The boundary layer flow and heat transfer due to plate stretching with a power-law velocity distribution in the presence of a transverse magnetic field is studied.A special form of magnetic field is chosen so as to yield the similarity equations.It is assumed that the induced magnetic field is negligible which is justified for flow at small magnetic Reynolds number;the external electric field is zero and the electric field due to polarization of charges is also negligible, the heat due to viscous and Joule dissipation are neglected.Numerical solutions of the resulting momentum boundary layer and the thermal boundary layer equations are determined using Runge-Kutta Merson method.The effects of the magnetic field on the velocity and the temperature of the conducting fluid are analysed.Moreover, the influence of Prandtl number on non-uniform surface temperatue is investigated in this discussion
