Abstract
In this paper, we demonstrate virtual channels defined by “walls” of magnetic fields, which can be used to construct a dynamically reconfigurable network of flowing magnetic beads. Magnetized by an external magnet, nickel structures generate magnetic fields that can `hold' and, therefore, guide/trap magnetic particles. In this study, we exhibit S- and Y-shaped virtual channels which steer magnetic beads smoothly. Comparison on the relation of the bead's speed versus magnetic flux density between channels with different radii of bending curvature or with different widths is also shown. Lastly, a switchable channel implemented with a bistable mechanism is used to demonstrate the passing and blocking of a bead, proving the feasibility of a dynamically reconfigurable network.
