This article addresses the viscous dissipation and Joule heating effects in unsteady magnetohydrodynamic (MHD) three-dimensional flow forced by an exponentially stretching surface. The momentum and thermal equations in the boundary layer regime are reduced into the ordinary differential equations using appropriate transformations. Computations for series solutions of velocity and temperature are first made and then analyzed with respect to influential parameters. Numerical values of skin friction coefficients and local Nusselt number are given and examined. The present results are also found to be in very good agreement with the existing aymptotic solutions.
