Abstract
The paper considers the reason for the displacement of the magnetic axis relative to the axis of rotation of the Earth for the case of the quartz nature of the dipole magnetic field. A model based on a ring with a current with an uneven distribution of charges along the circumference of the ring is considered. It is shown that the magnetic axis shifts from the axis of rotation towards a greater concentration of charges and, conversely, with a decrease in the concentration of charges. The issue of reducing the number of gravity-oriented quartz crystals in areas of volcanic activity is discussed. The temporal correlation of the beginning of accelerated drift of the Earth's north magnetic pole with the development of volcanic and tectonic activity in the Yellowstone caldera is shown. Attention is drawn to the fact that the Earth's north magnetic pole is shifting towards the geographical pole relative to the geographical coordinates of the Yellowstone caldera.
