Abstract

By dispersing microsized monodisperse polystyrene particles in a ferrofluid, an ideal magneto-rheological model fluid is created. Due to the dipolar interactions of the particles, the hybrid fluid shows solid-like behavior under the shear, i.e., one has to overcome an apparent yield stress before flow sets in. We compare this quantity with theoretical predictions for different magnetic fields and volume fractions of nonmagnetic particles.
