The study of hydromagnetic heat and mass transfer in MHD flow of an incompressible, electrically conducting,
viscous fluid past an infinite vertical porous plate along with porous medium of time dependent permeability under
oscillatory suction velocity normal to the plate has been made. It is considered that the influence of the uniform
magnetic field acts normal to the flow and the permeability of the porous medium fluctuate with the time. The
problem is solved, numerically by Galerkin finite element method for velocity, temperature, concentration field and
the expressions for skin – friction, Nusselt number and Sherwood number are also obtained. The results obtained are
discussed for Grashof number (Gr > 0) corresponding to the cooling of the plate and (Gr < 0) corresponding to the
heating of the plate with the help of graphs and tables to observe the effects of various parameters.
