Determining the factors influencing the reproducibility of measurements in the asymmetric cycle «coercive return—magnetization»

The induction of coercive return and induction of coercive force inversion can be used for magnetic structure analysis. On the example of the problem of heat treatment testing of 20H2M steel, the influence of the remagnetization rate and the resolving power of the current source on the magnitude and character of the obtained dependences is shown. It is established that a high rate of remagnetization and a large step of current setting are interfering factors complicating the reproduction of measurement results and obtaining reliable dependences.
