Active galactic nuclei (AGN) found at the centers of clusters of
galaxies are a possible source for weak cluster-wide magnetic
fields. To evaluate this scenario, we present 3D adaptive mesh refinement
MHD simulations of a cool-core cluster that include injection of
kinetic, thermal, and magnetic energy via an AGN-powered jet.
Using the MHD solver in FLASH 3,
we compare several sub-resolution approaches
that link the estimated accretion rate as measured on
the simulation mesh to the accretion rate onto the central black hole
and the resulting feedback. We examine the effects
of magnetized outflows on the accretion history of the black hole
and discuss the ability of these models to magnetize the cluster medium.
