The Meissner Effect shown by levitating a magnet previously mentioned a cuprate superconductor, which can be cooled by liquid nitrogen Below some circumstances, like extremely small temperatures, some ceramics show high-temperature superconductivity (in superconductivity, "high temperature" implies above thirty K). The explanation for this is not recognized, but There are https://andyeqajq.wikilima.com/1931819/the_best_side_of_advanced_ceramics_products
