Neodymium (Rare-Earth) Magnets

Neodymium (Rare-Earth) Magnets

Neodymium (NdFeB) Magnets are known as extra strong magnets with high magnetic performance

Neodymium iron boron, also known as NdFeB magnet, is a tetragonal crystal formed by neodymium, iron and boron (Nd2Fe14B). The magnetic energy product (BHmax) of this magnet is greater than that of the samarium cobalt magnet, which was the largest magnet in the world at that time. Neodymium magnet is the most powerful permanent magnet and the most commonly used rare earth magnet. As a part of the rare earth magnet family, neodymium magnets have good magnetic performance, which makes them be they the first choice for many consumer, commercial, industrial and technological applications.

Questions and Answers About Neodymium Magnets

Why are neodymium magnets so strong?

Neodymium rare earth magnets are considered the strongest magnets because they have high saturation magnetization and the highest magnetic energy product. One of the main benefits of using neodymium magnets is that the size of the whole equipment can be minimized.

How long can neodymium magnets keep the magnetism?

As long as the physical characteristics of neodymium magnets remain unchanged and are not affected by demagnetization (such as high temperature, reverse magnetic field, radiation, etc.), the loss of magnetic flux density of neodymium magnet may be less than 1% within 10 years.

What are the main characteristics of neodymium magnets over samarium cobalt magnets?

Compared with other rare earth magnetic materials such as samarium cobalt magnets, neodymium magnets are not easy to crack and break, and the cost is low. However, they are more sensitive to temperature. For this critical application, samarium cobalt may be a better choice because its magnetism is very stable at high temperature.

What shapes are available for neodymium magnets?

Neodymium magnetic material can be made into many shapes,normally include disc magnets,ring&tube magnets,cylinder magnets,cone magnets,countersunk magnets,cube magnet,sphere magnets,rectangular&square magnet blocks.For special shapes that not shown on the website,please contact us for customizing.

Do neodymium magnets need surface coating?

Yes,neodymium magnets must be done with surface coating,any neodymium magnets without surface coating may rust in humid conditions. 

What are permanent magnets?

The magnets which have magnetic fields that do not turn on and off like electromagnets are known as permanent magnets. We supply all kinds of permanent magnets, such as neodymium magnets, AlNiCo magnets, SmCo magnets, ferrite magnets and rubber magnets. Permanent magnets represent the majority of magnetic materials available today.

How are permanent magnets rated?

Permanent magnets are rated by their residual induction, coercive force & maximum energy product. This refers to the maximum strength that the magnetic material can be magnetized.

Do we need safety precautions when using neodymium magnets?

Neodymium magnets are hard, quite fragile and have high magnetic strength. They can bite together strongly, so please make sure that all personnel operating these magnets know to operate with care to avoid injury. If they fall or get stuck together, they can also break or break, so please be very careful when handling these powerful magnets!
