Lunar magmatism created magnetism

Nature Geoscience, Published online: 14 April 2026; doi:10.1038/s41561-026-01955-w The mechanism that generated strong magnetic fields on the Moon remains unclear. Lunar samples that record high field strengths combined with heat flux modelling suggest a link between eruption of high-titanium basalts and dynamo generation.
