In the design of electric devices, it is important to know the relation between the magnetic properties of the materi- als and those of the core. This paper describes the magnetic properties of a composite tape-wound ring core with ac excitation. In the analysis, the magnetization characteris- tics are approximated by a Fourier series, and it is assumed that the eddy current factor is proportional to the rate of change of the flux. The results obtained by through this analysis are used to show the effect of the inhomogeneity of the magnetic properties of the material on the magnetic properties of the core. The results of the analysis were confirmed by the experiments.
