    A superconductor is a material that has zero electrical resistance at certain temperatures. For example, in a ring of superconducting material, if you induce a current to flow in a circle, it will continue flowing for ever. So far, it has only been possible to create superconductors at cryogenic (i. e., "supercold") temperatures.
