Effects of Magnetic Field Gradient on Particle Distributions of Suspension Comprised of both Magnetic and Nonmagnetic Particles Using Two-Dimensional Monte Carlo Simulations
Functionally graded materials (FGMs) have recently been fabricated under gradient magnetic fields via slip casting, based on the distinct difference in magnetic susceptibility between the components in a suspension comprised of both magnetic particles (MPs) and nonmagnetic particles (NPs). In this work, a physical model of a mixed suspension comprised of both MPs and NPs under a gradient magnetic field is built, base on which the distributions of particles in the suspension under gradient magnetic fields are studied using two-dimensional Monte Carlo simulations, and the effects of magnetic field gradient on the distributions of particles are investigated. The results show that a gradient distribution of MPs is formed along field direction, which is attributed to the translation of MPs. As the magnetic field gradient is increased, the distribution gradient of MPs increases.
