An analysis has been carried out to obtain the nonlinear MHD flow with heat transfer characteristics of an incompressible, viscous and Boussinesq fluid on a vertical stretching surface with power-Iaw velocity. An approximate numerical solution for the flow problem has been obtained by solving the goveming equations using a numerical technique. A magnetic field is applied transversely to the direction of the flow. Adopting the similarity transformation, goveming nonlinear partial differential equations of the problem are transformed to nonlinear ordinary differential equations. Then the numerical solution of the problem is drawn using the Runge Kutta Gili method. NumericaI caIculations are carried out for different values of the dimensionless parameters in !he problem and an analysis of the results obtained show that the flow field is influenced appreciably by the presence of the magnetic field and thermal stratification effect.
