Lunar magnetism and lunar evolution
月球磁场与月球演化

Several satellites observations demonstrate that the general intensity of lunar magnetism is 1~10 nT(1 nT=10~(-9)T),the largest concentration of strong fields over 100 nT and strong crustal magnetism fields are located in the antipodal region of large impact basins.Remanence intensity of lunar samples are negative related to the abundance of iron,materials which were formed between 3.6~3.8 Ga can gain strong remanent magnetism.The variation of lunar magnetism correlates critical relation of the evolution of moon,giant impact hypothesis is reasonable to explain the variation of lunar magnetism.
