I know this question hasnt been definitively answered yet, but I would like to read any research that anyone can provide.  Ive searched the database at my local library (peer reviewed journal database) but information is not very forthcoming.

Does the friction of liquid metals in the outer core create an electrical field that is turned magnetic by the influence of the Suns magnetic field, or do the created electrostatic charges wrap around the solid inner core through possibly an internal coriolis effect and turn the inner core into a massive electromagnet?  Im sure there are other theories as well.  Im fairly sure that the Curie point only strips natural magnetism, and I know that it is thought that at least the inner core rotates at a slightly faster pace than the exterior portions of the planet, so it seems that there would be some sort of preferred order (latitudinal) of the electric current.  Ive asked two Geo professors in my schools department (one who is a geophysicist) and neither of them seems to know of much new research in that area.  Ive heard of one school (cant remember which...saw it on the Science channel) that is working with liquid metals to attempt a simulation of the outer core and theyve been able to create a weak electric field, but nothing that also involves the inner core as well.

Thank you edward2007.  UW-M was indeed the school that I had seen highlighted, and, fortunately, I have seen the computer models that were referred to on the NASA site.  Unfortunately, my french is very poor, and relegated mostly to "croissant" and "merde", so I was not able to glean any information from there.  I guess what Im looking for are peer reviewed articles describing physical experiments that might be backed up with computer models, but that dont use modeling as their entire basis.
