An Overview of the Parts of Jupiter's Magnetosphere

Jupiter's magnetosphere is very pointed and bullet-shaped, as shown in this picture, because of the nature of how it is created.

The magnetosphere has many parts, such as the bow shock, magnetospheath, magnetotail, plasmasheet, lobes, plasmasphere, and many electric currents. It is composed of charged particles and magnetic flux.

Jupiter's magnetosphere is the largest object in the solar system. The magnetosphere, however, changes size and shape like a water balloon, depending upon it's interaction with the solar wind.

Jupiter's Plasmasphere

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. Besides ions and...more

The Magnetic Field

The force of magnetism causes material to point along the direction the magnetic force points. This property implies that the force of magnetism has a direction. As shown in the diagram to the left, the...more
