supraleittava
Supraleittava is Finnish for superconducting or superconductivity. In physics, superconductivity is a quantum phenomenon in which a material conducts electricity with zero direct-current resistance and often expels magnetic fields when cooled below a characteristic critical temperature. The term is widely used in Finnish-language texts to describe materials, devices, and effects related to this phenomenon.
Key properties of supraleittava materials include zero electrical resistance at and below the critical temperature (Tc),
Mechanisms and classes: Conventional, or low-temperature, superconductors are explained by BCS theory, which describes Cooper pairing
Materials: Early examples include elemental mercury, which Onnes showed would superconduct at 4.2 K. Modern applications
Applications and impact: Supraleittavat materials enable MRI machines, magnetic levitation transport, and superconducting magnets for particle
