A method for solving problems of electromagnetic field diffusion, in axisymmetric configurations with linear conducting media, is presented. The approach, which is based on lumped circuit modeling, has a number of theoretical and practical advantages in comparison with other methods currently used, particularly in dealing with problems where the coupling between the magnet system and the external feeding network is an important issue. The paper describes in detail the analytical basis and the numerical approach of the method and presents its most interesting aspects together with a discussion on a number of critical problems faced during numerical implementation. In order to show the method capabilities and performance some numerical results are also given.

Abstract
A method for solving problems of electromagnetic field diffusion, in axisymmetric configurations with linear conducting media, is presented. The approach, which is based on lumped circuit modeling, has a number of theoretical and practical advantages in comparison with other methods currently used, particularly in dealing with problems where the coupling between the magnet system and the external feeding network is an important issue. The paper describes in detail the analytical basis and the numerical approach of the method and presents its most interesting aspects together with a discussion on a number of critical problems faced during numerical implementation. In order to show the method capabilities and performance some numerical results are also given.
