Original Abstract

. The Jiles-Atherton model of a hysteresis loop enables us to capture the behaviour of a magnetic material at the level of domains. At present, the model finds a large number of applications, for example in Spice simulators, where it facilitates the description of the behaviour of a core made from a magnetic material. The paper contains a discussion of constraints related to the original algorithm for the calculation of the model parameters and presents the results obtained via the least-squares method. Based on the measured typical behaviour of hysteresis loops (rounded and flat), we calculated the error between the measured and the calculated loops. To facilitate better approximation of the measured loop, the original computation model was modified, and the acquired results are presented within this article.
