Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Contact Surface: Thanks to their flat shape, disc magnets guarantee a larger contact surface with adjoining parts, which can be beneficial in applications needing a stronger magnetic connection.
Applications in Technology: These magnets are often employed in various devices, like sensors, stepper motors, or speakers, where a flat shape is crucial for their operation.
Mounting: The flat form's flat shape makes mounting, particularly when you need to adhere the magnet to a surface.
Design Flexibility: The disc shape of the magnets provides designers with greater flexibility in arranging them in devices, which can be more difficult with magnets of more complex shapes.
Stability: In some applications, the flat base of a disc magnet can offer better stability, minimizing 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.
Apart from immense power, neodymium magnets have the following advantages:
- They do not lose power over time. After about 10 years, their strength decreases by only ~1% (theoretically),
- They are highly resistant to demagnetization by external magnetic field,
- In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
- They exhibit extremely high magnetic induction on the surface of the magnet,
- By using an appropriate combination of materials, they can achieve significant thermal resistance, allowing them to operate at temperatures up to 230°C and above...
- The ability for precise shaping and customization to specific needs – neodymium magnets can be produced in various forms and dimensions, which amplifies their universality in usage.
- Key role in the industry of new technologies – are utilized in HDD drives, electric motors, medical equipment and other advanced devices.
Disadvantages of neodymium magnets:
- They can break as they are extremely fragile 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 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 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,
- 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
- Possible danger arising from small pieces of magnets can be dangerous, if swallowed, which is crucial in the aspect of protecting young children. It's also worth noting that miniscule components of these magnets have the potential to complicate diagnosis when they are in the body.
Handle with Care: Neodymium Magnets
Neodymium magnetic are extremely fragile, leading to shattering.
Neodymium magnets are characterized by considerable fragility. Magnets made of neodymium 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 are the most powerful, most remarkable magnets on earth, and the surprising force between them can surprise you at first.
Familiarize yourself with our information to correctly handle these magnets and avoid significant injuries to your body and prevent disruption to the magnets.
Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.
Neodymium magnets jump and also touch each other mutually within a distance of several to around 10 cm from each other.
Keep neodymium magnets away from youngest 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.
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.
Keep neodymium magnets away from GPS and smartphones.
Magnetic fields can interfere with compasses and magnetometers used in aviation and maritime navigation, as well as internal compasses of smartphones and GPS devices. There are neodymium magnets in every smartphone, for example, in the microphone and speakers.
Neodymium magnets can become demagnetized at high temperatures.
Although magnets have demonstrated their effectiveness up to 80°C or 175°F, the temperature can vary depending on the type, shape, and intended use of the specific magnet.
Dust and powder from neodymium magnets are highly 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 TV, wallet, and computer HDD.
The strong magnetic field generated by neodymium magnets can damage 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. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.
Avoid contact with neodymium magnets 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.
