This work demonstrates the possibility of using a magnetic repulsion force to reduce the volume of the residue that remains on a surface after detachment of a ferrofluid droplet. This technique provides a means for controlling the detachment residue by controlling the spatial strength of the magnetic field used for droplet detachment. The experimental technique developed in this work can help us to improve our understanding of the underlying physics of droplet adhesion to a surface and the mechanics of residue formation during droplet detachment.
