Droplet actuation is an essential mechanism for droplet-based microfluidic systems. On-demand electromagnetic actuation is used in a ferrofluid-based microfluidic system for water droplet displacement. Electropermanent magnets (EPMs) are used to induce 50 mT magnetic fields in a ferrofluid filled microchannel with gradients up to 6.4 × 10<sup>4</sup> kA/m<sup>2</sup>. Short 50 µs current pulses activate the electropermanent magnets and generate negative magnetophoretic forces that range from 10 ...[more]
