Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Contact Surface: Thanks to their flat shape, disc magnets provide a larger contact surface with other elements, which can be beneficial in applications requiring a stronger magnetic connection.
Applications in Technology: These magnets are often utilized in different devices, like sensors, stepper motors, or speakers, where a flat shape is important for their operation.
Mounting: This form's flat shape makes mounting, particularly when it's necessary to adhere the magnet to a surface.
Design Flexibility: The disc shape of the magnets allows designers with greater flexibility in arranging them in devices, which can be more difficult with magnets of other shapes.
Stability: In certain applications, the flat base of a disc magnet can provide better stability, reducing the risk of shifting or rotating. It should be noted that the optimal shape of a magnet depends on the specific application and requirements. In some cases, other shapes, like cylindrical or spherical, might be a better choice.

Advantages as well as disadvantages of neodymium magnets NdFeB.
Apart from immense power, neodymium magnets have the following advantages:
- They do not lose their power (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,
- By using an appropriate combination of materials, they can achieve high thermal resistance, allowing them to operate at temperatures up to 230°C and above...
- Due to the option of accurate forming and adaptation to individual needs – neodymium magnets can be produced in a wide range of shapes and sizes, which enhances their versatility in applications.
- Key role in the industry of new technologies – find application in computer drives, electric motors, medical apparatus or very highly developed apparatuses.
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 metal holder. 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 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 form 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,
- 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
- Health risk arising from small pieces of magnets can be dangerous, when accidentally ingested, which becomes significant in the context of child safety. Furthermore, tiny parts of these magnets can hinder the diagnostic process in case of swallowing.
Be Cautious with Neodymium Magnets
Neodymium magnets can demagnetize 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.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times stronger, and their power can shock you.
Familiarize yourself with our information to correctly handle these magnets and avoid significant injuries to your body and prevent disruption to the magnets.
Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.
Neodymium magnets generate strong magnetic fields that can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also damage videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.
Keep neodymium magnets as far away as possible from GPS and smartphones.
Strong 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 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.
Magnets may crack or alternatively crumble with careless connecting to each other. Remember not to approach them to each other or hold them firmly in hands at a distance less than 10 cm.
The magnet is coated with nickel - be careful if you have an 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.
Magnets made of neodymium are extremely fragile, resulting in shattering.
Neodymium magnetic are delicate as well as will crack if allowed to collide with each other, even from a distance of a few centimeters. 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.
Neodymium magnets are not recommended for people with pacemakers.
Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.
Do not give neodymium magnets to 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.
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.
