The fascinating behavior of ferrofluids in a magnetic field has been intriguing researchers for ages. With the advancement in digital microfluidics, ferrofluid droplets have been extensively used in different applications ranging from biomedical to mechanical systems. Notably, the magnetic field can change the wetting dynamics of sessile FF droplets, leading to a plethora of interesting hydrodynamic phenomena.The active manipulation process with external magnetic excitation is primarily mediated by the deformation of droplets. The deformation of the target droplets originates from the magnetic field-induced interfacial instabilities which in turn lead to the reversible or irreversible shape reconfiguration in a very short span and are found to be useful in several applications.
