Neodymium super magnets
Super magnets are magnets that are made from the raw material neodymium-iron-boron, or NdFeB for short. Compared to conventional magnets, super magnets made of neodymium have a significantly higher adhesive force, meaning they can hold a much greater weight.
Super magnets are needed in many areas of industry. They are used in the construction of electric motors or as block magnets in model making. Flat grippers are also often fitted with neodymium magnets to make them stronger. A super magnet is a permanent magnet, which means that the magnetic effect is permanent and cannot be switched off as with an electromagnet, for example
However, caution is advised when handling super magnets! Due to the strong attractive forces, fingers can quickly be injured even with smaller magnets. As the material is very brittle, the magnets can easily splinter, especially if they collide in an uncontrolled manner. Caution is also advised with pacemakers and other medical devices. The strong magnetic fields impair the functionality of electrical devices.
Classification of super magnets into quality classes
Super magnets are available in different grades, which are characterised by designations such as N30 or N42. The higher the magnetisation grade, the higher the energy product - and therefore also the adhesive force - of the magnet and the more the magnet holds. You can find an overview of the various magnetic properties here.
One of the magnetic properties of super magnets, however, is that they usually have a lower operating temperature and are more expensive than conventional ferrite magnets.
Super magnet moulds
Super magnets are manufactured in various shapes. Depending on the application, ring magnets, rod magnets or other shapes are used. For example, flat grippers in which neodymium super magnets have been installed are suitable for attaching awnings to a steel structure.
Possible applications for super magnets
The possible applications for block magnets, ring magnets or rod magnets made of neodymium are extremely diverse. They can be used wherever strong magnetic fields are required. A super magnet can show its strengths when used in a power generator, for example. Due to their efficiency and performance, NdFeB alloy magnets are also able to increase the performance of power generators in wind turbines many times over. The permanent magnets with their strong adhesive force are also regularly used in medicine. Super magnets can even be used in everyday life on pinboards or as fridge magnets. These are just a few of the many possible applications. You can find more inspiration in the magnet applications of our customers on our blog.
