NdFeB magnets are a type of rare-earth magnet made from an alloy of neodymium, iron, and boron, 

which produces a strong and powerful magnetic field. NdFeB magnets have the highest magnetic energy density 

of any commercially available magnet, making them the strongest permanent magnet available today.

These magnets have a high resistance to demagnetization and can maintain their magnetic properties at high 

temperatures, making them suitable for a wide range of applications such as motors, generators, MRI machines, 

headphones, and speakers. NdFeB magnets come in different grades, shapes, and sizes, 

with their strength ranging from N28 to N55, and their maximum operating temperature ranging from 80°C to 230°C.

However, NdFeB magnets also have some drawbacks, such as their susceptibility to corrosion, brittleness, and 

their high cost compared to other types of magnets. Therefore, proper handling, coating, and storage are crucial 

to ensure their long-term performance and durability.

Overall, NdFeB magnets offer an unmatched combination of strength and versatility, making them an indispensable 

component in many high-performance and precision applications.

1. It is called Neodymium Magnet as the name of main material Nd. And there are also Fe, B elements   
    as main material.

2. Material content rate is different as the grade, High grades need heavy rare earth element Td, Dy, Yb.

3. It is the most powerful magnet of permanent magnets.

4. It is widely used because It can maintain magnetic force from external magnetic field.

5. Usage for Motor, Sensor, Speaker, Stationery, Metal selector,  attachment/fixing parts  or packing   

    material  etc.

6. One of popularized magnet  with sintered Ferrite magnet.

7. Precision  of magnetic force could be managed as grade and method of manufacturing.
