When the magnetic vector potential is expressed in terms of the magneticfield it, is found to be explicitly non-local in space. This gives support tothe conclusions of Aharonov et al. in a recent comment, that the Aharonov-Bohmeffect may be interpreted as being either due to a local gauge potential orelse due to non-local gauge-invariant fields but not due to localgauge-invariant fields.
