Abstract
The onset of magnetic field on the glow discharge results in the redistribution of plasma flows, which in turn may cause the change of the charge of dust particles levitating in strata. Upon that dusty structure changes its geometric form and inner ordering of particles. In this work, we present the investigation of the influence of magnetic field on dusty structures formed in striation of glow discharge. We detected the variation of geometrical dimensions of structures with magnetic field, and the behavior of interparticle distance was determined. There was obtained the dependence of the concentration of dust particles in normal to vector B cross section of structure on the magnetic induction. Corresponding graph was compared to one of rotation speed, which has three characteristic diapasons. First one is characterized by negative projection of angular velocity Ω on B, two other diapasons are characterized by positive Ω projection and the slope of Ω(B) graph.
