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.

Have we finally solved mystery of magnetic moon rocks? - WorldNL Magazine

NASA's Apollo missions brought back moon rock samples for scientists to study. We've learned a great deal over the ensuing decades, but one enduring mystery remains. Many of those lunar samples show signs of exposure to strong magnetic fields comparable to Earth's, yet the Moon doesn't have such a field today. So, how did the moon rocks get their magnetism? There have been many attempts to explain this anomaly. The latest comes from MIT scientis…
