Precision alignment with magnetic attachment are made possible through correlated magnetics. Multiple magnetic elements or “maxels” simply average out the mis-alignment across the surfaces of multipole Polymagnet™ devices. The result is a programmable alignment tolerance to any level of precision.

Polymagnets have been tested for repeatable precision attachment using a line laser sight, tripod, and coded magnetic attachment device.

Two circular 1.5” Polymagnets each with 101 magnetic elements (maxels) were fitted into levered fixtures (right) and mounted to the tripod head. Field test repeated 100 detach-reattach cycles of the line laser with an average misalignment error of only 0.012 degrees.

Magnets with a single dipole may only partially align at the magnet boundaries due to torque forces in the magnetic field. With Polymagnets, the alignment accuracy is enforced by the number of maxels present in the coded magnet pattern and the spatial frequency at which the aggregate poles alternate. The greater the number of sources, the greater the accuracy.

Polymagnets enable assembly intelligence to be “built-in” to re-deployable office systems, pre-fab construction elements, and more.  Optical systems, rifle scopes, and even microelectromechanical systems (MEMS) can benefit from correlated magnetics.
