摘要

我们证明，例如，定义由带电粒子和磁场形成的系统的线性动量的z分量是可能的，当且仅当磁场在沿z轴的平移下不变。类似地，可以定义由带电粒子和磁场形成的系统的角动量的z分量，当且仅当磁场在绕z轴旋转下不变。

The linear and the angular momentum stored in a distribution of charges in a magnetic field

We show that it is possible to define, e.g., the z-component of the linear momentum of the system formed by a charged particle and a magnetic field if and only if the magnetic field is invariant under translations along the z-axis. Similarly, it is possible to define the z-component of the angular momentum of the system formed by a charged particle and a magnetic field if and only if the magnetic field is invariant under rotations about the z-axis.
