A magnet's performance is based on a number of variables including material, grade, size, shape, design, thickness, and the magnetic surface it will attract to. Usually, the magnetic pull is measured off of a steel surface and varying thickness of the steel may increase or decrease the magnetic pull.
WARNING! Please keep these magnets away from the reach of small children and pacemakers. Swallowing magnets can be harmful and will require medical attention.
