Magnetostrictive effect is connected with changes of the dimension of soft magnetic materials during the process of theirs magnetization. The paper presents newly developed measuring systems for testing of the strain distribution in the magnetostrictive materials. The system uses simultaneously two measurement techniques: strain-gauge sensor for local strain measurement and grating interferometry for the global determination of strain distribution.
