An accurate and efficient static hysteresis model is proposed that phenomenologically describes hysteretic properties based on the asymmetric transition probability of magnetization. The transition probability function is determined from first-order reversal curves. The model provides magnetic hysteresis curves using a simple function calculation without any assembly of hysterons. A comparison with measured properties of silicon steel shows that this model represents hysteretic properties, including minor loops more accurately than the play-hysteron-based model.
