In order to study the liquid metal natural convection under the magnetic eld with different wall conductivity, the natural convection of liquid metal in the 3D cubic enclosure under the magnetic field is numerically simulated. Numerical simulations show that the results obtained without the magnetic field are in agreement with the existing experimental results. Because the induced current and reversed Lorenz force are produced by the liquid metal flowing in a magnetic field, and the reversed Lorenz force would inhibit the natural convection flow and heat transfer of liquid metal. With the increase of the intensity of magnetic field, inhibition of liquid metal natural convection by the reverse Lorentz force is obvious. Conductive wall has an important effect on the natural convection than insulation wall.
