Figure 2. Blockdiagram illustrating coupling between the horizontal wind U and pressure p via the Ampere force jx Bo, and the Lorentz force Ux Bo. Here j is the electric current density, Bo the geomagnetic field, h the equivalent depth, σ the electric conductivity, and E the electric polarization field. In a self-consistent treatment of the coupled system, gate B must be closed. In conventional dynamo theories, gate B is open.
