skin effect

skin effect
the phenomenon in which an alternating current tends to concentrate in the outer layer of a conductor, caused by the self-induction of the conductor and resulting in increased resistance.
[1895-1900]

      in electricity, the tendency of alternating high-frequency currents (electric current) to crowd toward the surface of a conducting material. This phenomenon restricts the current to a small part of the total cross-sectional area and so has the effect of increasing the resistance of the conductor. Because of the skin effect, induction heating can be localized at the surface and the heated area controlled by a suitable choice of the inductor coil (see induction heating). The skin effect becomes more pronounced as the frequency is increased.
