In this paper, dynamic formulation for energetic model proposed by H Hauser of ferromagnetic hysteresis is compared with the Jiles‐Atherton model that has been applied for hybrid magnetic field formulation. This model is based on the concept of the losses separation method. The energetic model is suitable for quasistatic ferromagnetic hysteresis and to improve this model in dynamic behavior, we modify the total energy given by the energetic model by introducing 2 additional energies associated with classical eddy and excess losses. Two new parameters related to eddy and excess losses are introduced. The identification of these parameters is achieved by measuring the volumetric energy density. All parameters are kept constant regardless of the used frequencies. The validity of this approach is justified by comparison of calculated hysteresis loops to measurements for different frequencies, and good agreements are obtained.
