The magnetic field of the Moon is very weak in comparison to that of the Earth; the major difference is the Moon does not have a dipolar magnetic field currently (as would be generated by a geodynamo in its core), so that the magnetization present is varied (see picture) and its origin is almost entirely crustal in … See more In the Space Odyssey series by Arthur C.

Websinks, and the differential motions create a magnetic field. On the Moon, the whole body cooled much faster than Earth (because the Moon is smaller), so the core also cooled, and probably solidified. Motions fast enough to generate a magnetic field do not occur today inside the Moon's core. In Class Divide the class into cooperative teams of 4 ... 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 ...
