Abstract :
A method is presented for modeling two-dimensional dipoles, quadrupoles, and other higher multipoles built using oriented permanent-magnet materials such as samarium cobalt. The technique uses a complex current doublet to model the magnetized material. This technique can be used in conjunction with an infinitely permeable circular iron shield which lies outside the rare earth cobalt material. Examples of two types of dipoles and quadrupoles are discussed.
