Improved method for the investigation of the rotational magnetization process in electrical steel sheets

The magnetization processes in electrical steel sheets in rotating and alternating magnetic fields up to 1.8 T can be investigated with an instrument which is described in this paper. The components of the vectors of the magnetic induction
\vec{B}
and the magnetic field strength
\vec{H}
are measured wlth four sensors during one period and processed by a transient recorder and a computer. Some results for rotating fields are presented for a sample of non-oriented silicon steel.
