Magnetic swimmers are a class of microswimmers, which can be steered and/or propelled by a magnetic field. We proposed a minimal model for independent magnetic swimmers in porous environments, whose orientation aligns passively with an external magnetic field. The porous environment is implemented via coarse-grained interactions with confining walls and circular obstacles. By numerical integration of the respective Langevin equations, we studied the interactions of the swimmers with the environment, as well as their global behavior in a large, confined environment with a magnetic field present. For the specific case of magnetotactic bacteria swimming in sediment-like environments we present a first comparison with experimental data from Magnetospirillum gryphiswaldense swimming in a quasi-2D channel.
