Effects of Magnetic Fluid on Magnetic Fluid Damper
Key Engineering Materials, 2012A magnetic fluid damper which based on the principle of second-order buoyancy of magnetic liquid has been presented. During the process of damping, besides the elastic deformation of magnetic liquid adsorbed by permanent magnet, the main ways of energy dissipation are the friction functions, which include the friction between magnets and magnetic ...

Magnetization of two-dimensional magnetic fluids
Journal of Physics: Condensed Matter, 2008The influence of polydispersity on the magnetization of two-dimensional dipolar discs with short-range repulsive interaction is studied by means of Monte Carlo simulations and a high field approximation perturbation theory. Within the framework of perturbation theory an analytical expression is derived for the magnetization of monodisperse and ...

AGGREGATION IN MAGNETIC FLUIDS AND MAGNETIC FLUID COMPOSITES
Chemical Engineering Communications, 1988Many of the properties of magnetic fluids and magnetic fluid composites can be explained by the presence of aggregates of particles. In this paper, the experimental methods by which these properties can be studied are reviewed. Theoretical methods of predicting these properties, and the particle size and magnetic field dependence of the formation of ...

Transactions of the American Institute of Electrical Engineers, 1951
SINCE THE ANNOUNCEMENT of the magnetic fluid by J. Rabinow1 in 1948, several manufacturers have been producing magnetic fluid clutches for use primarily in servomechanisms. Though some manufacturers also have produced designs for breaking service, the author knows of no instance where the magnetic fluid has been used for absorption-dynamometer ...

Transactions of the American Institute of Electrical Engineers, 1948
A new type of magnetic fluid and several classes of new devices utilizing this fluid have been developed at the National Bureau of Standards. One application of this fluid has been in electromagnetic clutches, but the electro-magnetically controlled mixture offers promise for other uses also.

Magnetization Process of Magnetic Fluid
IEEE Translation Journal on Magnetics in Japan, 1985The magnetization curves of magnetic fluids in liquid and frozen states, together with magnetic field cooling effects and particle concentration dependences, are reported. Fluids were frozen in liquid nitrogen under a 3.6 kOe field, and magnetization curves measured as a function of the angle Q (= 0, 45, 90°) between the field during freezing and the ...

Magnetic fractionation of magnetic fluids
Journal of Magnetism and Magnetic Materials, 2000The properties of magnetic nanoparticles in magnetic fluids often exhibit a broad distribution, so in many applications only a small number of particles contribute to the desired magnetic effect. In order to optimize magnetic fluids for applications, preference is given to methods that separate the nanoparticles on the basis of their magnetic ...

Raman spectroscopy in magnetic fluids
Biomolecular Engineering, 2001In this work Raman spectroscopy was used to investigate uncoated magnetic fluids (UMF's) and coated magnetic fluids (CMF's). The coating agents were N-oleoylsarcosine, dodecanoic acid, and ethoxylated polyalcohol. The Raman probe is the hydroxyl (OH) group chemisorbed at the magnetic nanoparticle surface and the measurements were performed in the ...

Research of Computation about Magnetic Fluid under Magnetic Fluid
2011 First International Conference on Instrumentation, Measurement, Computer, Communication and Control, 2011The distribution and shape of magnetic fluid can be influenced by the adding magnetic field. The magnetism of magnetic fluid can be presented by the adding magnetic field. At the same time, the magnetism can influence the distribution of the adding magnetic field.
