eddy current, in electricity, motion of electric charge induced entirely within a conducting material by a varying electric or magnetic field or by electromagnetic waves. Eddy currents induced in a power transformer core represent lost power and are undesirable; eddy currents used to produce heat for cooking or for a metallurgical furnace represent useful applications of the phenomenon.
