The effect of wall conductance on the hydromagnetic Couette flow and heat transfer between two parallel plates in a rotating frame of reference in the presence of an applied uniform transverse magnetic field is studied. An exact solution of the goveming equations has been obtained. It is found that both the primary and the secondary velocities decrease with an increase in wall conduetance parameter. It is also found that the induced magnetic field components increase with an increase in wall conduetance parameter. The shear stresses at the lower plate decrease with an increase in wall conductivity. The heat transfer characteristic has also been studied on taking viscous and Joule dissipation into account.
