Permanent magnets are widely used in many areas such as wind energy,automobile industry, aerospace, audio-visual equipment, medical equipment,mining equipment and health care, sports equipment, LED lighting, electrical appliances, luggage, hardware and plastics, etc.
For example,magnet plays an important role in the packaging box. It makes the packaging box more high-grade and fashionable. The packaging magnet is installed at the upper and lower parts of the box. When the upper and lower parts cover each other, the magnets attract each other.
The most commonly known of magnet used in the medical field is MRI. Using this nuclear magnetic resonance imaging technology, We can diagnose abnormal human tissues and judge diseases. In addition, the interaction between magnetic field and human meridians can also realize magnetic therapy. At present, products such as magnetic therapy pillow and magnetic therapy belt are also very popular in well-being market.
In the traditional industrial field, magnet in generators are used for power generation, transformers are used for power transmission, loudspeakers are used for TV sets, motors are used for electric machinery etc., and magnetic steel coil structure is used in too many instruments and meters, it can be said that electrification is impossible without magnetic materials.
