Magnetic Analysis of Ferromagnetic Substance in the Process of Rotation Demagnetization

Abstract

To solve the problem that is the poor demagnetizing effect and stability issues by the way of demagnetization in the one-dimensional space, a new degaussing method was studied in this paper, based on the analysis of magnetic moment angle distribution during the degaussing deal to iron material. Through the magnetization process analysis to iron material in the rotating magnetic field, the theory has some merits such as good degaussing effect and stability to the iron material after degaussing deal in two-dimensional space. The rotation degaussing enhancing the stability of material magnetic field is tested effectively, comparing to degaussing at one-dimensional space.
