Abstract: In this paper the problem of visco-elastic fluid layer heated from below in the presence of uniform vertical magnetic field with Hall current in porous medium is discussed here and obtained a dispersion relation. Using normal mode analysis, from this dispersion relation, we observed that the medium permeability k₁ has destabilizing effect, the magnetic field has stabilizing effect and this stabilizing effect is independent of Hall current, Hall parameter has destabilizing effect and the sufficient condition for the non-existence of over-stability are given as .
