Abstract We discuss the effect of Aharonov-Bohm magnetic flux on the time reversal symmetric properties of mesoscopic metallic ring systems. It is usually believed that AB flux causes time reversal symmetry breaking. We analysis the case of mesoscopic persistent currents and find out that AB flux does not break time resversal symmetry. Our arguments are supported by general theory of mesoscopic persistent currents.
