<p>Paramagnetic fluid is weakly attracted toward a magnet depending on the inverse of the absolute temperature. When non-uniform temperature field is formed in an enclosure, colder fluid receives stronger attractive force than hotter fluid. This characteristic can be used in thermal flow control. In this study, numerical simulation of Rayleigh-Bénard convection under a magnetic field from permanent magnets have been performed by the lattice Boltzman method (LBM). The working fluid is assumed as incompressible paramagnetic fluid of which Prandtl number is 13.0. Buoyancy and magnetothermal forces in the LBE are considered by using the Boussinesq approximation. It is found that the shape of steady convection roll cell is affected by the magnetothermal force and the corresponding local heat transfer is enhanced.</p>
