An analysis is carried out to study free convective flow and heat transfer of an viscous incompressible electrically conducting fluid over a stretching sheet. Using the similarity variable, the partial differential equations are reduced to ordinary differential equations by using R-K Gill method along with shooting technique. Numerical results of the local of the local skin friction coefficient and the local Nusselt number as well as the velocity and temperature profiles are presented through graphs for different physical parameters, such as the Prandtl number(Pr), Grashof number(Gr), permeability parameter(AP) and ratio of the free stream velocity to parallel wall parameter() and the radiation parameter(R).
