Current Systems of Jupiter

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 places, 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.
