How it works
A polymagnet is a magnet with a printed pole pattern, not a single N/S face. Correlation of those patterns can attract, repel, or hold at a defined gap, then fall off.
In a buffer, that means a force curve you design instead of accepting 1/r² as destiny.
Longevity and temperature are part of the R&D, not a shipping spec.
Spatially coded magnetization makes force a function of alignment, not only gap. You can build a detent, a progressive wall, or a near-zero holding band in one pair.
Spec
