ABSTRACT:
An electromagnetic induction device which comprises a split-type core assembly comprising at least one winding formed thereon and first and second core segments each having at least two joint faces spaced apart from each other, the first and second core segments are connected together with the joint faces of one of the first and second core segments held in contact with the joint faces of the other of the first and second core segments, and a finely divided ferromagnetic material is interposed between the joint faces of the respective first and second core segments. The ferromagnetic material used has an average particle size sufficient to form a magnetic fluid medium.
