Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Contact Surface: Thanks to their flat shape, disc magnets guarantee a significant contact surface with adjoining parts, which can be beneficial in applications requiring a stronger magnetic connection.
Applications in Technology: The magnets are often used in various devices, such as sensors, stepper motors, or speakers, where a thin and wide shape is crucial for their operation.
Mounting: This form's flat shape facilitates mounting, particularly when there's a need to adhere the magnet to another surface.
Design Flexibility: The flat shape of the magnets provides designers with significant flexibility in arranging them in devices, which can be more difficult with magnets of other shapes.
Stability: In some applications, the flat base of a disc magnet can offer better stability, reducing the risk of sliding or rotating. Nevertheless, one should bear in mind that the optimal shape of a magnet depends on the specific project and requirements. In certain cases, other shapes, like cylindrical or spherical, might be a better choice.

Advantages and disadvantages of neodymium magnets NdFeB.
In addition to immense strength, neodymium magnets have the following advantages:
- They do not lose their strength (of the magnet). After about 10 years, their power decreases by only ~1% (theoretically),
- They are highly resistant to demagnetization by external magnetic sources,
- In other words, thanks to the glossy nickel, gold, or silver finish, the element gains an aesthetic appearance,
- They exhibit very high magnetic induction on the surface of the magnet,
- By using an appropriate combination of materials, they can achieve high thermal resistance, allowing them to operate at temperatures up to 230°C and above...
- Due to the option of accurate forming or adaptation to individual needs – neodymium magnets can be produced in various forms and dimensions, which expands the range of their possible uses.
- Key role in the industry of new technologies – are used in HDD drives, electric drive mechanisms, medical apparatus and other modern machines.
Disadvantages of neodymium magnets:
- They are prone to breaking as they are extremely fragile when subjected to a powerful impact. If the magnets are exposed to impacts, it is suggested using magnets in a protective case. The steel housing in the form of a holder protects the magnet from impacts and also increases its overall strength,
- High temperatures can reduce the strength of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent loss in strength (although it is dependent on the shape and size). To prevent this, we offer special magnets marked with the symbol [AH], which are highly resistant to high temperatures. They can operate even at temperatures up to 230°C, making them an ideal solution for applications requiring high-temperature operation,
- They rust in a humid environment - during outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
- Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
- Potential hazard associated with microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting young children. Furthermore, tiny parts of these products can complicate diagnosis in case of swallowing.
Exercise Caution with Neodymium Magnets
Magnets made of neodymium are delicate as well as can easily break and shatter.
Magnets made of neodymium 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. 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.
Neodymium magnets can become demagnetized at high temperatures.
In certain circumstances, Neodymium magnets may experience demagnetization when subjected to high temperatures.
Magnets should not be treated as toys. Therefore, it is not recommended for youngest children to have access to them.
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.
Under no circumstances should neodymium magnets be brought close to GPS and smartphones.
Neodymium magnets produce strong magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
Neodymium magnets can attract to each other, pinch the skin, and cause significant swellings.
Neodymium magnets bounce and also touch each other mutually within a distance of several to almost 10 cm from each other.
You should maintain neodymium magnets at a safe distance from the wallet, computer, and TV.
Neodymium magnets produce intense magnetic fields that 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 videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.
People with pacemakers are advised to avoid neodymium magnets.
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 are the strongest, most remarkable magnets on earth, and the surprising force between them can shock you at first.
Read the information on our website on how to properly utilize neodymium magnets and avoid significant harm to your body and unintentional damage to the magnets.
Dust and powder from neodymium magnets are highly flammable.
Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.
The magnet is coated with nickel. Therefore, exercise caution 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
So you are aware of why neodymium magnets are so dangerous, see the article titled How dangerous are very powerful neodymium magnets?.
