The behaviour of magnetohydrodynamic (MHD) natural convection flow from a porous vertical plate is studied with respect to variable viscosity. To model the flow, the governing boundary layer equations are first transformed into a non dimensional form. The resulting non linear system of partial differential equations is then solved numerically using finite difference method together with Keller-Box scheme. The study shows that the variation of viscosity influences the surface shear stress (skin friction coefficient) and the rate of heat transfer (local Nusselt number). It has an effect on velocity as well as temperature profiles. Studied has been performed with a selection of parameters set consisting of magnetohydrodynamic parameter M, viscosity variation parameter γ, Prandtl number Pr. Results are shown graphically and tabular form and the comparison agrees well with a published paper.
