The fact of the axial rotation of the electroconductive dipole planet denotes an induction origin of the ground geomagnetic field.

The chaotic motion of solar corpuscle in the transition zone implies their diffusion separation due to mass difference. Thus, away from the solid Earth the positive high-altitude potential is rapidly rising and the electron concentration of the radiation belts considerably increases with the height. Thus, the transition zone is turned with the proton belt to the Earth that is similar to a massive conductor rotating in the electric field of solar wind protons.

So, the Earth is in peak of the magnetic intensity of protons which cover it as a hemisphere from the alight side (just the magnetic field of solar protons, since there is a motion relativity because of axial rotation of the planet).

Since the Earth is a massive conductor in a magnetic field, so the following actual unavoidably exist in the nature of the Earth: phenomena of geoinduction, geoinduction (Foucault) currents, geomagnetocaloric effect, geomagnetic dipole (complying with direction of the axial rotation of the planet, i.e., directed to the geographic south), earth currents.

At that the asthenosphere and Earth crust with the almost zero ohmic resistance function in the "solar plasma - Earth" induction system as an external closed circuit (for more electrically conductive - by some degrees - deep structures of the Earth).

So, it is obviously impossible to keep the residual electromotive force of induction currents of the planetary interior maintaining the ground geomagnetic field without constant presence of the accumulation of active solar protons above the Arctic - above the negative pole of the Earth.

Since the concentration of protons is above the magnetic south of the planet - Aurora borealis (for the interaction of protons with the geofield results in their layer-by-layer outflow towards magnetic south of the planet followed by formation of the magnetopause, and as the phases of the solar proton motion are solar wind, transition zone, magnetopause, accumulation of protons above the Arctic - Aurora borealis, geomagnetospheric tail), so there is a ground geomagnetic field being in direct proportion to the proton accumulation potential.

The motion of earth current vectors (in the northern geographic hemisphere - clockwise, in the southern hemisphere - counterclockwise, so the rotation of the vectors is 360° per day) shows that all the natural currents of the planet have been conditioned by the geoinduction: Foucault currents of the Earth interior, Earth crust current, atmospheric electricity, ionospheric currents, current discharges between the ionosphere and the solid Earth (whirlwind bearing).

The daily approach of negative pole of the planet with the electromagnetic peak of the transition zone occurring at noon in the western part of the magnetic south meridian, i.e. at 19:00 Greenwich Time (adjusted for aberration of the transition zone protons to the nighttime meridian due to ecliptic motion of the Earth) is optimal to form the concentration of active solar protons above the Arctic and, consequently for a peak of the geofield intensity in a daily rhythm, for a daily peak of the thunderstorm activity of the planet, for initiation of tornado in Florida.

Seasonal changes of geofield intensity (in May - June the geofield is higher than in December) confirm that the accumulation of protons above the Arctic influences the existence of the geofield itself, since the reason of season changes is well-known.

The heat buildup in the planetary interior corresponds to kilowatt-hour what makes it possible for the Earth to radiate 10 ²⁰; kJ heat energy to the space. Such a powerful heat production may be caused only by the geomagnetocaloric effect, for the interior structures are stably stratified, the lava does not contain any radioactive elements; the more so because there is both daily - season rhythmicity of the internal heat buildup and the connection of the volcanism with the solar activity and the cyclicity of volcanism effects in the ages.
