Recent experiments on strongly coupled plasmas in a magnetic field and a background of neutrals have revealed that the dust component exhibits a rigid rotation of order a fraction of a radian/s. The rotation arises spontaneously and seems to be in the direction of ion rotation (which in turn is determined by a competition between E⃗×B⃗ and diamagnetic rotations of the ions in the collisional magnetized plasma). In this Letter a possible interpretation of these results, based on the use of fluid equations, is offered.
