  text: When tiny soft ferromagnetic particles are placed along a liquid interface
    and exposed to a vertical magnetic field, the balance between capillary attraction
    and magnetic repulsion leads to self-organization into well-defined patterns.
    Here, we demonstrate experimentally that precessing magnetic fields induce metachronal
    waves on the periphery of these assemblies, similar to the ones observed in ciliates
    and some arthropods. The outermost layer of particles behaves like an array of
    cilia or legs whose sequential movement causes a net and controllable locomotion.
    This bioinspired many-particle swimming strategy is effective even at low Reynolds
    number, using only spatially uniform fields to generate the waves.
