The effect of inter-particle hydrodynamic and magnetic interactions in a magnetorheological fluid [PDF]

open access: yes, 2022
A magnetorheological fluid, which consists of magnetic particles suspended in a viscous fluid, flows freely with well-dispersed particles in a the absence of a magnetic field, but particle aggregation results in flow cessation when a field is applied. The mechanism of dynamical arrest is examined by analysing interactions between magnetic particles in ...

Stopping of Charged Particles in a Magnetized Classical Plasma [PDF]

open access: yesPhys. Rev. E, vol.58, No.2 (1998), 1998
The analytical and numerical investigations of the energy loss rate of the test particle in a magnetized electron plasma are developed on the basis of the Vlasov-Poisson equations, and the main results are presented. The Larmor rotation of a test particle in a magnetic field is taken into account. The analysis is based on the assumption that the energy

Quantifying and dispensing of magnetic particles in a self-assembled magnetic particle array

open access: yesJournal of Magnetism and Magnetic Materials, 2021
We develop a low-cost, mass-production process for creating rod-shaped glass-coated magnetic particles consisting of a magnetic metal core and glass shell structure. We investigate their magnetic properties by analyzing their optical absorbance in suspension as a function of the orientation of a 1 mT magnetic field. From the response we derive that the

The chain length of anisotropic paramagnetic particles in a rotating field [PDF]

open access: yes, 2020
In this article, the maximal length of a chain of paramagnetic particles with magnetic anisotropy in a rotating magnetic field is studied. The theory of paramagnetic particle chains usually assumes that the particles are magnetically isotropic and do not rotate in a rotating field. In experiments it is seen that spherical paramagnetic particles rotate,
