The Meissner effect shown by levitating a magnet over a cuprate superconductor, and that is cooled by liquid nitrogen Below some conditions, which include really reduced temperatures, some ceramics show high-temperature superconductivity (in superconductivity, "high temperature" implies above 30 K). The reason for this is simply not understood, but
