Alternating Magnetic Field Responses of Magnetic Fluid Drop Adsorbed to a Small Permanent Magnet

Abstract:

Experimental studies of the behavior of magnetic fluid drop under the effect of an external alternating magnetic field were performed using a high speed digital video camera system. A small permanent magnet was immersed in magnetic fluid drop, and it was fixed with an aluminum bar. The surface of magnetic fluid responded to the external magnetic field sensitively. The free surface of the magnetic fluid drop responded to the external alternating field in elongation and contraction along the direction of the field. The capillary magnetic fluid jet was produced at the certain external magnetic field condition.
