"The Milky Way is Not Just a Refrigerator Magnet"

This is a nice video from NASA on the mapping of the magnetic fields of our galaxy. So not only do we have our Earth's own magnetic field, but there are larger scale magnetic fields generated by the sun and the galaxy.

That was good. Thanks Zapper. I am reminded of Mark Hadley's CP violation, see this. And the top-view spiral reminded me of Minkowski's force-screw, see Space and Time. You take the radial linear electric field lines and combine them with concentric magnetic field lines to draw "electromagnetic field lines". Think spinor.
