Lunar magnetism refers to the study of the magnetic fields present on the moon. Unlike Earth, the moon does not have a global magnetic field, but localized magnetic fields have been detected in various regions of the lunar surface. These fields are thought to have been produced by ancient volcanic activity and interactions with the solar wind. Research into lunar magnetism aims to better understand the origins and nature of these magnetic fields, as well as their potential effects on the moon's crust and surface features. This research can provide valuable insights into the moon's geological history and the impact of space weather on planetary bodies.
