Neodymium magnets MP 41x15x10 / N38 in a ring form are frequently used in various industries due to their specific properties. Thanks to a powerful magnetic field of 8.55 kg, which can be described as force, they are very helpful in applications that require strong magnetism in a compact space. Usage of MP 41x15x10 / N38 magnets include electric motors, generating systems, audio systems, and numerous other devices that use magnets for generating motion or storing energy. Despite their powerful strength, they have a relatively low weight of 61.26 grams, which makes them more practical compared to bulkier alternatives.

Ring magnets work due to their 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. 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 medicine, where they are used in precision diagnostic devices. Their ability to work in high temperatures and precise magnetic field control makes them ideal for technologically advanced applications.

Ring magnets stand out high magnetic strength, resistance to high temperatures, precise control of the magnetic field. Their unique ring form allows for application in devices requiring concentrated magnetic fields. Additionally, these magnets are significantly stronger and more versatile than ferrite counterparts, which has made them popular in advanced technologies and industrial applications.

Ring magnets perform excellently across a wide range of temperatures. Their magnetic properties remain stable, 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 ring magnet of class N52 and N50 is a powerful and strong magnetic piece designed as a ring, providing high force and universal applicability. Attractive price, availability, stability and multi-functionality.

Advantages as well as disadvantages of neodymium magnets NdFeB.

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

They retain their magnetic properties for around ten years – the drop is just ~1% (in theory),
They show superior resistance to demagnetization from outside magnetic sources,
Because of the brilliant layer of gold, the component looks visually appealing,
They exhibit extremely high levels of magnetic induction near the outer area of the magnet,
These magnets tolerate extreme temperatures, often exceeding 230°C, when properly designed (in relation to build),
The ability for accurate shaping and customization to specific needs – neodymium magnets can be manufactured in a wide range of shapes and sizes, which extends the scope of their use cases,
Wide application in advanced technical fields – they find application in HDDs, rotating machines, healthcare devices as well as technologically developed systems,
Relatively small size with high magnetic force – neodymium magnets offer intense magnetic field in compact dimensions, which makes them ideal in compact constructions

Disadvantages of magnetic elements:

They can break when subjected to a strong impact. If the magnets are exposed to physical collisions, it is suggested to place them in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from cracks , and at the same time enhances its overall resistance,
They lose field intensity at high temperatures. Most neodymium magnets experience permanent loss in strength when heated above 80°C (depending on the geometry and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
They rust in a damp environment. If exposed to rain, we recommend using sealed magnets, such as those made of polymer,
The use of a protective casing or external holder is recommended, since machining threads in neodymium magnets is risky,
Health risk linked to microscopic shards may arise, especially if swallowed, which is crucial in the health of young users. It should also be noted that small elements from these products might complicate medical imaging when ingested,
Due to expensive raw materials, their cost is considerably higher,

Handle with Care: Neodymium Magnets

Dust and powder from neodymium magnets are flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. Once crushed into fine powder or dust, this material becomes highly flammable.

Neodymium magnetic are fragile and can easily break as well as shatter.

Neodymium magnetic are highly delicate, and by joining them in an uncontrolled manner, they will break. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.

Do not place neodymium magnets near a computer HDD, TV, and wallet.

Neodymium magnets generate intense magnetic fields that can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also damage devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

Never bring neodymium magnets close to a phone and GPS.

Neodymium magnets produce intense magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

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 not recommended for people with pacemakers.

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

Maintain neodymium magnets far from youngest children.

Neodymium magnets are not toys. Be cautious and make sure no child plays 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.

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 may crack or crumble with careless connecting to each other. You can't move them to each other. At a distance less than 10 cm you should hold them very strongly.

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

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

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.
