The characteristics of ferrofluids depend on magnetic field gradient. An aggregate effect is one of the most interesting subjects. Aggregations are formed in the ferrofluid whether there is a magnetic field or not. Therefore, they have an effect on rheological characteristics such as shear viscosity, normal stress effects and so on. In this research the Stokes Dynamics simulations are made for aggregate structure of ferrofluids under the strong magnetic field. A result obtained is that a metastable area exists in the aggregation of ferrofluids.
