A novel plasma equilibrium in the high-, Hall regime that produces centrally peaked, high Mach number Couette flow is described. Flow is driven using a weak, uniform magnetic field and large, cross field currents. Large magnetic field amplification (factor 20) due to the Hall effect is observed when electrons are flowing radially inward, and near perfect field expulsion is observed when the flow is reversed. A dynamic equilibrium is reached between the amplified (removed) field and extended density gradients.

弱磁化,霍尔为主的等离子库埃特流
高浓度下的新型等离子体平衡,描述了产生中心峰值,高马赫数库埃特流的霍尔机制。使用弱的,均匀的磁场和大的交叉磁场电流来驱动流动。当电子径向向内流动时,会观察到由霍尔效应引起的大磁场放大(因数20),而当电流反向流动时,会观察到接近理想的磁场排出。在放大(移除)场和扩展密度梯度之间达到动态平衡。
