In the present work numerical computations were carried out for the convection of air in a cubic enclosure under strong magnetic field in a space conditions. The driving force for the convection is due to a magnetizing force. Since the fluid has a magnetic susceptibility which varies with temperature due to the Curie’s law, the magnetic buoyancy force drives the fluid motion. Magnetic field was generated by an electric current flowing through the single electric coil which was placed at various elevations Zc and calculations were carried out for various combinations of the diameter of the coil. For example with the coil placed in a horizontal plane with its center in the center of the enclosure, the strongest magnetic effect was obtained for a smallest diameter. However, it was shown that nature of the convection was strongly dependent on the magnetic field distribution and presented characteristic is a good clue how to control the convection and the heat transfer rate of air in a space.
