The following paper presents the results of investigation on the magnetoelastic Villari effect in structural steel magnetized in the so-called Rayleigh region, which corresponds to relatively low magnetizing fields, much lower than coercive field. Two grades of structural steel were investigated during the performed measurements. Obtained results indicate significant correlation between applied mechanical stress and magnetic properties of the investigated materials.
