A parametric study has been performed for a wide range of Hartmann, Grashof and Prandtl numbers, direction of the applied magnetic field, and aspect ratio of the cavity to examine the effects of an applied magnetic field on buoyancy-driven convection in a cavity. The flow field, temperature distribution, and local heat transfer rates have been considered to analyze the results. The flow is weakened and the heat transfer rate is reduced with an increase in the strength of the magnetic field. The flow oscillations at high Grashof numbers are also suppressed by the magnetic field of a sufficient strength. The results for tall and shallow cavities indicate that the effect of magnetic field is much stronger when it is directed normal to the primary flow direction.
