In this paper we discuss the transport of toroidal magnetic field by a weak meridional flow at the base of the convection zone. We use the differential rotation and meridional flow model developed by Rempel and incorporate feedback of a purely toroidal magnetic field in two ways: directly through the Lorentz force (magnetic tension) and indirectly through quenching of the turbulent viscosity, which affects the parameterized turbulent angular momentum transport in the model. In the case of direct Lorentz force feedback, we find that a meridional flow with an amplitude of around 2 m s~(-1) can transport a magnetic field with a strength of 20-30 kG. Quenching of turbulent viscosity leads to deflection of the meridional flow from the magnetized region and a significant reduction of the transport velocity if the magnetic field is above equipartition strength.
