Abstract
It is known that a nonAbelian 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 GeorgiGlashow model. We study two different types of finite energy, regular configurations: solutions with net magnetic charge and monopoleantimonopole 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 GeorgiGlashow model are generic and thus a magnetic monopole cannot spin as long as the matter fields feature the usual “monopole” asymptotic behaviour independently of the dynamics of the model. A study of the properties of the dyons and magnetic dipoles in some generalizations of the GeorgiGlashow model supplemented with higher order Skyrmelike terms in the gauge curvature and Higgs fields is given quantitatively.
