【 摘 要 】

It is difficult to accurately analyze and master the magnetic properties of irregular objects with complex internal magnetic structure. In this paper, the multi-magnetic dipole model of magnetic target is established. The magnetic field data around the magnetic target are measured by magnetometer array, and the position of the multi-magnetic dipole is searched by genetic algorithm, and the fitting error is detected at the same time. The experimental results show that the magnetic field model established by this method has high accuracy and the errors of magnetic field and magnetic moment are less than 5%. This method is beneficial to the research and engineering application of magnetic properties of objects.
