Effect of Orientation Degree on Magnetic Homogeneity of Nd-Fe-B Magnets

Abstract:

Magnetic homogeneity and flux distribution in Nd Fe B magnets have been studied using a statistic method. The results show that the distribution of magnetic flux is affected by various random factors such as composition, orientational field, and magnetic flux density. The statistic results conform well to a normal Gaussian distribution. Moreover, the main factor affecting magnetic homogeneity is the orientation degree of the easy axis of the powders.
