Abstract
We present an analysis of an electrically conducting viscous fluid over a porous plate in a rotating system. The plate starts impulsively from rest relative to the rotating fluid moving with uniform acceleration in its own plane. Exact solutions are developed for both large and small times. In addition, skin friction is computed. The variations of magnetic field and porosity are displayed and discussed. It is noted that steady state behavior is not achieved even under the simultaneous effects of suction, magnetic field and rotation.
