摘要：

Vertical spread of fine-particle clouds is observed in a weakly ionized argon de plasma by applying axial magnetic field in vertical direction, using a double-plasma method. The fine particles are trapped radially to form a large-volume fine-particle cloud along the magnetic field. The fine-particle cloud rotates around its vertical axis, as a whole, under the presence of the vertical magnetic field. We observe a small-scale convection motion of fine particles near the surface of the cloud. Changing the discharge conditions also excites unstable fluctuations propagating along the magnetic field.
