A Brief Review on Induction heating
Abstract: Induction heating is the method of heating an electrically conducting material (usually a metal) by electromagnetic induction, through eddy currents generating heat in the object. An induction heater is an electromagnet and an electronic oscillator that passes through the electromagnet through a high-frequency alternating current (AC). The rapidly alternating magnetic field penetrates the artifact, producing the conductor's electrical currents called eddy currents. The eddy currents flow through Joule heating through …
