Neodymium Magnets - The Strongest Permanent Magnets Available Today!

Neodymium magnets (also known as “NdFeb”, “Neo” or “NIB” magnets), are permanent magnets made from neodymium, iron & boron magnetic alloys. Part of the rare-earth magnet family, neodymium magnets have the highest magnetic properties of all permanent magnets. Due to their high magnetic strength (even in small areas) and versatility, they are often the preferred choice for  many consumer, commercial, industrial and technical applications. carries a large inventory of licensed neodymium magnets, discs, blocks/bars (rectangular & square), rings & rods in a wide range of sizes, shapes, premium grades and finishes. Not all of our neodymium magnets are shown on this website so please contact us if you don't see what you are looking for.

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 NdFeB magnets or NIB, as they are composed mainly of Neodymium (ND), Iron (Fe) and Boron (B). (top)
  • Why are neodymium magnets so strong? Neodymium magnets are considered strong because they resist demagnetization and have a high saturation magnetization. Although neodymium magnets are more costly than ceramic magnets, these super strong magnets pack a powerful punch! With neodymium magnets, you can use a smaller sized magnet to achieve the same objective. This can potentially lead to a lower overall cost, as the size of the entire device can shrink. (top)
  • How long do neodymium magnets last? Neodymium magnets will likely lose less than approximately 1% of their flux density over a 100-year period if their physical properties remain intact. (top)
  • 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 material such as Samarium Cobalt ("SmCo"). They are however, more sensitive to temperature. For applications where this is critical, SmCo may be the better choice, since its magnetic properties are very stable at elevated temperatures. (top)
  • What grades & shapes are available for neodymium magnets? Grades 30-52 of Neodymium magnets are available in disc, rectangle, square and rod shapes, and can be custom manufactured to meet your specialty requirements. Just let us know what you are looking for by sending us a Special Request(top)
  • What are some common applications for neodymium magnets? Neodymium Magnets are typically used in audio equipment (microphones, headphones, and loudspeakers) hard disk drives, pumps, bearings, MRI scanners, electric vehicles, wind generators, high performance motors, actuators, magnetic therapy, anti-lock braking systems, levitation devices, door latches, model making, arts & crafts, home improvement (DIY-fixing furniture, hanging pictures etc.) POP displays & more. (top)
  • What are the best temperatures to use for neodymium magnets?  Neodymium magnets should not be used in temperatures above 130° C(240° F) without careful magnetic circuit design. Please contact us to discuss your application with our engineers if you plan on using these magnets above this temperature. (top)
  • Do neodymium magnets require surface treatments? Neodymium magnets that are not protected with a surface coating (such as plating) may rust in humid conditions. (top)
  • What common bonding applications are used for neodymium magnets? Neodymium magnets are often assembled into products using “super glues” such as Loctite 325. As with all bonding applications, please ensure that bonding surfaces are clean and dry (prior to bonding) for best results. (top)
  • What is a permanent magnet? Permanent magnets represent the majority of magnetic materials available today. A permanent magnet is made from ferromagnetic materials, which have magnetic fields that do not turn on and off like electromagnets. We carry a large inventory of permanent magnets; neodymium, alnico, ceramic (ferrite) and samarium cobalt, in a wide variety of shapes, sizes and grades. (top)
  • What is a rare-earth magnet? Rare-earth magnets are the strongest type of permanent magnets available today, and produce significantly stronger magnetic fields than ceramic (ferrite) or alnico magnets. There are two types of rare-earth magnets; neodymium and samarium cobalt, both of which are available for on-line purchase. Click here to learn more information about magnetic materials. (top)
  • How are magnets rated? Magnets are typically rated by their residual induction, coercive force & maximum energy product. This refers to the maximum strength that the magnetic material can be magnetized to. Click here for more details (section 4.0). (top)
  • What does "approximate pull Info" mean? The approximate pull info listed for Neodymium magnets are for reference only. These values are calculated under the assumption that 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. (top)
  • 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. They can also chip or break if dropped or if snapped together, so please take special care when handling these powerful magnets! (top)
