In this paper, the effect of suspended particles and rotation on viscoelastic fluid layer heated from below saturating a porous medium in the presence of uniform vertical magnetic field has been studied. The dispersion relation was obtained using the normal mode and the problem has been numerically analyzed by MATLAB. The effect of medium permeability, magnetic field, suspended particles and rotation have been obtained and the effect of suspended particle on the system is very important result. The condition of over stability is also obtained.
