A new investigation on MHD Stoke's flow with induced magnetic field effect

Unsteady MHD Stoke’s flow of a viscous incompressible electrically conducting fluid past a flat plate under the influence of a transverse magnetic field is studied. The induced magnetic field produced by the motion of an electrically conducting fluid which perturb the original magnetic field. Since the plate is considered perfectly conducting, the magnetic field does not penetrate outside the region space. This problem is solved by employing Laplace transform method. The effect of induced magnetic field plays an important role in determining the MHD Stoke’s flow behaviour. Numerical results of velocity distributions, induced magnetic field distributions and the shear stress at the plate are depicted graphically for various values of flow parameters. This gives a physical interpretation obtained by the numerical results.
