Due to unique properties, MP 60x20x5 / N38 in a ring form finds extensive use in various industries. Thanks to a powerful magnetic field of 5.7 kg, which can be described as force, they are key in applications that require high magnetic power in a relatively small area. Usage of MP 60x20x5 / N38 magnets include electric motors, generators, audio systems, and many other devices that use magnets for generating motion or storing energy. Despite their significant strength, they have a comparatively low weight of 47.12 grams, which makes them more practical compared to heavier alternatives.

The operation of ring magnets results from their unique atomic structure. In the production process, neodymium atoms are arranged appropriately, which allows for generating a strong and precise magnetic field. This field is ideal for applications in systems requiring motion control. Moreover, their resistance to high temperatures and demagnetization makes them indispensable in industry.

They are used in various fields of technology and industry, such as production of electronic devices, such as speakers and electric motors, automotive, where they are used in brushless electric motors, and medical equipment, e.g., in scanning devices. Thanks to their temperature resistance and precision makes them ideal for technologically advanced applications.

Ring magnets stand out extraordinary pulling power, resistance to high temperatures, and precision in generating the magnetic field. Thanks to their ring shape allows for effective use in devices such as motors or speakers. Moreover, these magnets are more durable than traditional ferrite magnets, which has made them popular in advanced technologies and industrial applications.

Ring magnets perform excellently across a wide range of temperatures. They do not lose their magnetic properties, as long as the temperature does not exceed the Curie point. Compared to other types of magnets, ring magnets show greater resistance to demagnetization. Because of this, they are ideal for applications in the automotive industry, robotics, and devices requiring operation in changing or extreme environmental conditions.

A neodymium magnet of class N52 and N50 is a strong and powerful magnetic product shaped like a ring, featuring strong holding power and universal applicability. Very good price, fast shipping, ruggedness and versatility.

Advantages as well as disadvantages of neodymium magnets NdFeB.

Besides their durability, neodymium magnets are valued for these benefits:

Their power is maintained, and after approximately 10 years, it drops only by ~1% (theoretically),
Their ability to resist magnetic interference from external fields is among the best,
Thanks to the glossy finish and silver coating, they have an visually attractive appearance,
Magnetic induction on the surface of these magnets is impressively powerful,
With the right combination of magnetic alloys, they reach excellent thermal stability, enabling operation at or above 230°C (depending on the form),
With the option for fine forming and precise design, these magnets can be produced in numerous shapes and sizes, greatly improving application potential,
Important function in cutting-edge sectors – they serve a purpose in computer drives, electric motors, clinical machines along with high-tech tools,
Relatively small size with high magnetic force – neodymium magnets offer intense magnetic field in small dimensions, which makes them ideal in miniature devices

Disadvantages of NdFeB magnets:

They are fragile when subjected to a powerful impact. If the magnets are exposed to shocks, we recommend in a steel housing. The steel housing, in the form of a holder, protects the magnet from damage while also reinforces its overall durability,
They lose strength at elevated temperatures. Most neodymium magnets experience permanent reduction in strength when heated above 80°C (depending on the dimensions and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
Magnets exposed to wet conditions can oxidize. Therefore, for outdoor applications, we recommend waterproof types made of rubber,
Limited ability to create complex details in the magnet – the use of a housing is recommended,
Possible threat linked to microscopic shards may arise, in case of ingestion, which is notable in the context of child safety. Additionally, small elements from these assemblies have the potential to hinder health screening when ingested,
Higher purchase price is an important factor to consider compared to ceramic magnets, especially in budget-sensitive applications

Precautions

Dust and powder from neodymium magnets are flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Neodymium magnets can demagnetize at high temperatures.

Despite the fact that magnets have been found to maintain their efficacy up to temperatures of 80°C or 175°F, it's essential to consider that this threshold may fluctuate depending on the magnet's type, configuration, and intended usage.

Neodymium magnetic are particularly delicate, resulting in shattering.

Neodymium magnetic are highly delicate, and by joining them in an uncontrolled manner, they will crumble. Neodymium magnets are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of collision between the magnets, sharp metal fragments can be dispersed in different directions.

Neodymium magnets should not be near people with pacemakers.

Neodymium magnets produce strong magnetic fields that can interfere with the operation of a heart pacemaker. However, if the magnetic field does not affect the device, it can damage its components or deactivate the device when it is in a magnetic field.

The magnet is coated with nickel. Therefore, exercise caution if you have an allergy.

Studies clearly indicate a small percentage of people who suffer from metal allergies such as nickel. An allergic reaction often manifests as skin redness and rash. If you have a nickel allergy, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.

Neodymium magnets are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.

If joining of neodymium magnets is not under control, at that time they may crumble and also crack. You can't move them to each other. At a distance less than 10 cm you should hold them extremely strongly.

Never bring neodymium magnets close to a phone and GPS.

Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.

Neodymium magnets should not be around youngest children.

Neodymium magnets are not toys. Do not allow children to play with them. They can be a significant choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing significant injuries, and even death.

You should maintain neodymium magnets at a safe distance from the wallet, computer, and TV.

Strong magnetic fields emitted by neodymium magnets can destroy magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.

Neodymium magnets are among the most powerful magnets on Earth. The astonishing force they generate between each other can shock you.

To use magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.
