It is shown that the analytical theory of hysteresis, which determines the value of J at the end of an arbitrary path of H if the magnetization curve and the saturation loop are known, can be extended to compute the energy losses due to hysteresis along an arbitrary transformation, open or closed, in the (J, H) plane. The theoretical data have been computed for a soft iron specimen and for an Alnico type material. The latter have been compared with experimental data taken by Bates and Simpson on a similar material. The quantitative agreement between theoretical and experimental curves is quite satisfactory.Si la courbe d'aimantation et le cycle à saturation sont connus, on démontre que la théorie analytique de l'hystérésis, qui détermine la...
