System and method for tailoring polarity transitions of magnetic structures
A system and method for tailoring a polarity transition of a magnetic structure is provided that involves printing one or more reinforcing maxels alongside one side or both sides of a polarity transition boundary between a first polarity region of the magnetic structure having a first polarity and a second polarity region of the magnetic structure having a second polarity, where printing reinforcing maxels alongside the polarity transition boundary improves the magnetic field characteristics of the polarity transition.
1. A magnetic structure having multiple poles, comprising:
a first polarity region magnetized to have a first polarity;
a second polarity region magnetized to have a second polarity; and
a polarity transition boundary, at least one of said first polarity region or said second polarity region having at least one reinforcing maxel that was printed alongside said polarity transition boundary.
2. The magnetic structure of claim 1 , wherein said at least one reinforcing maxel changes magnetic field characteristics across a polarity transition.
3. The magnetic structure of claim 2 , wherein the polarity transition has a steeper slope than the slope of the polarity transition of the magnetic structure without said at least one reinforcing maxel.
4. The magnetic structure of claim 1 , wherein said at least one reinforcing maxel enables more efficient use of a magnetizable material.
5. The magnetic structure of claim 1 , wherein said at least one reinforcing maxel produces higher torque.
6. The magnetic structure of claim 1 , wherein said first polarity region has at least one reinforcing maxel having said first polarity.
7. The magnetic structure of claim 6 , wherein said second polarity region has at least one reinforcing maxel having said second polarity.
8. The magnetic structure of claim 1 , wherein said at least one reinforcing maxel comprises a round maxel.
9. The magnetic structure of claim 1 , wherein said at least one reinforcing maxel comprises an elongated maxel.

15. The magnetic structure of claim 1 , wherein said at least one reinforcing maxel comprises maxels having different amplitudes.
16. The magnetic structure of claim 1 , wherein said magnetic structure was produced by printing a maxel having said first polarity onto a side of a single pole magnet having said second polarity.
17. The magnetic structure of claim 1 , wherein at least one dimension of the surface of a magnetizable material upon which said at least one reinforcing maxel was printed is smaller than at least one dimension of the aperture of the print head used to print the at least one reinforcing maxel.
18. The magnetic structure of claim 1 , wherein said magnetic structure was produced by printing a maxel with a magnetizable material backing layer beneath and at least proximate to the magnetizable material upon which said at least one reinforcing maxel was printed.
19. The magnetic structure of claim 18 , wherein said magnetizable material backing layer comprises at least one of a conductive ferromagnetic material, a non-conductive ferromagnetic material, or a conductive non-ferromagnetic material.
