MIT Physics Demo -- Levitating Magnet

A magnet with a very strong magnetic field is held in place on an aluminum disk. The disk is attached to a motor powered by variable AC current. When the disk rotates, the magnet will levitate above it due to eddy currents generated in the disk. With the disk spinning, these eddy currents form to oppose the magnetic field of the magnet, making it levitate. When the motor is turned off, the magnet falls back to the disk.
