Rare Earth Neodymium (Neo) Magnets

Neodymium magnets (also known as “NdFeb”, “NIB” or “Neo” magnets) are the strongest permanent magnets commercially available today, and the most powerful class of rare-earth magnets. Made from an alloy of neodymium, iron and boron, neo magnets have the highest magnetic properties and energy product of all the permanent magnet materials. Due to their high magnetic strength and relatively low-cost, neodymium magnets are the preferred choice for countless consumer, commercial, industrial and technical applications.

NdFeB Magnets in Assorted Shapes, Sizes & Premium Grades

Our extensive inventory of neodymium magnets includes discs, blocks, bars, rings, rods, and more in a broad range of sizes, finishes and premium grades (from N30 to N52). Not all our magnets are displayed on this website. If you can’t find the magnets you’re looking for contact us today, and our staff will ensure that you find the best magnets for your application.

*Note: The approximate pull info listed is for reference only. These values are calculated assuming the magnet will be attached to a flat, ground 1/2" thick mild steel plate. Coatings, rust, rough surfaces, and certain environmental conditions can significantly reduce the pull force. Please be sure to test the actual pull in your actual application. For critical applications, it is suggested that the pull be de-rated by a factor of 2 or more, depending on the severity of a potential failure.

Neodymium Magnets Features & Characteristics

  • What is a neodymium magnet? Neodymium magnets are strong permanent magnets, and part of the Rare-Earth magnet family. They are also referred to as “NdFeB”, “Neo” or “NIB” magnets, as they are composed mainly of Neodymium (Nd), Iron (Fe) and Boron (B).

  • Why are neodymium magnets so strong? Neodymium magnets are considered strong because they have a high saturation magnetization and resist demagnetization. Although they are more costly than ceramic magnets, strong neodymium magnets pack a powerful punch! Because they are so strong, smaller NdFeB magnets can achieve the same effect as larger magnets made from other materials, leading to lower overall costs for many applications as the entire device can shrink.

  • How long do neodymium magnets last? Neodymium magnets will likely lose less than approximately 1% of their flux density over a 10-year period if their physical properties remain intact, and they are not subjected to demagnetizing influences (such as high-temperatures, opposing magnetic fields, radiation etc.).

  • What are the main characteristics of neodymium magnets? Neodymium magnets are far less subject to cracking & chipping and less costly than other rare-earth magnetic materials such as Samarium Cobalt, and are available in a wide variety of shapes, sizes and premium grades.

  • What neodymium magnet grades are available? We carry a large inventory of licensed, neodymium magnets in premium grades; N30, N32, N33, N35, N38, N39, N40, N42, N44, N45, N48, N50, and N52 which is the highest grade available in today’s market.

  • What is a rare-earth magnet? Rare-earth magnets are the strongest type of permanent magnets available today, and produce significantly stronger magnetic fields. They are known as Rare Earth magnets because a significant proportion of their chemical composition is based on the Rare Earth, or Lanthanide, part of the periodic table of elements.

  • What safety precautions should be taken into consideration when working with neodymium magnets? Neodymium magnets are hard, fairly brittle, and high in magnetic strength. They can snap together with great force, so please ensure that all personnel handling these magnets are aware to handle them carefully in order to avoid injuries. In particular, large Neodymium magnets must be handled with extreme care – please plan ahead for safe handling procedures! They can also chip or break if dropped or if snapped together, so please take special care when handling these powerful magnets!
