  • The stability of the closed magnetosphere is studied for the case in which the interplanetary field opposes the terrestrial field in the equatorial plane. In the limit of a vanishing solar wind, the closed equilibrium configuration, consisting of a spherical geomagnetic cavity surrounded by a field-reversing current layer, is shown to be unstable. It transforms spontaneously into an open configuration of Dungey's type, where the earth's polar field lines reach into interplanetary space. The… CONTINUE READING
