So we can see how the field is created, but not what compses that field specifically.

Yes, the planets with magnetic fields have a liquid metallic cores that create the magnetic fields.
I was curious about the static electric field because of the observations of the magnetic fields breaking and collapsing - could that phenomenon occur with a static electric field ?
Another musing was with Nuclear Fusion, brought about by Robert Bussard's Polywell concept
http://www.strout.net/info/science/polywell/ could an electrical discharge occur through a magnetic field ? What would the effect of the magnetic field be on the discharge and the field surrounding the discharge ? Could the discharge through the appropriate material result in fusion ?
