Creation of Magnetic field....
Briefly, magnet on top and superconductor on the bottom. When the superconductor is cooled with liquid nitrogen, it induces magnetic dipoles which oppose the magnetic field and repel the magnet. The reason the magnet does not slip off, is because the superconductor is impure. Magnetic Flux Tubes become pinned to the imperfections of the superconductor, holding the magnet in place (Flux Pinning).

By kirks386 1161910690 Reply Spam [+1] Moderate Up Moderate Down RemoveThis thread got on to an idiotic twist, but so far your lesbian theory makes more scense thatn the real explanation, so I am thinking of giving you the 2 million doloars for not being a dickhead, but let's see if the conversation can thread off into somthing that has nothing to do with the video (as it usdually does) and ends up with gay monkeys, or whatever. Fucking morons.
i remember in sixth grade or something a teacher talking about a metal that can be cooled enough to become magnetic.
By najohodo 1161907414 Reply Spam [+1] Moderate Up Moderate Down RemoveI have a good feeling you are right the addition of liquid nitrogen allows certain substances to become superconductors

then you're a language retard... there's such a thing as standard / formal english and then there's coloquial english.. and in case your vocab is not vast enough, that's localised / informal spoken language for everyday use. In some places using double negatives are perfectly accepted and understood. U just betrayed your ignorance, smart-ass.

By Captain Barefoot 1161833981 Reply Spam [+2] Moderate Up Moderate Down RemoveThe block is carbon graphite. Paramagnetic stuff. One can levitate a magnet with another beneath the block too at room temperature without liquid nitrogen; but the setup mst be solid and stable, and adjustable to get it right. Magnets rule.
By Kevin Scientist 1161815285 Reply Spam [+2] Moderate Up Moderate Down Removethe one on the top is a rare earth magnet and the one on the bottom is a high temperature superconductor, the liquid is nitrogen at 77° Kelvin or -195° Celcius, ( I don´t do imperial so ? on °F) it is called high temperatur because low temperature superconductors only work with liquid helium at 4° Kelvin, when it becomes a superconductor it repells magnetism so you get this effect.
By fenrisulfur 1161801156 Reply Spam [+2] Moderate Up Moderate Down RemoveIt's all obviously done with magnets. The substance poured onto the block thingy must have been something to make it repel the metal circle thing but the metal circle thing it attracted to it so when its picked up, they stay together. And then the chemical wears off. I'm only 13 so there's most likely something wrong with my logic ^_^
By SuperLamaCow 1161782440 Reply Spam [+2] Moderate Up Moderate Down RemoveWhen you have 2 ferromagnetic metals and you put one of them from normal temperature to -273 C which is 1 Kelvin Degree the moleculas of the metal move so fast they created fricction when this happens a magnetic field is also created.
Got nothing to do with Electro Magnetic Field, Electro Magnetic Field is the one we induce with electricity, like the big magnets on junk yards, the yoke is use to find cracks on metals prior to use as construcction materials, tanks inspection and so many other.
-273°C is 0°K not 1 :P

By _Shimon_ 1161786275 Reply Spam [+0] Moderate Up Moderate Down Remove1
the black part is a superconductor (some copper oxide). when it gets cooled down by liquid nitrogen it becomes superconducting. the magnet can induce circular currents inside the superconductor which makes it magnetic too. when it\'s temperature rises again the effect of superconduction vanishes again once it\'s above the critical temperature.
By fede23 1162290614 Reply Spam [+1] Moderate Up Moderate Down RemoveThis is just a low temperature superconductor with a standard magnet! One property of a superconductor is that it dissipates magnetic fields. That is why the magnetic needs to be pushed towards the superconductor once cold to trap it within the magnetic flux lines.

By avatarfan92 1161900737 Reply Spam [+1] Moderate Up Moderate Down Removethe black disc is a "Semi - Conductor" (one of a few types of semi - conductors).
in normal temperature the disc behaves as a semi - conductor, which produces a certain force against the magnetic field comming from below, BUT the repealiation force by the semi - conductor is not strong enough to push the disc away (it is not stronger than the force of gravity).
next stage - cool down the disc using liquid nitrogen, in this temperature the semi - conductor changes its features and become a "super - conductor". as a super - conductor the disc repealiation force is strong enough to push it self and overcome the gravity force.
and thats what happens.
Is this ? The bullet train rides on a magnet, does not touch the track, and goes over 120 mph. Cruise is so smooth, even at high speeds, because there is no traction, or friction, only the principles of magnetic force holding the train aboe the rail. Amercia could afford one if we didn't spend all our resources on wars that have nothing to do with us.
