But some of its surface rocks exhibit remanent magnetism indicating that there may have been a global magnetic field early in the Moon's history.
但是它的表面岩石展剩磁，表明有可能是一个全球性的磁场早期在月球的历史。

The results show that the effect of remanent polarization is similar to that of electric field and should not be ignored.
结果显示，剩余极化的作用与电场相当，而且其影响一般情况下不能忽略。

By choosing different interwire distances, remanent states, and the exciting field direction, the effects of magnetostatic interaction on resonance frequencies are investigated in detail.
