In this study, a Lagrange point-based manipulation strategy is proposed to generate a micropumping effect using a permanent magnetic actuator. First, the effects of different actuator parameters, such as the angular position, the diameter of the permanent magnets, and the distance between the permanent magnets, on the Lagrange points generated in the microchannel and the magnetic force are numerically investigated. Moreover, the interaction between magnetic force and magnetic nanofluid is examined through flow analyses. Then, a real actuator setup working with magnetic nanofluid is designed and manufactured in accordance with the results of numerical analyses. Following, proof-of-concept experiments are conducted for the parameters utilized in the numerical analyses, varying actuator speeds, and the volumetric concentration of the magnetic nanofluid. According to the observations from the proof-of-concept experiments, the proposed actuator design can successfully pump the magnetic nanofluid by trapping it at the stable Lagrange point. Moreover, a flow rate range of 8.6-34.3 mu l/min is reached for actuator speeds of 3-12 rpm.
