论文摘要
概述了磁场梯度对具有线性磁敏感性的流体的影响。结果表明，在溶液中，磁场梯度梯度力和溶液中的磁场梯度梯度力和不可压缩流体的浓度梯度力量等效。磁场梯度和浓度梯度力分别是开尔文力和korteweg-helmholtz力密度的近似值。得出了磁引起对流的出现标准。审查了磁诱导的对流作用的实验性工作。
An overview of the effect of a magnetic field gradient on fluids with linear magnetic susceptibilities is given. It is shown that two commonly encountered expressions, the magnetic field gradient force and the concentration gradient force for paramagnetic species in solution are equivalent for incompressible fluids. The magnetic field gradient and concentration gradient forces are approximations of the Kelvin force and Korteweg-Helmholtz force densities, respectively. The criterion for the appearance of magnetically induced convection is derived. Experimental work in which magnetically induced convection plays a role is reviewed.
