On a possible alignment of elementary spin vectors in astronomical bodies

A. Dinculescu1

Abstract

Under the hypothesis that astronomical bodies tend to align the spin vectors of their internal magnetic dipoles parallel to the rotation axis in order to increase the entropy by decreasing the rotational energy, we derived the magnetic fields of the known magnetic bodies in the Solar system. The calculated values, which span over 17 orders of magnitude, agree fairly well with the measured ones, despite the fact that elementary dipoles responsible for the magnetic fields that predominate in terrestrial bodies differ from those predominant in the Jovian planets, and both types differ from those predominant in the Sun.
