If you've studied anything remotely about electrical phenomina (right hand rules, maxwells equations, amps, volts and EM fields... ie high school physics) and have an interest in astronomy... this is a great presentation @ NASA.

Edit. This could be why Don Scott was invited to NASA

"Magnets are everywhere, but we don’t know how they got here. "

(italics inserted)

The discovery that interstellar space is
magnetic was unexpected and
remarkable.
(yet predicted, theorised and modelled by Nobel Laureatte Hannes Alfven
Then computer simulated by his Alfven's student and NASA Professor Anthony Perratt in 1986 )
But is this just a piece of
cosmic trivia, or is magnetism an
important part of the big picture?
It turns out that many previously
unsolved problems in astronomy
suddenly make sense once one
includes the effects of interstellar
magnetism. As far as life on Earth is
concerned, probably the most crucial
role that magnets play in space is in
the formation of new stars.

take a moment to look at the galaxy image in the pdf, and perrats 1986 magnetic simulations and his animated version. All that is needed is Maxwell's magnetic equations.
