ABSTRACT
Two-dimensional numerical computations were carried out to clarify the influence of magnetizing force on quiescent air with thermal gradient in a vertical cylindrical container under both gravitational and nongravitational fields. Several sizes and axial positions of a circular electric coil were tested so that the magnetizing force depended on the magnetic gradient. Under both gravitational and nongravitational fields, the convection was induced in quiescent air with thermal gradient by the magnetizing force; however, flow pattern and Nusselt number depended strongly on the size and the axial position of the circular electric coil in addition to the magnetic strength.
