North Pole is moving

Norther Magnetic Pole is moving rather fast towards Siberia with rate between 55-60 km per year. On the other hand the magnetic field of Earth has been weakening. Could these phenomena relate to each other? There is also the long-standing mystery of the maintenance of the magnetic field B_E of Earth: one would expect that the dissipation for the currents generating B_E would lead to a rather rapid disappearance of B_E. A further mystery is that the orientation of B_E is different from the orientation of the rotation axis and can differ from it very much: this is not what one would expect if the rotational flow of liquid metal in the outer core is responsible for the entire B_E.

In TGD Universe B_E having nominal value .5 Gauss has two parts: monopole flux tube part and non-monopole part analogous to Maxwellian magnetic field. Monopole part is perhaps identifiable as the endogenous magnetic field B_end = 2B_E/5=.2 Gauss explaining Blackman's findings about quantal effects of ELF em fields on vertebrate brain in terms of the identification of dark matter as phases of the ordinary matter with effective Planck constant h_eff=n×h₀. No currents are needed to maintain the monopole part whereas the non-monopole requires current maintaining it. B_end corresponds to a flux tube radius of about L(169) then the minimal radius for flux tube would be about L(163) ≈ 640 nm.

Non-monopole part of B_E would be naturally parallel to the rotation axis of Earth since it is generated by the rotation of the outer core. Monopole part could correspond to the magnetic axis. The change of the direction of B_E would be induced by the change of the direction of the monopole part and induce currents changing the non-monopole part. Monopole part together with this refreshing mechanism would explain the maintenance of B_E (see this). The magnetic North pole is recently moving rather rapidly towards Siberia and the strength of B_E has been decreasing suggesting that the refreshing operation has been activated. This mechanism would force transfer of energy needed to refresh the current maintaining the non-monopole part.
