Possible origin of lunar magnetism

Naturevolume 257pages295296 (1975) | Download Citation



ANY model of the origin of lunar magnetism needs to explain two principal observations1. One is the magnitude of the stable natural remanent magnetisation (NRM) carried by the returned lunar samples, which is far too large to have been acquired in fields comparable with those found at present in the vicinity of the Moon. The other is the presence of remanent fields at the lunar surface, which imply source regions of tens or hundreds of kilometres of homogeneous magnetisation, primarily in the highlands.
