Eddy current

Eddy currents (an aa cried Foucault currents[1]) are luips o electrical current induced within conductors bi a chyngin magnetic field in the conductor, due tae Faraday's law o induction. Eddy currents flow in closed luips within conductors, in planes perpendicular tae the magnetic field. Thay can be induced within nearby stationary conductors bi a time-varyin magnetic field creatit bi an AC electromagnet or transformer, for example, or bi relative motion atween a magnet an a nearbi conductor. The magnitude o the current in a gien luip is proportional tae the strenth o the magnetic field, the aurie o the luip, an the rate o chynge o flux, an inversely proportional tae the reseestivity o the material.
