8 uses of neodymium magnets

Neodymium magnets, also known as NdFeB magnets, are the most powerful magnets on the market at present. Its (BH)max is much larger than that of SmCo magnets. Due to its excellent performance, this magnet is used in all aspects of our life and is the most commonly used. Rare earth magnets, in this article, we will introduce 8 major uses of neodymium magnets.

1. Magnetic Resonance Imaging System: Magnetic Resonance Imaging System (MRI) is an advanced medical imaging diagnostic equipment, which can be used to obtain images of any part of the human body. It is extremely sensitive to soft tissue lesions and is very effective in the diagnosis of cancer, tumor, cerebrovascular and nervous system diseases.

2. Magnetic therapy; Magnetic therapy is a method of using artificial magnetic fields to treat human meridians, acupoints and lesions. Muscle spasm, sprain, cervical spondylosis, etc. have curative effect.

3. Audio equipment: As one of the most important components of audio equipment, speaker is a conversion device that converts electrical signals into sound signals. It consists of many small parts, and neodymium magnets are one of the important parts.

4. Lifting large loads; a magnetic crane is a lifting device that uses magnetic force to lift objects. 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 cylinders. Shaped steel, such as mechanical parts, dies, various steels, etc.

5. Permanent magnet motor; the advantages of permanent magnet motor are copper saving, power saving, light weight, small size and high specific power. Permanent magnet motors are widely used in electric bicycle motors, computer drive motors, elevator traction motor motors, refrigerators, air conditioner motors, wind drive motors, automobile drive motors and other fields.

6. Magnetic separation technology: The technology of separating ferromagnetic substances from non-ferromagnetic substances by magnetism is called magnetic separation technology. Magnetic separation technology has been widely used in beneficiation, coal preparation, raw material treatment, water treatment, garbage treatment and pharmaceutical, chemical, food and other industries.

Seven, microwave communication technology; NdFeB magnets are widely used in radar technology, satellite communications, telemetry, electronic tracking, electronic countermeasures and other fields. In addition, NdFeB magnets are also used in magnetrons, magnetron traveling wave tubes and cathode ray tubes. 8. Magnetization technology: Magnetization technology refers to the use of magnetic fields to magnetize substances, changing the bonding state and properties of the magnetized substances, or changing the states of atoms and electrons, promoting chemical reactions of substances and burning of fuels, or changing the crystal form of substances or freezing point.
