      An attempt has been made to study hydromagnetic oscillatory flow of an electrically conducting incompressible viscous fluid through a porous medium bounded by vertical porous plates with heat source and chemical reaction. One plate of the channel is kept stationary and the other is oscillating with uniform velocity. The plates of the channel are subjected to constant injection and suction velocities respectively.The novelty of the present study is to investigate the combine effects of heat source and the Soret effects in the presence of chemical reaction. The closed form solutions of the governing equations are obtained for the velocity, temperature and concentration profiles.Effects of the various parameters on the velocity, temperature, concentration, skin friction, the rate of heat and mass transfer coefficients are nimerically evaluted and discussed with the help of graphs. It is interesting to note that an increase in chemical reaction parameter or Soret number or permeability parameter reduce the fluid velocity and enhance the skin friction coefficients . Further, it is observed that the effect of increasing heat source parameter is to accelerate the temperature and velocity of the flow at all points while decelerate the concentration and skin friction coefficients.
