The Meissner Effect shown by levitating a magnet earlier mentioned a cuprate superconductor, and that is cooled by liquid nitrogen Beneath some problems, including very low temperatures, some ceramics show high-temperature superconductivity (in superconductivity, "high temperature" signifies over thirty K). The rationale for this isn't recognized, but There are 2 https://isolation-of-trace-rna71582.wikilinksnews.com/6664587/top_latest_five_ceramic_alumina_urban_news
