Title: Magnetic fields in moving-mesh cosmological simulations

In this talk, I will introduce the results of a suite of uniformly sampled ideal MHD cosmological simulations performed with the moving-mesh code Arepo. I will mostly focus on the properties of magnetic fields in these simulations at redshift zero and how they are affected by the inclusion of baryon physics processes that are thought to be relevant for galaxy formation. In particular, I will show that the simulations are able to capture the amplification of tiny seed fields present in the early Universe to the B field values observed nowadays in galaxy and galaxy clusters. Finally, I will discuss the effects of varying the magnetic seed field intensity on the properties of the simulated galaxy population.
