Fig. 11From: Auroral substorms as an electrical discharge phenomenonThe inflation of the magnetosphere by trapped plasma. a The resulting distortion of the earth’s dipole field and the magnetic field produced by the trapped plasma, b the distribution of vectors of the magnetic field produced by trapped plasma, and c the distorted field by the inflation; the dashed lines indicate the distortion before the power ε is increased above 1018 erg/sBack to article page
