This article presents the experimental study of dust structures formed in striations of glow discharge in an external magnetic field of up to 10 ⁴ G, which was created using a cryomagnet. A magnetic field classification based on probe theory is described. In moderate magnetic field, we obtained stable dust structures. The corresponding experimental setup and the experiment itself are described in detail. Special attention was paid to the influence of magnetic field on the change of the diameter and inter-particle distance of dusty cloud. And, we also determined the dependence of angular velocity of dust rotation on magnetic induction.
