**ABSTRACT**

The unsteady hydromagnetic free convective flow of viscous, incompressible and electrically conducting fluid past an infinite vertical porous plate with constant suction and heat absorbing sink in the presence of uniform transverse magnetic field has been studied numerically by finite difference method. The effect of Grashof number, Prandtl number, sink strength, Hartmann number and Eckert number on velocity field, temperature distribution, skin-friction and rate of heat transfer have been studied and shown graphically.

**Key words:** Unsteady; Thermal energy; Porous plate; Constant suction; Sink;
