With modern telescopes we can see magnetic fields throughout the universe, in our solar system, in and around galaxies and in interstellar space. Given that magnetic fields do not exist without moving charge i.e. a electric current.Why is it that;
a) Astrophysics only ever talk about magnetic fields and never seem to mention the electric currents that must produce them
b) Why these electric currents/magnetic fields when they obviously exist throughout the universe are not considered in celestial mechanics.
