The objectives of the present study are to investigate the effects
of heat and mass transfer on the unsteady flow of a perfect
conducting polar fluid over a flat sheet with a linear velocity in
the presence of thermal radiation. Successive approximation method
developed in Zakaria [Appl. Math. Comput. 10 (2002), Appl.
Math. Comput. 155 (2005)] is adopted to solve the problem. The
effects of Alfven velocity, mass transfer, various material
parameters, Prandtl number, Schmidt number and relaxation time on
the velocity, angular velocity, temperature and concentration are
discussed and illustrated graphically.
