Neodymium magnets: the super-strong ones

Neodymium magnets are also known as super magnets. A well-deserved name indeed, as they have extraordinary strength even at their smallest size and are among the strongest permanent magnets in the world. The magnetic material of our super-strong magnets is an alloy consisting of neodymium, iron and boron (NdFeB). Neodymium magnets are used for a wide range of applications, from cabinetry, lighting systems, plastics technology and packaging materials to the construction of models. We keep an inventory of over 40 million magnets and can fulfil even large orders directly from our warehouse at any time. With our 20 years of experience, we are your specialist for neodymium magnets. The advantages of neodymium magnets at a glance:
  • Super-strong adhesive force
  • Suitable for small spaces (miniaturisation)
  • Even the smallest neodymium magnets are just as strong as larger common ferrite magnets

Neodymium super magnets: Strongest in the world

Many of you might ask yourself: Why is a neodymium magnet a super magnet? And: Wouldn’t a cheaper ferrite magnet be sufficient for my project? The special NdFeB combination (neodymium-iron-boron) results in a high adhesive force even in small magnets. It is no coincidence that neodymium magnets are also known as high-performance magnets. Compared to NdFeB magnets, ferrite magnets of the same volume are much weaker. That is why neodymium magnets are known as super magnets.

We recommend buying super magnets if you need a small, lightweight magnet or a large, extra-strong magnet. In the assortment of our online shop, you can find the perfect magnet for your project, from mini magnets to ultra-strong neodymium magnets. Neodymium magnets are slightly more expensive than ordinary ferrite magnets because neodymium is a rare earth metal. Hence, super magnets are also known as rare earth magnets.

We recommend ferrite magnets when:
  • used outdoors
  • exposed to temperatures over 80 °C
For outdoor use we also carry some rubberised super magnets. Also in our web shop: Self-adhesive neodymium magnets e. g. as clasps for paper and cardboard articles, for name tags and arts & crafts.

Neodymium magnet facts

  • The neodymium-iron-boron alloy (NdFeB) was developed in the early 1980s. It is used to make neodymium magnets which are still the strongest permanent magnets on the market today.
  • Many neodymium magnets can be used up to 80 degrees. If they are heated above this temperature, they lose their magnetic properties. In our supermagnete assortment, you will also find high-temperature block magnets. These neodymium magnets can withstand temperatures of up to 150 degrees.
  • The most common coating for neodymium magnets contains nickel. At our online shop, you can also buy magnets with other coatings, such as chrome, copper or gold. Additional information can be found on the FAQ page "Which magnet coatings are there?".

Tips for handling neodymium magnets

  • The specified adhesive force is always measured at right angles to the surface. Because of the displacement force, neodymium magnets tolerate much less strain on a wall than they do on the ceiling. You can find further information on these topics on our FAQ page "What is the difference between adhesive force and displacement force/shear force?".
  • The stronger a magnet, the greater the potential for injury. Even smaller neodymium magnets can cause injuries if handled carelessly. Therefore, familiarise yourself with the safety information for neodymium magnets before use to avoid dangers and injuries.
  • Do not let neodymium magnets collide, otherwise the coating will come off or the magnets will shatter. This has nothing to do with inferior quality but is a typical characteristic of neodymium magnets. Learn more about it on our FAQ page "Why does the coating of my magnets chip?".
  • Neodymium magnets are not intended for outdoor use as they will rust over time and lose their magnetisation. Outside, use ferrite magnets instead because they won’t rust. For more information go to our FAQ page "Can I use magnets outdoors as well?".
  • You can use thin silicone discs to protect surfaces from being scratched by the magnets.

Additional information about neodymium magnets

Our practical adhesive force tool is free of charge and allows you to calculate the adhesive force for a variety of neodymium magnets. Also, make sure to check our FAQ page, where we put together facts and figures about neodymium magnets for your information. There you can find out, for example, what the specifications N42, N45 or N52 mean or learn more about the recommended safety distances between magnets and other items.
