The present study is devoted to investigating the influences of magnetic field on buoyancy induced flow over vertical flat plate embedded in a non-Newtonian fluid saturated porous medium. The Ostwald-de Waele power-law model is used to characterize the non-Newtonian fluid behavior. A similarity solution for the transformed governing equations is obtained with a prescribed variable surface heat flux. Numerical results for the details of the velocity and temperature profiles are shown on graphs. Excess surface temperature has been presented for different values of the power-law index n, magnetic parameter Mn* and the exponent 'lambda'.
