Abstract: Collective motion of charged dust particles, levitated in a disk and a ring that forms in cylindrical electrodeless RF plasma with an axial magnetic field, was investigated experimentally. The measured angular velocities of the disk and the ring are less than 10 rad/s and less than 8 rad/s, respectively. We found that the angular velocity strongly depends on the gas pressure and the strength of the magnetic field while the RF power does not significantly influence the rotation of the dust structure.
