A theoretical analysis of free convective two dimensional unsteady flow of a visco-elastic incompressible fluid through a porous medium bounded by an infinite vertical porous plate subjected to a uniform suction is presented under the influence of a uniform transverse magnetic field. Approximate solutions for velocity distribution,fluctuating parts of the velocity profiles,amplitude and phase lead of the skin friction at the plate has been found by using perturbation technique. The effects of various parameters has been studied, discussed numerically and shown graphically. And numerical values of coefficient of skin friction for various values of physical parameters are presented.
