Neodymium magnet is also called the NdFeB magnet. The neodymium magnet is the strongest magnet available on the market today, with a (BH)max much larger than that of the SmCo magnet. Because of its excellent properties, this magnet is applied to all aspects of our lives and is the most commonly used rare earth magnet. In this article, we will introduce the top 8 uses for neodymium magnets.
1. Magnetic Resonance Imaging System
Magnetic Resonance Imaging System (MRI) is a cutting-edge medical imaging diagnostic equipment. It can be used to obtain images of any section of the human body. It is extremely sensitive to soft tissue lesions and is very effective for the diagnosis of cancer, tumor, cerebrovascular, and nervous system diseases.
Magnetotherapy is a method that uses artificial magnetic fields to apply to human meridians, acupuncture points, and lesions to treat certain diseases. The professional magnetic therapy equipment from the hospital has effects on hypertension, arthritis, headache, insomnia, coronary heart disease, gastroenteritis, facial muscle spasm, sprains, and cervical spondylosis.
3. Audio Equipment
As one of the most important components in the audio equipment, a speaker is a kind of transducing device that converts the electrical signal into the acoustic signal. It is composed of many small parts, and the neodymium magnet is one of the important parts.
4. Lifting Large Loads
Magnetic crane is a lifting device that lifts objects by magnetic force. It has the characteristics of small size, strong lifting capacity, no need for electricity and other energy drives, and high safety. It is suitable for handling steel plates, iron blocks, and cylindrical steel materials, such as mechanical parts, punch molds, and various steel materials.
5. Permanent Magnet Motors
The advantages of permanent magnet motors are copper saving, power saving, lightweight, small size, and high specific power. Permanent magnet motors are widely used in electric bicycle motors, computer-driven motors, elevator traction machine motors, refrigerator, and air-conditioning motors, wind-driven motors, automobile-driven motors, and other fields.
6. Magnetic Separation Technology
The technique of using magnetism 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, garbage treatment, as well as in medical, chemical, and food industries.
7. Microwave Communication Technology
NdFeB magnets are widely used in radar technology, satellite communications, remote telemetry, electronic tracking, and electronic countermeasures. In addition, NdFeB magnets are also used in magnetron tubes, magnetron traveling wave tubes, and cathode-ray tubes.
8. Magnetization Technology
Magnetization technology refers to the use of a magnetic field to magnetize a substance, change the bonding state and nature of the substance being magnetized, or change the state of atoms and electrons, promote the chemical reaction of the substance and the combustion of the fuel, or change the crystal form or freezing point of the substance.
