eddy current

an electric current in a conducting material that results from induction by a moving or varying magnetic field.
[1590-1600, for an earlier sense]

* * *

      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.
