Numerical computations were carried out for a convection of air in a rectangular box under a magnetic field gradient to investigate the influence of a strong magnetic field. The fluid in the rectangular box is heated from a vertical wall and cooled from an opposing vertical wall both isothermally, and thermally insulated from four other walls. The governing parameters are the Rayleigh number, the Prandtl number, and γ, which indicates the strength of the applied magnetic field. The magnetic field induced by an electric-circulating coil was numerically calculated by using the Biot-Savart's law. When the coil was placed near the hot wall, the thermal convection was enhanced, but when the coil was placed near the cold wall, the thermal convection was reduced due to magnetizing force.
