Hm, let’s see, the Moon has been slowly receeding from Earth, Earth has an active magnetic field, the Moon would have spent lots of orbit time moving through the magnetic field of the Earth ... well, they are paid to guess I suppose.

I put a bolt on a magnet for days... and the bolt became magnetic too, for a while at least.

How long would that take to wear off from the moon?
