Abstract

Does a collection of magnetically driven rotors necessarily rotate in the same direction as its individual members? We show that rotors driven by a rotating magnetic field self-assemble into clusters whose collective rotation can oppose the self-rotation of every rotor within them. The reversal arises from competition between rotation-translation coupling and dipolar interactions, which favor opposite directions of collective rotation. Their balance varies with system size and driving frequency, producing a transition between the two handed states, while hydrodynamic interactions shift the transition boundary. Collective handedness can thus emerge opposite to the field-imposed single-rotor rotation without reversing the external field, and can be tuned through system size and driving frequency.
