Induction and dielectric heating

Induction and dielectric heating have assumed in recent years an important position in industrial heating; dielectric heating more recently than induction. These unique forms of heating, once responsible only for power losses in electric equipment and machinery, offer many advantages over conventional means of heating by convection, conduction, and radiation. The field of application is very broad because induction heating is suited to metals, particularly those that have a high magnetic permeability, and dielectric heating may be accomplished in a large class of thermally insulating materials which at low frequencies are also electrically insulating.
