This paper deals with the characterization of magnetic after effect in soft magnetic materials. A classical volt-amperometric technique is properly developed to reconstruct the behavior of magnetic ﬂux density B holding the magnetic ﬁeld H at ﬁxed value. The proposed methodology bases on the reconstruction of the B history starting (terminating) the B −H path from well known and stable initial (ﬁnal) conditions, such as the saturation region. Experimental results were performed under controlled climatic conditions on a commercial soft ferrite core.
