Neodymium rectangular magnets, also called block magnets, offer outstanding performance pulling forces from 1.4lb to 260lb. These magnets can be used in everything from model building and crafting to motors and industrial manufacturing. Rectangular magnets can be fixed in place using adhesive or can be pushed into slots or grooves in wood or plastic. Neodymium magnets attract each other with almost twice the force that they use to attract steel objects. Many new packaging designs use neodymium magnets cleverly hidden behind laminations of cardboard to provide invisible closing mechanisms for folders, gift boxes, name badges, and even greeting cards!
