Summary A more accurate discussion than in an earlier paper is given of the inflation of the geomagnetic field during the main phase of a magnetic storm. The radial velocity of the injected plasma is found to be of the order of 1 km s ‐1 . Energy consideration suggests that a proton plasma of energy density of 2.4 × 10 −7 erg cm ‐3 would be more than adequate to supply the magnetic energy of the storm.
