In this article plane wave propagation in a rotating fibre-reinforced medium under the action of a magnetic field of constant magnitude has been investigated. The material is supposed to be porous in nature and contains voids. Following the concept of Cowin and Nunziato , the governing equations of motion have been written in tensor notation taking into account of rotation, magnetic field effect and presence of voids in the medium and the possibility of plane wave propagation has been examined. Some particular cases have been derived from our general results. Effects of various parameters on the velocity of wave propagation have been presented graphically.
