应变波通过铁磁性杆件时，由于压磁效应，可以激发出不均匀的磁流。
When strain waves pass through a ferromagnetic bar, owing to piezomagnetic effect, a nonuniform magnetic current will be stimulated by the strain wave simultaneously.

微破裂可能产生了偶电层，在破裂过程中向外辐射，产生了LF频段的磁信号，UL F磁信号则主要由压磁效应产生。
The generation of the magnetic signals at LF band may be caused by the emission of electrons from the breaking crystals in the rocks, whereas that of ULF band by the piezomagnetic effect.

在空间上，压磁、感磁等机制引起的震磁效应主要分布在震中附近的有限区域内，震级越大，展布范围也越大。
Spatially , seismomagnetic effect caused by piezomagnetism and induced magnetism. is mainly distributed in the limited areas near epicenters , the bigger of the magnitude , the wider of the range.

压磁效应
铁磁性材料受到机械力的作用时，它的内部产生应变，导致导磁率发生变化，产生压磁效应。磁材料被磁化时，如果受到限制而不能伸缩，内部会产生应力。同样在外部施加力也会产生应力。当铁磁材料因磁化而引起伸缩产生应力时，其内部必然存在磁弹性能量。
