Experimental results on the influence of an external inhomogeneous magnetic field created in the end areas of the coil on the dynamics of a ring-shaped dust structure in a stratified glow discharge in argon are presented. The rotational behaviour of the ring was investigated at different magnetic fields in the range up to 16 mT. It was found that the direction of rotational motion of dust particles in an inhomogeneous magnetic field depends on the direction of its radial component. A theoretical model was proposed to explain the experimental observations.

弱非均匀磁场中的环状尘埃结构

给出了在氩气中分层辉光放电中线圈端部区域产生的外部不均匀磁场对环形粉尘结构动力学影响的实验结果。在高达 16 mT 的不同磁场下研究了环的旋转行为。人们发现，尘埃粒子在非均匀磁场中的旋转运动方向取决于其径向分量的方向。提出了一个理论模型来解释实验观察结果。
