Neodymium Permanent Magnet with micro size use for phone speaker

There are eight uses for Neodymium Magnet, each of which plays an important role in life.

1. Magnetization

The technology is to use magnetic field to magnetize the object, which can change the properties and bonding states of the object, change the state of atoms and electrons, and catalyze the chemical reaction.

2. Magnetic separation

This technology, also known as magnetic separation technology, can extract magnetic materials from non-magnetic materials, which is widely used in coal processing, pharmaceutical, chemical industry and water treatment.

3. Lift the load

For example, there is a kind of crane that uses magnetic force to suck up objects. It has small volume and large force, such as iron, steel, mechanical parts and other adsorbable objects. Magnetic crane is very suitable.

4. Sound

In fact, there are NdFeB magnets in our family, and they play an important role in it.

The loudspeaker is a device for converting the sound signal of telecommunication signals, and the important part of it is neodymium magnets.

5. Microwave communication

NdFeB magnets are also very useful in communication, such as magnetron, satellite

communication, radar detection and electronic tracking.

6. Permanent magnet motor

In the cars, there are many motors. Neodymium iron boron magnet is an important

part of the motor. Its appearance makes the motor realize the technological leap of more energy saving, smaller volume and higher specific power.

7. Magnetic therapy

In medicine, we use neodymium magnet to develop a magnetic therapy equipment

for the treatment of arthritis, hypertension, coronary heart disease and other diseases. The principle is to use artificial magnetic field to treat the location of acupoint and vein lesions.

8. Magnetic resonance imaging

In the cancer and oncology department, cardio cerebrovascular department and

nervous system Department of the hospital, there is often a test that must be done, that is magnetic resonance imaging, which can find the lesions of human soft tissue and help doctors make more accurate judgments

This Magnet is used for the micro motor used in phone.
