This paper deals with the theoretical investigation of the effect of suspended particles on a rotating layer of a ferromagnetic fluid heated from below. For a fluid layer between two free boundaries, an exact solution is obtained using a linearized stability theory and normal mode analysis. For the case of stationary convection, it is found that suspended particles have a destabilizing effect, whereas rotation has a stabilizing effect on the onset of instability. The principle of exchange of stabilities is not valid for the problem under consideration, whereas in the absence of rotation it is valid under certain condition.
