- noun an electric current induced in the iron core of an electromagnet by an alternating magnetic field, frequently a source of wasted energy
- A circulating current induced in a conductor that is moved through a magnetic field, or which is subjected to a varying magnetic field. Eddy currents are generally undesired, and energy is lost usually in the form of heat. Laminations may be used in magnetic cores to minimize such losses of energy. Also called Foucault current.
