    The plastic deformation of a electrical steel results in increase of the dislocation density in the material lattice. It leads to an increase of the number of pinning sites for the magnetic domain wall motion and a general deterioration of the magnetic properties. However, another side effect of the plastic deformation is the residual stress. In this paper, an approach is proposed allowing evaluation of the anisotropy of residual stresses by means of the local magnetic measurements. A good correspondence of the obtained results with X-ray measurements was encountered.
