Boosting the Magnetic Field of a Torus-shaped Conductive Fluid via Poloidal Flow

抄録

Researchers have struggled to understand the mechanism underlying the formation of celestial magnetic fields. Currently, the generation of axisymmetric and poloidal magnetic fields can be solved by complex convection arguments. There are also claims of simple convection, but these claims are not purely simple axisymmetric convection claims. This paper addresses a truly simple axisymmetric poloidal convection and magnetic field. To calculate the electrical components, this paper introduces a theory that separates the vector potential into inductance and current in a relational formula. The reason is to consider the mutual influence between distant circuits in terms of mutual inductance. The change in current is subsequently calculated from the change in inductance. It is solved as an eigenvalue problem via numerical calculation. Using this method, a simple axisymmetric poloidal magnetic field can be generated from axisymmetric poloidal convection. Another reason is the nature of the mutual inductance and Lenz's law, which reflects the effect of current changes on other electric circuits. This approach is intended to eliminate the concern that magnetic field growth will be impaired by convection that carries currents away. These concepts are novel, and we believe that these findings will contribute to further elucidating the formation mechanism of celestial magnetic fields and plasma reactor research. However, some issues in this paper remain unresolved.
