Abstract
An electrically conductive material is heated by Joule heat generated by an eddy current loss and a hysteresis loss which are invited by a magnetic field injuced in the material by a current flowing in proximity to the material. The power output of the heating equipment is varied either electrically or mechanically while maintaining the inductance of the induction heating coil substantially constant.
