Neodymium magnets are a type of rare earth magnet. Currently known, Neodymium Magnets are the strongest permanent rare earth magnet in existence.
The Neodymium Magnets which are made from rare-earth metals are much more powerful and are called ‘Super Magnets’.
They are used mostly in industry, e.g., in computer hard drives, speakers, electric motors, household items and toys. Neodymium Magnets are popular and are also used for a variety of purposes including medical magnetic therapy.
Neodymium Magnets activate powerful magnetic fields that might interrupt the activity of electronic equipment, including medical devices – for example, pacemakers. They can also attract metal objects from a few inches away which might trap the handlers’ hand between the magnet and the metallic object.
Neodymium Magnets can also produce toxic fumes if burned. Therefore, they have to be handled with care. Additionally, Neodymium Magnets are so breakable that they have to always be at least 12 inches away from nearby super magnets.
What are Neodymium rare earth Magnets and how are they manufactured?
Neodymium rare earth Magnets are among the most powerful magnets available relative to their size – Small is Big! They contain a lot of energy, are relatively cheap and are usually available to customers through a third party vendor.
Neodymium Magnets are composed of an alloy of neodymium, boron and iron. However, before manufacturing the magnets, the alloy is grinded into powder form.
A powdered metallurgy method which is known as sintering is used to produce the Neodymium Magnets. The metal particles are pressed into a shape, leveled and heated until the particles adhere but do not melt – this technique is used to produce the base material for these Magnets. After sintering, the material is cut into the desired size and magnetized.
Features of Neodymium Magnets
Magnet strength is measured in units of gauss and the Neodymium Magnets are generally very powerful. Thus, Neodymium Magnets have a strong holding strength on metal platforms and can be used as components for holding, separating etc. This sort of super magnet can exist in temperatures up to 80 degrees Celsius before losing magnetization.
