About Magnets

Multi-Pole Neodymium Magnets with Unthreaded Hole
Many small poles give these nickel-plated magnets shallower, more concentrated magnetic fields that hold especially well on thin material. To prevent accidental attachment, they won't attract until they're close to the material. Slide onto a rod or use a bolt or screw to install. Also known as Polymagnets®.
Warning: Maximum pull ratings are based on direct contact with rust-free and unpainted iron plate. Variations in material condition will significantly reduce these ratings. Do not use for lifting over people.

Alnico Rotor Magnets
These magnets have a central hole for mounting on shafts. Use them in motors and turbine generators. Alnico magnets aren't as strong as rare earth magnets, but they withstand the highest temperatures. Magnets come with a keeper that covers the poles to preserve the strength of the magnet and protect it from attracting metal during storage.
Warning: Maximum pull ratings are based on direct contact with rust-free and unpainted iron plate. Variations in material condition will significantly reduce these ratings. Do not use for lifting over people.
