Simulation results and 3D magnetic flux density norm patterns of the magnetic system: (a) The maximum magnetic force occurs at the distance of 2 cm; (b) at the distance of 2.5 cm, distribution starts; (c, d) a nonconcentrated magnetic force is observed at the distances of 3 and 3.5 cm; (e) at the distance of 6 cm, magnetic fluxes are combined into a circular pattern, and the magnetic force significantly decreases. (f) The red line represents densities at the distances of 2, 2.5, and 3 cm; orange and yellow ones correspond to the distances of 5 and 6 cm, respectively; light and dark blue represent the lowest magnetic flux density at every level.
