MIT Physics lecture demonstration:
MAGNETIC FIELDS - Magnets
A 2 inch supercontucting disk is immersed in liquid introgen. A small, very strong magnet is placed on top of the superconductor. The magnet will levitate and can be moved around with plastic tweezers. This is displayed with the TV projection system.
