Magnetic properties of grain-oriented magnetic steel sheets under temperature distribution

Abstract Magnetic properties of magnetic steels were examined under temperature distribution in a single sheet. No magnetostriction change was observed at 23°C and 50°C under uniform temperature distribution. Peak–peak magnetostriction under temperature difference of 10°C was 6.0×10 −6 in the center of the sample at 1.5 T that was three times larger than that under uniform temperature.
