Eddy Current Testing

An eddy current is a circulating electric current induced within the body of a conductor when that conductor either moves through a nonuniform magnetic field or is in a region where there is a change in the magnetic flux. Typical currents of this sort resemble in form the eddies in flowing streams of turbulent water, hence, the name eddy currents.
