 Conversely, in Jupiter's magnetosphere the rotational energy is stored in the magnetodisk and released when a plasmoid separates from it.Whereas the dynamics of the Jovian magnetosphere mainly depend on internal sources of energy, the solar wind probably has a role as well, particularly as a source of high-energy protons.The structure of the outer magnetosphere shows some features of a solar wind-driven magnetosphere, including a significant dawn–dusk asymmetry.
