Current Systems of Jupiter
Scientists are still studying Jupiter's currents to understand them completely. Currents in a magnetosphere are like arteries in the human body. They are the manifestation of particles being carried from one region to another. Currents are a very important part of the interaction of the solar wind, the magnetosphere, and a planet's atmosphere.
The most powerful currents in the magnetosphere are those which power the Jovian aurora. As shown in the figure, the Jovian aurora is thought to come from two sources, Field-Aligned currents (FAC's) from the moon Io, and from currents carrying particles from somewhere deeper in Jupiter's magnetotail.
If you would like to know a little bit more about current systems, why not look at current systems in the Earth's magnetosphere.
