Two questions: 1) Can the massive black holes at the core of galaxies have magnetic fields? 2) All stars stream plasma into space continually, much of which simply cools down and becomes cold interstellar plasma (as well as gas). Wouldn't you expect electrical and magnetic fields to develop in this cold plasma, much as they do in the hot plasma of the stars? What I am trying to get at here is that cold plasma is largely invisible, hence there may be larger currents and fields than we are aware of.
