Magnetic field distribution in the microchannel, calculated using COMSOL. (a) Magnetic field distribution of three parallel magnets with a spacer. (b) Magnetic flux densities at different locations across the channel (lines 1, 2, and 3) at the height of 200 μm in the microchannel. (c) Magnetic field distribution of permanent magnets without spacers. (d) Plots of magnetic flux densities at the top and bottom of the microchannel.
