Levitation of a magnet over a flat type II superconductor.
01 January 1988
Levitation of a magnet over a type II superconductor where the field at the superconductor exceeds H sub (c1) is described and shown. The penetration and pinning of the flux lines in the superconductor cause the position of the magnet to be stable over a flat disk; a complete Meissner effect would make this position unstable.
