The effect ofboth the magnetic field and mass transfer on buoyancy induced flow over vertical plate embedded in a non-Newtonian fluid saturated porous medium has beenmodeled andanalyzed. Thepower-lawfluidmodel is used to characterize the non-Newtonian fluid behavior. Similarity solution for the transformed governing equations is obtained with prescribed variable surface heat flux. Numerical results for the details of the velocity, temperature and concentration profiles arepresented.Excess surface temperature as well as concentration gradient atthe wall associated with heat flux distributions, which are entered in tables, have been presented for different values of the power-law indexnbuoyancy ration B1, magnetic field parameter Mnand the exponent λas well as Lewis number Le.
Key words: Porous media, mass transfer, magnetic field, non-Newtonian fluid.
