Common Applications of Neodymium Magnets

Neodymium magnet, also known as NdFeB magnet, is a tetragonal crystal formed by neodymium, iron, and boron. The NdFeB magnet is a kind of permanent magnet and is also the most commonly used rare earth magnet. Its magnetism is second only to the absolute zero-degree holmium magnet. In this article, let's take a look at the common applications of neodymium magnets.

Common Applications of Neodymium Magnets Common Applications of Neodymium Magnets

1. Applications of Neodymium Magnets in the Field of Microwave Communication Technology

NdFeB magnets are widely used in radar technology, satellite communications, remote control telemetry, electronic tracking, and electronic countermeasures. In addition, magnets are also used in magnetron tubes, magnetron traveling wave tubes, cathode ray tubes, and circulators.

2. Applications of Neodymium Magnets in the Field of Electrical Engineering

More than one-third of the output of the neodymium magnets is used to manufacture various permanent magnet motors. The advantages of permanent magnet motors are copper saving, power saving, lightweight, small in size, and high specific power. For example, neodymium magnets are widely used in electric bicycle motors, elevator traction machine motors, refrigerator air conditioner motors, wind-driven motors, etc.

3. Applications 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 receivers, electro-acoustic sensors, etc.

4. Applications of Neodymium Magnets in the Field of Magnetic Mechanical Engineering

This kind of magnet is used to produce various pieces of magnetic machineries, such as magnetic gears, magnetic brakes, magnetic fixtures, magnetic salvage devices, magnetic bearings, magnetic pumps, magnetic valves, magnetic seal doors, magnetic locks, and permanent magnet jack, permanent magnet conveyor, etc.

5. Applications of Neodymium Magnets in the Field of Transportation

Neodymium magnets have also been widely used in transportation, such as magnetic suspension trains, and permanent magnet devices for luxury cars, like windshield wiper motors, oil pump motors, window opening motors, door lock motors, starter motor, etc.

6. Applications of Neodymium Magnets in the Field of Magnetic Separation Technology

The technique of using magnetic methods to separate ferromagnetic substances from non-ferromagnetic substances is called magnetic separation technology. Magnetic separation technology has been widely used in beneficiation, coal preparation, raw material treatment, water treatment, and garbage treatment, as well as in medical treatment, the chemical industry, and the food industry.

7. Applications of Neodymium Magnets in the Field of Magnetization Technology

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

8. Applications 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. Besides, neodymium magnets are also used in MRI, a medical device that has developed rapidly in recent years. In short, since the invention of this magnet, new fields of application have appeared every year, and the annual growth rate is more than 30%. Therefore, the application prospect of neodymium magnets is very broad.
