- Magnetic fields exist in and around galaxies, but the properties of these fields have not been fully explored due to the challenges inherent in observing and modeling them. In this Note, we explore the differences in magnetic field strength of central and satellite galaxies from the magnetohydrodynamic TNG100 simulation. We find that on average, magnetic fields in satellite galaxies are roughly an order of magnitude stronger than those of central galaxies with comparable masses. The difference is greater for satellites that have already approached within $1 R_{200}$ of their host galaxies. These results indicate that magnetic fields in satellite galaxies are amplified by environmental processes as they fall into a host halo.
