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.

Discover suitable neodymium magnets with the magnet finder

Are you looking for neodymium magnets with specific characteristics? With the magnet finder, you can quickly find the right magnets. In the magnet finder, you will see all neodymium magnets listed on a single page. Various filter options are available so you can narrow down the large selection of magnets. Filter by desired adhesive force, size, shape, design, magnetisation, coating and many other options. With just a few clicks, you will find exactly the right magnets with the characteristics you want.

Neodymium magnet shapes

At the supermagnete online shop, you will find the most popular shapes of neodymium magnets:
  • Disc magnets
  • Rod magnets
  • Block magnets
  • Cube magnets
  • Sphere magnets
  • Ring magnets
  • Cone magnets

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.

Calculating the adhesive force of neodymium magnets with the adhesive force tool

With our practical adhesive force tool, you can perform adhesive force calculations for a variety of neodymium magnets free of charge. You can use it to easily determine the adhesive force of a magnet for your planned application.
In the tool, first select whether you want to carry out a calculation for a magnet on an iron plate or for a magnet adhering to another magnet. Next, you can select a neodymium magnet from our assortment (with the exception of cubes or blocks) and specify the distance between the magnet and the iron plate/other magnet. In addition to a predefined distance, you can also have the tool calculate ten different distances by selecting the 'variable' option.

Questions about neodymium magnets

How long do neodymium magnets stay magnetic?

Under normal conditions, neodymium magnets remain magnetic almost indefinitely. However, some factors do cause neodymium magnets to lose their magnetic force. They include:
  • Heat
  • Vibration
  • Corrosion
  • Other strong magnetic fields
For more detailed information, please visit our FAQ page about loss of adhesive force.

How do you attach neodymium magnets?

Neodymium magnets stick to metal surfaces, that much is clear. But what do you do if there is no such surface? We will show you three options.

Option 1: Fasten them with screws
If the intended mounting surface is made of wood, for example, then screw-on neodymium magnets are an ideal solution.
Option 2: Glue them on
Utilise self-adhesive neodymium magnets or use UHU MAX REPAIR to glue conventional neodymium magnets to your intended mounting surface.
Option 3: Create a suitable surface
A suitable holding surface will allow magnets to adhere. In our supermagnete assortment, you will find various surfaces for magnets, including metal strips and iron sheets.

In our FAQ section, we have gathered plenty of facts and figures pertaining to other commonly asked questions about neodymium magnets. You can, for example, find out what the designations N42, N45 or N52 mean. Or, learn more about the recommended safety distances between magnets and other objects. It's worth taking a look!
