since the earth and moon have a combined center of gravity, and given the fact that they haven't figured out everthing about the whys and wherefors of the earth's magnetic field, have they figured in the moon's effect on the magnetic field?

@atoms55,

What is "nichol"? Is it a new element?

Probably. Why do you ask?

What's a compass? Why not just use your GPS. Wink

because I was wondering if anyone knows the specific ways the moon's gravitational field affects the Earth's magnetic field and the iron core; it seems as though some very interesting things would occur.

The magnetic field of the Moon is very small in comparison to the Earth's. It has very little discernible effect on Earth's magnetic field, and even less of an effect on the Earth's core.

The gravitational barycenter of the Earth/Moon system probably has a much larger effect on the Earth's core and mantle as it moves through the interior.
