2013年1月15日 The words, “High Gradient”, means that magnitude of magnetic flux density varies so sharply in a space where magnetic separation happens. Magnetic force acting on a weakly magnetic particle flowing in a fluid is given by Eq. (1), where B is magnitude of magnetic flux density at the particle position [1]. F → m = 1 μ 0 ( κ p - κ f) V p ...

Most of the microparticle magnetic separations take place in aqueous solutions, whose viscosity plays an important role in the dynamics of the microparticle separation processes. Considering that the magnetic force on the magnetic microparticle decreases faster with its linear dimension (as a cube function of its diameter) than its friction coefficient (as a

2006年10月25日 The above-mentioned magnetic colloids are not easy to separate using classical magnets. This is due to a small particle size, at which Brownian motion forces are higher than the exerted magnetic force. To enhance phase separation, various magnetic latexes that may interact with nucleic acids were prepared.

2023年1月11日 The viscosity or ‘troperity’ of the product flow also affects the separation capacity of a magnetic filter. A higher viscosity of this flow will make it more difficult for particles to flow through the product flow and pull towards the magnets. A magnetic separator in operation Magnetic bars used in magnetic separation systems.

2016年1月1日 The magnetic force exerted on a particle depends essentially on the following. 1. The magnetic field strength. 2. The magnetic susceptibility of the mineral. 3. The change in field strength. A greatly simplified expression for the magnetic force on a particle, F M, is given by (17.12) F M = V k s − k f H L d H L d L where. V = particle volume ...

2022年8月18日 The magnetic force in biomagnetic separation processes therefore depends on: how the magnetic field changes spatially (i.e., the magnetic field gradient) the strength of the magnetization of the magnetic beads. When you select the conditions for scaling up your magnetic separation process, it’s important to remember that the
