Abstract：
 The present invention relates to an embedded permanent magnetic bias ferromagnetic conductor which is a novel component applied to the fields of the electrician technology and the electric power equipment. The present invention comprises two quadrate cross-sectional magnetic conductors that are made of common ferromagnetic materials, two or more permanent magnets, and one or a plurality of coils; wherein, the two quadrate cross-sectional magnetic conductors made of common ferromagnetic materials are isolated in the middle, and the upper end and the lower end are provided with a permanent magnet respectively. The four parts are connected from the beginning to the end to form a frame-type iron core, a placket-type iron core or a ring-shaped iron core; the polarities of the permanent magnets are opposite from the left to the right; the coils in series wind the whole ferromagnetic conductor. The present invention gets applied to difference electrical appliances; and can save materials, reduce the active loss and the reactive loss, simplify the structure, increase reliability; and is of great technical and economic significance.
