bulk neodymium magnets

Neodymium magnets (also known as "NdFeB", "Neo" or "NIB" magnets) are powerful permanent magnets made from an alloy of neodymium, iron and boron. As part of the rare earth magnet family, they have the highest magnetic properties of all permanent magnets. Due to their high magnetic strength and relatively low cost, they are the preferred choice for many consumer, commercial, industrial and technical applications.

Neodymium magnet shapes


Discs have a larger diameter than thickness.


Rods have a length equal to or larger than the diameter.


Plates include rectangles and thin square magnets.


Cubes have equal length, width, and thickness.


Rings and tubes have straight walls through holes

AH has a large stock of approved neodymium rare earth magnets available for immediate purchase online at bulk discount prices. We offer neodymium discs, rectangular or square neodymium blocks, bars, rings and rods in a variety of sizes, premium grades and finishes.

Neodymium Magnets Applications

Neodymium magnets are used in a variety of applications and are perfect for small parts and assemblies. Common applications range from craft and model-making projects to high-performance motors, medical instruments, audio components, POP displays, science projects, home improvement projects, hanging artwork and more. The following are some of the commonly used industries

Automotive industry

Automotive motors, power steering systems, micro motors and electronic systems all use neodymium to work properly. Large neodymium magnets are a staple in the automotive industry because the material has such a high lift. 

Computer industry

Neodymium is used in many hard disk drives and most models contain several rare earth magnets. Magnetism is the mechanism used to store information on disk drives, with billions to trillions of tiny magnets that hold data coated on the surface of each disk. Hard disk drives read and store information on reliable magnetic systems, which is why exposure to unexpected magnetic fields can interrupt and impair electronic performance. 

In addition to hard disk drives, neodymium is also found in computer speakers, monitors and cooling fans. Without neodymium, there would be no computer industry.

Medical industry

Magnetic resonance imaging (MRI) uses neodymium magnets to identify and diagnose conditions such as migraines, arthritis, cancer, insomnia and chronic pain. In addition to its use in imaging technology, neodymium is used to improve muscle tone and is used by NASA in space flight. Neodymium is also used in orthodontic treatment for orthodontics and palatal expansion. 

Point-of-sale marketing

Magnetic advertising is a cost-effective way of replacing advertisements on a regular basis without damaging the surface. Neodymium magnets are used to hang advertisements in shops and to facilitate price changes. With magnetic advertising, companies can reduce costs by creating interchangeable advertisements and pricing signs.

Introduction and characteristics of neodymium magnets

What are neodymium magnets? 

Neodymium magnets are strong permanent magnets and are part of the rare earth magnet family. They are also known as "NdFeB", "Neo" or "NIB" magnets because they are mainly composed of neodymium (Nd), iron (Fe) and boron (B).

Why are neodymium magnets so strong?

 Neodymium magnets are considered strong because they have a high saturation magnetisation strength and resist demagnetisation. Although they are more expensive than ceramic magnets, strong neodymium magnets pack a powerful punch! A major benefit is that you can use smaller-sized NdFeB magnets to achieve the same goals as larger, cheaper magnets. This may reduce the overall cost, as the overall device size can be reduced

How long do neodymium magnets last? 

If the physical properties of the neodymium magnet remain intact and are not affected by demagnetization (e.g. high temperatures, reverse magnetic fields, radiation, etc.)

What are the main characteristics of neodymium magnets?

 Compared to other rare-earth magnetic materials (e.g. samarium cobalt), neodymium magnets come in a variety of shapes, sizes and grades, are less prone to cracking and breaking and cost less

What are rare earth magnets? 

Rare earth magnets are the strongest type of permanent magnet available today and produce significantly stronger magnetic fields

How are magnets rated? 

Magnets are usually rated according to their residual induction, coercivity and maximum energy product. This is the maximum strength to which the magnetic material can be magnetised

What safety precautions should I consider when using neodymium magnets?

 Neodymium magnets are hard, quite brittle and have a high magnetic strength. They can snap together with great force, so make sure that anyone handling these magnets knows to handle them carefully to avoid injury. They can also break or fracture if dropped or stuck together, so please take extra care when handling these powerful magnets!
