摘要
Aharonov-Bohm(AB)effect[1]shows one of surprising aspects of gauge field in quantum electrodynamics(QED).In classical electrodynamics,the gauge potentials A0(t,x),A(t,x)appear in the middle of calculations.However,final results for observables are only expressed by the electromagnetic field E(t,x),B(t,x).
