, I can find the copper wires
Your videos lately have been really great. Keep up the good work.
