Comparison of recovery dependence on magnetic moment between the optimized alternating array (2.0 mm width) and the optimized Halbach array (1.0 mm width) showing a decrease in magnetic moment needed to achieve 100% recovery. For very low magnetic moments, where only the cells close to the surface are captured, the alternating array outperforms the Halbach array due to its higher gradient close to the surface.
