Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Contact Surface: Due to their flat shape, disc magnets provide a larger contact surface with other elements, which is beneficial in applications needing a stronger magnetic connection.
Applications in Technology: The magnets are often utilized in many devices, such as sensors, stepper motors, or speakers, where a thin and wide shape is essential 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 disc shape of the magnets allows designers with greater flexibility in placing them in constructions, which can be more difficult with magnets of other shapes.
Stability: In some applications, the flat base of a disc magnet may offer better stability, reducing the risk of shifting or rotating. However, it's important to remember that the optimal shape of a magnet depends on the particular use and requirements. In some cases, other shapes, like cylindrical or spherical, might be more suitable.

Advantages as well as 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 strength decreases by only ~1% (theoretically),
- They are extremely resistant to demagnetization by external magnetic field,
- In other words, thanks to the glossy nickel, gold, or silver finish, the element gains an visually attractive appearance,
- They possess very high magnetic induction on the surface of the magnet,
- Thanks to their high temperature resistance, they can operate (depending on the shape) even at temperatures up to 230°C and above...
- Thanks to the flexibility in shaping or the ability to adapt to specific requirements – neodymium magnets can be produced in a wide range of shapes and sizes, which enhances their versatility in applications.
- Key role in modern technologies – are used in HDD drives, electric drive mechanisms, medical devices and very modern machines.
Disadvantages of neodymium magnets:
- They can break when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a steel housing. 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 power of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent reduction 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,
- The use of a cover or a magnetic holder is recommended due to the limited possibilities of manufacturing threads or complex shapes in the magnet
- Possible danger associated with microscopic parts of magnets pose a threat, in case of ingestion, which becomes significant in the context of children's health. It's also worth noting that tiny parts of these devices are able to complicate diagnosis when they are in the body.
We Recommend Caution with Neodymium Magnets
Neodymium magnets are over 10 times stronger than ferrite magnets (the ones in speakers), and their power can shock you.
On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.
Neodymium magnets can become demagnetized at high temperatures.
Although magnets have shown to retain their effectiveness up to 80°C or 175°F, this temperature may vary depending on the type of material, shape, and intended use of the magnet.
Neodymium Magnets can attract to each other due to their immense internal force, causing the skin and other body parts to get pinched and resulting in significant injuries.
If have a finger between or on the path of attracting magnets, there may be a severe cut or a fracture.
Do not give neodymium magnets to youngest children.
Neodymium magnets are not toys. You cannot allow them to become toys for children. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.
Keep neodymium magnets away from the wallet, computer, and TV.
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. You should especially avoid placing neodymium magnets near electronic devices.
Neodymium magnetic are noted for their fragility, which can cause them to crumble.
Neodymium magnetic are extremely delicate, and by joining them in an uncontrolled manner, they will crumble. 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.
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.
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.
Keep neodymium magnets away from people with pacemakers.
Neodymium magnets generate strong magnetic fields. As a result, they 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.
Avoid contact with neodymium magnets if you have a nickel allergy.
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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.
In order for you to know how powerful neodymium magnets are and why they are so dangerous, see the article - Dangerous strong neodymium magnets.
