Discovered in 1982, neodymium magnets were created through efforts to drive down cost of other permanent magnets. Since invention, the magnets made of neodymium have revolutionized the world of magnetics and their application. Often referred to as sintered neodymium iron boron magnets, or sintered NdFeB, they are part of a group called rare earth magnets. They are made by bonding neodymium magnet powder and binding materials such as rubber, nylon or plastics.

Neodymium magnets are unbelievably strong and sometimes referred to as “super strong magnets” or “super powerful magnets”. The strongest grades are N48, N50 and N52. When made with high grade ingredients, these magnets at a grade of N52 can exert a pull force of nearly 9 lbs. with just a ¼” block. Double that size to ½” and you get a pull force over 32 lbs.! Whether you’ve heard of neodymium magnets or not, you’ve almost certainly used them. They are found in popular consumer products such as iPhones, iPads, other mobile phones, speakers, computer hard drives, hybrid cars and more. These magnets can be purchased pre-fabricated or by custom order. Many of these technologies were not possible until the discovery of this rare earth magnet provided affordability.
