The Main Function and Application of Neodymium Magnet

Zhaobao Magnet

With the continuous advancement of science and technology, the use of NdFeB magnets is very common, and the use of NdFeB magnets is becoming more and more obvious. 

NdFeB magnets not only have small size, light weight and strong magnetic properties, but the most important raw materials of NdFeB magnets are metal neodymium, pure iron, iron boron alloys and other additives, so NdFeB magnets will have Such good performance. 

Next, this article will introduce to you what are the main functions and applications of neodymium magnets? Please read patiently!


Introduction to Neodymium Magnets

Neodymium magnets (also known as “NdFeB”, “Neo” or “NIB” magnets), are strong permanent magnets made from an alloy of neodymium, iron & boron. Part of the Rare-Earth magnet family, they have the highest magnetic properties of all permanent magnets. Due to their high magnetic strength and relatively low-cost, they are the preferred choice for many consumer, commercial, industrial and technical applications. (Neodymium magnet wikipedia)


What Are the Functions of NdFeB Magnets?

1. Magnetization

Using a magnetic field to magnetize an object can change the properties and bonding state of the object, change the state of atoms and electrons, and catalyze chemical reactions.

2. Magnetic separation

Magnetic separation, also known as magnetic separation technology, can extract magnetic substances from non-magnetic substances, and is commonly used in mineral processing, coal, medicine and chemical industry, and water treatment.

3. Lift the load

Magnetic cranes are very suitable for objects that can be adsorbed such as iron blocks, steel, mechanical parts, etc., such as cranes, which use magnetic force to attract objects.

4. Audio

The neodymium-iron-boron magnets in our daily audio also play a very important role. The speaker is a device that converts electrical signals and sound signals, and an important part of it is the neodymium-iron-boron magnet.

5. Microwave Communication

NdFeB magnets are also of great use in communications. NdFeB magnets are required for magnetrons, satellite communications, radar detection, and electronic tracking.

6. Permanent magnet motor

In the cars we see every day, there are many motors. NdFeB magnets are an important part of the motor. Its appearance allows the motor to achieve a technological leap in more energy-saving, smaller size and higher specific power.

7. Magnetic therapy

In medicine, NdFeB magnets are used to develop magnetic therapy equipment for people to treat joint inflammation, hypertension, coronary heart disease and other diseases.


What Are the Main Applications of NdFeB Magnets?

What are the main application fields of NdFeB? At present, the main applications of neodymium magnets are in the following fields.

1. Electroacoustic field: speakers, receivers, microphones, alarms, stage audio, car audio, etc.

2. Electronic appliances: permanent magnet mechanism vacuum circuit breakers, magnetic latching relays, watt-hour meters, water meters, sound meters, reed switches, sensors, etc.

3. Motor field: VCM, CDDVD-ROM, generators, motors, servo motors, micro motors, motors, vibration motors, etc.

4. Mechanical equipment: magnetic separation, magnetic separator, magnetic crane, magnetic machinery, etc.

5. Healthcare: nuclear magnetic resonance apparatus, medical equipment, magnetic therapy health care products, magnetized fuel saver, etc.

6. Other industries: magnetized wax inhibitor, pipe descaling device, magnetic fixture, automatic mahjong machine, magnetic locks, door and window magnets, stationery magnets, luggage magnets, leather magnets, toys magnets, tool magnets, craft gift packaging, etc.


Where To Buy Neodymium Magnets

Nowadays, it is no exaggeration to say that our lives are supported by NdFeB magnets. From speakers to air conditioners, from refrigerators to electric vehicles, there must be magnets on the motors that convert electric current into power. It can be said that magnets give us modern Comfortable life.
