摘要：
The specification of the relation for irreversible relative permeability at initial magnetization curve is presented, using the linear functions approximation of DC energy losses for Fe-resin soft magnetic composites. The experimental and calculated dependencies of irreversible permeability vs. magnetic induction were compared, and the empirical function in this relation was determined to be a constant. The proposed relation allows to cover a wide induction range of validity of the linear function approximation (wider compared to the Steinmetz law for the special case of Fe-resin composites), with even higher accuracy than the previous relation derived from the Steinmetz law.
