In this paper the behavior of core loss coefficients is studied using a new method of core loss separation. This method eliminates the assumption of uniform magnetic field distribution in a material especiall y at high frequencies. With this separation method, the h y steresis and edd y current coefficients are calculated using the original Steinmetz equation and its derivative. The calculated loss from the coefficients of the two formulas is then compared to the loss from the separation. Results and conclusions are also presented.
