Abstract: This paper deals with the theoretical investigation of Hall current effect on micro polar fluid layer heated from below subjected to horizontal magnetic field in a porous medium. A dispersion relation is obtained for a flat fluid layer contained between two free boundaries using a linear stability analysis theory and normal mode analysis method. In case of stationary convection, the effect of various parameters like medium permeability, coupling parameter, micropolar coefficient, micro polar heat conduction parameter, magnetic field and Hall current parameter has been analyzed and results are depicted graphically. The sufficient conditions for non-existence of over stability are also obtained.
