Neodymium magnets

The Neodymium magnet (Nd-Fe-B, which is an alloy of neodymium, iron and boron) also called permanent magnet, super magnet or rare earth magnet is the most powerful magnet in the world. Neodymium magnets are widely used for numerous purposes that require an extremely strong and permanent magnetic field, including: building wind generators and turbines, various technological experiments, designing all kinds of devices and mechanisms, attaching metal objects, tying together iron parts, underwater soil research, model building, metal detector building, water pipe decalcification, tricks and magic,etc,etc...

What is N - value ?

The N grade or N value of the magnet refers to the Maximum Energy Product of the material from which the magnet is made. The N-Grade indicates the maximum force to which a certain magnet can be magnetised. The lowest possible N-degree for neodymium magnets is N35, the highest is N52.

Why do we sell neodymium magnets N38?

Neodymium magnets N38 offer an excellent quality without becoming very expensive. Previously, we sold the N52 magnets in addition to our N38 magnets. However, after our own long research and careful consultation with our manufacturer, we stopped doing this because the production of N52 magnets is much more expensive due to large quantities of rejected specimens. Our N38 magnets are considerably less brittle, which facilitates the production and in practice guarantees the durability of the magnet. At the same time, the difference in strength between an N38, an N45 and an N52 magnet of the same size is absolutely negligible, it only amounts to a few percent.


Neodymium magnets may interfere with the operation of some devices and should be kept away from them. This includes measuring devices such as watches, scales, gas and electricity meters, mobile phones, credit and debit cards, computers and TV sets etc. ....

Read the Safety Instructions before working with the magnets:
  • The neodymium magnets can be potentially dangerous due to their extreme strength.

  • Extreme care must be taken when working with the magnets.

  • Loose magnets can jump towards each other unexpectedly, for example, even over a distance of 1 metre.

  • When the magnets collide, they can break to pieces, and flying splinters can cause injuries.

  • Moreover, skin can be pinched between two magnets: therefore always wear suitable face and hand protection.

  • Pacemaker wearers should not handle magnets.

  • Neodymium magnets are NOT TOYS and are absolutely not suitable for children. Keep your magnets out of sight and out of reach of children.

  • Max working temperature of the magnets is 80 degrees Celsius. Magnets cannot be drilled or dragged. If you do, your magnet may lose some or all of its power.
