Recent experiments have shown that floating ferromagnetic beads, under the influence of an oscillating background magnetic field, can move along a liquid-air interface in a sustained periodic locomotion [Lumay et al., Soft Matter, 2013, 9, 2420]. Dynamic activity arises from a periodically induced dipole-dipole repulsion between the beads acting in concert with capillary attraction. We investigate analytically and numerically the stability and dynamics of this magnetocapillary swimming, and… Expand
Optimal motion of triangular magnetocapillary swimmers.
TLDR
The obtained maxima of the swimmer speed are interpreted by the optimal frequency centered around the characteristic relaxation time of a spherical particle, which shows a sharp dependence of the average center-of-mass speed on the frequency of the time-dependent external magnetic field. Expand

Remote control of self-assembled microswimmers
TLDR
It is shown that a magnetocapillary-driven self-assembly, composed of three soft ferromagnetic beads, is able to swim along a liquid-air interface when powered by an external magnetic field, and that trajectories can be fully controlled, opening ways to explore low Reynolds number swimming. Expand

How a nearby interface can provide the symmetry breaking necessary for propulsion is discussed, and an overview of recent experiments illustrates how forces at the interface can be used to generate locomotion. Expand
Direct Measurement of Capillary Attraction between Floating Disks.
TLDR
This work uses an applied magnetic force to perform direct measurements of the capillary attraction force between centimetric disks floating at an air-water interface, and describes the dependence of the attraction force on the disk mass, diameter, and relative spacing, and develops a scaling law.

Regimes of motion of magnetocapillary swimmers
TLDR
Modifying the ratio of surface tension and magnetic forces allows to study the swimmer propagation in the regime of significantly lower frequencies mainly defined by the strength of the magnetocapillary potential. Expand

Symmetry breaking in a few-body system with magnetocapillary interactions.
TLDR
A Dejarguin-Landau-Verwey-Overbeek (DLVO)-like potential is proposed, i.e., an interaction potential with a primary and a secondary minimum, capturing the main physical features of the magnetocapillary interaction, which is relevant for self-assembly. Expand
Viscosity control of the dynamic self-assembly in ferromagnetic suspensions.
TLDR
It is argued that the transition from snakes to asters is governed by the viscosity of the suspending liquid where less viscous liquids favor snakes and more viscous, asters, and the results illustrate that the Viscosity can be used to control the outcome of the dynamic self-assembly in magnetic colloidal suspensions.
