On the Earth Magnet page of this site I apply Coriolis Effect to confirm that the induced magnetic field should appear of south magnetic polarity at the north and south geographies. That helped explain the Plasmoids or patches of south magnetic field polarity in Antarctic next to the strong north polarity magnetic pole down there. On the post titled Another Proof that the Magnetic Configuration of Earth has Induced and Permanent fields I introduce the Inner Core as a dipole permanent magnet due to the characteristics its inner and outer layers enjoy. Those characteristics are presented by a joint research of the University of Illinois in the USA and Nanjing University in China.
At the same post and earlier on the page Earth Spin Speed, I explain how the permanent dipole magnet interacts with the electrons current at the tangent of the Inner Mantle sphere to produce Lorentz Force that drives the planet to spin about its axis.
As per Lorentz Force, the angle between the electron current flow and the magnetic field force lines, or gap angle, determines the strength of the force. Since the electrons flow at the Outer Core is always perpendicular to the Axis of Rotation according to Coriolis Effect, then if the angle of magnetic axis that is drawn between the two magnetic poles, and the electrons flow is 90 degree, the Lorentz Force will be at its maximum and the planet spins at a maximum speed. The planet spin speed shall decrease to nil if the magnetic axis makes a 0 gap angle with the electron current flow in the Outer Core; as in the case when the magnetic poles migrate to the level of the equatorial plane.
In 2017 an article was released by Christopher Davies NERC Independent Research Fellow/Lecturer in Geophysics, University of Leeds. The article introduces a magnetic spike that occurred some 3,000 years ago and is located in Jordan and Israel.
Accordingly, the gap angle between the magnetic pole residing in the Levant region and the equatorial plane that is about 27 degree, could have caused the Lorentz Force to get feeble and to the Earth to slow its spin speed to the extent that the Old Testament spoke of the event under the heading; when the Sun stood still and Moon stopped, as I elaborated upon under in the page When Earth Stood Still at this site.
