Wheeling Spokes - Saturn

[jjohnson]

There appears to be a visual similarity among the images of the Sun's corona, Enceladus's south pole 'geysers', and the spoke patterns in Saturn's rings. All appear to be radial plasma discharges,tapering (pinching?) together with increasing distance although I can't be sure whether Saturn's spokes are discharges with radial motion or a pattern of an electrostatic organization.

Do the rings and spokes follow Saturn's rotation period precisely? If so, are the inner rings rotating more quickly than the outer ring sections in a Newtonian gravity model, or do they rotate like a galactic disk, as a rigid disk structured by electromagnetic steering forces? Is there relative motion ("sliding") between rings and spokes? Time lapse movies would be helpful, but hard to get long-term because of Cassini's busy orbitals, and other tasking. Need a Saturn-synchronous satellite in place, NASA! Maybe 3.
