Torque on Electric Dipole

电偶极子的力矩

The torque produced on an electric dipole by an electric field can be expressed as a vector product with direction given by the right hand rule.

电场对电偶极子产生的力矩可以表示为一个矢量积，其方向由右手法则确定。

Energy of an Electric Dipole

电偶极子的能
 An electric field produces a torque on a dipole
which tends to take it to its low energy configuration. To rotate it from the low energy state against the field requires work
电场对偶极子产生力矩，使其趋向于低能量状态。要将它从低能量状态逆着电场旋转，需要做功
where the shorter form employs the scalar product.
其中较短的形式使用标量积。
