Abstract :
The profiles of the second-order harmonics during B-H hysteresis loop have been measured as functions of the tensile stress and the angle φ between H-field and [001] axis in 3% silicon steel. The observed harmonics profiles have been analyzed in terms of the nonlinear, asymmetric magnetic induction which reflects the domain reorientation under the field. The field interval of the second harmonics is related to the nucleation and annihilation fields and a measurement method for the magnetostriction is proposed using the harmonics profiles under tensile stress
