The equations governing the flow magnetic and temperature fieldare reduced to dimensionless convenient form using the free variable transformations and solvednumerically by using finite difference method. Effects of physical parameters like Prandtl number,Pr, the conduction-radiation parameter Rd, magnetic field parameter S, magnetic Prandtl numberPm, mixed convection parameter λ, and the surface temperature, θw on the local skin friction coefficient Cfx, local Nusselt number, Nux, and coefficient of magnetic intensity, Mgx againstthe local transpiration parameter ξ are shown graphically. Later, the problem is analysed by usingseries solution for small and large values of ξ, and the results near and away from the leadingedge are compared with numerical results obtained by finite difference method and found to be ingood agreement.
