The Moon used to have a magnetic field, powered similarly to how the geodynamo powers the magnetism of Earth. Unlike our planet though, the Moon became solid and the magnetic field disappeared.

The magnetic analysis of Chang'e 5 basalt samples by Cai and his colleagues revealed that the Moon had a magnetic field of 2,000 to 4,000 nanoteslas when the Moon was 2 billion years old, or at ...

Benjamin Weiss at MIT has published a Focus piece in the same journal issue outlining the history of research surrounding the moon's magnetic field and the work by the team on this new effort. In ...

Chinese scientists discovered that the moon's magnetic field lasted much longer than expected, persisting into its midlife. By studying tiny rocks brought back by the Chang’e-5 mission, they found the ...

BEIJING -- A new analysis of samples collected by China's Chang'e 5 mission has revealed that the moon possessed a weak yet still running dynamo magnetic field approximately 2 billion years ago.
