Abstract
The influence of parallel and perpendicular homogenous magnetic field on the ferrofluid drop formation in dripping regime is studied experimentally. Experimental images are obtained using high-speed video camera with frame rate up to 25,000 fps. The detachment of a drop from the nozzle occurs via the formation of a neck which quickly narrows down until the drop pinches off. The formation of micro-thread from the primary neck is observed before the drop separation. Details of the shape and dynamics of the liquid neck are studied with regard to magnetic field. It is shown that near the detachment point scaled profiles exhibit self-similarity which is not affected by applied magnetic field.
