Abstract - In this paper we present a benchmark problem for the validation of numerical models of vector magnetic hysteresis. The problem geometry and the measurement system are described. The materials considered are both oriented grain OG and not oriented grain NOG Si-Fe steels. A series of experimental data about magnetic field and magnetic induction loci under rotational magnetization are presented with the corresponding magnetic losses. The measured data can be useful as a reference for the numerical models testing, comparison and development. In addition, we propose here a comparison of the experimental data with the numerical results computed  using a vector hysteresis model based on the extension of the Preisach model in 2-d.
