The Wide Use of Neodymium Hook Magnets in Different Fields

1. What neodymium hook magnets are?

Neodymium hook magnets are also called NdFeB magnets. They are permanent magnets with a Nd2Fe14B tetragonal texture, and they are made of an alloy of neodymium, iron, and boron. Their main ingredients are the rare earth element neodymium (Nd), iron (Fe), and boron (B).

Neodymium, known as rare earth, is part of this material. Its rarity is due not only to its natural abundance but also to the difficulty of separating them from other chemically bonded materials.

As a result, neodymium hook magnets are not the cheapest, but they are the most powerful, and this relatively great power can exist in a few centimeters of the magnet.

With nickel, zinc, or copper coatings, neodymium hook magnets have excellent atmospheric resistance. Neodymium hook magnets are the strongest magnets on the market, so they are known as the king of magnets. They are highly magnetic, and they have a maximum energy volume (BH) max greater than 10 times that of ferrite magnets.

NdFeB have excellent machining performance, and it operates at temperatures up to 200°C. In addition, neodymium hook magnets have stable performance and good cost performance, so they are widely used in various industries.

2.  What are the applications of neodymium hook magnets?

In modern products that require strong permanent magnets, neodymium hook magnets have replaced other types of magnets. The applications of NdFeB magnets are as follows:

A. Electronic acoustic field: loudspeaker, receiver, microphones, alarms, stage audio, car audio, and so on;

B. Electronics: permanent magnet mechanism vacuum circuit breaker, magnetic hold relay, electricity meter, water meter, sound level meter, reed switch, sensor, and so on;

C. Electrical field: VCM, CDDVD-ROM, generators, motors, servo motors, micromotors, vibration motor, and so on;

D. Mechanical equipment: magnetic separator, magnetic separator, magnetic crane, magnetic machinery, and so on;

E. Medical care: MRI machines, medical equipment, magnetic health care products, magnetic economizer, and so on;

F. Other fields: anti-magnetization wax, pipeline scale remover, magnetic fixator, automatic mahjong machine, magnetic lock, door and window magnets, stationery magnets, bag magnets, leather magnets, toy magnets, tools magnets, craft gift wrappers, and so on.
