ともより容易となる。Also, in the case of a structure in which a non-magnetic high electrical resistance material such as ceramics is wrapped around an amorphous ferromagnetic ribbon, and the conductor is passed through the center of the ribbon, it is easy to insulate the amorphous wire from the conductor, and heat treatment is performed with the winding removed. It is preferable because it is easy. Further, in this case, it becomes easier to wind the amorphous material in a toroidal shape.
