What Are Strong Magnets & What Are their Applications?
What Are Strong Magnets?
Many people who are searching for specific magnet types may come across the term “strong magnet” in their search. So what are strong magnets? Usually, strong magnets refer to neodymium magnets or NdFeB magnets. The magnetic properties of NdFeB magnets greatly exceed that of the ferrite magnets, Alnico magnets, and SmCo magnets. For example, the weight of the object that the NdFeB magnet can suck is 640 times its own weight. That’s the reason why they are often referred to as strong magnets.
NdFeB magnets have the characteristics of small size, lightweight, and strong magnetism and are the most cost-effective magnet by far. It is expected that in the next 20-30 years, there will be no replacement for NdFeB magnetic materials.
The main raw materials for producing NdFeB magnets are rare earth metal neodymium, praseodymium metal, pure iron, aluminum, ferroboron alloy, and other rare earth raw materials.
The core technology of the NdFeB industry is mainly reflected in the manufacturing process, specifically in the aspects of the uniformity, consistency, processing quality, and coating quality of the products.
What are the applications of strong magnets?
NdFeB magnets, as the third generation rare earth permanent magnet material, have a very high cost-performance and are widely used in the field of electroacoustics, electronic appliances, motors, mechanical equipment, medical care, and so on.
1. Electroacoustics
In the field of electroacoustics, strong magnets are widely used in speakers, receivers, microphones, alarms, stage audio, car audio, etc.
2. Electronic Appliances
In the field of electronic appliances, strong magnets also have a broad application in the permanent magnet mechanism vacuum circuit breaker, magnetic holding relay, watt-hour meter, water meter, sound meter, reed switch, sensor, etc.
3. Motors
You can also find strong magnets in various motors, such as VCM (Voice Coil Motor), CDDVD-ROM, generator, servo motor, micro motor, vibration motor, etc.
4. Mechanical Equipment
Some mechanical equipment, such as magnetic separator, magnetic crane, magnetic machinery, etc., are also inseparable from strong magnets.
5. Medical Care
In the field of healthcare, strong magnets have also been widely used. For example, MRI instruments, medical equipment, magnetic therapy health products, and magnetized fuel economizers all require strong magnets.
6. Other Fields
At the same time, strong magnets are also broadly employed in magnetized wax guards, pipeline descalers, magnetic fixtures, automatic mahjong machines, magnetic locks, door and window magnets, luggage magnets, leather magnets, toy magnets, tool magnets, craft gift packaging, etc.
