induction or by the relative motion of a conductor in a magnetic field. Eddy currents flow in closed loops within conductors, in planes perpendicular to the

retarder, is a device used to slow or stop a moving object by generating eddy currents and thus dissipating its kinetic energy as heat. Unlike friction brakes

conductive materials. Eddy current testing (ECT) as a technique for testing finds its roots in electromagnetism. Eddy currents were first observed by

manufacturers high-linearity, high-speed measurements, and high resolution. Eddy currents are formed when a moving or changing magnetic field intersects a conductor

non-ferrous metals from an input waste or ore stream. The device makes use of eddy currents to effect the separation. Non-ferrous metals typically separated by

field induces eddy currents in the workpiece. The frequency of the inductive current determines the depth that the induced eddy currents penetrate the

field. They have useful applications in eddy current brakes and induction heating systems. However eddy currents induced in the metal magnetic cores of

account. In alternating current (AC) devices they cause energy losses, called core losses, due to hysteresis and eddy currents in applications such as

side adjacent to the nearby conductor. Proximity effect is caused by eddy currents induced within a conductor by the time-varying magnetic field of the

eddy currents and thus dissipating its kinetic energy as heat. Eddy (film), a 2015 Italian film Eddy & The Soul Band, a 1980s Dutch disco group Eddy (Ed
