Polymagnet® Demo Kit lets product designers and engineers explore and experiment with magnetic functions made possible via next-gen magnetic circuitry. Surface of Polymagnets is encoded with pattern of multiple north and south poles, and polarity pattern can be designed to achieve desired result/function: super-strong attachment, shallow field, magnetic spring, magnetic latch, and repelling up close or at distance. Kits contain various Polymagnet samples and Hi-Res magnetic viewing film.
