Electromagnetic coupling between the fluid core and its solid neighbours
At low-frequency, the nearly geostrophic force balance in the fluid core constrains axisymmetric fluid motions to be purely azimuthal and independent of position along the rotation axis. Fluid motions can thus be described by a set of concentric rigid cylinders, which are free to rotate about the...
