Visualization of the magnetothermal air jet induced by the Kelvin force in two coaxial circular pipes was carried out by means of numerical computations in order to understand this phenomenon more deeply and to consider its possible engineering applications. The outer pipe with open ends corresponds to the bore space of the super-conducting magnet. The inner pipe with open ends is assumed to be placed inside this bore space. The central region of the inner pipe is heated isothermally and the other region is thermally insulated. The super-conducting magnet as a source of the Kelvin force was replaced with one-turn electric coil. The upward magnetothermal air jet was created when the circular electric coil was placed at the lower end of the heated region. On the other hand, the downward magnetothermal air jet was created when the circular electric coil was placed at the upper end of the heated region.
