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

Abstract

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 <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">\vec{B}</tex> and the magnetic field strength <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">\vec{H}</tex> 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.
