Sign in to savethumb|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.
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.

Nadprzewodnictwo – stan materiału polegający na zerowej rezystancji, jest osiągany w niektórych materiałach w niskiej temperaturze. Nadprzewodnictwo zostało wykryte w 1911 przez Kamerlingha Onnesa. Jest to zjawisko kwantowe, niemożliwe do wyjaśnienia na gruncie fizyki klasycznej. Poza zerową rezystancją inną ważną cechą nadprzewodników jest wypychanie ze swej objętości pola magnetycznego (efekt Meissnera). Nadprzewodnictwo jest obserwowane w różnorodnych materiałach: niektórych pierwiastkach (na przykład w cynie, rtęci i ołowiu), stopach, ceramikach tlenkowych czy materiałach organicznych.
