PURPOSE: To move air bubbles in a liq. in the cosmic space where buoyancy is not present by an apparatus wherein a pair of magnetic poles forming a gradient magnetic field are provided in the liq. contg. the air bubbles therein or on the outside thereof and moving the air bubbles in the direction of the gradient magnetic field by utilizing the gradient magnetic field. CONSTITUTION: A pair of magnetic poles 4 and 4 forming a gradient magnetic field are provided in a liq. 2 contg. air bubbles 3 therein or on the outside thereof and a force of the magnetic field is applied on the air bubbles by utilizing the gradient magnetic field based on the difference in vol. susceptibilities of the liq. 2 and gas in the air bubbles 3 to move the air bubbles in the direction of the gradient magnetic field. In this case, the magnetic poles 4 and 4 are bound each other with a soft iron supporting body 15 and when the distance (t) between the magnetic poles is changed along gradient faces 4a and 4b of the magnetic poles 4 and 4, a large gradient magnetic field is generated between both magnetic poles. Therefore, it can be used for removal of mixed air bubbles in a carrying pipe, removal of air bubbles on the surface of electrodes of a battery, removal of air bubbles in the electrophoresis layer of an electrophoresis apparatus, removal of air bubbles in a cooling water and removal of air bubbles in a fuel tank and it is especially effective under microforce of gravity. |
