DEMAGNETIZING EFFECT OF A DISPERSED MEDIUM

Factors of the demagnetizing effect of a dispersed medium (DM) with a filling coefficient K-upsilon > 0.4 are considered. It is shown that t he saturation magnetization J(sc) of the DM does not exceed the value K-upsilon x J(sf), where J(sf) is the saturation magnetization of the particle substance, and the DM demagnetization coefficient N-c is vari able and dependent on the magnetic permeance K-mf of the particle subs tance and K-mc of the DM, K-mc decreasing as K-mf increases.
