Abstract: In this paper, the magnetic field effects on non-Newtonian power-law fluids for heat transfer over a stretching flat sheet in the presence of heat generation are studied numerically. The governing continuity, momentum, and energy equations are converted into a system of non-linear ordinary differential equations by means of similarity transformation. The resulting system of coupled non-linear ordinary differential equations is solved numerically. Numerical results were presented for velocity and temperature profiles for different parameters of the problem as the power-law fluid index, magnetic field parameter, temperature buoyancy parameter, Prandtl parameter, heat source parameter, stretching parameter and temperature exponent parameter and other. Also the effects of the pertinent parameters on the skin friction and the rate of heat are obtained and discussed numerically and illustrated graphically
