    Abstract: This paper presents the study of unsteady flow of an incompressible electrically conducting viscous fluid in a rotating porous media, with a variable pressure gradient and in the presence of hall current. Here we consider three different cases, like impulsive change, cosine and sine oscillations of pressure gradient. Here, it is proved in this paper that, the rotational and Lorenz forces are having significant effect on velocity profile in the presence of pressure gradient and hall current.

    Keywords: Unsteady flows, rotating channels, Hall current effects, pressure gradient, impulsive change, Cosine Oscillations and Sine Oscillations..
