Abstract

The viscosity of magnetic fluids was studied using a capillary viscometer of our own design and the method of oscillating volume of magnetic fluid in a magnetic field. Samples were tested on various carrier liquids—kerosene and polyethylsiloxane—with a volume concentration φ of the solid phase from 19 to 2.5%. The developed setup based on a capillary viscometer allows viscosity measurements in the magnetic field strength range from 20 to 350 kA/m. Measurements based on oscillations of the system occur in the range from 150 to 900 kA/m. It was experimentally established that the results obtained using these methods agree with each other, which allows us to conclude that both methods provide an identical estimate of the viscosity of a magnetic fluid in a magnetic field.
