Abstract

We have calculated the Polder permeability tensor of a composite consisting of cubic arrays of magnetic spherical particles. Magnetic potentials associated with particle-particle interactions have been expressed in terms of multipole fields. The permeability tensor can be then expanded in power series of the particle volume loading. These results are in agreement with other method of calculation involving the free energy of a particle composite.
