What does magnetic pull force mean?

Every neodymium magnet has a pull force, which tells you exactly how powerful the magnet is. Magnetic pull force is measured in pounds or kilograms, the pull force is the force needed to pull that magnet straight free from a 1/8 inch (3.175 mm) thick steel plate. The pull force also tells you the limit on the holding power of the magnet.

Generally, any magnet with a magnetic pull force above seven pounds (3.175 kg) can pinch your fingers. Strong neodymium magnets can be even more dangerous and should only be handled by experienced individuals.
