Abstract

In this paper it is presented a study of the magnetic anisotropy of non-oriented and grain oriented Fe-Si strips with the surface area of 280 x 30 mm2. The measurements were performed with a unidirectional single strip tester on Fe-Si strips cut at angles of 0, 15, 30, 45, 60, 75, 90 with the rolling direction. For the representation of the magnetic field strength at constant magnetic flux density it was used a program that interpolated the experimental results. It was determined the hard and the easy axis of the materials and the influence of the frequency on the anisotropy of the materials.
