Some Remarks on Hysteresis

Abstract

This paper considers two approaches by which the Preisach distribution function may be obtained from experimental hysteresis curves, and then compares the results of these approaches with Bate's experimental results. The first method, based upon the assumption that φ(a,b) = φ1(a)·φ2(b), was proposed by the authors in 1958. The second method is valid under other assumptions, and requires simple computations only. The comparison shows good agreement between the two methods, and with experimental data.
