Small and Large Neodymium Magnets

Neodymium magnets offer a cost-efficient and effective solution for a wide variety of applications. These magnets are the choice for many industries such as packaging, marketing, and manufacturing. Our range of Neodymium magnetic strips offers a great deal of strength in a small size, which makes them perfect when working with applications with size constraints.

Our collection of small and large Neodymium magnets are susceptible to demagnetization at elevated temperatures. We will work with you to understand the operating parameters and whether a Neodymium magnet or other one constructed of another material is best suited for your needs.

The powerful nature of these magnets requires careful handling - small magnets can shatter when allowed to attract one another from a distance and large magnets can cause pain or even bodily injury when not handled properly.

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.
