Abstract :
A program for calculating static magnetic fields using an integral method for the iron contribution to the field is presented. To calculate the magnetic coefficients one essentially uses a simple dipole approximation. The developed formalism is applied to compute the magnetic field of toroidally shaped iron geometries. Using this formalism a program tractable on microcomputers was written with a discretization of the iron in up to 1600 elements. The results agree well with those obtained with the program TOSCA
