Abstract :
This paper presents an efficient implementation of the fast multipole method (FMM) for magnetic field and electromagnetic force computations. The total computational cost of our technique is proportional to O[(N+M)ln(N+M)], where N is the number of evaluation points and M is the number of source points of the system. This technique is based on the efficient computation of the integral in the Biot-Savart law by using the FMM technique. Sample numerical results are presented for the vector potential and magnetic field in a toroidal system
