Definitions for "Superconductivity"
The flow of electric current without resistance in certain metals and alloys at temperatures near absolute zero. Perpetual motion on an atomic scale; the conduction of electricity without the slightest power loss - perfect conductivity.
su pEr kan dEk tI vih ti] A property of many metals, alloys, and chemical compounds at temperatures near absolute zero, by which their electrical resistivity vanishes and magnetic fields are expelled.
The ability of some materials to maintain perpetual electric currents without heat or energy loss owing to the complete absence of electrical resistance.
