Thermo-Electrochemical Processes of the Earth’s Degassing Creating Geomagnetic Field and Changing Its Value and Direction (Thermodynamic Approach) ()
ABSTRACT
The currently accepted theory of self-exciting dynamo generating magnetic
field of the Earth and its shortage of energy is critically reviewed. Based on
thermodynamic approach, a new hypothesis of the Earth’s magnetic field, created
by thermo-electrochemical processes of the Earth’s degassing, gravitational
differentiation and their energy, is proposed. The ion-exchange, extraction and
solidification are sources of the ionic currents on solid core and lower mantle
boundaries. These currents are carried by thermo-chemical flows, which create
the primary exciting magnetic field. This field is amplified mostly by
thermoelectricity generated by heat flow thus improving the heat and matter
transport from the Earth’s core and lower mantle to surface. Migration of the
solidification zones and inner core precession are the main causes of changes
of the main magnetic field intensity and reversals of its polarity.
