“…One of the directions for the subject study is investigation of the influence of the magnetic field on the plasma-dust structures formed in the striation of DC discharge. Also, the inverse rotation of plasma-dust structures in a magnetic field was found [1][2][3][4][5].…”

Abstract. At present, there are several theoretical assumptions that the rotation of the plasma-dust structures in the striation in a magnetic field can be caused by the presence of a number of irregularities. In this paper one of the irregularities, such as the influence of the edge effect at the ends of the solenoids on the rotational motion of plasma-dust structures in the stratum of the glow discharge, was experimentally investigated.

“…Probably, the influence of magnetic field is especially effective in the conditions of a glow discharge due to very intensive fluxes of plasma. Magnetic field causes the competition between several elementary mechanical processes resulting in the complex dynamics of rotation motion of dust structures in the glow discharge strata …”

“…One more motivation for studying of dusty plasma under the influence of magnetic field is the research of its magnetic properties. The dust particle that is quickly rotating around the center of inertia generates the magnetic moment up to 10 4 to 10 5 Bohr magnetons. It interacts with external magnetic field, and this is why the particle's axis of rotation varies; and finally varying the interaction of the particle surface with plasma fluxes.…”

In this work, we present the investigation of the formation features and internal structure of dust clouds created in plasma of glow discharge in the external magnetic field corresponding to a range of moderate and strong fields, at which the ion component is magnetized. The analysis of the plasma magnetization in the presence of dust components is carried out. We defined the values of magnetic induction at which the changes in dynamics of plasma particles in magnetic field in light inert gases are expected. The experimental setup was built in two versions. For the purpose of generating of magnetic field, the first setup was equipped with ordinary magnetic coils, and the second one included a superconducting solenoid. The discharge tubes, the main chambers where plasma was ignited and maintained in a glow discharge in lowered pressure, also have certain peculiarities, which we describe below. While using helium as a bulk gas, our study focused only on the dust trap in the region of narrowing discharge current. For neon, we used two traps: the striation trap and one just mentioned above placed in the narrowing of the discharge tube. As a result, the steady dust structures in a glow discharge under the magnetization of ions and electrons were obtained for the first time. Dust structures were rotated and tended to form a dust cluster and shell structure. A number of parameters of magnetization achieved in experiments were calculated.

“…One of the productive methods of studying a complex plasma consists in imposing an external influence and an observation of the response of the system. Imposing a magnetic field on low-temperature plasma with the dusty component has revealed new mechanical and thermodynamic properties, namely, change of the order of the system and kinetic temperature of the particles, of viscosity [5][6][7][8], as well as the magnetic properties because the dusty component possesses paramagnetism [9][10][11]. Probably the most interesting feature of dusty plasma in magnetic field is the complex dynamics of the rotational motion which shows an inversion of the direction angular velocity of the rotation of dust structure.…”
