A discussion of the consequences of an electric field of broad scale across the magnetosphere and the dynamics of adiabatically drifting plasma. It is shown that emplacement of main-phase ring current, local acceleration of auroral primaries and other zone electrons, and distribution of fluxes of energetic electrons in the outer magnetosphere are possible consequences of such an electric field. A subsidiary result in the elimination of a severe restriction on charge-separation theories of the auroras and ionospheric current systems.
