A ferromagnetic toroidal core of iron powder was studied experimentally and numerically. Hysteresis loops, major and several minor ones were detected and measured with the help of a special setup. A genetic-type algorithm was developed and used to fit parameters of a model of ferromagnetic hysteresis. Experiment and theory supported by numerical modelling lead to a proper description and deep understanding of complicated processes that take place in the studied magnetic material.
