Abstract
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.
