Simulations of magnetic micropatterns. A The magnetic flux density (Bnorm) in a log scale as simulated in COMSOL at 2 μm above a permalloy bar magnet with arrows indicating the magnetic force direction, showing strong magnetic attraction to the edges. B The magnetic flux density (By) in a log scale as simulated in COMSOL for the YZ plane at x = 0 µm. C-E The magnetic attraction force magnitude at 2 µm above the magnet (D) along the Y axis at x = 0 µm and (E) along the X axis at Y = 80 µm (20 µm from the edges)
