Increasing the stiffness of magnetorheological fluid contained in a fabric by applying a magnetic field has considerable potential in engineering applications. In this work, we have used a spacer (three dimensional) fabric to contain the magnetorheological fluid and then investigated the changes in the stiffness value of the composite material ...

Preferred flow paths are defined by the shape and arrangement of pores, and a characterization of this pore fabric forms the basis for prediction of fluid flow directions. Magnetic pore fabrics (MPFs), that is, magnetic anisotropy measurements on ferrofluid-impregnated samples, are a promising and fast way to characterize the pore fabric of ...

Two different shapes of spherical- and flake-like soft-magnetic carbonyl iron (CI) microparticles were dispersed in silicone oil to prepare magnetorheological (MR) fluids. The magnetic-field dependent rheological behaviors of the MR fluids were scrutinized focusing on their shape effect. Saturation magnetization of the flake-shaped CI was …

First use of Alnico magnets. Composed of Aluminum, Nickel and Cobalt, JBL was the industry leader in introducing this strong permanent high power alloy in professional speaker systems. Alnico magnets produce magnetic field strength at their poles as high as 1500 gauss (0.15 tesla), or about 3000 times the strength of Earth's magnetic field.

Magnetic pore fabrics (MPFs) provide a fast and efficient tool for pore fabric characterization. The samples' pore space is impregnated with ferrofluid, followed by measuring the anisotropy of magnetic susceptibility (AMS) (Pfleiderer & Halls, 1990), and thus only connected pores, which contribute to flow, are targeted by MPFs. MPFs can be ...

In the absence of a magnetic field, they behave like a Newtonian fluid with a low viscosity of 0.1 to 1.0 Pa·s [2], [3]; once the magnetic field is applied, a rapid and reversible transition from a free-flowing state to a solid state can be observed, which can be quantitatively described by the viscosity change and the viscosity in the field ...

The term 'ferrofluid' is a portmanteau of ferromagnetic and fluid and is used to describe a fluid that is strongly magnetized by a magnetic field. This occurs because the fluid is composed of tiny magnetic particles, up to 100 times smaller than the wavelength of visible light. The most common minerals used in making these magnetic ...

Hence, they are not ideal for assessing pore fabrics in fluid flow studies (Almqvist et al., 2011). Anisotropy of magnetic susceptibility (AMS) of ferrofluid-impregnated samples has been proposed as a fast and efficient method to assess the average 3-D structure of connected pores (Parés et al., 2016; Pfleiderer & Halls, 1990, 1994).
