perspectives of superconductivity implementation

Point of view Superconductivity is a phenomenon where a conductor, once cooled beneath a certain heat, loses every electrical level of resistance and ejects any magnetic fields inside itself. When ever this state of superconductivity is obtained, the director will be able to transfer electrical energy with no loss in ...
