Studies of the rheological characteristics of water-, hydrocarbon- and diester-based magnetic fluids were carried out with and without a magnetic field. Experimental studies were made by means of the concentric-cylinder-type rotating viscometer which is operated within a strong magnetic field to clarify the effects of magnetic field, temperature and shear rate on the rheological characteristics of the magnetic fluids. The magnetic fluids are Newtonian in the case of non magnetic field. In the case of applied magnetic field, the flow curve for hydrocarbon-based fluid is still Newtonian. On the other hand, the water-based and diester-based fluids show pseudoplastic behaviour. Empirical formulae are obtained on the theoretical consideration of the laminar flow between rotating concentric cylinders.
