Market use of NdFeB strong magnets

As the third-generation rare earth permanent magnet material, NdFeB strong magnets have high performance and are widely used in energy, transportation, machinery, medical, IT, microwave, home appliances, aerospace technology and other industries, especially with the development of information technology. Representing the development of knowledge economy, magnet manufacturers continue to bring new uses to functional materials such as rare earth permanent magnet NdFeB industry, which brings broader market prospects to NdFeB industry.

NdFeB strong magnets have been widely used in various fields, especially in modern high-tech fields. Its application can be divided into the following types from the physical principle:

1. Electric energy-mechanical energy conversion, such as: motors, speakers, VCM voice coil motors, etc.;
2. Mechanical energy-electric energy conversion, such as: generators, receivers, measuring instruments, etc.;
3. Mechanical energy–mechanical energy, such as: magnetic separation, magnetic suspension, magnetic transmission, magnetic suspension, magnetic chuck, etc.;
4. Use the physical effects of magnetic fields, such as: magnetic resonance, magnetization to remove wax, magnetization to save fuel, etc.

Electromechanical use of NdFeB market
The emergence of rare earth permanent magnets means that the field of motors will cause revolutionary changes. This is because rare earth permanent magnets have no excitation loss and do not generate heat, and the motors made with them have many advantages. Because the rare earth permanent magnet motor has no excitation coil and iron core, the magnet volume of the magnet manufacturer is smaller than that of the original magnetic field pole, and there is no loss and no heat. Therefore, in order to obtain the same output power, the weight of the whole machine can be reduced by more than 30%, or The same volume and weight, the output power is more than 50% larger.

Speakers and Headphones for NdFeB Market Applications
Speakers and headphones are the traditional application areas of permanent magnets. Today, some high-end speakers use NdFeB.

Microwave devices for NdFeB market applications
In the microwave field, microwave tubes, milliwave tube generators or amplifiers need a stable magnetic field, and rare earth permanent magnets mainly play the role of gathering electron motion in this field.

Magnetic separator for NdFeB market application
There are two types of general magnetic separators: permanent magnet type and electromagnetic type. In the past, the magnets of permanent magnet magnetic separators were mostly ferrite. After the emergence of rare earth permanent magnets, various models and types of permanent magnet magnetic separators were designed and manufactured. Especially in the medium and high magnetic field magnetic separator, rare earth permanent magnets must be used.
