Fig. 9From: On the modelling of M2 tidal magnetic signatures: effects of physical approximations and numerical resolutionEffect of galvanically decoupled mantle. Differences between the 2-D solution and a unimodal solution without toroidal magnetic field, i.e. galvanically decoupled from the underlying conductive mantle. Both solutions were calculated at the Earth’s surface with the elmgFD code at \(j_{\mathrm{max}}=480\)Back to article page
