NdFeB Permanent Magnet production process:
Neodymium magnets are actually composed of neodymium, iron and boron (they are also referred to as NIB or NdFeB magnets). The powdered mixture is pressed under great pressure into molds. The material is then sintered (heated under a vacuum), cooled, and then ground or sliced into the desired shape. Coatings are then applied if required. Finally, the blank magnets are magnetized by exposing them to a very powerful magnetic field in excess of 30 KOe.
NdFeB application range:
Electroacoustic field: speakers, receivers, microphones, alarms, stage sounds, car audio, etc.
Electronic appliances: permanent magnet mechanism vacuum circuit breaker, magnetic holding relay, electric meter, water meter, sound meter, reed switch, sensor, etc.
Motor field: VCM, CD/DVD-ROM, generator, motor, servo motor, micro motor, motor, vibration motor, etc.
Mechanical equipment: magnetic separation, magnetic separator, magnetic crane, magnetic machinery, etc.
Healthcare: Nuclear magnetic resonance instruments, medical devices, magnetic health products, etc.
Other industries: magnetized wax protectors, pipe cleaners, magnetic fixtures, automatic mahjong machines, magnetic locks, door and window magnets, luggage magnets, leather bags, magnetized fuel savers. Magnetic toys, magnetic tools, magnetic craft gift packaging, etc.
As For The Prefect Size and Magnetic, JACK CHLOE Mini Magnets Can be Easily attached to Most of Stainless Steel refrigerator, Washing machine, office board, School Lockers Etc.
Prefect For Office, Craft, Science Project,School Supplies, Hobby, Even Creat DIY Project.
Designed to hold even more than traditional Magnets, these Magnets are able to support up to 15 Pcs of paper!!!
ATTENTION: Please keep in mind that magnets do not stick to non-metal materials such as wood, glass, plastic, textile, concrete, etc. However, many non-metal surfaces may have metallic properties, so these magnets will stick on them.
