One of the important problems in the utilization of soft magnetic materials, like electric sheets, is the knowledge of the hysteresis loop and of the hysteresis losses. The determination of both, but more of the latter ones is sometimes difficult, especially their determination can be performed with certain deviation due to the used procedure. The aim of the present paper is to present a procedure simple enough and of a high accuracy for the mentioned determinations.
