16 Drift currents: gg rgrg At y=0, for any given particle we have: where : is the Assume to lowest order f is independent of  g, and dependent just on y.

17 is the phase space density of particles whos gyro center is y gc and gyro phase is  g. Assume to lowest order f is independent of  g, and dependent just on y. Note that the drift current does not depend on the particle’s charge, just on their mass.
