  • hey this is simple , here first liquid nitrogen with very low temp is used as coolant to the superconductor and the magnetic body is placed with a partition above the superconductor, as soon as the superconductor acquire the temp of liquid nitrogen u can see this phenomenon......

  • maybe thats how they moved those large stones, in egypt and lebanon using magnets.

  • @mariaten100 I'm quite sure that they did not have such powerful magnets back then, let alone liquid nitrogen:)

    -only one explanation, Aliens! :P

    herp derp^^

  • It's styraphoam

  • Y U NO FALL?

  • Holy shit - sci-fi authors take note

  • What's the material of the base?????

  • 1:24

    Hey guys look I made a mag-

    OMG YOUR A WIZARD!!!!

  • Flux pinning ftw.

  • so it is liquid nitrogen or what?

    

  • That's amazing, it's like you brought outer space to earth.

  • Burn the witch! The fire will heat the superconductor, and everything will return to normal!

  • Is it me or does it seem like he would freeze his fingers?

  • How does that work.

  • THIS VIDEO IS TOO LOUD

  • WHY YOU NO ABIDE TO LAW OF PHYSIC?

  • some twilight zone shit here!!

  • ohhhh so that's how planes fly ;)

  • Has anyone been able to use this magnetic energy to power automobiles or power to a house. Seems like this could be smaller & available easier than wind or solar. Magnetic power & levitation is very interesting. It'd be cool to lift and propel a vehicle.

  • @swim2win86 there are blueprints to a maglev train that can go up to 4000 mph and runs on nothing but magnest.

  • Could anyone please provide me with any insight into any progress with the application of magnetic levitation in mine hoisting technologies....

  • there's better things to levitate, keywords levitating plant ,look for two min. video

  • ... field is stuck, it can hold the superconductor and magnet is fixed positions. This allows the magnet to float in place, to spin on the spot, and to pick up the superconductor.

    Well, that's about it if I'm not going to go into BCS.

    Post 5/5

  • A final note for the very clever, who are asking why the magnet does not slip sideways, and why it can pick up the superconductor.

    Well, as said, a magnetic field cannot enter a perfect superconductor. But we do not see the superconductor repelled from the Earth's magnetic field! In fact, when the magnet and superconductor are pressed together, regions form in the superconductor where superconducting breaks down. The field penetrates these regions and gets stuck. This is "pinning". Once the ...

  • ... which are cooled by nitrogen, and magnets in a track to levitate a train. More commonly in trains, however, the superconductors are used not for their levitating properties, but to make superconducting wires for powerful electromagnets which then repel one another pole-to-pole.

    So the speculation below about the nitrogen superconducting, or some kind of jet of nitrogen supporting the train is a misunderstanding. The superconducters do the floating. The nitrogen only does the cooling.

  • Following on. A superconductor is so called because it offers no resistance to the movement of electricity. By the same effect, it also perfectly repels magnetic fields. Thus, the magnet cannot sit on the superconductor because of this repulsion.

    This is *not* pole-to-pole repulsions between two magnets. A superconductor repels *all* fields. Two magnets, N to N will flip and then attract. This does not happen with this form of repulsion.

    A train can use on-board superconductors ... (cont)

  • Quick 'how it all works', as there are a variety of misconceptions being repeated below.

    The black substance is a superconductor (YBCO, at a guess). The silver doodad is a rare-earth magnet (likely NbFeB). Any magnet will do, but this is strong.

    The nitrogen is cold: -196 deg C. Adding heat causes it to evaporate, rather than warm up, just like water at 100 deg C. The nitrogen is used to keep the superconductor at a sufficiently low temperature to superconduct.

    Next comment is on levitation.

  • wat is the liqiud you used

  • great allah, thanks for these beauties

  • @slasherzedd You had me for about a second until I realized nobody would write a comment that dumb below a video about physics and science. Good trolling, Sir.

  • @dontryme28191 its liquid nitrogen.

  • What is that liquid?

  • what is that liquid that you pour sir? and how is that it repel and attract at the same time.. thank you sir.

  • it is superconducotr no :D

  • It might be possible to catch an armor piercing bullet (normal bullets are just lead), firing it over a massive and incredibly powerful magnet. They tried deflecting bullets with magnets on the show and it required several super powerful magnets.

  • @silverguy24 If someone developed bullet deflecting vests with super magnets on them, people would just start producing bullets with no magnetic properties. Anyone need any gold or titanium bullets? ;]

  • is the round silver piece the permanent magnet or the black block the permanent magnet?

  • @GraffitiCan I think the silver one is a neodymium permanent magnet

  • ___ w w w diymagneticmotor com has interesting PLANS~

  • maglev cobra brought me here, I hope they do this tecnology soon

  • The Bottom black rectangle is not a magnet, it's a superconductor. When a superconductor is cooled really fast (he probably just used liquid nitrogen to do so), it induces and electromagnetic flux on the surface of the superconductor. This induced current causes the applied magnetic field to go around the superconductor, rather than through it.

  • @SteezeOnSkis its actually not a super conductor. its a piece of ceramic. the fact that it is supercooled makes it a super conductor, the ceramic actually changes properties for a short time.. just one of the many mysteries of physics.

  • @SteezeOnSkis It doesn't have to be cooled fast. In fact, how fast you cool it is of no consequence. The superconducting properties vanish above certain temperature, that's all there's to it.

  • will never be made to work at normal temps though i guess, or will it.

  • This is superconductor and neodinum magnes. If we cold the superconductor by the liquid nitrogen the superconductor makes specify magnetic field which block magnes in this position :)

    Thanks for psychic

  • that was freakin AWESOME!

  • Watch my magnet levitation to do at home

  • thumbs up if you watched it with sound turned off!

  • So what's going on here?

  • if diamagnets are repulsive how is there an attraction when the magnet is lifted?

  • what kind of magnets r those

  • :))))))

  • dammit, that is so fun. wish i could do it in my home, superconductor....looks expensive

  • flux trapping effect!!!!!

  • put your fingers inside the awesome liquid :)

  • @HORRORTV1 LOL anything with a BOILING point of -196 celsius has to be amazing!!! NITROGEN FTW!!!

  • I don't get it !!!! I just can't explain these physics !!!!

  • Very interesting things, magnets.

  • you can just put to opposite poles together and they will levitate! :)

  • @Kurd4Eva101 : No, it must be same poles (N-N or S-S) for the repulsion and than it will levitate

  • @rajesh64727 ya thats what i meant to say

  • AMAZING!!!!!

  • Seems easy enough, just go to go to my local store and buy some liquid nitrogen!

  • SO BASICALLY YOU FROZE THE MAGNETIC FIELD BETWEEN THE 2 MAGNETS,

    THUS MAKING IT LEVITATE

  • what is the dark green thing on the middle??

  • explain me why adding nitrogen prevents the magnet to be thrown apart

  • @gippi86 the nitrogen froze the magnetic field between the 2 magnets themselves fairly simiple

  • @DARKSYSONFTW it froze the magnetic field??? ahahah I hardly think so... maybe it keeps the atom polaraization stronger so that the field cannot be deformed, but it's absurd, the field source shouldnt change anyway. 

  • @gippi86 See now your theory and mine aren't very different all i'm saying is that the liquid nitrogen causes the magnetic field to become... more personal between the two magnetics as you saw both came in contact with the nitrogen but like i said this is only a theory that i have =^)

  • what is the black thing?

  • What does the liquid nitrogen do to make it levitate besides the fact that it creates zero resistance....?

  • @VesperTipz Most superconductors only work at very cold temperatures, like this one in the video. For example, pyrolytic carbon a.k.a pyrolytic graphite (which is not in pencils) is active at room temperature, but is only able to be levitated about a few millimeters off the ground. I am sure there are few others.

  • ESA PUEDE SER LA FORMA EN QUE VUELAN LOS OVNIS o.O

  • And that's how kids, they made the holy ark of the covenant fly...

    NOW GIMME THOSE FRICKIN' FUMBZ UP OR I KEEEEEEL YOUUUUUU!!!

  • i just got mind fucked.. whoa...

  • omg you can see the strings..

  • I am going to sue my school teachers for not showing us the REAL stuff !!! Woww

  • thats how a ufo work!

  • cool picked up eraser

  • FUCKIN MAGNETS, HOW DO THEY WORK?

  • lie

  • fuckin magnets. how do they work?

  • @Zexion72559 when we place the super conductor in liquid nitrogen we have the superconductor below critical temperature. So when it at below critical temperature we made the compound diamagnetic as the temperature lowered. this is a meissner effect when the magnetic field applied to a specimen, currents flow within the outer skin of the superconductor is oppose the induced field, and so producing a zero net field in bulk. so the sample act as magnet oppose the polarity applied resulting levitate

  • @recanaw I'm thinkin that i just got my ass handed to me.

  • @Zexion72559 im just sharing what i just learn in class

  • @Zexion72559 They simple have all of their N poles face in the same direction, and attract a metal that has poles facing in the same direction, but both N and S poles.

  • @Zexion72559 when the liquid gas is poured onto the black solid, it becomes a superconductor. A property of superconductors is that magnetic fields are completely expelled which causes the magnetic force to push the magnet upwards and levitate :D

  • @Zexion72559 i laugh at all the poor idiots who reply to you thinking you were serious

  • @Zexion72559 Meissner effect bro.

  • @Zexion72559 uh... electromagnetism o.o" one of the most basic concepts of physics...

  • @Zexion72559 DAAAAAAAAAAAAAARK FOOOOORCEEEEEEES!

  • I like it very much. I would like to know what is the super conductor and what type is the magnet. If the kit is available where can I buy it. I teach Physics. So I wish I can have the kit for demonstration purpose. Thanks for the video.

  • @dlsastry i just made the superconductor in lab it is YBa2Cu3O7

    

  • lol i did this 2 times at home...once...i spilled the liquid nitrogen....)_)...second time i got it...and i increase the S.A of the magnetic field and added many magnets... XD

  • I know nothing of science, but , do you think this technology can be used to man a space craft made of a magnetic propultion system to propell it through the universe? Since the vasness of space is really cold, would the magnets act as they would in your experiments? even though there is no gravity in space?How can this work, or could it not. This is a very cool magnetic levitation experiment! So many possibilities.

  • @SmokeyMaCPot089

    Very good question indeed ... !

  • @SmokeyMaCPot089 There is a gravity in space, as I understand. Just like Earth attracts Moon; planets, stars and black holes would attract the space ship.

    And in the spaceship case, what would be the "big magnet", like in the video it was the base magnet.

    Maybe it would work, though.

  • i am amazed and really puzzled. one thing i am sure 100% is that magnetic fields and forces is far away from what we learned in school! that simple explanation with north and south poles, N to N repulsion forces and S to N attraction forces and so on is simply too naive "mainstream" explanation ... reality is not so simple!

  • what the fuck they mean with "trapped magnetic lines"!? "magnetic lines" is forces not physical objects not so!? or all mainstream and official explanations of what is an magnetic field is simple bullshit and magnetic current fields IS real objects with strange properties not simple pull or push forces!

  • and Tom H. Johansen explanation for this physical effect for me look like a stupid and quick high school bullshit:

    quote "Movie 3: Lifting superconductor without touching it At room temperature magnetic field lines from the magnet penetrate the superconductor without restraint. After cooling by liquid nitrogen they get trapped by microscopic inhomogeneities in the superconductor. The trapped magnetic lines then serve as invisible threads holding the two objects together at a certain distance"

  • well, for me this little diamagnetic levitation demo is amazing! look like this thing, magnetic field and "magnetic forces", is not simple pull or push forces!

    LOOK LIKE STAR TREK TRACTION RAY TUMBLING DOWN FROM FICTION TO REALITY!!!

    is that thing! a traction ray! because when you push, is repelling, when you pull up the upper magnet, bottom magnet is yanked up as well! is not a simple force! is an invisible and immaterial rope! a very real one!

  • Disbelievers should Google video search (Tesla longitudinal electricity) then watch the entire set of demonstrations presented therein.

    Did your physics programs in school teach you any of the stuff that these guys in the 1970s and 1980s were tinkering with?

    Or that it was invented in the late 1800s, or that the medical Tesla coils used in the demo were from the 1920s?

    Or that Tesla coils had any proven medical applications?

    Ever heard of Dollard, Brown & Lindemann?

    Hmm? Didn't think so...

  • Styrofoam bath container to hold the liquid nitrogen prevents more rapid heat transfer losses to the environment.

    Anyone's disbelief is harbored in the false assumption that our education systems are all inclusive--they are deliberately not so.

    Google (General Education Board Rockefeller)

    Tycoons have prevented thinking outside their box to prevent any paradigm shifts that would halt their established monopolies in energy, government policy, warfare, pharmaceutical drugs, & disease treatments.

  • @afshinkiyani

    it is not a fake, sorry to dissapoint you. the black box is a superconductor. it means that after being cooled under its critical temperature, it expels the magnetic field from its bulk but remains "entrapped" in the magnetic field pattern. you can see it after raising the magnet - the superconductor goes up as well.

    I will perform the same experiment tomorrow in our institute.

  • @dejvice78 just like hydrogen for example

  • the falling is cool) its like the spaceship landing on the planet :D

  • Hover trains, here we come :D

  • Heres what happened. He took two magnets (both are obviously visible), he poured liquid nitrogen in the Styrofoam container with the black magnet, making it a crude superconductor. At that point any magnet will levitate.

  • Very nice. were do i find Info at?

  • čim jsto polyl?

  • r we in limboo???? o-o

  • 1:38 Spaceship has arrived xD

  • i have to watch this FOR SCHOOL MAN!

  • ninja magnets

  • Que video tan fresa!!!

  • cewl........

  • How does the liquid nitrogen cause the magnet to levitate?

  • We don't even need oil.. Oil is probably just gov/illuminati power.. We can use magnetic power and cold fusion to run this planet.. It's possible to clone frogs they say. So i guess it's possible to clone other animals to but they just haven't gone out with it yet beacuse it would solve the whole food problem. Money is just paper and paper is the forrest. And the trees, flowers and all that is (according to science) the only reason why homo sapiens and animals can breath. What do you think?

  • @makasaka i think you r right with that what you write! much greetings from croatia!

  • @makasaka Lol, magnetic power.

  • It's possible to make a spacecraft with magnets. I've heard you can get a magnet to spin so fast it will make the gravity around it fall so the friction will stop existing around the air craft so you can travel as fast as you want. Go check out the "TR3B" That's a AREA 51 project... And it's not good for ous civilians.

  • @makasaka You sir, are a complete idiot. Gravity doesn't create friction of the airplane. Molecules of air do, when they hit the body....

  • @gnidich2000 Yes it does. Not as much as wind, but it can turn the craft's own mass against itself.

  • @gnidich2000 You are a total idiot too. The gravity can create forces that slows the plane. Aluminum vs magnetic forces are interacting. They are not completly neutral.

  • @blu3sh4dow4u gravity can't slow the plane down, its a force acting at right angles to the speed of the plane, in point of face it can only accelerate the plane, however because of the wings (and the lift caused by air travelling over them) this force is cancelled, thus no acceleration

  • @BigPimp238 tell me this after you study about magnetic forces interacting with objects. an example could be the earthquake in japan and Earth - Moon distance. There are also magnetic forces and no interaction at first look. But magnetic forces are more than complex, even to study. The humans exists because of magnetic forces.

  • @gnidich2000 why insult people, just because they dont know?

  • @makasaka ahh I see you are graduate from the university of what-my-old-man-used-to-say, with a PhD in what-some-guy-told-me-in-the-p­ub.

  • wow very kool

  • well i just wanted to ask you what was the paperlike thing you place on the magnet before levitating it ? and what type of magnets are you using in your expirament ?

  • trippin balls

  • ni dat to me !!!!

  • WE WOULD ALREADY HAVE FLYING CARS IF WE COULD USE VERY STRONG MAGNETS THAT WOULD PUSH AGAINST THE METAL IN THE ROCKS

  • @MrDeletedDanger We could use your capslock key instead

  • @GitarStu i had it on by accident

  • @MrDeletedDanger And you didn't realise after the second letter? It's not hard to push. You've clearly worked it out now anyway. In fact, you've gone the opposite way and forgotten to capitalise!

  • @GitarStu i look at the keyboard the whole time

  • @MrDeletedDanger

    possible....we'll figure it out.

  • fucking magnets how do they work?

  • @Quadkillz0000 Dunno. Never seen one fuck?

  • richard saar pwough pwough pwough pwough pwough pwough pwough pwough pwough pwough pwough !

  • HAAAAAAAAAAAAAAAAAAAAAAAAAAAAA­AAAAAXXXXXXXXXXX

  • the black object is just a piece of ceramic?

  • so the force is push upward only? will there be a force pushing downward, as well?

  • @edithlegacy gravity.

  • @ArtofEspeonage so if i were to put a 1kg rock on top of the magnet, would the superconductor suffer downward force via weight of the rock?

  • @edithlegacy Well, I'm no expert on this subject, or how this even works, but if the superconducter is the other rather metallic-looking object(assuming the magnet is the "floating" object), then yes. But the superconducter would not be accelerating due to the normal force from the table/white thingy(lol pretty lame language).

  • @ArtofEspeonage thanks for replying.

  • @edithlegacy No problem. If I was correct, and/or helped you understand something, fantastic! If I was hopelessly wrong, oh well! I'll learn from my mistakes.

  • you could of lost the tip of your finger there bob by diping it in the nitrogen

  • my question is how does it make a magnetic field by just adding nitrogen ???

  • Comment removed

  • @DoodieManish An emf is a voltage not a current. For superconductors resistance is zero (not almost zero) and it occurs above absolute zero. For this material it suddenly becomes a superconductor at 92 degrees above absolute zero. It goes from being a poor conductor to being a perfect conductor at this temperature. Currents are experimentally determined to last in excess of 100,000 years (this bound is expected to be higher - its limited by accuracy of measurement). That's how perfect it is.

  • Comment removed

  • @DoodieManish Since V=IR and R=0 then V=0. So all points in the superconductor are at the same voltage. So there can be no emf, emf=0. Faradays Law is that the emf is proportional to the rate of change of magnetic flux. So there can be no change of magnetic flux passing through the superconductors surface. So induced surface currents must exactly cancel any magnetic field you bring up. But there is more going on than that as you can see in my other comments.

  • @Zantorc

    "An emf is a voltage not a current."

    Not what I meant.

    I said I would keep it short due to restrictions, and I was implying that the induced emf would generate a current.

    Reading what I wrote, I can see how that could be inferred.

    Also, I've always felt uneasy telling someone that a property can reach zero (If the world were ideal and our equipment perfect, I wouldn't hesitate).

    My stance is quite clear. Read and learn on your own as I mention at the end. People can be mislead.

  • @DoodieManish

    And since It could easily be inferred wrongly, I have deleted it.

  • you can get nitrogen liquid ina bout any bottle with air on it,..buy a computer blower and take out the juice by spraying really close into acontainer,..juke the nozzle

  • @oscarvmaldonado B.S. As in Bull you know what! First the inert gas in the air cans of air are not capable of creating liquid nitrogen, second just because it is cold and frosty does not mean it is liquid nitrogen! Liquid nitrogen is a cryogenic fluid not a gas.

  • @BadSmaxx ..sorry dude..just wanted you to xplain..tanxs man!

  • @oscarvmaldonado You can buy liquid nitrogen. I buy small quantities from the local ice cream store, (the type of ice cream shop that makes their own ice cream) he sells me some in a thermos as long as I tell him what I'm doing with it. You can also buy it at or through most welding supply shops, but you end with a lot of it, and you have to pay for the dewar it comes in. (a dewar is basically a wicked efficent thermos)

  • à cause du froids, les métaux deviennent des conducteurs parfaits

  • where in limbo :O

  • comment tu fais?

  • Burn the witch!

  • @LOCUkDk XD

  • WTF

  • COOL!!!!:)

  • where did i get nitrogen liquid?
