How strong are super magnets / neodymium magnets

Super magnets are fascinating and extremely powerful magnets that play an important role in a wide variety of applications.
It is a synonym for neodymium magnets Neodymium (more precisely neodymium-iron-boron, or NdFeB) magnets have become commonplace. NdFeB) magnets and is due to the extreme holding force / adhesive force of neodymium magnets:

Here you can find our strong super magnets:

For a long time, ferrite magnets were the measure of all things and therefore the strongest permanent magnets available.

It was only with the development of rare earth magnets by General Motors and Sumitomo in 1982 that a new era for magnets was ushered in.

So-called neodymium magnets made of neodymium, iron and boron (Nd₂Fe₁₄B) have a crystal structure with high anisotropy and extremely high coercive field strengths. With a maximum magnetic energy density of approx. 500 kJ/m³, they put ferrite magnets (typically around 30 kJ/m³) in the shade. The adhesive force of a neodymium magnet is approx. 10 times greater than that of a ferrite magnet of the same volume. In other words, you need a much larger ferrite magnet to generate the same adhesive force as a neodymium magnet (super magnet).
Neodymium magnets, also known as super magnets, are therefore the strongest magnets available in the world today.
A neodymium magnet (super magnet) with an edge length of a few centimetres can achieve an adhesive force of several 100 kg.

Since super magnets are the most popular of all magnets, we have also decided to use them for most of our office magnets and pinboard magnets. This way, even small cone-shaped office magnets can generate enough force to attach many notes or small notebooks to the pinboard. You can buy all of these magnets in our magnet shop.

Tips for handling super magnets

Caution is advised when handling super magnets, as they have such a strong attraction that they can easily shatter or attract metal objects. Gloves and safety goggles should therefore be worn when handling large and powerful magnets, some of which have a holding force of several hundred to thousand kg, to avoid injury. It is also advisable to keep super magnets away from some electronic devices, credit cards and other sensitive objects, as they can affect them.

So when it comes to maximising the strength of magnets while keeping them as small as possible, super magnets - neodymium magnets are the first choice.
