To reveal the gas bubble motion in the field of hydromagnetodynamics by means of optical direct observation, we constructed the new experimental system that is consist of non-electrically-conducting gas phase and transparent electrical conducting liquid phase, imposing high magnetic field on the system. In this study, argon gas and sodium chloride solution were used as gas phase and liquid phase, respectively. The Lorentz force was able to be comparable to viscous force and inertial force acting on a gas phase bubble, because the Hartmann number was 2.3 and Reynolds number was 430 for a 3mm diameter argon gas bubble under the imposition of 7T magnetic field. A series of continuous pictures of a single bubble rising up in the saturated sodium chloride solution was taken by using high speed camera, under 0T, 3.5T, and 7T static horizontal magnetic field. From these pictures, the rising velocity of the single bubble was measured. The medians of measured velocities are 0.240m/s with no magnetic field (0T), 0.240m/s with 3.5T magnetic field, and 0.232m/s with 7T magnetic field, respectively. That is, the rising velocity decreased with increase in the magnetic field intensity.
