  Saturn's dynamic F-Ring still presents a challenge for understanding and
explaining the kinematic processes that lead to the changing structure visible
in our observations of this ring. This study examines the effect of Saturn's
magnetic field on the dynamics of micron-sized grains that may become
electrically charged due to interaction with plasma in Saturn's rigidly
corotating magnetosphere. The numerical model calculates the dynamics of
charged dust grains and includes forces due to Saturn's gravitational field,
the plasma polarization electric field, a third order harmonic expansion of
Saturn's magnetic field, and the F Ring's Shepherding moons, Prometheus and
Pandora.
