“…This coupling model is chiefly suitable for the influence of stress on magnetic hysteresis loop. In a microscopic view, the domain variable model was put forward on basis of magnetic domain switching mechanism by Hwang [9][10][11][12][13] . The characteristic curves including stress-strain curve, electric hysteresis loop, and butterfly curve were simulated in the ferroelectric experiment.…”

The magnetic hysteresis loop is a significant performance of ferromagnetic material. The different-size specimens were fabricated and studied on the basis of magnetomechanical coupling tests. The curve of relationship between model size and magnetization intensity is obtained and hysteretic curve is described in the different conditions. The results indicate that the influencing law is reflected based on size effect of model specimens and performance of magnetic hysteresis and magnetization intensity. The results indicate that the size of Q235 steel model specimens is considerably influential in the magnetic hysteresis loop and magnetization, which accounts for an evident size effect.
