MAGNETOSTATIC ENERGY CALCULATIONS IN 2-DIMENSIONAL AND 3-DIMENSIONAL ARRAYS OF FERROMAGNETIC PRISMS

Exact analytic expressions for magnetostatic energy calculations in ar rays of ferromagnetic prisms are presented. They apply to two-dimensio nal (2-D) and three-dimensional (3-D) arrays of variable length prisms with uniform magnetization inside each prism. This permits the study of irregular magnetic structures allowing also a variable grid where t he size of the cells depends on the structure itself. These expression s cover all possible cases for 2-D and 3-D problems.
