A circulating current can be induced in the Fermi sea by displacing a scatterer or more generally by integrating a quantum pump into a closed circuit. The induced current may have either the same or the opposite sense with respect to the ``pushing'' direction of the pump. We work out explicit expressions for the associated geometric conductance using the Kubo-Dirac monopole picture and illuminate the connection with the theory of adiabatic passage in multiple path geometry.
