Abstract: The magnetic field generated by the rotation of the magnetic source is a dynamic magnetic field with a certain frequency, which has strong ability to resist interference, and it can not only improve communication quality and system performance but also enhance information security and spectrum utilization efficiency, which hold significant application value in fields such as resource exploration and ocean exploration. In order to make use of the rotating magnetic for ocean exploration, the model of the rotating magnetic source (RMS) is modeled with the rotation axis as the z-axis in paper, and we analyze the spatial magnetic field distribution of the stationary magnetic source and the moving magnetic source, respectively. Besides, the variation of magnetic field amplitude with distance is analyzed, and the results show that the three-axis magnetic component is a sinusoidal signal with a certain frequency, and the triaxial magnetic components generated by the magnetic moment components mp and mf are symmetrically distributed about B = 0, and the static magnetic field generated by the vertical magnetic moment component ml is superimposed with the sinusoidal signals generated by the magnetic moment components mp and mf, which causes the amplitude to shift. The study is of great significance which provide a theoretical foundation for the ocean exploration.
