Calculation of the Main Magnetization Curve of Structural Steels Based on Parameter Measurements of the Limit Hysteresis Loop

A formula has been derived for calculating the main magnetization curve of steels from the strength of the magnetizing field and the measurement results of the magnetization of technical saturation, coercive force, and residual magnetization. We analyzed the influence of material magnetic properties on the approximation of its magnetization to technical saturation.
