An unsteady two-dimensional and mass transfer flow of a visco-elastic, incompressible and electrically conducting fluid saturated in a porous medium with suction or blowing is studied. The permeability of the porous medium fluctuates with time about a constant mean. The surface absorbs the fluid with constant velocity and the velocity oscillates depending on the stretching rate (b). Analytical solutions for the velocity, skin friction and concentration are obtained. The influence of various parameters entering into the problem are discussed. The velocity of the visco-elastic fluid is found to decrease in the presence of the magnetic field and porous media as compared to the study of viscous fluid. It is also found that the effect of unsteadiness in the wall velocity and skin friction are found to be appreciable.
