| Abstract: | The experimental apparatus for interfacial instability of the magnetic fluid were built up by self-produced magnetic fluid.Changing the exciting current of the electromagnet,the interfacial instability phenomenon of magnetic fluid in magnetic field was researched,and the relationships between the magnetic field and the number,space and height of the three-dimensional spikes were observed.The results show that the number varies directly as the magnetic density,the space is inversely proportional to the magne... |
