Neodymium magnet, also called NdFeB magnet, has the characteristics of small size, lightweight, and strong magnetism. It is the magnet with the best performance-to-price ratio so far. These advantages make the application of the NdFeB magnet very wide. So what are neodymium magnets used for? In this article, we will try to answer this question.
Top 8 Uses of Neodymium Magnets
This technology uses a magnetic field to magnetize an object, which can change the nature and bonding state of the object, change the state of atoms and electrons, and catalyze chemical reactions.
2. Magnetic Separation
This technology can extract magnetic materials from non-magnetic materials, and it is commonly used in coal processing, medicine and chemical industries, and water treatment.
3. Lifting Load
For example, some cranes use magnetic force to attract objects, which has the advantages of small size and high force. Magnetic cranes are very suitable for attracting iron blocks, steel, mechanical parts, and other objects.
4. Audio Equipment
In fact, there are neodymium magnets in the audio equipment in our homes, and they play a great role in it. For example, the speaker is a device that converts electrical signals to sound signals, and an important part of it is the neodymium magnet.
5. Microwave Communication
Neodymium magnets are also very useful in communications. For example, magnetrons, satellite communications, radar detection, and electronic tracking all require neodymium magnets.
There are many motors in cars commonly used in our daily lives. Neodymium magnets are an important part of the motors. Its appearance allows the motors to achieve a technological leap in energy saving, smaller size, and higher specific power.
7. Magnetic Therapy
In medicine, neodymium magnets are used to develop magnetic therapy equipment for people to treat joint inflammation, hypertension, coronary heart disease, and other diseases. The principle is to use artificial magnetic fields to treat the lesions of the human body’s acupoints.
8. Magnetic Resonance Imaging
In the cancer oncology department, cardio-cerebrovascular department, and neurological department in the hospital, there is often a test that must be done, that is, magnetic resonance imaging, which can find the lesions of human soft tissues and help doctors make more accurate judgments.
