About Magnets

Neodymium Magnets
Made of neodymium, these rare earth magnets are the strongest for their size. The nickel-plated finish resists corrosion.
Magnets with poles magnetized through the diameter are often used in rotation sensors.
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.

Multi-Pole Neodymium Magnets
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. 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.

Encased Neodymium Magnets with Unthreaded Hole
A case protects the magnetic material. Steel cases also concentrate and focus the magnetic field. Made of neodymium, these rare earth magnets are the strongest for their size.
