Interparticle distance control during the aggregation and disaggregation of pairs of magnetic beads: a) Schematic representation of the adjustment of the bead spacing by changing the field angle of applied field from 60° to 120° (indicated in blue in Table S2, Supporting Information). b) Bead translocation along the wave‐like pattern when the external magnetic field rotates from 0° to 180°. c) Change in the interparticle distance between beads was measured for the angle change of 5.81°. The distance is linearly adjusted except for the areas where the beads are in contact with each other (angle from 61.88° to 118.13°). The experimental results and calculations are in good agreement, confirming that the potential well begins to go away from 120°.
