superconduttività

thumb|A high-temperature superconductor levitating above a magnet. A persistent electric current flows on the surface of the superconductor, acting to exclude the magnetic field of the magnet (Meissner effect). This current effectively forms an electromagnet that repels the magnet.

AI overview

Superconductivity is a special state of certain materials where electric current can flow indefinitely without any resistance, and the material actively pushes away magnetic fields—an effect called the Meissner effect. This matters because it enables remarkable applications like magnetic levitation, where a superconductor can float above a magnet due to the repulsive force created by the persistent current flowing across its surface.

In fisica la superconduttività è un fenomeno fisico che comporta resistenza elettrica nulla ed espulsione del campo magnetico. Essa avviene in alcuni materiali al di sotto di una caratteristica temperatura detta critica, e semplificando, al di sotto di un caratteristico valore critico del campo magnetico. Come il ferromagnetismo e le linee spettrali atomiche, questo fenomeno non è spiegabile mediante la fisica classica, ma è necessario basarla sulla più complessa meccanica quantistica.
