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).
皮安表是安培表的一个门类，其实质上是静电计中安培表功能的延续。
A picoammeter is an ammeter built along the lines of the ammeter function of an electrometer.
目的在于避开磁场概念 ，只从静电场理论的角度讨论电磁问题 ，通过对运动电荷相互作用力的分析 ，运用简单的几何关系和库仑定律 ，重新诠释了安培力定律。
By analyzing the interaction of the locomotor charges and using simple geometrical relationship and the Coulombs law, we provide a new interpretation for the Ampere force law.
由于静电计、安培计或皮安计的输入端压降小于1mV，这两个二极管不会导通。
Since the voltage burden of the electrometer ammeter or picoammeter is less than 1mV, the diodes won't conduct.
