Research of Magnetic Fluid under the Orthogonal Stationary Magnetic Field

The nonlinear characteristic is the one of essential characteristics about the magnetic fluid. The orthogonal stationary magnetic field is caused by the mutual orthogonal DC. According to the grads of magnetic field in the area filled with magnetic fluid, the magnetic density of magnetic fluid changes with the grads of magnetic field. With the increasing magnitude of DC, the magnetic density of magnetic fluid can be increased. Error of the measured voltage wll be increased as the volume of the changing rate of DC increasing.
