The Rayleigh-Benard convection occurs, if the fluid between the parallel plates is heated from the bottom plate and cooled from the upper plate above the critical temperature difference. The Rayleigh-Benard convection is seen in the blast furnace. Particularly, the lower Prandtl fluid like the fused metal tends to be time dependence flow. This flow disturbs the pressure field and temperature field, and hinders the formation of the metal with the good crystal. The Lorentz force by DC magnetic field can control this flow. By this way, the time dependence flow changes to laminar flow and the three dimensional structure changes to the two dimensional roll structure. In this thesis, the computations have been performed for Rayleigh-Benard convection in the three dimensional cubic cavity, using GSMAC-FEM with φ method. From the solution, the author investigated the effect of magnetic field to the flow and temperature field and the two dimensional roll structure.
