Neodymium magnets MP 10x6x4 / N38 in a ring form are regularly used in various industries due to their specific properties. Thanks to a powerful magnetic field of 1.37 kg, which can be described as strength, they are key in applications that require high magnetic power in a relatively small area. Applications of MP 10x6x4 / N38 magnets include electric motors, generating systems, audio systems, and many other devices that use magnets for generating motion or storing energy. Despite their significant strength, they have a relatively low weight of 3.77 grams, which makes them more convenient to use 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 the creation of a concentrated magnetic field in a specific direction. This makes them perfect for devices such as stepper motors or industrial robots. Additionally, ring magnets are resistant to demagnetization.

Ring magnets have a wide range of applications in many industries, such as production of electronic devices, such as speakers and electric motors, the automotive industry, e.g., in the construction of 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 high magnetic strength, resistance to high temperatures, precise control of the magnetic field. Thanks to their ring shape allows for application in devices requiring concentrated magnetic fields. Additionally, 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, until the Curie temperature is exceeded, which for neodymium magnets is around 80°C. They are more resistant to loss of magnetism than traditional ferrite magnets. For this reason, they are ideal for applications in the automotive industry, robotics, and devices requiring operation in changing or extreme environmental conditions.

A neodymium ring magnet N52 and N50 is a powerful and highly strong magnetic product in the form of a ring, that provides high force and universal application. Attractive price, availability, ruggedness and broad range of uses.

Advantages as well as disadvantages of neodymium magnets NdFeB.

In addition to their remarkable strength, neodymium magnets offer the following advantages:

They retain their attractive force for around 10 years – the drop is just ~1% (according to analyses),
Their ability to resist magnetic interference from external fields is notable,
Thanks to the polished finish and silver coating, they have an elegant appearance,
They have exceptional magnetic induction on the surface of the magnet,
With the right combination of materials, they reach increased thermal stability, enabling operation at or above 230°C (depending on the structure),
The ability for accurate shaping and adaptation to individual needs – neodymium magnets can be manufactured in multiple variants of geometries, which amplifies their functionality across industries,
Wide application in cutting-edge sectors – they find application in computer drives, rotating machines, diagnostic apparatus or even high-tech tools,
Compactness – despite their small size, they deliver powerful magnetism, making them ideal for precision applications

Disadvantages of rare earth magnets:

They may fracture when subjected to a sudden impact. If the magnets are exposed to external force, we recommend in a protective case. The steel housing, in the form of a holder, protects the magnet from damage and reinforces its overall robustness,
High temperatures may significantly reduce the strength of neodymium magnets. Typically, above 80°C, they experience permanent weakening in performance (depending on height). To prevent this, we offer heat-resistant magnets marked [AH], capable of working up to 230°C, which makes them perfect for high-temperature use,
Magnets exposed to wet conditions can oxidize. Therefore, for outdoor applications, we advise waterproof types made of coated materials,
The use of a protective casing or external holder is recommended, since machining multi-axis shapes in neodymium magnets is difficult,
Possible threat related to magnet particles may arise, when consumed by mistake, which is crucial in the health of young users. Furthermore, minuscule fragments from these assemblies may interfere with diagnostics when ingested,
High unit cost – neodymium magnets are pricier than other types of magnets (e.g., ferrite), which may limit large-scale applications

Safety Precautions

The magnet is coated with nickel - be careful if you have an allergy.

Studies show a small percentage of people have allergies to certain metals, including 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 the strongest, most remarkable magnets on earth, and the surprising force between them can surprise you at first.

Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.

Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.

Strong magnetic fields emitted by neodymium magnets can damage 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.

Maintain neodymium magnets away from children.

Remember that neodymium magnets are not toys. Be cautious and make sure no child plays with them. In the case of swallowing multiple magnets simultaneously, they can attract to each other through the intestinal walls. In the worst case scenario, this can lead to death.

People with pacemakers are advised to avoid neodymium magnets.

Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This is because many of these devices are equipped with a function that deactivates the device in a magnetic field.

Neodymium magnets are especially delicate, resulting in shattering.

In the event of a collision between two neodymium magnets, it can result in them getting chipped. They are coated with a shiny nickel plating similar to steel, but they are not as hard. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.

Dust and powder from neodymium magnets are flammable.

Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.

It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.

Magnets will attract each other within a distance of several to around 10 cm from each other. Remember not to insert fingers between magnets or in their path when attract. Magnets, depending on their size, can even cut off a finger or alternatively there can be a severe pressure or even a fracture.

Under no circumstances should neodymium magnets be brought close to GPS and smartphones.

Magnetic fields can interfere with compasses and magnetometers used in aviation and maritime navigation, as well as internal compasses of smartphones and GPS devices. There are neodymium magnets in every smartphone, for example, in the microphone and speakers.

Neodymium magnets can demagnetize at high temperatures.

Although magnets have shown to retain their effectiveness up to 80°C or 175°F, this temperature may vary depending on the type of material, shape, and intended use of the magnet.

Exercise caution!
