L. Han et al., INTEGRAL-EQUATION METHOD USING TOTAL SCALAR POTENTIAL FOR THE SIMULATION OF LINEAR OR NONLINEAR 3D MAGNETOSTATIC FIELD WITH OPEN BOUNDARY, IEEE transactions on magnetics, 30(5), 1994, pp. 2897-2900
A method of simulating both linear and nonlinear 3D magnetostatic fiel
d with open boundary is described. It is based on the integration with
total scalar potential on the surface (linear problems) or in the vol
ume (nonlinear problems) of magnetic materials. For nonlinear problems
, this procedure can avoid the cancellation errors and is convenient b
ecause of the use of total scalar potential and the volume integration
only. It was tested by a given example and was applied to a deflectio
n field calculation of multipole yoke.
