Experiment for the natural convection of liquid Gallium in a cube is carried out with external electric current added at the center height of heated and cooled vertical walls under the uniform magnetic field that is horizontal to the hot and cold walls. Liquid Gallium in a cube is affected by the Lorentz force induced by the added electric current and magnetic field, resulting unexpected flow pattern may occur inside the cube. However, it is difficult to visualize the inside flow directly, temperatures along the hot and cold walls were measured and the average Nusselt number was estimated with and without added electric current. When the electric current is applied, the Nusselt number differs from that without electric current as the strength of external magnetic field is increased.
