Optimal magnetization for a 36 element Halbach push array with the same volume as the benchmark array of Figure 9. Each element has dimensions of h = 3.33cm, w = 3.33 cm, and t = 5 cm. The factor ‘d’ is the ratio of the push force for this optimal array versus the benchmark 2-element array. The coloring scheme is the same as used in Figure 6. The elements closer to the optimization point orient to induce a cancellation node, while the rest align to extend magnetic field and its gradient beyond the cancellation node to generate a maximal push force.
