because that would be like a magnet sitting on a table spinning around under its own power.

I think we need to include a few electromagnet fields.

possibly generated by the westward spinning outer core
and the eastward spinning inner core , crust and mantle.

dont you?

That is correct. The Earth's magnetic field is generated by the rotation of the conductive core. Movement of the electrons in that core produces the magnetic field. As I understand it the differential rotation of the inner and outer core would be created by the effects of the field from the inner core acting on the outer core. So the inner core would be pushed one way by the magnetic field while the outer core would be pushed the other way. That is like standing on a rotating platform and pushing against a rotating ring around the outside of the one you are standing on. You would rotate one way and the outer ring would rotate the other way.
