a) Continuous twist of the magnetic microparticles after pulse field alignment and 2 min. of relaxation. b) Analysis of the corresponding shear rate dependence of apparent viscosity during continuous particle twist. ηm denotes the apparent viscosity at the initial phase of particle twist, η5 denotes the apparent viscosity at a shear rate of 0.05 rad/s. The inset shows the a magnetic dipole, the component of detection along the z-axis and the rotation in the reverse twisting field.
