The Spring-Latch Combo Polymagnets function like a Spring until rotated 180°, when the force switches to attract and they latch together. The demo comes complete with two Polymagnets, red knobs, brass post and plastic end caps.



The Polymagnet pair used in this demo is part # 1002299; a 0.010" steel shunt is bonded to this pair to increase adhesion to the plastic end caps.
