Abstract: The computational study of the combined effects of radiation and hydro- magnetics on the natural convection flow of a viscous, incompressible, and electrically conducting fluid past a magnetized permeable vertical plate is presented. The governing non-similar equations are numerically solved by using a finite difference method for all values of the suction parameter ζ and the asymptotic solution for small and large values of ζ. The effects of varying the Prandtl number P_r, the magnetic Prandtl number Pr_m, the magnetic force parameter S, the radiation parameter R_d, and the surface temperature θ_w on the coefficients of the skin friction, the rate of heat transfer, and the current density are shown graphically and in tables. An attempt is made to examine the effects of the above mentioned physical parameters on the velocity profile, the temperature distribution, and the transverse component of the magnetic field.
