静电磁场以每米具有的安培单位衡量(A/m)，但是通常以相应的电磁感应单位特斯拉(T)或毫伏特斯拉(mT)表示。
A static magnetic field is measured in units of ampere per metre, (A/m) but is usually expressed in terms of the corresponding magnetic induction measured in units of tesla, (T) or millitesla (mT).
如果伏特这个单位过大，我们就用毫伏或微伏。
Where the volt is too large a unit, we use the millivolt or microvolt.
