Due to unique properties, neodymium magnet MP 36.2x11/6x7.5 / N38 in a ring form finds extensive use in various industries. Thanks to a powerful magnetic field of 3.63 kg, which can be described as force, they are very helpful in applications that require high magnetic power in a compact space. Applications of MP 36.2x11/6x7.5 / N38 magnets include electrical mechanisms, generating systems, audio systems, and numerous other devices that use magnets for generating motion or storing energy. Despite their significant strength, they have a relatively low weight of 48.95 grams, which makes them more practical compared to heavier alternatives.

The operation of ring magnets results from their unique atomic structure. Their properties arise from a controlled production process, including sintering and magnetization, which allows for the creation of a concentrated magnetic field in a specific direction. This field is ideal for applications in systems requiring motion control. Moreover, their resistance to high temperatures and demagnetization makes them indispensable in industry.

Ring magnets have a wide range of applications in many industries, such as electronics, e.g., in the production of speakers or 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 indispensable in challenging industrial conditions.

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. Moreover, these magnets are more durable than traditional ferrite magnets, making them an ideal choice in the automotive, electronics, and medical industries.

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. 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 highly strong metallic component in the form of a ring, providing strong holding power and broad usability. Attractive price, fast shipping, ruggedness and broad range of uses.

Advantages and disadvantages of neodymium magnets NdFeB.

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

Their magnetic field is durable, and after around 10 years, it drops only by ~1% (theoretically),
They show superior resistance to demagnetization from outside magnetic sources,
Because of the lustrous layer of gold, the component looks visually appealing,
They have exceptional magnetic induction on the surface of the magnet,
They are suitable for high-temperature applications, operating effectively at 230°C+ due to advanced heat resistance and form-specific properties,
The ability for precise shaping or adjustment to individual needs – neodymium magnets can be manufactured in many forms and dimensions, which extends the scope of their use cases,
Wide application in advanced technical fields – they serve a purpose in hard drives, electric motors, healthcare devices or even technologically developed systems,
Relatively small size with high magnetic force – neodymium magnets offer impressive pulling strength in small dimensions, which makes them useful in compact constructions

Disadvantages of neodymium magnets:

They are prone to breaking when subjected to a heavy impact. If the magnets are exposed to mechanical hits, we recommend in a steel housing. The steel housing, in the form of a holder, protects the magnet from damage while also enhances its overall robustness,
Magnets lose power when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible magnetic decay (influenced by the magnet’s structure). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
Magnets exposed to damp air can rust. Therefore, for outdoor applications, it's best to use waterproof types made of plastic,
Limited ability to create internal holes in the magnet – the use of a mechanical support is recommended,
Possible threat related to magnet particles may arise, if ingested accidentally, which is crucial in the family environments. It should also be noted that miniature parts from these devices might complicate medical imaging when ingested,
In cases of tight budgets, neodymium magnet cost may not be economically viable,

Handle Neodymium Magnets Carefully

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

The strong magnetic field generated by neodymium magnets can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also destroy videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

The magnet coating contains nickel, so be cautious if you have a nickel 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 can become demagnetized at high temperatures.

Despite the general resilience of magnets, their ability to maintain their magnetic potency can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.

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

Magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.

Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.

Magnets will attract each other within a distance of several to around 10 cm from each other. Don't put your fingers in the path of magnet attraction, because a major injury may occur. Depending on how large the neodymium magnets are, they can lead to a cut or alternatively a fracture.

Neodymium magnets are over 10 times more powerful than ferrite magnets (the ones in speakers), and their power can surprise you.

Familiarize yourself with our information to correctly handle these magnets and avoid significant injuries to your body and prevent damage to the magnets.

It is essential to maintain neodymium magnets away from children.

Remember that neodymium magnets are not toys. Do not allow children to play with them. Small magnets can pose a serious choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing significant injuries, and even death.

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 are not recommended for people with pacemakers.

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 highly delicate, they easily break as well as can become damaged.

Neodymium magnets are characterized by significant fragility. Magnets made of neodymium are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of connection between the magnets, small metal fragments can be dispersed in different directions.
