ABSTRACT:
A method of annealing a core comprises the following steps. First annealing coils are wound around the legs or yokes of a core or parallel-arranged cores made of an amorphous magnetic alloy. Secondly, the core is excited by flowing an alternating current through the annealing coils. Thirdly, the core interior is uniformly heated to an annealing temperature of amorphous magnetic alloy plates by heat generated due to iron loss.
