An extended analysis of the sensorless measurement methods adoptedfor the characterization ofsoft magnetic materials is here reported. The capability ofmeasuring non symmetric cycles and their accommodation is reported together to a discussion on the main critical aspects and limits of the presented techniques. Key question is if the capabilities of the sensorless method have been fully explored or if such a technique can be extended to the measurement of other phenomena related to the magnetic hysteresis, as the after-effect, as well as adopted for the reconstruction of hysteresis losses associated with open loops.
