Induction heating is the process of heating an electrically conducting object (usually a metal) by electromagnetic induction, through heat generated in the object by eddy currents. An induction heater consists of induction power supply (induction heater) and inductor (coil) that is a shaped to contour the part, and a work station where the part is held and presented to the coil.
