Abstract

PURPOSE:To control magnetic saturation characteristic, by crystallizing a part of an amorphous magnetic core to provide the same effect as one with a magnetic clearance deteriorated in magnetic characteristic. CONSTITUTION:A wound iron core 1 constituted in winding an amorphous magnetic thin band is provided with a crystallized part 2 on a part of this wound iron core 1. This crystallized part 2 is obtained by contacting a heating head on the outer surface of the wound iron core 1 for heating for a long time at temperature over or less than crystallizing temperature. The range of the crystallized part and degree of crystallization arbitrarily control magnetic saturation characteristic so as to contrive the application for various oil parts.
