Many writers write scary scenarios about the movement of the magnetic poles. The actual point where magnetic compasses point directly towards the centre of the earth is not where the strength of the of the earth’s magnetic field lies.

The magnetic ovals show how the earth is deflecting the ions streaming out from the sun. The points where magnetic dip needles are perpendicular to the surface exert little on the aurora borealis and aurora australis. The actual north magnetic pole is 2500 miles under the northern shore of Greenland. Likewise the south magnetic pole is 2500 miles under central Antarctica very near the geographic south pole. The two auroral ovals have not moved much over the past century. The auroral ovals demonstrate Mother Earth flexing her muscles.
All the theories on the cause of earth magnetism are inadequate. We do not know what is generating planetary magnetism.
