One-dimensional profiles of the x and y components of the neutral-ion drift (left and right panels, respectively) at the end of the simulation. In the upper row, we show the components of the neutralion drift velocity driven by the magnetic tension force per unit volume, and in the lower row we show the components driven by the magnetic pressure force per unit volume. Note that, to zeroth order, the features observed in the lower row of Fig. 2 can be explained by the component of the neutral-ion drift velocity driven by the magnetic tension force per unit volume.
