A number of unusual electromagnetic scattering effects for magnetic spheres are described. When ε = µ, the backscatter gain is zero; the scattered radiation is polarized in the same sense as the incident radiation. In the smallparticle (or long-wavelength) limit, conditions are described for zero forward scatter, for complete polarization of scattered radiation in other directions, and for asymmetry of forward scatter to backscatter. The special case in the small-particle limit of <i>m</i> = 1, i.e., µ = 1/ε, provides interesting special instances of complete polarization and forward-scatter-to-backscatter asymmetry.
