WebAfter the yield point is reached, the fluid shears as a fluid, i.e. the incremental shear stress is proportional to the rate of shear (in a Newtonian fluid there is no yield point and stress is directly proportional to shear). Hence the resistance to motion of the fluid can be controlled by adjusting the applied electric field. Webthe synthesized fluid and the magnetic field over the varying range is plotted using the obtained results. Keywords — Magneto-rheological (MR) fluid; Viscosity; Synthesis. I. INTRODUCTION A Magneto-rheological (MR) fluid is a smart material, which responds to the varying magnetic field by changing its state. mental health tatWebAbstract. Magnetorheological (MR) fluids are materials that respond to an applied magnetic field with a change in their rheological properties. Upon application of a magnetic field, MR fluids have a variable yield strength. Altering the strength of the applied magnetic field will control the yield stress of these fluids. mental health taskforce strategy 2016
