An analysis of the possibility of measuring the remanent magnetization of a ferromagnetic material in an open magnetic circuit

Maximum magnetic permeability of magnetically hard steel and the limiting hysteresis loop

“…Measurements of the maximum magnetic permeability and residual magne tization in an open magnetic system do not corre spond to the values for the material in the samples, as shown in [14,15]. However, the measurements from [12] have been included in handbooks as the magnetic properties of the materials (for example, in [7, Fig.…”

“…Only results for H C and M S and the relaxational magnetiza tion M Hr of this steel may be found in the handbook [2, Table 49.2]. We may determine M R from M S and M Hr on the basis of the formula [14] M R ≈ M S (0.92 -2.55M Hr /M S ),…”
