"WebEddy currents flow in circular loops within the conductor itself, in the direction perpendicular to the magnetic field. According to Lenz’s Law, the induced eddy currents generate another magnetic field so as to counter the actual magnetic field. This action resists the actual current flow in the conductor resulting in power loss in the form of heat. " - Eddy currents wikipedia
