A ceramic is bathed in liquid nitrigen and becomes "superconducting. At this point, the electrical conductivity of the substance increases substantially. Since a current generates a magnetic field, the superconductor become an elecromagnet. The traditional magnent is suspended above the superconducting magnet with just the right balance of gravitational attraction and magnetic repulsion.
