Polymagnets

The concept of multipolar magnets embodies the interaction of magnetic structures with more than two poles. Each magnet is made up of geometric patterns of magnetic elements, so called maxels, that are being imprinted into the magnet surface. These magnetic structures feature designs of magnetic elements varying in polarity, field strength, size, shape, location, and dipole orientation which allows the researchers to produce precision-tailored magnetic fi elds, forces and behaviors when varying the maxel-patterns on the surface of the magnets. The correlated magnetic structures have magnetic fi elds with much higher near-fi eld density and much lower far-field density than conventional magnets which allows a higher precision when utilizing the magnets. The shear and torsional forces can be engineered to deliver performance at levels much greater than conventional single-axis magnets with only two poles. Polymagnets can provide repeatable precision alignment behavior for both rotational and translational positioning. New behaviors include magnets that attach fi rmly in a “locked” position, but when rotated they relax, release, or repel. Behaviors can be combined or layered to create magnetic structures that both attract and repel at the same time. The multipolar magnets could be used for the easy assembly of prefabricated parts of a building or might be used to attach facade elements to an existing building stock without penetrating the exterior walls.
