The key techniques of the research on magnetic fluid traveling wave pumps are the produc-tion of traveling wave magnetic fields,the design of pump structures,the dynamic characteristics of magnetic fluid, and so on.According to the generation forms of traveling wave magnetic fields, a line magnetic fluid traveling wave pump is designed and the coupling of a travelling magnetic field with a force field in the magnetic fluid is analyzed by a decoupling method. Experiment results indicate that the magnetic fluid flux has a direct relation with the magnetic field under the effect of traveling wave magnetic field.The bigger the magnetic field is, the more the flux is, when the structure of the magnetic fluid travellig pump and the saturation magnetization of magnetic fluid are constant. The volumes of the magnetic fluid from the travelling wave pump increase from 1.9 ml to 3.1 ml, when the magnetic field intensity increases from 25 900 A/m to 40 000 A/m.In addition,the change rate of the magnetic fluid decreases with the increase of the magnetic field due to the effect of magnetic field on magnetic fluid viscosity. The bigger the saturation magnetization of the magnetic fluid is, the more the flux is.
