Abstract
A simple model used previously by the authors to explain stress variation of magnetic hysteresis is now employed to explain the effect of stress on the amplitudes of the first- and third-order harmonics of the magnetic induction signal resulting from application of an ac magnetic field of low frequency to a steel specimen. An improved expression for the effective field contribution Hσ due to stress has been derived from thermodynamic considerations.Keywords
