Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Contact Surface: Thanks to their flat shape, disc magnets provide a significant contact surface with adjoining parts, which can be beneficial in applications needing a stronger magnetic connection.
Applications in Technology: They are often used in various devices, such as sensors, stepper motors, or speakers, where a thin and wide shape is essential for their operation.
Mounting: Their flat shape facilitates mounting, especially when you need to adhere the magnet to another surface.
Design Flexibility: The flat shape of the magnets provides designers with greater 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 provide better stability, minimizing the risk of sliding or rotating. It should be noted that the optimal shape of a magnet is dependent on the specific project and requirements. In some cases, other shapes, like cylindrical or spherical, may be a better choice.

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 protect against demagnetization caused by external magnetic field very well,
- In other words, thanks to the glossy nickel, gold, or silver finish, the element gains an visually attractive appearance,
- They have 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...
- The ability for precise shaping and customization to specific needs – neodymium magnets can be produced in various forms and dimensions, which expands the range of their possible uses.
- Key role in advanced technologically fields – find application in HDD drives, electric motors, medical devices and various technologically advanced devices.
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 steel housing. 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 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,
- 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
- Health risk to health from tiny fragments of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting young children. Furthermore, tiny parts of these devices can complicate diagnosis when they are in the body.
Be Cautious with Neodymium Magnets
Neodymium magnets are over 10 times stronger than ferrite magnets (the ones in speakers), and their power 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 as far away as possible from 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.
Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.
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, etc. devices. They can also destroy videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
Dust and powder from neodymium magnets are flammable.
Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.
Neodymium magnets can demagnetize at high temperatures.
In certain circumstances, Neodymium magnets can lose their magnetism when subjected to high temperatures.
Neodymium magnetic are delicate and can easily break and get damaged.
Neodymium magnetic are extremely delicate, and by joining them in an uncontrolled manner, they will crumble. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard 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.
People with pacemakers are advised to avoid neodymium magnets.
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.
Magnets are not toys, children should not play with them.
Neodymium magnets are not toys. Be cautious and make sure no child plays 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.
If you have a nickel allergy, avoid contact with neodymium magnets.
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 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 will bounce and touch together within a distance of several to around 10 cm from each other.
