It is an interesting question, how the moon rocks became magnetised. Because the moon supposingly doesn’t have an iron core to generate a magnetic field as the Earth does. It has long been believed that the Moon formed from ejecta material from an very early collision between Earth and some mystery planet. The material, so they think, only consisted of mantle material from the Earth. Thus, very little iron.
an orb without a magnetic field... wow...
what would Faraday have done there?
