Three-dimensional numerical computations are carried out to clarify the effect of magnetic force on natural convection of air in a cylindrical enclosure with a heated disk at a bottom center. In the present numerical computations, the magnetic gradient generated inside the bore space of super conducting magnet is replaced by that generated by the circular electric coil. When the magnetic center is placed below the heated disk, the magnetic force enhances the natural convection. As a result, the average Nusselt number on the heated disk increases. In contrast, when the magnetic center is placed at either the central height of the enclosure or the upper end plate, the magnetic force rather suppresses the natural convection. As a result, the average Nusselt number on the heated disk decreases.
