Superconductivity is a quantum mechanical phenomenon where a material exhibits zero electrical resistance and expulsion of magnetic fields below a critical temperature. This allows for highly efficient energy transmission and powerful magnetic applications, but practical use is limited by the need for extremely low temperatures or high pressures.

quantum mechanical phenomenon

Zero electrical resistance is a phenomenon where electrical current flows without any energy loss, typically observed in superconductors below a certain critical temperature. This property allows for highly efficient power transmission and the creation of powerful magnetic fields without the heat generation associated with conventional conductors.

Critical temperature is the highest temperature at which a substance can exist as a liquid, regardless of pressure, marking the end of the liquid-gas phase boundary. Above this temperature, the substance becomes a supercritical fluid, exhibiting unique properties that are distinct from typical liquid or gas states.
