Ndfeb magnets are widely used and have their unique advantages in many aspects.
Here is a brief introduction to the uses of Ndfeb magnets.
First, used in electronic computers and communication equipment: as a heat dissipation material for cpu, it can greatly reduce the working temperature and extend the service life.
Applications used as permanent magnets are: 1, manufacturing magnetic resonance coils (or disks), such as disk drives; 2. Make various tape recorders; 3. Ring polaron for manufacturing optical fiber; 4, for ultra-small loudspeaker tweeter; 5, the production of magnetic drum pieces in the tape recorder;
Third, the applications used as electroacoustic transducers are: 1, the receiver of the machine with soft magnetic core instead of steel reed to reduce the volume and weight; 2. The muffler in the TV uses a soft magnetic core instead of a paper basin to reduce noise; 3, audio equipment with soft electromagnetic instead of the traditional cylindrical speaker to increase the effective volume; 4 On the computer monitor, soft magnetic thin film transistor (tft) is used to make a large screen color display board; 5. Astern radar device on the car; 6 Gyroscope systems on aircraft; 7 The switch used to control the number of motor revolutions on the electric shaver.
Fourth What are the precautions for storage and transportation of neodymium iron boron magnetsFourt
(1) Pay attention to the indoor humidity, must be maintained at a dry level, the temperature does not exceed room temperature;
② Products in black block or blank state can be properly oiled when stored (general oil can be used);
(3) Electroplating products should be vacuum sealed or stored in isolated air to ensure the corrosion resistance of the coating;
(4) Magnetized products should be sucked together and stored in boxes to avoid sucking up other metal bodies;
⑤ Magnetized products should be stored away from disks, magnetic cards, tapes, computer monitors, watches and other objects sensitive to magnetic fields.
Magnetized transport should be shielded, especially air transport must be thoroughly shielded.
