There have been proposed hypotheses as to how the Moon could have developed a core dynamo. For instance, a 2022 analysis ...

A combination of a dynamo-generated magnetic field and massive impacts could explain the highly magnetized rocks in some ...

The Moon today has no inherent magnetism, making the discovery of magnetized rocks on the surface a big problem. Where did ...

Where did the moon's magnetism go? Scientists have puzzled over this question for decades, ever since orbiting spacecraft ...

Using computer simulations, the researchers uncovered a scenario in which an ancient asteroid impact briefly amplified that field, just long enough for nearby rocks to capture and record its 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 ...

A massive impact may have sent a shockwave through the moon, jolting rocks just as a magnetic spike peaked and leaving behind ...

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

The iron’s sloshing motion, in a process called a dynamo, creates and sustains Earth’s magnetic field. Given the crucial role the planet’s magnetic field plays in guiding navigators and ...
