Large Magnetoviscous Effect in Magnetic and Non Magnetic Ferrodispersion

Abstract:

Under the application of magnetic field, magnetic fluids exhibits magnetoviscous effect. We have observed large magneto viscous effects by dispersing magnetic and non-magnetic anisotropic micron size magnetic particles in a ferrofluid , the mixture is known as ferrodispersion. For both the samples density and volume concentrations of large particles are kept identical i.e. 25, 50 and 75 vol %. It is observed that for 25% and 50% vol. concentration the magnetoviscous effect for both the samples is comparable, however for 75% concentration the field dependent viscosity of non-magnetic bentonite anisotropic particles are much larger than its counterpart. This shows even non magnetic particle can also enhance the magneto viscous effect. Results can be useful to develop a novel kind of bidispersed magnetorheological fluids to increase its commercial applicability.
