Abstract :
The present study is carried out to examine the effects of heat absorption and porosity of the medium on flow model. In the study of motivated by several important problems like maintenance and secular variation of earth`s magnetic field, the internal rotation rate of sun, the structure of rotating magnetic stars, the planetary and solar dynamo problems. The model consists of an unsteady flow of a viscous, incompressible and electrically conducting fluid. The flow is along an impulsively started oscillating vertical plate with variable mass diffusion. The magnetic field is applied perpendicular to the plate. The fluid model under consideration has been solved by Laplace transform technique. The numerical data obtained are discussed with the help of graphs and table. The effects of velocity and skin fraction are studied for different parameters like phase angle, thermal Grashof number, mass Grashaf number, the permeability of the medium, heat absorption and rotation parameter.
