WebAn inductor is a current filtering device. By resisting change in current, the filter inductor essentially accumulates stored energy as an AC current crests each cycle, and releases that energy as it minimizes. Power inductors require the presence of an air gap within the core structure. The purpose of the gap is to store the energy, and to ... WebIn electromagnetics, proximity effect is a redistribution of electric current occurring in nearby parallel electrical conductors carrying alternating current flowing in the same direction which causes the current distribution in the conductor to concentrate on the side away from the nearby conductor. It is caused by eddy currents induced by the time-varying magnetic …
