Neodymium iron boron magnet is a kind of permanent magnet, which is used in all aspects of our lives. It is a tetragonal crystal formed by neodymium, iron and boron (Nd2Fe14B). Neodymium iron boron magnets have achieved market development and wide application due to their excellent performance, abundant raw materials and reasonable prices. It is the strongest permanent magnet today and the most commonly used rare earth magnet. So, what are the uses of neodymium iron boron magnets?
Neodymium iron boron magnet
This technology uses a magnetic field to magnetize an object, which can change the nature of the object, the bonding state, the state of atoms and electrons, and catalyze chemical reactions.
2. Magnetic separation
This technology is also called magnetic separation technology, which can extract magnetic materials from non-magnetic materials. It is commonly used in coal processing, medicine and chemical industries, and water treatment.
3. Lift the load
For example, there is a kind of crane that uses magnetic force to suck up objects. It is small in size and large in force. Magnetic cranes are very suitable for adsorbable objects such as iron blocks, steel materials, and mechanical parts.
The influence of our house is actually a neodymium iron boron magnet in it, and it has a great effect in it. The speaker is a device that converts the electrical signal to the sound signal, and the important part of it is the neodymium iron boron magnet.
5. Microwave communication
Neodymium iron boron magnets are also very useful in communication. Magnetrons, satellite communications, radar detection, electronic tracking, etc. all need neodymium iron boron magnets.
6. Permanent magnet motor
There are many motors in the cars we see every day. Neodymium iron boron magnets are an important part of the motors. Its appearance allows the motors to achieve a more energy-saving, smaller volume, and higher specific power technology.
Using neodymium-iron-boron magnets in medicine, it has developed a magnetic therapy device specifically 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.
