i wonder what studying magnetized lunar rocks might disclose?
Mystery of Moon’s Lost Magnetism Solved?

excerpt...
“When Apollo astronauts brought back samples of moon rocks from their lunar landing missions in the 1960s and ‘70s, some of them shocked scientists by being magnetic. That means that individual rocks might have a magnetic north and south pole and a small magnetic field of their own.
This can happen to rocks with the right minerals inside them, if they cool in the presence of a magnetic field. The problem is, scientists had no idea that the moon had ever had a magnetic field, and were at a loss to explain how that might have happened.”
