A solution for the case of low Reynolds number Re (suction Reynolds number) and Magnetic field M is discussed. Expressions for the velocity components are obtained. The governing non-linear differential equations are solved using perturbation method analytically. Using matlab for the calculating the data of the graph. The graph of axial and radial velocity profiles have been drawn in different magnetic field and different height of the channel.

Introduction The flow of fluid in porous medium is very important prevalent in nature and therefore the study of flow of fluid through porous medium has become of principle interest in many and engineering applications. Many research workers have investigated the steady, incompressible laminar flow of fluid in a channel with uniform porous bounding walls. Cox and King [4], studied the asymptotic solution of High order non-linear ordinary differential equation. In the earlier analysis majority have used no slip boundary conditions, but the experimental investigation reveals the existence of slip velocity at the porous bounding wall and is connected with presence of a thin layer of stream wise moving fluid just below the surface of the porous medium. Beavers et al [2], has studied the experiments on coupled parallel flow of fluid in a channel and a bounding porous medium.
