  text: We investigate magnetic active matter in confined geometries using both experiments
    with magnetic toy robots, Hexbugs, and simulations of elongated magnetic active
    Brownian particles in circular domains. Standard active particles tend to accumulate
    at boundaries, forming clusters even at relatively low densities. In the presence
    of magnetic interactions, we provide evidence for a  effect that inhibits clustering
    and shifts its onset to higher packing fractions. Moreover, magnetic dipolar interactions
    give rise to collective behaviors such as train-like formations, rotating pairs,
    and rotating clusters.
