Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Contact Surface: Due 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: They are often used in different 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 makes mounting, particularly when there's a need to adhere the magnet to a surface.
Design Flexibility: The disc shape of the magnets provides designers with greater flexibility in placing 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, may be more suitable.

Advantages and disadvantages of neodymium magnets NdFeB.
Apart from 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,
- By applying a shiny coating of nickel, gold, or silver, the element gains an aesthetic appearance,
- They possess 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 shape) 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 many variants of shapes or sizes, which expands the range of their possible uses.
- Wide application in modern technologies – are utilized in computer drives, electric drive mechanisms, medical equipment or various technologically advanced devices.
Disadvantages of neodymium magnets:
- They can break as they are extremely fragile when subjected to a strong impact. If the magnets are exposed to impacts, it is suggested using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts and simultaneously increases its overall strength,
- They lose strength at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the form and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
- Due to their susceptibility to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
- 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 to health from tiny fragments of magnets can be dangerous, if swallowed, which becomes significant in the context of children's health. It's also worth noting that miniscule components of these magnets can be problematic in medical diagnosis in case of swallowing.
Exercise Caution with Neodymium Magnets
The magnet is coated with nickel - be careful 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.
Neodymium magnets are the most powerful magnets ever invented. Their strength can surprise 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.
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.
Keep neodymium magnets away from the wallet, computer, and TV.
Strong magnetic fields emitted by neodymium magnets can damage 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.
It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.
Magnets will crack or alternatively crumble with careless joining to each other. Remember not to move them to each other or have them firmly in hands at a distance less than 10 cm.
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 happens because such devices have a function to deactivate them in a magnetic field.
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. They can be a significant choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing significant injuries, and even death.
Neodymium magnetic are particularly fragile, resulting in shattering.
In the event of a collision between two neodymium magnets, it can result in them getting chipped. They are coated with a shiny nickel plating similar to steel, but they are not as hard. 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.
So that know how strong neodymium magnets are and why they are so dangerous, read the article - Dangerous powerful neodymium magnets.
