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 other elements, which can be beneficial in applications requiring a stronger magnetic connection.
Applications in Technology: They are often utilized in different devices, like sensors, stepper motors, or speakers, where a thin and wide shape is essential for their operation.
Mounting: Their flat shape makes mounting, especially when you need to adhere the magnet to a surface.
Design Flexibility: The flat shape of the magnets allows designers with greater flexibility in placing them in devices, which can sometimes be more difficult with magnets of other shapes.
Stability: In some applications, the flat base of a disc magnet can offer better stability, minimizing the risk of sliding or rotating. Nevertheless, one should bear in mind that the optimal shape of a magnet depends on the specific project 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 power, 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 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 exhibit extremely 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 and the ability to adapt to specific requirements – neodymium magnets can be produced in various forms and dimensions, which expands the range of their possible uses.
- Key role in advanced technologically fields – are utilized in hard drives, electric motors, medical apparatus and other advanced devices.
Disadvantages of neodymium magnets:
- They are fragile when subjected to a powerful 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,
- 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 - during 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 arising from small pieces of magnets pose a threat, in case of ingestion, which is crucial in the context of child safety. Furthermore, miniscule components of these magnets can complicate diagnosis when they are in the body.
Handle Neodymium Magnets Carefully
Never bring neodymium magnets close to a phone and GPS.
Magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
Neodymium magnets are incredibly delicate, they easily fall apart as well as can crumble.
Magnets made of neodymium 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.
Neodymium magnets are among the most powerful magnets on Earth. The astonishing force they generate between each other 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.
Neodymium Magnets can attract to each other, pinch the skin, and cause significant injuries.
Magnets attract each other within a distance of several to about 10 cm from each other. Don't put your fingers in the path of magnet attraction, because a serious injury may occur. Depending on how massive the neodymium magnets are, they can lead to a cut or a fracture.
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.
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.
Magnets are not toys, children should not play with them.
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.
The magnet coating contains nickel, so be cautious 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.
Neodymium magnets can demagnetize at high temperatures.
Although magnets are generally resilient, their ability to maintain their magnetic potency can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.
Do not place neodymium magnets 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.
