Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Abstract The experimental results on the influence of an external nonuniform magnetic field on the dust structure dynamics in a stratified glow discharge of helium are presented. The rotation of the dust structure at different values of magnetic field induction was investigated, where magnetic field varied up to 0.2 T. It was found that previously reported effect of the inversion of the rotation direction of a dust structure in an axial uniform magnetic field is strongly hindered by a radial component of the magnetic field induction in the case of a nonuniform magnetic field. This can be explained by the impact of the Lorentz force component appearing due to the axial component of the electric field and radial component of the magnetic field.
