Abstract The focus of this paper is on the investigation of simultaneous effects of thermal-diffusion and magnetic field in an annulus with a porous medium. The dimensionless forms of the equations were solved analytically using Perturbation method. The solutions of velocity, temperature and concentration equations are derived. Skin-friction, Nusselt number and Sherwood number at the outer surface of inner cylinder are obtained. Selected sets of graphical results illustrating the effects of various controlling parameters involved in the problem on flow formation are discussed. Keywords: Thermo-diffusion, magnetic field, porous medium.
