ABSTRACT:
An iron core for induction apparatuses is constructed of at least one main leg and yokes including side yokes comprising laminations of magnetic material. The magnetostriction of the yokes is smaller than that of the main legs, so that the vibration of the inductors is easily suppressed without any special means. Noise, which otherwise might arise from the vibration is thus reduced sharply.
