Analytic Origin of Advection of Magnetic Fields by Diffusivity Gradients

Published 17 Sep 2013 in physics.plasm-ph and astro-ph.SR | (1309.4398v1)

Abstract: We derive the advection of magnetic fields due to gradients in magnetic diffusivity, starting from the magnetic induction equation. We discuss physical examples, and compare our results to those in the literature. Our induction and diffusion equations may be useful in solar dynamo studies, and for space and laboratory plasmas.
