In an active system elements draw energy from their surroundings and convert it into mechanical motion. In a dilute fluid environment, active particles can exhibit nonstationary translational and rotational dynamics. When multiple active particles interact, they can produce collective motion including periodic rotations, synchronous swarming, clustering or decoherent and chaotic-like behavior. We incorporate a combined analytical singular perturbation and computational bifurcation methodologies to resolve the complexity of multiple interacting particles under electromagnetic forcing in a stationary fluid.
