Abstract. The combined effects of Hall current and thermal radiations on unsteady flow of an electrically conducting fluid past an impulsively started infinite vertical porous plate with variable temperature is studied. A magnetic field of uniform strength is applied along an axis perpendicular to the plate and the entire system rotates about this axis. The plate temperature is raised linearly with time. An exact solution is obtained by Laplace Transform method. The dependence of the amplitude and phase difference of velocity and skin-friction on various parameters are discussed in detail.
