Jupiter's magnetosphere is practically all plasmasphere. Jupiter's magnetosphere is filled with plasma. Most of the plasma comes from the donut-shaped cloud (torus) of material from Io.
Particles enter the plasmasphere from the atmosphere as well as the magnetotail. Particles leave the plasmasphere at the north and south poles. When these particles collide with the atmosphere, they create the aurora.
Jupiter's plasmasphere makes powerful radio noises. Radio signals and other waves which come from the plasmasphere include whistler waves, chorus and hiss.
