>earths magnetic field is powered by the berklin currents between us and the sun.
I have extensively reviewed the EU theory, and have not been convinced about that aspect.
The mainstream representation of a rotating core is horridly inaccurate, once you understand it is a "torriod" flow (river of sorts) trekking at the center mass of moon and earth (if pushed together as one mass - there is a point underneath the surface of earth that would have "zero gravity"). This point correlates with admission and results about "the core".
Dragging around like a rotor in a motor/generator it creates a current also, within earth. Resulting in a field of magnetism.
Apply the theory to actual observation. You will find it applies more accurate than secondary currents from sun, because if the sun's mag field was inducing it would vary much more greatly, and center would align with sun instead of moon.
See what you think- check into it.
