Abstract
Two-dimensional numerical computations were carried out for natural convection of air in a cylindrical enclosure under a strong magnetic gradient field with and without a gravitational field. The magnetic susceptibility of air was represented by an inverse of the absolute temperature following Curies law. The axial location of the electric coil was changed to study the effect of the magnetizing force. The air was almost driven by not the buoyancy force but the magnetizing force even in a gravitational field. However, the air convection was greatly dependent on the axial position of the coil.
