PROBLEM TO BE SOLVED: To provide an electromagnetic body, which is formed of material of integral structure of conductor and ferromagnetic body and equipped with a function of effectively accumulating magnetism generated from electricity, so as to reduce electricity loss induced, when electricity is turned to magnetism. SOLUTION: A ferromagnetic body 2 is provided to a conductor 1 in the lengthwise direction of its outer circumference, through the intermediary of an insulator 3 excellent in permeability in the lengthwise direction of the outer circumference of the conductor 1, and furthermore, another insulator 3A excellent in permeability is provided to the outer circumference of the ferromagnetic body 2 for the formation of an electromagnetic body. Power loss can be reduced to an irreducible minimum by the use of the electromagnetic body. |
