I'm studying Dynamo Theory, and have just a few questions. Today's theory says that currents in the molten outer core of the Earth give rise to magnetic fields. Now it would seem that the theory does not mean "molten iron currents", since together that is an electrically neutral substance, but rather "electrical currents", since it is known that a moving electrical charge generates a magnetic field. If this is true, then what induced the electrical currents in Earth's core? Am I grasping the main scientific concept behind field generation, or is there something else I'm missing? Thanks!
