This paper tries to deduce the time domain model of magnetic power loss without integral term from the basic magnetic induction, eddy loss, and supposed hysteresis loss equations. Based on the results of the50~5000Hz frequency domain and magnetic flux density of 0.1~1.8T, the overall average error rate is lower than 6%. It applies to both periodic and non-periodic magnetic field conditions. Based on the new instant loss equation in the changing magnetic field, the power loss of magnetic materials includes the induced eddy current loss. It is related to the instantaneous variation of the reciprocal of the magnetic permeability. It is found that the hysteresis loss is dependent on the saturation of magnetic field intensity.
