Control theory is employed to formulate the problem of controllability of two microparticles in fluids via magnetic field. We demonstrate that a uniform external magnetic field of varying direction and magnitude provides complete local state controllability of two particles over a magnetized substrate. We propose that such an approach may improve manipulation and assembly of microparticles in fluids.
