Магнитное поле в тонкостенной листовой заготовке при низких значениях рабочих частот

Abstract

Characteristic of magnetic field excited in the metal of a thin-wall sheet billet in an inductor system at low values of operating frequencies of a current impulse is calculated. It is revealed that a high-power normal component of the magnetic field strength, distribution of which is not limited by the width of the induction coil, is excited.
