Can Anyone Explain This???

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).

you shouldnt be showing that because the government is using that technology in their Flying disks... no joke. they might get angry that you know how it works... you should try and get a mini disk flying!! it will work if you kow how to do it!! this world is coming to an end!! A new world order is emerging

actually a plastic look a-like magnet that is on a transparent string held by the puppet master himself.

The 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.

the 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.

It'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 ^_^

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.

This 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.

David Blaine was the one doing the magic on this video

this must be the first post i've seen where no one has said 'its fake'.

Have always loved magic. Levitation, flight, hearing someone talking hundreds of miles away, riding steel chariots that can zoom at 75mph... Science is magic that actually works.

look at the left bottom of the floating magnet and there is a yellow dot. its at 59 seconds into the vid

the 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.

The Earth is suspended in the vacuum of space.. nothing on top, nothing on bottom yet it FLOATS in space! All that weight!

This video is showing an example of a Superconductor. More information regarding what a superconductor is can be found at http://www.superconductors.org/INdex.htm.

thats pretty lame its a magnet you cool the condutor on the bottom witch creates a mgnetic field and hold the magnet in place go take to magnets they go together then turn them around and they wont go together see haha stupid!

magnetic feilds....

the comment yo got about the english language made me laugh but how it works is got me

carbonic ice and a magnet.

drink my balz

is holding it!!

Though it looked a little fake.

Stick your finger in the liquid nitrogen! ;P

was super duper cool

simple......... se invierten los polos......
al enfriarlo a temperaturas muy bajas..........

It is pretty obvious what is happening. The round thing is like...hovering about the other thing. Duh!

There's formal / standard English, and then there's colloquial English. And in case your vocab is too limited to know what it is: it's informal / localized / everyday-use English. In some parts of the world double -ve expressions like "dunno nuthin" is perfectly understood and accepted. You just betrayed your own ignorance, smart-ass.

old delete it already

He passed away to this world in 1994 , but his vision still lives on. Tin Boo Yee was a great rocket scientist. Hope his work get reknown to the world.

Is that science or magic
=D

keep 'em coming, Josephine may be able to help with that one!

this is just a simple procedure where this guy made a hight temperature superconductor by using liquid nitrogen.
you'll see it alot in college :)

wow.what is that??how??

lagging like hell, couldnt see a thing

I read about this in my science book...the black thing is a magnet...the liquid is liquid hydrogen and the silver thing is what the call super cunductable material,i don't know the real name but...google it ...you might get more information than a 14 year old...lol

old news

it seem that he create a magnetic field. nice one thankx
