Spin-stabilized magnetic levitation. A spinning magnet is levitated via magnetic repulsion above another magnet and stabilized by gyroscopic effect. Spinning top acts as a gyroscope and prevents its toroidal magnetic field from fully aligning itself in the same direction as that of the supporting opposing field of the magnetic base. The weight of the top and the alignment of the base magnet needs to be rather precise making this hard to pull off.
Diamagnetic suspension levitation: Pyrolytic graphite is the most diamagnetic substance known to man. Diamagnetism means slight repulsion between a magnets both poles and diamagnetic material. This repulsion shows up in the form of levitation when an attracting magnet above is at specific height
Diamagnetic opposition levitation: A thin enough piece of pyrolytic graphite will levitate over a magnetic array. The lift comes right at the edges where north and south are making contact. The flux density has a peak in the centre but also around the edges of the magnet.The diamagnetic repulsion overpowers the weight of the graphite and the flux density keeps it from falling off the array if the array and magnets are appropriate sized. Diamagnetic opposition and suspension leviation can be combined. This form of diamagnetic levitation will hold more weight than just diamagnetic suspension or opposition levitation.
Induction levitation with permanent magnets: It is possible to levitate a magnet in a proximity of a conductive material like copper or aluminum by manually adjusting another magnet above. The levitation is made possible by eddy currents. Those currents produce their own magnetic field that resists movement of the magnet. This dampens the system, slowing the movement of the suspended magnet.
Electromagnetic Levitation: The levitation is achieved by cooperative action between large attracting ferrite disc magnet and repelling electromagnets that are controlled by a feedback loop which continuously adjusts the electromagnets in relation to the levitating magnet's position.
Induction levitation with electromagnets is pretty cool. Using a levitation coil, a conductive object can be levitated in the magnetic field. Depending on the metal and power setting you can even boil it mid-air. Aluminum will levitate and melt easily at 1-1.5kw of input power.
Tractor beam effect: when a magnet is spun at a certain rpm rate it is possible to levitate another magnet under it. The spinning master magnet locks the levitating slave magnet at a distance of ~ 5 - 10 mm. The levitation gap can be adjusted by changing the rpm rate. Faster rpm means smaller levitation gap. The tractor beam effect is also much tighter with higher rpm. Copper isn't necessary for the effect, but it helps to stabilize the magnet.
The Meissner effect: When this yttrium-barium-copperoxide puck is chilled down below its critical temperature with liquid nitrogen, it becomes a superconductor and magnetic field lines are expelled from its body. Magnet is able to levitate over the superconductor, but it is held in place only weakly.
Flux pinning: This superconductor is slightly different. There are small imperfections on its surface, which allows magnetic field lines to run through them. When cooled down to its superconducting temperature, those field lines become trapped. This locks the magnet in space above the superconductor. The magnet and the superconductor don’t want to move relative to each other."

Beautiful 👍
2:36 perfect analogy for earth with a ufo flying above it via magnetic levitation smoothly in spite of huge variability in earths magnetic field.
3:59 spinning magnet lock reminds me of some old ufo designs. Hmmm.
How can this not be satisfying to watch the magnets move around? I love this
i think some of the ufo are magnetic covered in liquid metal thats how it can change its shape, and in the center is a silver orb that does it like a core....GEODYNAMO!
Wonderful experiments. Really thought provoking. Nice one 🙂😉
Thanks for this awesome educational video!
Excellent video! :-) Have you tried to make your own bismuth crystals yet,,,i think Bismuth has stronger diamagnetic properties than pyroyitic graphite. Love the supper conductor levitation, flux pinning/quantum tunneling/Einsteins spooky action from a distance :-)
Thank you! I have tried to make bismuth crystals and failed miserably :) I alsotried magnetic levitation with bismuth and I'd say it is easier levitate a magnet on graphite than bismuth. What makes you say bismuth has stronger properties than pyrolytic graphite?
@@MagnetTricks Sorry, i was wrong about that,,,i must have remembered looking at this chart, but now i see it was Bishmuth(III)_iodide. It is the product of the reaction of bismuth and iodine. Hummmm, but it is 5 times stronger than carbon :-)

Hydrazine −201
Bismuth(III)_iodide −200.5
Xenon −43.9

@@INVENTOR3 Far out!! Care to share that chart?
@@MagnetTricks No problem my friend.............. en.wikipedia.org/wiki/Diamagnetism
@@INVENTOR3 Oh man I would like to experiment with bismuth iodide. I can only find it in powder form. Wonder how hard it is to turn it into a solid chunk. Would be super interesting to see some levitation experiments with it.
I feel at one with the universe. I also learned a bit about magnets!
Excellent magnet experiment, i m not alon
very cool, all these different possibilities, thanks!
What's the block under the magnetic tractor beam? Is it a copper block?
So, the copper isn't necessary for levitation, but it helps stabilize the magnet.
4:12 is this not what earth does?
as a kind of an expert in magnetic levitation I approve of this
Hi! Can you please tell me the working of electromagnets at 3:10 and their magnetic strength in gauss/tesla? @magnet tricks
On project at the moment and this answers the questions I have been looking for excellent best regards Bruce B
I will call you 'Levitor' aka the levitation king
Two of those just made my mind go booom. Thanks for these. I have an idea how to apply it now. Been on a fun medical leave for to long n been self teaching myself fun stuff. To me this is magic! Lol understanding it is just beautiful. I have become fascinated with mechanical n electrical engineering.
Fascinating video - really interesting!
Thanks Peter! Also thank you for letting me use your video here! Your channel is amazing!!
Sir repel function chemicals
For the levitating electromagnets around halfway through the video, does it matter what material is used to levitate? Is it producing a magnetic field of its own? Thank you.
That apparatus only levitates the right sized neodymium magnets, and yes the electromagnets and the permanent ferrite ring magnet both produce a magnetic field, one repelling and the other pulling the levitating magnet. It is possible to levitate conducting materials like aluminum or copper with strong enough alternating current, like is seen also in this video (electromagnetic induction). Watch Veritasium's levitating barbecue demonstration for further understanding.
@@MagnetTricks thanks. Im trying to levitate a 50-100 gram object an inch away from the magnet and im trying to figure out how to do it.
I really need a magnetic liquid, powder, or putty since the object that needs to float is uniquely shaped and i need to put it inside. Unfortunately diamagnetic materials dont get enough lift so Im trying to find alternatives
Hello Magnet Tricks - can you invent an apparatus with super magnets to test if a 1 ounce Pure Gold Coin or 1 ounce Pure Silver is 100% Pure and exactly 1 ounce? (and not adulterated with Tungsten or Copper?) Do 1 ounce Gold or Silver Coins levitate by their diamagnetic property? Currently, bullion dealers do up to 4 tests to see if a coin is real/fake, because a single property can be faked, but 3-4 properties can not be. But I would imagine how a bullion coin reacts to Magnetic Levitation would precisely identify it. :) Thanks for the cool videos.
1 ounce gold or silver won't levitate on it's own, but there are ways of levitating those with diamagnetic levitation. Some delegate system where weak repelling effect of diamagnetism can be seen, could work determining whether there is paramagnetic tungsten, because it weakly attracts.
Your video is seriously underated.
how to throw iron away from magnet

where can i get that top?
Amazing video!
Really very nice
nice overview
A lovely overview.
This is excellent!!
This is excellent!!
At the end you picked it up with tweezers and turned it upside down. Could you feel a torque in the tweezers?
I'm pretty sure the weight of magnet can be felt while holding the YBCO or other way around. You can make sure of this from wonderstruckwow channel who filmed this footage (link in description) He seemed like a very helpful and friendly fellow.
@@MagnetTricks Isn't' it just a little bit mind blowing that it could create that torque. (like one of those bags of colored powder hitting you in the forehead).
It's a mindblow for sure!
Awesome 😎
where can one get these magnetic arrays
Unfortunately finding nested ring magnets that fit together nicely is hard.These are custom ordered from apex magnet. Supermagnete has a 20x4 mm disk with 4,2 mm hole, and a 4x4 disk.
@@MagnetTricks are u referring to the 3 ring magnet in the diamagtic opposition demo?
where can pyrolitic graphite be bought at ? for diorama purposes im looking for
search from ebay, if you need bigger piece try K&J magnetics or www.graphitestore.com/Graphite/Pyrolytic-graphite
@@MagnetTricks wow, thank you, but damnnnn !! those things are quite expensive !!!
@@kingtigertank72 Yeah, sorry man, the prices seem to have risen quite a bit especially for the big pieces.
@@MagnetTricks would you, by any chance, happend to know something that works just as well, but cheaper, because that for a hobby is excesive. WOW factor yes but too much money
@@kingtigertank72 Bismuth is the second best choice, not as good as pyrolytic graphite, but able to levitate magnets
Great video
Thank you
Thanks for video!
What is a physical principle in the basis of tractor beam effect? Is there any theory of this effect in papers?
When I posted the video to reddit r/physics to ask about whether i had stumbled upon a new form of magnetic levitation. I first of all got heavily downvoted and the consensus amongst reddit physicist was, that it's nothing new as the forces involved are exactly the same as in spin-stabilized levitation (levitron). This answer left me really unsatisfied. I'm no physicist but from an engineering perspective everything is different about levitron - absolutely everything!
@@MagnetTricks Your effect is definitely unlike levitron. I believe, it is based on vibrational forces similar to forces in Kapitza's pendulum. Other experiments are known that are more similar to your effect than levitron. For example

ua-cam.com/video/Dx_GIvWPHGw/v-deo.html
ua-cam.com/video/UTOU8G9jHA4/v-deo.html
I became interested in the effect of levitation in a magnetic stirrer and did my research on this subject ua-cam.com/video/3BVp3SOXvWY/v-deo.html
In your experiment, it is surprising to me that a levitating magnet can not only be repelled from the drive magnet, but also attracted. I mean, there is a certain equilibrium distance with zero force between the magnets. I would like to understand this feature.
@@andreykuznetsov7442 Did you see these?

@@MagnetTricks No, I didn’t. Thanks for links. It’s interesting.
Are you the author of this article? Or, maybe, did you take some part in this work? Experiments are obviously similar to your experiments.
@@andreykuznetsov7442 No I didn't. The paper is written by a guy called Hamdi Ucar. I saw these in Action Lab's video.
