The Meissner Outcome shown by levitating a magnet over a cuprate superconductor, which can be cooled by liquid nitrogen Below some circumstances, like extremely reduced temperatures, some ceramics exhibit high-temperature superconductivity (in superconductivity, "high temperature" signifies previously mentioned thirty K). The explanation for this isn't understood, but There are 2 https://silica-magnetic-beads48146.tblogz.com/details-fiction-and-aln-thermal-conductivity-52356247
