{{#category_index:E|eddy current}} (ed’ ē) A circulating electrical current induced in a conductive body by a time-varying magnetic field. Lenz’s law states that the direction of eddy current flow is such as to produce a secondary magnetic field that opposes the primary field. The secondary field has a quadrature component that depends on the ratio of the resistance to the reactance of the eddy-current path. In electromagnetic prospecting, eddy currents should be distinguished from naturally occurring currents or those of natural electrochemical origin.
