The iron core is molten and moves constantly because of this. Since it is conductive, many electric currents run through the core constantly, and since some of these currents move in a circular pattern, it will produce a magnetic field. Show question Question

What are magnetic fields? (article) Khan Academy

WebYes, but only slightly. Firstly, magnetic fields can superimpose, so the field at any point is the sum of the field due to the Earth and the field due to the moon. However, the moon is rather far away (and has a weak magnetic pole strength), so the magnetic field due to the moon on Earth's surface is nearly negligible (magnetic field also ...
