摘要
在磁技术应用中，对永磁材料的主要磁性参数的研究及测量已成为人们关注的问题之一．本文提出通过测量磁场从而确定永磁体磁矩的一种简便方法，并就测量所涉及的有关问题作了讨论．
In the application of PM technology,the research and measurement of the main coefficients of PM materials have become one of the concerned problems. In this paper a simplified method is presented to measure PM msgnctic moment by measuring magnetic field and a discussion is given on the problems involved in measurement.
