This paper presents a method for calculating eddy current loss in the magnetic powder core based on electric and magnetic networks. First, an electric and magnetic model of single particle of magnetic powder core to calculate intra-particle eddy current loss generated in each particle of the magnetic powder is discussed. Then, eddy current losses of toroidal cores made from three sizes of magnetic powders are determined. Experimental results demonstrate the validity of the proposed method
