About Magnets

Ceramic Magnets with Unthreaded Hole
Ceramic magnets resist demagnetization better than other magnets and are an economical choice. Slide onto a rod or use a bolt or screw to install.
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.

Ferrite Cores
Often used as inductors and transformers in electrical circuits, these cores generate a magnetic hold when magnet wire (sold separately) is wrapped over them and energized. Remove the electric current and the cores lose their magnetism.
Encased Ceramic Magnets with Unthreaded Hole
A case protects the magnetic material. Steel cases also concentrate and focus the magnetic field. Ceramic magnets resist demagnetization better than other magnets and are an economical choice.
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 Magnets with Mounting Plate
To add a magnetic surface anywhere, install the mounting plate, then screw on the magnet.
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.
