    "abstract": "We have studied the magnetophoretic particle separation and its nonlinear\nbehavior of ferrofluids in microchannel which is proposed by Furlani. The\nmagnetic gradient force is caused by an bias field and the polarized magnets\nand is found to be spatially uniform in the channel section which can be used\nfor particle selecting or separation. We have derived the equations of\nnonlinear magnetization of magnetic particles which cause the harmonics of\nmagnetophoresis. The Langevin model and generalized Clausius-Mossotti equation\nused show how the normal and longitude anomalous anisotropic effect the\npermeability of ferrofluids, thus the magnetic force. Our analysis demonstrates\nthe viability of using the microchannel system for various bioapplications and\nother characterization of fluid transporting and the time-varying magnetic\nfield can be potentially used for an integrated magnetometer and influences the\nthe viscosity and effective permeability in ferrofluids.",
