The problem of unsteady, two dimensional, laminar, boundary layer flow of a viscous, incompressible, electrically conducting and heat absorbing fluid along an inclined semi-infinite moving surface in the presence of a uniform transverse magnetic field and thermal and concentration buoyancy effects is considered. The governing partial differential equations are reduced to a system of non-linear ordinary differential equations which are solved analytically using perturbation technique. The numerical results are presented graphically for different values of the parameters entering into the problem. Finally, the numerical values of the local skin-friction coefficient, local Nusselt number and local Sherwood number are also shown in a tabular form.
