The present work is concerned with unsteady two-dimensional
laminar flow of an incompressible, viscous,
perfectly electrically conducting fluid past a nonisothermal
stretching sheet in the presence of a transverse magnetic field
acting perpendicularly to the direction of fluid. By means of the
successive approximation method, the governing equations for
momentum and energy have been solved. The effects of surface mass
transfer $f_{\omega}$ , Alfven velocity $\alpha$ , Prandtl number
$P$ , and relaxation time parameter $\tau_0$ on the velocity and temperature have been discussed. Numerical results are given and illustrated graphically for the problem considered.
