Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Contact Surface: Due to their flat shape, disc magnets guarantee a significant contact surface with other elements, which can be beneficial in applications needing a stronger magnetic connection.
Applications in Technology: The magnets are often utilized in various devices, such as sensors, stepper motors, or speakers, where a flat shape is essential for their operation.
Mounting: This form's flat shape makes mounting, particularly when you need to adhere the magnet to another surface.
Design Flexibility: The disc shape of the magnets allows designers with significant flexibility in placing them in devices, which can sometimes be more difficult with magnets of more complex shapes.
Stability: In some applications, the flat base of a disc magnet may offer better stability, reducing the risk of sliding 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.
In addition to immense strength, neodymium magnets have the following advantages:
- They do not lose strength over time. After 10 years, their strength decreases by only ~1% (theoretically),
- They are exceptionally resistant to demagnetization caused by an external magnetic field,
- Thanks to the shiny finish and nickel, gold, or silver coating, they have an aesthetic appearance,
- They have very 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...
- 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.
- Significant importance in the industry of new technologies – are used in HDD drives, electric drive mechanisms, medical apparatus or very highly developed apparatuses.
Disadvantages of neodymium magnets:
- They can break as they are fragile when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a metal holder. The steel housing in the form of a holder protects the magnet from impacts and also increases its overall strength,
- They lose power 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,
- They rust in a humid environment. For outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
- 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 are risky, when accidentally ingested, which is particularly important in the aspect of protecting young children. It's also worth noting that tiny parts of these products are able to be problematic in medical diagnosis after entering the body.
Safety Guidelines with Neodymium Magnets
Neodymium magnetic are noted for their fragility, which can cause them to shatter.
Neodymium magnets are characterized by considerable fragility. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. At the moment of connection between the magnets, small metal fragments can be dispersed in different directions.
Do not bring neodymium magnets 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.
If you have a nickel allergy, avoid contact with neodymium magnets.
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.
Dust and powder from neodymium magnets are flammable.
Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. Once crushed into fine powder or dust, this material becomes highly flammable.
Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.
Magnetic fields generated by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other similar devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
Neodymium magnets are the strongest magnets ever invented. Their strength can surprise you.
Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.
Neodymium Magnets can attract to each other, pinch the skin, and cause significant swellings.
Neodymium magnets will jump and contact together within a distance of several to around 10 cm from each other.
Neodymium magnets can demagnetize at high temperatures.
Despite the general resilience of magnets, their ability to retain their magnetic strength can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.
Neodymium magnets should not be around 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 are not recommended for 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.
