Figure 13.

Figure 13

Plot showing the geometry and magnetization directions for a 36 element 3D Halbach array push design (having the same overall volume as that of the benchmark Halbach array of Figure 9). Each sub-magnet is a cube with every side measuring 3.816 cm. The optimization point and resulting force are shown by the black dot and arrow. The elements closest to the optimization point orient to induce a cancellation node like in Figure 11, while the rest focus to extend the magnetic field and its gradient beyond the cancellation node in order to generate a strong push force.
