标题： On the origin of the minimal coupling rule, and on the possiblity of observing a classical, "Aharonov-Bohm-like" angular momentum

摘要： 最小耦合规则是从兰道在存在经典电磁场的情况下对带电粒子的相对论不变经典作用量“推导”出来的。 然后提出了实验，以观察包含螺线管的经典“不均匀”带电环所产生的电磁角动量。 这些经典的宏观实验在精神上与阿哈罗诺夫和玻姆在量子水平上提出的实验相似。 显示英文摘要

摘要： The minimal coupling rule is "derived" starting from Landau's relativistically invariant classical action for a charge in the presence of classical electromagnetic fields. Experiments are then proposed to see the resulting electromagnetic angular momentum of a classical, "lumpy" charged ring enclosing a solenoid. These classical, macroscopic experiments are similar in spirit to those proposed by Aharonov and Bohm at the quantum level.
