摘要：The microscopic magnetic structure of the ferromagnetic material determines its macroscopic magnetic properties. Therefore, the arrangement of the magnetic domains inside the material affects the magnitude and direction of the magnetic properties that appear externally. In this paper, the degaussing method of ferromagnetic materials based on magnetic domain control is studied. The magnetic domain control principle is studied by analyzing the magnetization process inside the material. The permanent magnet array is used as a strong magnetic source to control the internal magnetic domain by a particular arrangement. Based on the simulation calculation, test is carried out to verify the feasibility of the method. The results show that the use of permanent magnet arrays to control the internal magnetic domains of ferromagnetic materials can effectively reduce the magnetic properties of materials.
