Abstract

This paper presents an efficient implementation of the Fast Multipole Method for the computation of magnetic field and electromagnetic force. The total computational cost of our technique is proportional to O(N log N) , where N is the total number of discretization points in the system. Sample numerical results are presented for the vector potential, magnetic field, and magnetic forces in systems of solenoids interacting magnetically..
