Magnetic interaction between astrophysical objects can play an important role and produce electromagnetic radiation in various systems, ranging from planet-moon and star-planet systems to binary compact objects. We extend our previous numerical study of an ideal magnetized plasma flowing past a conducting sphere to the case where the sphere is magnetized. Such a flow generates magnetic disturbances and produces a drag force on the sphere. We examine the drag coefficient as a function of the strength and orientation of the conductor's internal magnetic field relative to the background magnetic field. We find that a strong internal magnetic field that is aligned with the background field significantly enhances the drag coefficient compared to the unmagnetized case; this enhancement is related to the increased magnetic flux that connects the conductor and the open, external field region. We also explore how the drag coefficient changes as the flow transitions from the sub-Alfv\'enic to the super-Alfv\'enic regime. Our results suggest that magnetic interaction may play a larger role in orbital evolution of some binary systems than previously expected.
