Faraday Induction Consider a single turn of wire, through which an externally-applied magnetic flux is present. The flux varies with time. A current, Iind , is generated in the wire loop as a result of the changing magnetic flux.

Replacing Current with Electric Field Current in the wire is caused by electric field, E, that pushes the charge around the wire. In this illustration, the wire is removed, and the electric field remains. An integration contour, C, is also shown, that coincides with E.
