摘要：
The concentration dependence of the effect a static magnetic field has on the viscosity of aqueous and water-glycerol magnetic liquids based on Fe2.8O4 iron oxide is studied. The viscosity of aqueous and water-glycerol magnetic liquids are found to grow by factors of 2.5 and 20, respectively, as the concentration of magnetic particles and the field intensity grow. The concentration dependence of the magnetic field effect passes through a maximum.
