The dynamic process of individual magnetic moment is closely related to the formation or persistence of reverse nucleus in regions where there are usually low anisotropy and complicated stray fields. It is also associated with the propagation of reverse magnetic domain and therefore affects the coercivity of magnets. In this work, we studied the detailed rotation process of individual moment in changing magnetic field. The dependence of the direction of magnetic moment on the direction of anisotropy axis and magnetic field is interestingly complicated. With the angle between the anisotropy axis and magnetic field increasing for different value of the field, the direction of magnetic moment will show three different changing processes, that is, continuously increasing process, sine-like changing process and discontinuously changing process.
