フエライトコアを用いた環状磁気回路の一部に空
隙を設け、加熱用誘導電流を流す導体を環状磁気
回路に巻回してワークコイルを形成し、フエライ
トコアを用いた磁気回路の空隙部分に被誘導加熱
体を置き、加熱する様構成した誘導加熱装置。 A work coil is formed by providing a gap in a part of an annular magnetic circuit using a ferrite core with high effective magnetic permeability and material specific resistance at high frequencies, and winding a conductor through which a heating induction current flows around the annular magnetic circuit. An induction heating device configured to heat an object to be heated by placing it in the gap of a magnetic circuit using a ferrite core.
