We turn now to the study of those aspects of the hydrodynamics of rotating, electrically conducting fluids, which can be expected to play some role in establishing the geodynamo. Current thinking favors convection within the spherical fluid shell between mantle and inner core as a mechanism apt to create the appropriate flow field u on which the magnetic field B can grow andbe maintained against dissipative loss in u and B.
