Abstract

The quasi-magnetostatic solution for a conducting and permeable spheroid under the excitation of a uniform time-harmonic field is obtained using vector spheroidal wave expansions. The direction of the primary field is arbitrary. The authors present numerical results for the axial and transverse excitations.
