No, it is based in topics such as magnetohydrodynamics. The only link between them is the work of Alfven. No, they are not a part of steady state theory. They would simply work exactly the same way in expanding, contracting, steady state and static universes. Big Bang Cosmology doesn't have to explain sunspots, because they're explained by magnetohydrodynamics. You're beginning to sound like you're trolling, to be honest.
