Neodymium magnets MP 24x16x2 / N38 in a ring-shaped form are frequently used in various industries due to their unique properties. Thanks to a powerful magnetic field of 1.77 kg, which can be described as lifting capacity, they are extremely useful in applications that require strong magnetism in a compact space. Usage of MP 24x16x2 / N38 magnets include electrical mechanisms, generators, sound devices, and many other devices that use magnets for generating motion or energy storage. Despite their powerful strength, they have a relatively low weight of 3.77 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 generating a strong and precise magnetic field. This field is ideal for applications in systems requiring motion control. Additionally, 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, 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.

Their uniqueness comes from 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. Moreover, these magnets are significantly stronger and more versatile than ferrite counterparts, which has made them popular in advanced technologies and industrial applications.

Thanks to their resistance to high temperatures, ring magnets operate reliably even in tough conditions. 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 magnet of class N50 and N52 is a powerful and highly strong metallic component designed as a ring, featuring strong holding power and universal applicability. Competitive price, availability, stability and versatility.

Advantages as well as disadvantages of neodymium magnets NdFeB.

In addition to their immense field intensity, neodymium magnets offer the following advantages:

They retain their attractive force for almost 10 years – the drop is just ~1% (in theory),
They remain magnetized despite exposure to magnetic surroundings,
The use of a mirror-like gold surface provides a smooth finish,
They have very high magnetic induction on the surface of the magnet,
These magnets tolerate high temperatures, often exceeding 230°C, when properly designed (in relation to profile),
The ability for precise shaping and adaptation to specific needs – neodymium magnets can be manufactured in a wide range of shapes and sizes, which extends the scope of their use cases,
Important function in modern technologies – they serve a purpose in data storage devices, electromechanical systems, diagnostic apparatus as well as sophisticated instruments,
Thanks to their efficiency per volume, small magnets offer high magnetic performance, while occupying minimal space,

Disadvantages of magnetic elements:

They are prone to breaking when subjected to a strong impact. If the magnets are exposed to mechanical hits, we recommend in a protective case. The steel housing, in the form of a holder, protects the magnet from damage and additionally strengthens its overall robustness,
They lose magnetic force at high temperatures. Most neodymium magnets experience permanent decline in strength when heated above 80°C (depending on the form and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
Due to corrosion risk in humid conditions, it is wise to use sealed magnets made of synthetic coating for outdoor use,
Using a cover – such as a magnetic holder – is advised due to the difficulty in manufacturing complex structures directly in the magnet,
Safety concern related to magnet particles may arise, when consumed by mistake, which is crucial in the family environments. Furthermore, tiny components from these devices might disrupt scanning if inside the body,
Due to a complex production process, their cost is relatively high,

Safety Precautions

Neodymium magnets should not be in the vicinity children.

Remember that neodymium magnets are not toys. Do not allow children to play 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.

Neodymium magnetic are fragile and can easily crack and shatter.

In the event of a collision between two neodymium magnets, it can result in them getting chipped. Despite being made of metal as well as coated with a shiny nickel plating, they are not as hard as steel. 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.

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.

Neodymium magnets bounce and touch each other mutually within a radius of several to around 10 cm from each other.

Keep neodymium magnets away from 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.

Neodymium magnets can demagnetize at high temperatures.

Although magnets are generally resilient, their ability to retain their magnetic strength 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 placed 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, or other devices. They can also destroy devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

Neodymium magnets are the most powerful magnets ever created, and their power can surprise you.

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

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

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

The magnet coating is made of nickel, so be cautious 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.

Dust and powder from neodymium magnets are flammable.

Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Pay attention!
