Folding Paper Model of the Magnetosphere


Structure of the Earth's Magnetosphere.

    This is an average, simplified cut in the noon-midnight direction. Note the magnetopause, the boundary between the magnetosphere and the solar wind.

    On the magnetopause, the cusp is where field lines closing on the Sun's site separate from those going to the tail.

    Note also the plasma sheet in the middle of the tail, source of aurora, magnetic storms and related disturbances
