Detailed observations of 100-eV hydrogen plasmas moving in a linear quadrupole
and a toroidal octupole magnetic field show that the plasmas polarize and
that the field lines quickly become equipotentials. The plasmas E x B drift
with negligible diamagnetism in double vortex flow patterns similar to
the self-consistent solutions of Poukey. The agreement is not perfect presumably
because the uniform field and steady state assumed in the theory are lacking
in the experiments.
