  A novel plasma equilibrium in the high-$\beta$, 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.
