Resolution of the Mansuripur Paradox

Daniel J. Cross

摘要:

当用洛伦兹力的三矢量公式分析磁偶极子与点电荷的相互作用时,会导致一个明显的悖论。具体地说,偶极子在某些坐标系中受到扭矩,而在另一些坐标系中不受扭矩。我们表明,当分析根据协变4-向量制定的悖论消失。在某些框架中产生的力矩与静止框架中力矩的时空分量相联系,从而产生“隐藏”动量。

英文摘要:

The interaction of a magnetic dipole with a point charge leads to an apparent paradox when analyzed using the 3-vector formulation of the Lorentz force. Specifically, the dipole is subject to a torque in some frames and not in others. We show that when analyzed according to the covariant 4-vector formulation the paradox disappears. The torque that arises in certain frames is connected to the time-space components of the torque in the rest frame, giving rise to "hidden" momentum.
