Abstract :
We present a Green´s function for a circular loop in a toroidal cavity in a high-permeability material. We show that under certain conditions, Green´s function may be expressed in terms of Jacobi´s theta functions. We demonstrate an application of such a Green´s function in analyzing the performance of pot core transformers. Results compare well with the values obtained by other analytical methods and by the measurement
