By means of mechanical properties test, the relationship among particle size,electric field,magnetic field ,electromagnetic field and shear ratio on the Ni/TiO2/Urea core-shell particles electrorheological fluid properties analyses. It is found that with increasing particle size, the property of electrorheological fluid decreased, and with increasing shear ratio the property of electrorheological fluid increased for same composition ER. At same time, the smaller of particle size, the higher of ER properties, but there is a critical value for shear ratio, the properties of ER is near value for same composition ER fluid. In magnetic field, the properties of ER showed a contrary result, the smaller of particle size, the lower of ER properties,and electromagnetic field make the properties increase.
