The article discusses a novel procedure for measuring the anhysteretic curve in soft magnetic materials. This curve frequently finds use in diverse applications, such as the Jiles-Atherton hysteresis model. The actual method is characterized in detail, including sample calculations for materials exhibiting various hysteresis loop shapes (ferrites, grain-oriented steel, and nanocrystalline material). To illustrate the benefits of the proposed approach, the authors compare the measurement-based and the simulated curves, the latter being obtained through an optimal interleaving of the model.
