    Dear community,

    Today I stubbled upon this movie: http://www.youtube.com/watch?v=c3asSdngzLs
    Can anyone tell me what is happening right here? The little black block seems to become magnetic in a very stable way? I've never seen anything like this. It's like beem me up scotty...lol

    Superconductor

    There's yer answer.

    If it was anti gravity it would be repelled away and it isn't. The super cool liquid nitrogen creates a state of temperature for that black peice of metal which allows the amazingly almost flawless passage of electrons through it so the repulsion is super great, and as wolf said, superconducting.

    I had that idea in school-to put a load of magents in a box shape and watch the funny peice of metal in the middle XD, little did I know that it was this cool.

    On a more seroius note there seems to be a natural balance to the repulsion of the metal to gravity, even if either one was more or less massive. This is very curious indeed. Perhaps because Entropy has a great deal to do with thermodynamics that time-hence space are linked to it, hence gravity. Just an idea...

    The black block is a superconductor. The metal disc is a magnet.

    Liquid nitrogen cools the superconductor to a temperature where it becomes superconducting. When the magnet gets close to it, its magnetic field creates an electric current in the superconductor, which in turn generates a magnetic field of the same intensity as that of the magnet but with its polarity inverted -the magnet's north pole generates a north pole in the closest surface of the superconductor, and thus the magnet is repelled by the combined force of its own magnetic field and the reflex magnetic field generated at the superconductor. This causes the magnet to hover; any attempt to move it closer will increase the repulsion and it will return to the point of balance.

    There is no evidence of anti gravity. There also isn't any artificial gravity (despite the use of the term by some). Conditions can sometimes be simulated to either mimic or counter the impact of gravity.

    Yeah they use this in the japanese train system lol (think of it as hover-trains)

    Did you notice the super conductor lift up at the end. Create a blast over a super conductor and watch what happens.

    It is fun to see, but not very practical. Very dangerous.
