This article presents the results of experiments on the effect of an external magnetic field created by the Helmholtz coil on the dust structures, which were suspended in the strata of a direct current glow discharge.Observations were carried out in three regions (between the coils (II region), under the coil (III region), and above the coil (I region)). An interesting be-havior of dust structures in the stratum was discovered, which was not previously reported in similar works. The dust structure rotates clockwise above the coil and counterclockwise under the coil, while the dust structure located between the coils does not rotate.Monodisperse mela-mine formaldehyde particles were used as dust particles.The experimental data were processed using the PIV (particle image velocimetry) method at different magnetic field inductions in dif-ferent areas.An interpretation was proposed that the rotation of dusty structures is due to the in-fluence of the component of the Lorentz force arising from the axial component of the electric field and the radial component of the magnetic field.
