Abstract :
This article investigates the effect of magnetic field on the viscosity of Fe3O4-water magnetic nanofluid
experimentally. Experiments were done in the volume fraction range 0 to 1 vol% and the temperature ranges
from 25 to 45 °C. The results showed that the viscosity increased with increasing of nanoparticle volume
fractions and decreased with temperature enhancement with or without of magnetic field. Also, it is observed
that the viscosity of the magnetic nanofluid increases with enhancement of magnetic field strength. Thus,
magnetic field is a basic factor that influences the viscosity of the magnetic nanofluids and magnetic
nanofluid flow can be controlled by applying a magnetic field.
