Application of neodymium iron boron magnets

Neodymium magnet, also known as neodymium iron boron magnet, is a tetragonal crystal composed of neodymium, iron, and boron. Neodymium iron boron magnet is a type of permanent magnet and the most commonly used rare earth magnet. Its magnetism is second only to absolute zero degree holmium magnets. In this article, we will take a look at the common applications of neodymium magnets.

1. The application of neodymium magnets in the field of microwave communication technology

Neodymium iron boron magnets are widely used in radar technology, satellite communication, remote control and telemetry, electronic tracking, and electronic countermeasures. In addition, magnets are also used in magnetrons, magnetron traveling wave tubes, cathode ray tubes, circulators, and so on.

2. The application of neodymium magnets in the field of electrical engineering

More than one-third of the production of neodymium magnets is used to manufacture various permanent magnet motors. The advantages of permanent magnet motors are copper and electricity saving, light weight, small size, and high specific power. For example, neodymium magnets are widely used in electric bicycle motors, elevator traction machine motors, refrigerator air conditioning motors, wind turbines, and so on.

3. The application of neodymium magnets in the field of electroacoustic devices

For example, neodymium magnets are used to manufacture speakers, microphones, hearing aids, stereo headphones (MP3, MP4), telephone earphones, electroacoustic sensors, etc.

4. Application of neodymium magnets in the field of magnetic mechanical engineering

This type of magnet is used to make various magnetic mechanical parts, such as magnetic gears, magnetic brakes, magnetic fixtures, magnetic fishermen, magnetic bearings, magnetic pumps, magnetic valves, magnetic sealing doors, magnetic locks and permanent magnet jacks, permanent magnet conveyors, etc

5. The application of neodymium magnets in the field of transportation

Neodymium magnets have also been widely used in transportation, such as maglev trains and permanent magnet devices in luxury cars, such as wiper motors, oil pump motors, window opening motors, door lock motors, starting motors, etc.

6. Application of neodymium magnets in magnetic separation technology

The technology of using magnetic methods to separate ferromagnetic materials from non-ferromagnetic materials is called magnetic separation technology. Magnetic separation technology has been widely applied in mineral processing, coal preparation, raw material treatment, water treatment, garbage treatment, as well as medical, chemical, food and other industries.

7. The application of neodymium magnets in the field of magnetization technology

Magnetization technology refers to the use of a magnetic field to magnetize a substance, change the bonding state and properties of the magnetized substance, or change the atomic and electronic states, promote chemical reactions of the substance, or change the crystal form or solidification point of the substance.

8. The application of neodymium magnets in the field of magnetic therapy and fitness equipment

Neodymium magnets are used to manufacture magnetic therapy cups, magnetic balls, magnetic therapy machines, magnetic therapy shoes, magnetic therapy caps, magnetic therapy bracelets, necklaces, etc. In addition, neodymium magnets have also been used in magnetic resonance imaging, a rapidly developing medical device, in recent years.

In short, since the invention of this magnet, new application areas have emerged every year, and the annual growth rate has been over 30%. Therefore, the application prospects of neodymium magnets are very broad.
