Latch Polymagnets

This design note goes into detail about the latch Polymagnet function, which repel until they are pushed toward each other to a defined distance, at which point they attract and latch closed.

Latch Polymagnets are available for purchase in the Polymagnet Catalog in a range of sizes and configurations.

Below is a video demonstration and an animation of the Latch Polymagnet function.


Latch Polymagnets repel until they are pushed toward each other to a defined distance, at which point they attract and latch closed.

Latch Polymagnets are produced in matched pairs and will repel each other at a distance beyond their defined attachment distance. When they are closer than their defined attachment distance, they will attract and attach together.

Latch Polymagnets must be constrained and centered with respect to each other to perform properly.
