Standard Configurations
Discs
Discs are round or cylindricalNeos and generally are identified by the diameter first then the height of the disc. So a magnet labeled as 0.500” x 0.125” is a 0.500” diameter by 0.125” tall disc. Unless specified otherwise, these magnets are magnetized through the thickness.
Rings
Rings are round Neos that have a hole in the center. These Neodymium magnets that are available for sale will require three dimensions, an outside diameter, and an inside diameter and thickness. Unless specified otherwise, these magnets are magnetized through the thickness.
Blocks
Neo blocks are rectangular or square with a variety of size options. These will require three measurements: length, width, and thickness. Unless specified otherwise, these magnets are magnetized through the thickness.

NEODYMIUM BENEFITS
Neodymium is a ferromagnetic metal, meaning it is easily magnetized at a cost-effective price point. Out of all permanent magnets, Neodymium is the most powerful, and it has more lift for its size than samarium cobalt and ceramic magnets. Compared to other rare earth magnets such as samarium cobalt, big Neodymium magnets are also more affordable and resilient.
Neodymium has the greatest power-to-weight ratio and a high resistance to demagnetization when used and stored at the correct temperatures.
NEODYMIUM USES AND APPLICATIONS
Neodymium is a popular magnet of choice for products and industries such as:
AUTOMOTIVE INDUSTRY
Automotive motors, power steering systems, micromotors and electronic systems all use Neodymium to function correctly. Large Neodymium magnets are a staple of the automotive industry since this material has such high lift power.
COMPUTER INDUSTRY
Neodymium is used in many hard disc drives, with most models containing several rare earth magnets. Magnetism is the mechanism used to store information on disc drives, and the surface of every disc is coated in billions to trillions of tiny magnets that hold data. Hard drives read and store information on reliable magnetic systems, which is why exposure to unexpected magnetic fields can interrupt and harm electronic performance.
Aside from hard drives, Neodymium is found in computer speakers, monitors and cooling fans. Without Neodymium, there is no computer industry.
MEDICAL INDUSTRY
Magnetic resonance imaging (MRI) uses Neodymium magnets to identify and diagnose illnesses such as migraines, arthritis, cancer, insomnia and chronic pain. In addition to its use in imaging technology, Neodymium can be used to improve muscular toning and is used by NASA during space flights. Neodymium is also used in orthodontic treatment for realignment of the teeth and palatal expansion.
POINT-OF-SALE MARKETING
Magnetic advertising is a cost-effective way to regularly change out advertisements without risking damage to surfaces. Neodymium magnets are used to hang advertisements inside stores and facilitate easy price changing. Through magnetic advertising, companies can reduce costs by creating advertisements and pricing signs that can be swapped out.
In addition to its roles in the automotive, computer, medical and marketing industries, Neodymium is used in the following products:
- Audio equipment
- Cordless power tools
- Door catches
- Electric engines
- Generators
- Home improvement
- Jewelry
- Magnetic separators
Many of us interact with Neodymium products every day and don't even know it. In addition to being used in magnets, Neodymium is frequently employed in glass production. Some of its everyday nonmagnetic uses include colored glass, protective glass and light bulbs.

HISTORY OF NEODYMIUM MAGNETS
Neodymium was first discovered in 1885, but it took almost a century for Neodymium magnets to be invented in 1982. Each magnet is made from pure metal alloys of Neodymium, boron and iron that have been melted or pressed together under high pressure. Melted Neodymium makes a sintered magnet, and the substance can also be produced in a powdered bonded form.
Since the end of the 20th century, Neodymium has been instrumental in miniaturizing many electronics, such as cellphones, microphones, instruments and speakers. Today, Neodymium is used in everything from cars to doors to advertising, making it essential to find a reliable source of Neodymium magnets for sale to support production processes.

Also known simply as a neo magnet, a neodymium magnet is a type of rare-earth magnet that’s comprised of neodymium, iron and boron. Although there are other rare-earth magnets — including samarium cobalt — neodymium is by far the most common. They create a stronger magnetic field, allowing for a superior level of performance. Even if you’ve heard of neodymium magnets, though, there are probably some things you don’t know about these popular rare-earth magnets.
Overview of Neodymium Magnets
Dubbed the world’s strongest permanent magnet, neodymium magnets are magnets made of neodymium. To put their strength into perspective, they can produce magnetic fields with up to 1.4 teslas. Neodymium, of course, is a rare-earth element featuring the atomic number 60. It was discovered in 1885 by chemist Carl Auer von Welsbach. With that said, it wasn’t until nearly a century later until neodymium magnets were invented.
The unparalleled strength of neodymium magnets makes them an excellent choice for a variety of commercial applications, some of which include the following:
- Hard disk drives (HDDs) for computers
- Door locks
- Electric automotive engines
- Electric generators
- Voice coils
- Cordless power tools
- Power steering
- Speakers and headphones
- Retail decouplers
History of Neodymium Magnets
Neodymium magnets were invented in the early 1980s by General Motors and Sumitomo Special Metals. The companies discovered that by combining neodymium with small amounts of iron and boron, they were able to produce a powerful magnet. General Motors and Sumitomo Special Metals then released the world’s first neodymium magnets, offering a cost-effective alternative to other rare-earth magnets on the market.
Neodymium vs Ceramic Magnets
Neodymium Magnets Home Depot
How do neodymium magnets compare to ceramic magnets exactly? Ceramic magnets are undoubtedly cheaper, making them a popular choice for consumer applications. For commercial applications, however, there’s no substitution for neodymium magnets. As previously mentioned, neodymium magnets can create magnetic fields with up to 1.4 teslas. In comparison, ceramic magnets generally produce magnetic fields with just 0.5 to 1 teslas.
Not only are neodymium magnets stronger, magnetically, than ceramic magnets; they are harder as well. Ceramic magnets are brittle, making them susceptible to damage. If you drop a ceramic magnet on the ground, there’s a good chance it will break. Neodymium magnets, on the other hand, are physically harder, so they are less likely to break when dropped or otherwise exposed to stress.
Neodymium Magnets
On the other hand, ceramic magnets are more resistant to corrosion than neodymium magnets. Even when exposed to humidity on a regular basis, ceramic magnets generally won’t corrode or rust.
