| 摘 要： | 从磁性粒子的静磁场出发,分析计算了由软、硬磁性两相粒子随机混合的双相磁体中的静磁作用。计算得出:取向的硬磁粒子施加于磁体中软磁相上的静磁场,在磁化方向上的分量为1个正值,它正比于硬磁相的体积分数及其饱和磁化强度,其作用将提高软磁相的矫顽力。 |
| 关 键 词： | 双相永磁 静磁场 静磁作用 矫顽力 |

| Abstract: | The dipolar interaction in a mixed two-phase magnet of soft and hard magnetic particles was analysed. It was deduced that the aligned hard magnetic particles exert a positive average magnetic field on the soft magnetic particles, which enhances the coercive force of the soft magnetic phase. This average field along the magnetization direc-tion of the hard magnetic phase is proportional to the volume fraction of the hard phase in the magnet and its saturation magnetization. |
| Keywords: | two-phase magnet dipolar interaction coercive force magnetic materials |
