Uranus' Rings

The rings of Uranus extend from 1.49 Ru to 1.95 Ru, which is within a region usually reserved for the plasmasphere. (The Earth's plasmasphere extends from 1 Re to roughly 6 Re).

At Uranus, the rings have a greater sweeping effect due to the extreme tilt of the axis of the magnetic field. The tilt extends the range of the rings down to about 1 Ru.
