Abstract :
A numerical method to obtain nonuniform field distribution in magnetic substrates is presented. The method is applicable to different geometries and it is not restricted to uniform applied fields. The only assumption is that the local internal field is high enough so the material is saturated and at all points the magnetization is parallel to the local internal field.
