A weakly ionized plasma contained in the gadolinium atomic beam produced by electron beam heating was passed led to a magnetic field of 01.5kG between iron cores. When the magnetic field was applied, the instability appeared in the ion saturation current. With increasing the magnetic field, the ions detected by the ion collectors decreased and no ions were detected at all. The magnetic field intensity at which the plasma does not flow and ions are not detected does not depend on plasma ion density. At this magnetic field, Larmor radius of ions are two times wider than plasma width. In addition, it is found that the plasma contained in the atomic beam can be removed by the magnetic field.
