Summary

Meissner effect using a high-temperature superconductor and powerful Rare-earth magnet.

"In the late 1980s, Pacific Northwest National Laboratory researchers conducted research into superconductors. The ceramic superconductors are made from a material that has only very low alternating-current resistance and thus dissipates less power. Magnetic forces between the magnet and ceramic superconductor provide a magnetic cushion that keeps the magnet suspended above the superconductor. Liquid nitrogen cools the superconductor to about 77 Kelvin, producing the magnetic cushion." From the Pacific Northwest National Lab. March 1987.
