Experimental investigation of the rotation of dust structures in a DC discharge in a longitudinal strong magnetic field up to T has been performed for the first time. The main problem is the occurrence of discharge instability in moderate fields , which we have been able to solve. The dependence of rotation velocity on B is obtained. In fields the results are consistent with previous experiments, including rotation inversion. At (with the exception of the instability region), a much slower increase in the rotation velocity with increasing B is observed than at . In the region , there was a sharp slowing-down of the rotation, apparently due to the instability of the discharge, and a partial degradation of the dust structure occurred.
