An attempt has been made to study the Hall effect on MHD forced convection from an infinite horizontal porous plate with dissipative heat in a rotating system with uniform free stream when the temperature at the plate varies periodically with time. The entire system rotates with a constant angular velocity about the normal to the plate. A uniform magnetic field is assumed to be applied along the normal to the plate directed into the fluid region. The governing equations are solved analytically. The expressions for the velocity and temperature field are obtained in non-dimensional form. The skin friction due to primary and secondary velocity field, the rate of heat transfer in terms of Nusselt number with their amplitudes and phases of fluctuating parts at the plate are demonstrated graphically and the effects of Hall current and magnetic field on these fields are discussed.
