Abstract

The demagnetizing current I dc is measured in different areas of an electromagnet-article magnetic circuit at the moment of zero crossing of the magnetic flux as the gap between the electromagnet and article changes. The weaker dependence of the I dce magnitude measured in close proximity to the article on the gap width and the possibility of using the parameter in measuring the coercive force of the article with an attachable transducer (in particular, with a Hall sensor) are demonstrated.
