big ring rare earth 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.

Neodymium Magnet Information
Magnet Terminology
The terminology of magnetics is not widely understood. You can find definitions of most terms on our Glossary of Magnet Terminology Page.
Rare Earth
Neodymium magnets are a member of the Rare Earth magnet family and are the most powerful permanent magnets in the world. They are also referred to as NdFeB magnets, or NIB, because they are composed mainly of Neodymium (Nd), Iron (Fe) and Boron (B). They are a relatively new invention and have only recently become affordable for everyday use.

Grades of Neodymium
N35, N38, N42, N38SH…what does it all mean? Neodymium magnets are all graded by the material they are made of. As a very general rule, the higher the grade (the number following the ‘N’), the stronger the magnet. The highest grade of neodymium magnet currently available is N52. Any letter following the grade refers to the temperature rating of the magnet. If there are no letters following the grade, then the magnet is standard temperature neodymium. The temperature ratings are standard (no designation) – M – H – SH – UH – EH. You find the temperature rating of each grade on our Specifications of Neodymium Magnets Page.
