First, let’s pay attention to the
picture
that
shows the origin of magnetic forces in an electron. If one places a
body instead of an electron in the centre of the picture, nothing will
change essentially. A body consists of the same charged particles,
energy field of a body interacts with free electrons of the space in
the same way, everything leads to the creation of magnetic forces in
the same way. This process is followed by free electron condensation in
front of the body and rarefaction behind it. As a body energy field is
a sum of energy fields of its atoms, all the body atoms are influenced
by magnetic forces.
Volume density of free electrons is
characterized by the parameter ‘pressure’ P=E/V.
That is why pressure is higher in front of the body that behind it. It
is the reason why charged particles (electrons and protons) flying from
the Sun are captured by the depression zone which proves to be a
bag-trap. It leads to the formation of Earth’s radiation
belts (the Van Allen radiation belts).

It is right to say that Earth’s atoms tend to leave the N
zone for the S zone. The degree of this tendency depends on magnetic
potential difference U which is created between the front and the rare
pints of the moving Earth. It depends not only on it, but also on
magnetic resistance Rì between these points, i. e. on
Earth’s magnetic conductance. However, the thing is that
magnetic conductance is determined by the presence of iron in the
earth’s deep layers. But it is not the end, the temperature
of deep layers is very high, and magnetic conductance of iron stops at
the Curie point (about 800°C). Near-surface layers
don’t contain iron. As a result, only thin upper layers of
magma merging with the mantle are able to conduct.

In
the left figure of the picture the conducting layers are depicted as
a thick semicircle. The dashed semicircle participates as well, but it
is situated on the other side of the Earth. The dashed semicircle
participates as well, but it is situated on the other side of the
Earth. Thus, the conductance area in the interval of a latitude
23-90-23°N is in the alternating conductance mode, while the
area of a
latitude 23°N, 23°S is in the monodirectional one (the
figure on the
right). If the conductance of the first and the second intervals is
constant and identical, the geometric centre of the North Pole will
coincide with the geographic one. Otherwise the unsteady fluctuation of
the coordinates of the geometric North Pole will occur. It is exactly
the thing that we observe in reality.

If global geological processes (earthquakes, volcanic explosions, etc.)
run in the Earth equatorial area, it is followed not only by hurricanes
and storms, but also by motion of the geometrical position of the
magnetic poles. Chaotic precession of the Earth’s
magnetic field is connected with Earth’s volcanic activity
and raw estimation of this precession with the known volcanic changes
definitely proves this point of view.
We can consider our task solved if we
add that mutual correlation of the mentioned processes allows to deal
with a great number of problems of practical importance. In particular,
it is possible to predict volcanic activity in the Earth’s
equatorial areas by the tendency of Earth’s magnetic pole
motion (the geometrical one). For example, it is possible to forecast
volcanic activity on the earth for the nearest future by the known
current tendency of the North Pole motion.
Until recently the Pole was considered to
move northward and north-westward at a speed of 10 km/year. However, in
2001 scientists found out that the speed grew up to 40 km/year and by
the middle of 21st century the pole may reach the territory of Russia
[1]. How is it connected with tectonic activity? In order to answer
this question it is necessary to explain that the effect of magnetic
forces on the Earth’s surface that we observe reflects the
reverse essence of physical changes, i. e. increase of magnetizing
force leads to reduction of magnetic conductance Rì. It means that the
current tendency of the North Pole motion northward and westward leads
to reduction of magnetic conductance on the mentioned vector.
It really threatens seismic disturbances of magnetic conductance
Rì in the south of Russia.
