More About Flexible Magnets: Flexible materials offer a uniquely desirable combination of properties at lower cost than other magnet materials. The flexibility and machinability of these materials allow manufacturing techniques not possible with rigid or brittle materials. Flexible magnet material is used in a variety of applications from labeling, holding, door gaskets, and signs, to micromotors and CRT focusing. Practical uses include crafts, toys, games, magnetic signs, displays, production control (or visual aid) systems, warehouse shelf labeling, movable markers, advertising premiums, magnetic business cards, architectural planning layouts and more.
