TL;DR

This paper proposes a synthesis model for the Sun's fast dynamo mechanism, involving two symmetrically placed toroidal structures in the tachocline that generate the solar magnetic field through charge entrapping and currents.

Contribution

It introduces a novel model of the solar dynamo involving charge-entrapping tori with superconductor-like properties and a 3D solar circuit capable of magnetic field reversal.

Findings

Tori trap surplus charge with 11-year cycle sign change.

Tori generate intense magnetic fields via currents.

Model suggests a superconductor-like behavior at tachocline.

Abstract

We provide a synthesis model demonstrating the "fast dynamo" action of the Sun. The latter is essentially accomplished via two toroidal structures presumably formed in the tachocline and placed symmetrically with respect to the equatorial plane. The two tori are characterized by several prominent key-properties as follows: First, in each "Torus" a surplus charge is entrapped for the time period of an 11-year sunspot cycle; for the next cycle the charge changes sign. Second, the net charge of Torus, moving with the solar rotational speed (U), generates a huge toroidal current which, in turn, builds up an intense poloidal magnetic field. Third, each Torus is placed at a specific distance from the Radiative Zone, so that the U of an entrapped charge carrier equals the local propagation velocity for an electromagnetic disturbance (v). Thus, two Torus electrons satisfy the condition that the repulsive electrostatic force equals the attractive magnetic force caused from the two elementary currents. Fourth, the surplus charge steadily increases; electrons are systematically attracted inwards or repealed outwards via the poloidal field. The charges remain without any "Debye shielding" action in the Torus-core region, while they demonstrate a "Debye anti-shielding effect" closer to the Radiative Zone. Thus, the Torus charge "moves" with zero resistivity and rotational speed U; the Torus core region behaves like a gigantic superconductor at the extremely high temperatures of tachocline. Fifth, the tori move equatorward drifting on a surface being an ellipsoid by revolution on which the condition U=v is satisfied. Moreover, we present a preliminary 3D solar circuit with the ability to reverse the magnetic field in each 22-year cycle. Finally, we discuss many longstanding unresolved questions in the context of the proposed model.
