Abstract

Taking as examples toroidal model samples with equal values of porosity, but with pores of different shapes, we studied the effect of porosity, pore shapes, and applied magnetic field on the internal demagnetization factor for porous magnetic materials. An empirical formula has been obtained for estimating the internal demagnetization factor of porous magnetics.
