Apollo 12 Magnetometer: Measurement of a Steady Magnetic Field on the Surface of the Moon

The Apollo 12 magnetometer has measured a steady magnetic field of 36 ± 5 gammas on the lunar surface. Surface gradient measurements and data from a lunar orbiting satellite indicate that this steady field is localized rather than global in its extent. These data suggest that the source is a large,...

Summary:The Apollo 12 magnetometer has measured a steady magnetic field of 36 ± 5 gammas on the lunar surface. Surface gradient measurements and data from a lunar orbiting satellite indicate that this steady field is localized rather than global in its extent. These data suggest that the source is a large, magnetized body which acquired a field during an epoch in which the inducing field was much stronger than any that presently exists at the moon.
