“…[6][7][8] This exponent decreases under high magnetic fields, and the shear stress tends to become saturated with increasing magnetic field because of magnetization saturation. 9 Chain or column structures are the key phenomena in MR effects, 10,11 and the shear stress of MR fluids comprises the magnetic, friction, and viscous forces of the base oil. [12][13][14] However, the insufficient understanding of MR effects impedes the potential applications of MR fluids.…”

Smart materials of magnetorheological (MR) fluids could be turned from a liquid state into a solid state, which solidification extent or shear strength often increases monotonically with the applied magnetic field. In this study, the shear stress of a dilute MR fluid decreased with increasing applied magnetic field at a constant shear rate. The dynamic shear stress was significantly higher than the stable counterpart at medium magnetic fields. They are ascribed to the slow particle structure transformation. A higher shear rate and particle volume fraction could reduce the transient time and the shear strength difference.

“…When an external magnetic field is applied to a colloidal suspension comprised of magnetic particles (MPs) suspended in a nonmagnetic medium, dipolar interactions are induced within the particles, and various structures are formed in suspension [1][2][3]. The suspension, which is sensitive to applied magnetic fields, is called magnetorheological (MR) fluid or magnetic fluid (MF) [4,5].…”

“…In the researches of magnetorheological fluids and magnetic fluids, the distributions of MPs in suspensions under various magnetic fields have been studied experimentally and theoretically [12][13][14]. When a magnetic field is applied to a colloidal suspension comprised of MPs, dipolar interactions are induced within the particles, and various particle distributions are formed.…”
