New magnetic moment theory may explain features of solar jets and spicules

TL;DR

This paper proposes a new magnetic moment theory that explains solar jets and spicules by predicting particle behavior opposite to conventional theory, with implications for solar plasma dynamics.

Contribution

It introduces an alternative magnetic moment theory with new energy and magnetic moment results, challenging traditional assumptions and explaining solar phenomena.

Findings

The new theory predicts plasma deceleration in decreasing magnetic fields.

It explains solar jet velocities and heights consistent with recent observations.

The theory's implications extend to Coronal Mass Ejections and Bright Fronts.

Abstract

Current theory states that the magnetic moment of a charged particle is constant, or invariant in a slowly changing magnetic field. It also states that the magnetic flux through a Larmor orbit is constant. The current theory is closely examined, and found to have inconsistencies. An alternative theory is developed with new results for both the energy and magnetic moment of a charged particle. The new theory predicts particle behaviour which is opposite to convention: for example, that a plasma will decelerate as it moves through a decreasing magnetic field. Conversely it will accelerate into an increasing field. The magnetic field of the sun would then act as a restraining influence on solar plasma ejections. The new theory is developed for two forms of the magnetic field: an inverse square law and an exponential. The theoretical results are compared with recent experimental results for the velocity, deceleration, time and heights of solar jets and spicules. The effect on Coronal Mass Ejections and Coronal Bright Fronts is also examined.
