Электрофизические особенности возбуждения импульсного напряжения и индукционного тока в металлических элементах технических объектов различной толщины и электропроводности

Abstract

The results of approximate solution of electrophysical problem concerned with determination of time shift between exiting (primary) unipolar current pulse of inductor and induced (secondary) pulsed current of metallic work piece treated by magnetic field of the inductor are presented. It’s shown that this current shift depends significantly on front duration of exciting unipolar pulse of inductor current and frequency spectrum of this pulse.
