Description

Observations reveal that at the Sun surface, the divergence of what is measured as magnetic field is significantly non-zero. In my paper, I show that what is measured is in fact the magnetic field H, which is different from the divergence-free magnetic induction B. The difference is the magnetization M, which results from the spiral charge movement about the field. However, in the solar interior, the electron thermal velocity is 14 times larger than their escape velocity from the star gravity, and yet 6 times larger than their escape velocity from protons. Therefore electrons escape and come to accumulate in surface layers, where they are responsible for magnetization. This probably occurs in all solar-type stars.
