The aim of the present analysis is to examine the magnetic and mass diffusion effects on the free convection flow when the plate is made to oscillate with a specified velocity. It is assumed that the plate is embedded in the porous medium. It is noticed that as the `Sc' increases the velocity field decreases. Further, it is observed that on the boundary (y = 0) the Schmidt number does not have any effect, while as we move far away from the plate the effect is found to be significant. Also, it is found to be oscillatory in this nature as we move far away from the plate. It is noticed that `Pr' number is increased the velocity field decreases almost exponentially when Pr = 0.71. However, in all other cases the effect is found to be oscillatory as we move far away from the plate. It is noticed that as `Sc' increases the concentration is found to be decreasing. When the applied magnetic effect is held constant and as Pr increases an increasing trend in the skin friction is noticed.
