The magnetic Kelvin force generated by a superconducting magnet system can damp the natural convection during crystal growth and thus the crystal quality can be improved. The magnetic field used to generate micro-gravity environment was theoretically analyzed. Based on the specific setup of the superconducting magnet system, the magnetic accelerations as well as the magnetic field intensities were numerically simulated and the current densities in the coils required to generate micro-gravity for various crystal growth conditions were calculated. The flow fields and temperature fields were obtained for the water natural convections in the gravitational field only and in the micro-gravitational environment respectively. The results show that the micro-gravity environment during crystal growth can be achieved by the specific setup of the superconducting magnet system and the appropriate current densities in the coils.
