The paper presents a theoretical and experimental study of the behaviour of a FeSi80% magnetic alloy excited by a full rectified current. The experimental bench is described and the measured curve, called ΔB dynamic curve, is analysed using the dynamic Preisach model. A model including local and global dynamic effects is developed and a very close agreement with experimental data is found.
