Materialien, deren elektrischer Widerstand beim Unterschreiten der sogenannten Sprungtemperatur auf null fällt

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.
