Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Contact Surface: Thanks to their flat shape, disc magnets provide a significant contact surface with other elements, which is beneficial in applications requiring a stronger magnetic connection.
Applications in Technology: The magnets are often employed in different devices, such as sensors, stepper motors, or speakers, where a flat shape is important for their operation.
Mounting: This form's flat shape facilitates mounting, especially when you need to adhere the magnet to a surface.
Design Flexibility: The flat shape of the magnets gives designers with significant flexibility in placing 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 provide better stability, minimizing the risk of shifting or rotating. It should be noted that the optimal shape of a magnet depends on the particular use and requirements. In certain cases, other shapes, like cylindrical or spherical, might be a better choice.

Advantages as well as disadvantages of neodymium magnets NdFeB.
Apart from immense strength, neodymium magnets have the following advantages:
- They do not lose strength over time - after 10 years, their power decreases by only ~1% (theoretically),
- They protect against demagnetization caused by external magnetic field extremely well,
- By applying a shiny coating of nickel, gold, or silver, the element gains an aesthetic appearance,
- They exhibit very high magnetic induction on the surface of the magnet,
- Magnetic neodymium magnets are characterized by very high magnetic induction on the surface of the magnet and can operate (depending on the form) even at temperatures of 230°C or higher...
- Due to the option of accurate forming or adaptation to individual needs – neodymium magnets can be produced in a wide range of shapes and sizes, which enhances their versatility in applications.
- Key role in the industry of new technologies – are used in hard drives, electric drive mechanisms, medical devices and very highly developed apparatuses.
Disadvantages of neodymium magnets:
- They are fragile when subjected to a strong impact. If the magnets are exposed to impacts, we recommend using magnets in a protective case. The steel housing in the form of a holder protects the magnet from impacts and at the same time 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 reduction in strength (although it is dependent on the form 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,
- Magnets exposed to a humid environment can corrode. Therefore, when using them outdoors, we suggest using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
- The use of a cover - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
- Health risk arising from small pieces of magnets pose a threat, when accidentally ingested, which is crucial in the context of children's health. Additionally, tiny parts of these magnets have the potential to complicate diagnosis after entering the body.
Precautions
Neodymium magnets can attract to each other, pinch the skin, and cause significant injuries.
In the case of holding a finger in the path of a neodymium magnet, in such a case, a cut or a fracture may occur.
Neodymium magnets are the strongest, most remarkable magnets on the planet, and the surprising force between them can surprise 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 disruption to the magnets.
If you have a nickel allergy, avoid contact with neodymium magnets.
Studies clearly indicate a small percentage of people who suffer from metal allergies such as 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.
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.
Under no circumstances should neodymium magnets be brought close to GPS and smartphones.
Neodymium magnets generate strong magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
Do not place neodymium magnets near a computer HDD, TV, and wallet.
Strong magnetic fields emitted by neodymium magnets can destroy 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.
Keep neodymium magnets away from 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.
Maintain neodymium magnets far from youngest children.
Not all neodymium magnets are toys, so do not let children play with them. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.
Neodymium magnets can become demagnetized at high temperatures.
Whilst Neodymium magnets can demagnetize at high temperatures, it's important to note that the extent of this effect can vary based on factors such as the magnet's material, shape, and intended application.
Neodymium magnets are particularly delicate, resulting in damage.
Neodymium magnets are delicate and will crack if allowed to collide with each other, even from a distance of a few centimeters. 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.
