The importance of these “Birkeland currents” to the coupling between the magnetosphere and the polar ionosphere is emphasized by their intensity, which ranges between 10 6 and 10 7 amperes, and by the energy which they dissipate in the upper atmosphere, which ... WebBirkeland current studies noted above. Even though the east-west magnetic field showed many localized perturba-tions associated with individual arcs and adjacent return currents, there was usually a clear region of increasing and a region of decreasing azimuthal magnetic field which were associated with the broad Birkeland current systems.
