The worked layers of polished ferrites were estimated by electron-diffraction method and the principal mechanism of magnetic characteristic changes was clarified. Effective non-magnetic layer of abraded ferrites can be estimated by measuring reluctance of a toroidal core with worked layers perpendicular to magnetic path : the depth of the layer was obtained by
