In electromagnetism, eddy currents (also called Foucault's currents) are loops of electric current induced within conductors by a changing magnetic field in the conductor according to Faraday's law of induction or by the relative motion of a conductor in a magnetic field. Eddy currents flow in closed loops … See more The term eddy current comes from analogous currents seen in water in fluid dynamics, causing localised areas of turbulence known as eddies giving rise to persistent vortices. Somewhat analogously, eddy … See more A magnet induces circular electric currents in a metal sheet moving through its magnetic field. See the diagram at right. It shows a metal sheet (C) moving to the right under a … See more Electromagnetic braking Eddy current brakes use the drag force created by eddy currents as a brake to slow or stop moving objects. Since there is no contact with a … See more • Eddy Current Separator Cogelme for non-ferrous metals separation – Information and video in Cogelme site See more The first person to observe eddy currents was François Arago (1786–1853), the 25th Prime Minister of France, who was also a mathematician, physicist and astronomer. In 1824 he observed what has been called rotatory magnetism, and that most conductive bodies … See more Eddy currents in conductors of non-zero resistivity generate heat as well as electromagnetic forces.
