In this talk I will present a variational convergence result originating in the Landau-de Gennes model for nematic liquid crystals describing the Saturn ring effect around a spherical particle with external magnetic field. I will describe some properties of the limit functional and explain how this result can be generalized to non-spherical and in particular non-convex particles.
