摘要

In this work, the influence of the sweep rates of applied magnetic fields on the agglomeration of magnetic particles in the magnetic fluid film are reported. It was observed that a smaller column agglomerated by magnetic particles results at a higher sweep rate as compared with that at a lower sweep rate. Besides, the magnetic moment per volume inside a column decreases rapidly when the sweep rate is raised from 0 to 15 Oe/s, and almost remains constant as the sweep rate exceeds 20 Oe/s. This variation implies that the packing of magnetic particles inside a column depends on the sweep rate. Thus, the sweep rate is a crucial variable determining the internal structure of columns.
