Fig. 5

Magnetic energy density at \(h=400\) km. The energy densities are calculated separately for the poloidal (left) and toroidal (middle) fields and with the fields combined (right). The patterns are from the Northern hemisphere and correspond to the currents in Figs. 3 (bottom) and 4 (top). The color scale is shown in units of nJ/m\(^3\), and the corresponding field strength is shown in nT
