Abstract

The paper reports on a calculation of coercive forces in two-layered toroidal samples composed of rings with various magnetic hardness on the base of magnetic hysteresis loops characterizing materials of each component. Secondary spectra of magnetic hardness of two-layered samples, characterizing distributions of critical fields in the process of cyclic magnetization, have been investigated. A suggested method for estimating the fractions of harder and softer components in composite samples uses the secondary spectra of magnetic hardness.
