The Meissner effect demonstrated by levitating a magnet previously mentioned a cuprate superconductor, and that is cooled by liquid nitrogen Underneath some ailments, for example really small temperatures, some ceramics exhibit high-temperature superconductivity (in superconductivity, "high temperature" implies above 30 K). The rationale for this isn't comprehended, but There are https://silica-coated-magnetic-be37913.wizzardsblog.com/39187837/examine-this-report-on-what-is-ceramica
