The lattice Boltzmann method (LBM) is a versatile numerical technique for simulating complex fluid dynamical systems and beyond. Here, we first describe an extension of the LBM to flow systems in external magnetic fields. The model is verified numerically with several benchmarks and shown to correctly predict signal changes caused by in-flow effects in a simple flow experiment.
