The article compares two magnetization models for magnetically soft amorphous alloys: the main magnetization curve using approximation functions in the form of an incomplete polynomial of odd degree and the Chan hysteresis model. The relative error of modeling is chosen as a criterion for the accuracy of the model. The purpose of the study is an objective assessment of models according to the criteria of simplicity and accuracy. In the study, the least squares method was used to simulate the main magnetization curve and the method of optimizing the Chan hysteresis loop using experimental and reference data. The final conclusion about the advantages of a particular model can be made only on the basis of the final goals of the analysis, since both hysteresis models have approximately the same errors equal to 5-9% in some areas.
