EnglishA neodymium magnet is a type of permanent magnet made from an alloy of neodymium, iron, and boron. These magnets are also known as NdFeB magnets, which stands for Neodymium-Iron-Boron. They are the most powerful permanent magnets available, and have a high resistance to demagnetization.
Neodymium magnets are used in a wide range of applications, including in motors, generators, headphones, loudspeakers, magnetic resonance imaging (MRI) machines, and many others. They have a strong magnetic field and can attract or repel other magnets from a distance.
Neodymium magnets come in various shapes and sizes, including discs, cylinders, cubes, and rings. The strength of the magnet depends on its size and shape, as well as the grade of the alloy used to make it.
One of the key advantages of neodymium magnets is their high strength-to-weight ratio, which makes them ideal for applications where weight is a concern. They are also relatively affordable compared to other types of high-performance magnets.
However, neodymium magnets also have some limitations. They are brittle and can break or chip easily, so they need to be handled with care. They are also vulnerable to corrosion, so they need to be coated or plated to protect them from moisture and other environmental factors.
In summary, neodymium magnets are a type of powerful permanent magnet made from an alloy of neodymium, iron, and boron. They are used in a wide range of applications and come in various shapes and sizes. They have a high strength-to-weight ratio, but are brittle and vulnerable to corrosion.

It is sintered neodymium magnet, it is a powder metallurgy technique.The smelted alloy is made into powder and pressed into a compact in a magnetic field. The compact is sintered in an inert gas or vacuum to achieve densification. In order to improve the coercivity of the magnet, an aging heat treatment is usually required.
