10~5000PCS 3×3 mm Search Minor Disc Magnet 3mmX3mm Bulk Small Round Magnets 3x3mm Neodymium Round N42 Strong Magnets 3*3 mm 3mm

Neodymium (chemical symbol Nd) is the 60th element in the periodic table. It is a rare earth metal that belongs to the lanthanide series. When added to iron (Fe) and boron (B) (chemical formula Nd14Fe21B), the resulting magnet is the strongest currently available. Neodymium magnets are sometimes called Neo, Neod or NIB magnets. Neodymium magnets are usually coated with a nickel-copper-nickel plating to prevent the iron from rusting. NdFeB block magnet, strong magnetism, no rust appearance, placed at room temperature, maximum working temperature 80 ℃, never demagnetization. Applied acoustics fields: speakers, receivers, microphones, alarms, stage audio, car audio, etc. Electronic products: permanent magnet actuator vacuum circuit breaker, magnetic relay, electric meter, sound meter, reed switch, sensor. Electrical field: VCM, CD/DVD-ROM, generator, motor, servo motor, micro motor, vibration motor. Mechanical equipment: magnetic separator, magnetic crane, magnetic machinery. Healthcare: MRI scanners, medical equipment, magnetic healthcare products, etc. Other industries: magnetized wax, pipe descaling, magnetic fixtures, automatic mahjong machines, magnetic locks, door magnets, magnetic luggage, leather magnetic toys, magnetic tools, gift packaging. Tips 1. Strong magnets should be kept away from hardware appliances and iron products that are easily magnetized, such as monitors, bank cards, computers, TVs, mobile phones, etc. 2. Powerful magnets should be stored in a dry and heated environment, and need to be separated and wrapped with plastic, wood, cardboard, and foam. 3. Magnets may have some inaccurate effects on water meters, electric meters, gas meters and some metering equipment (for example: if the magnet is placed near the meter, the meter will slow down) Please note that when connecting two magnetic buttons, please pull them Open slowly and gently approach each other. Hard crushing can cause damage and cracks to the magnetic material. Magnets are made of Neo Neodymium magnet material for incredible magnetic properties.
