Ion drag as a mechanism of plasma dust structure rotation in a strata in a magnetic field

Abstract:
In experiments on complex plasmas, afixed strata region in which the levitation of dust structures is observed is investigated using the method of probing by calibrated dust particles of different sizes in an applied magnetic field under elevated pressures. The measured azimuthal velocity of the probing particles corresponds to the action of the ion drag force for 4 $\mu$m-size particles and to the entrainment by the rotating gas owing to the electron vortex flow inside the strata for 1 $\mu$m-size particles. Extrapolation to pressures and magnetic fields in which the rotation inversion of dust structures is observed in experiments shows that the ion drag is the dominating force causing rotation with a negative projection of the angular velocity onto the magnetic induction.
