A magnetic field heating device for heating metal including a means to create an alternating magnetic field passing this magnetic field through a dissimilar metal part to uniformly heat the part. This differs from induction heating of metal parts because the part is heated uniformly rather than being restricted to the skin or outside portions of the part. This unique heating is accomplished by utilizing a novel magnetic loop for creating a high density alternating magnetic field in the metal part to be heated.

A device for heating metal comprising a magnetic loop open at two facing ends with an open space therebetween; said magnetic loop comprising a plurality of parallel thin plates of high magnetic permeability conductive material; said platen closely spaced and insulated from each other; a plurality of core areas, each of said core areas adjacent each of said facing ends and comprising a second plurality of parallel thin plates of high magnetic permeability conductive material having a face at right angles to the plane of the plates larger in area than the area of the facing end of said loop; and, a plurality of windings formed of conductive wires, each of said windings wound around each of said core areas adjacent said facing ends and connected to an alternating current source to reverse the magnetic field in said loop at the frequency of the alternating current source.
