Supercurrent

A supercurrent is a superconducting current, that is, electric current which flows without dissipation in a superconductor.^[1][2][3] Under certain conditions, an electric current can also flow without dissipation in microscopically small non-superconducting metals. However, currents in such perfect conductors are not called supercurrents, but persistent currents.
