摘要
When the magnetic fluid lays in the magnetic field, interaction effects exist between them. Thus, the precise computation is considered as one of the precise methods of analyzing magnetic fluid in the magnetic field.Comparing with it, the linear computation will bring more error. The more error exists between the decoupled computation and the linear computation, the more saturation magnetization does on the border. Besides, the value of magnetic flux density is bigger when using the decoupled computation than that of linear computation. What’s more,the equal magnetic flux density linear on the border varies slightly in the strong magnetic field when using the two computations. In a weaker magnetic field, the difference is bigger.
