Abstract
It is known that a non-Abelian magnetic monopole cannot rotate globally (although it may possess a
nonzero angular momentum density). At the same time, the total angular momentum of a magnetic dipole
equals the electric charge. In this work we question the generality of these results by considering a number
of generalizations of the Georgi-Glashow model. We study two different types of finite energy, regular
configurations: solutions with net magnetic charge and monopole-antimonopole pairs with zero net
magnetic charge. These configurations are endowed with an electric charge and carry also a nonvanishing
angular momentum density. However, we argue that the qualitative results found in the Georgi-Glashow
model are generic and thus a magnetic monopole cannot spin as long as the matter fields feature the usual
“monopole” asymptotic behavior independently of the dynamics of the model. A study of the properties of
the dyons and magnetic dipoles in some generalizations of the Georgi-Glashow model supplemented with
higher order Skyrme-like terms in the gauge curvature and Higgs fields is given quantitatively.
