Neodymium magnets are labeled with a grade, an N rating that signifies a magnet’s level of strength. For example, N ratings range from the lowest strength, N27 to N64, with the most commonly used magnets being a N48 and N64 being theoretically the strongest grade. Essentially, the higher the N rating, the stronger the magnet.

Magnets can vary in type as well. Permanent magnets do not require an energy force because they are powered by natural magnetism in the environment. If you are using magnets for a DIY project, like fridge magnets, then you’ll be using permanent magnets. The most common are neodymium magnets, an alloy of neodymium, iron, and boron, and the second most common are samarium cobalt magnets.
