The possibility of locomotion of a pair of disjoint spherical microbeads suspended in fluid is investigated experimentally. The beads interact magnetically and their nonreciprocal relative movements are coordinated using external uniform magnetic field. Locomotion is studied and demonstrated for cyclic swirling movements of the beads which mimics behavior often observed in bacterial swarms.
