    "abstract": "A high-density magnetized plasma has been studied for understanding of plasma\ndynamics in partially ionized plasmas. Ion flow field has been obtained\nexperimentally, and is shown to be associated with a vortex formation. The most\nremarkable result is that the direction of rotation is opposite to that of the\nExB drift. Measurement of neutral density profile reveals that there is a steep\ndensity gradient of the neutrals around the vortex, suggesting that the\ngeneration of inward momentum of the neutrals due to the density gradient. The\nmomentum is transfered to ion with charge-exchange collision, and cause\neffective force on the ion. The present experiment shows that this effective\nforce may dominate the ambipolar-electric field and drive the anti-ExB vortical\nmotion of ions.",
