ABSTRACT:
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.
