The Meissner influence shown by levitating a magnet higher than a cuprate superconductor, that is cooled by liquid nitrogen Below some problems, for instance exceptionally minimal temperatures, some ceramics show high-temperature superconductivity (in superconductivity, "high temperature" means previously mentioned thirty K). The reason for this is simply not comprehended, but https://cesaryvndr.ageeksblog.com/37735566/the-5-second-trick-for-ceramics-material
