Title: What created the Moon's magnetic field?
Post by: thedoc on 31/01/2012 18:02:44
When Neil Armstrong and Buzz Aldrin brought back the first samples of moon rock in 1969, scientists were surprised to see telltale signs in the material that the moon had once had a magnetic field – much like the one we have around the Earth.  Now, another look at one of those 1969 samples has revealed something very unexpected...

Hmm, Didn't the moon smash into the Earth, leaving most of its metal core and taking away a lot of the lighter materials?  Could the magnetic field on this rock be there because the rock was at one time part of the Earth?

The moon was near to Earth, rotations created electromagnetic interaction of metals.
