Have we finally solved mystery of magnetic moon rocks?

Why are some rocks on the moon highly magnetic?

Scientists may have solved the mystery of why the moon shows ancient signs of magnetism although it has no magnetic field today. An impact, such as from a large asteroid, could have generated a cloud of ionized particles that briefly enveloped the moon and amplified its weak magnetic field.

Have we finally solved mystery of magnetic moon rocks?

Simulations show how effects of asteroid impact could amplify the early Moon’s weak magnetic field.

The Moon’s Mysterious Magnetic Rocks Might Have A Cataclysmic Explanation

Scientists from MIT have proposed a bold new theory to illuminate unexplained findings across the decades.

The moon doesn't have a magnetic field, so why does it have magnetic rocks?

A new simulation suggests a massive asteroid impact may have briefly supercharged the moon's magnetic field, leaving behind magnetized rocks that still carry its signature.

Why are some rocks on the moon highly magnetic? Scientists may have an answer

Where did the moon's magnetism go? Scientists have puzzled over this question for decades, ever since orbiting spacecraft picked up signs of a high magnetic field in lunar surface rocks. The moon itself has no inherent magnetism today.

Researchers at MIT have proposed a novel hypothesis to explain why some lunar rocks are highly magnetic, despite the Moon currently having no magnetic field of its own. According to their findings, the magnetic anomalies could be due to a rare combination of a weak ancient dynamo in the Moon’s core and a powerful meteorite impact that temporarily boosted that field via a plasma storm....
