Research of Computation about Magnetic Fluid under Magnetic Fluid

The distribution and shape of magnetic fluid can be influenced by the adding magnetic field. The magnetism of magnetic fluid can be presented by the adding magnetic field. At the same time, the magnetism can influence the distribution of the adding magnetic field. There is the decoupled question between the magnetic field and force under the adding magnetic field. When the magnetic field is stronger, the influence can be neglected that the magnetism of magnetic fluid affects the distribution of the adding magnetic field. The smaller is the saturation magnetization of magnetic fluid, the smaller is the error of decoupled computation and linear computation.
