FEATURES OF THE REMANENT INDUCTION DISTRIBUTION IN A 2-LAYER FERROMAGNETIC CYLINDER

Model specimens were used to study the distinctive features of the rem anent induction distribution in a two-layer steel cylinders with diffe rent ratios of magnetic properties and size of the surface layer and t he core after magnetization to saturation. The presence of a magnetica lly soft surface layer-leads to an abrupt drop in the total remanence in the central section of the cylinder without any change in the parab olic flux distribution along the cylinder. The effects detected are sh own to be due to magnetic reversal in the magnetically soft regions of the cylinder by magnetically hard regions in the remanent state.
