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: These magnets are often employed in many devices, like sensors, stepper motors, or speakers, where a flat shape is essential for their operation.
Mounting: Their flat shape facilitates mounting, particularly when it's necessary to adhere the magnet to a surface.
Design Flexibility: The disc shape of the magnets allows designers with significant flexibility in placing them in constructions, which can be more difficult with magnets of other shapes.
Stability: In some applications, the flat base of a disc magnet may provide better stability, reducing the risk of sliding or rotating. It should be noted that the optimal shape of a magnet depends on the particular use and requirements. In certain cases, other shapes, like cylindrical or spherical, may be more suitable.

Advantages as well as disadvantages of neodymium magnets NdFeB.
Apart from immense strength, neodymium magnets have the following advantages:
- They do not lose strength over time. After approximately 10 years, their power decreases by only ~1% (theoretically),
- They are highly resistant to demagnetization by external magnetic sources,
- In other words, thanks to the shiny nickel, gold, or silver finish, the element gains an aesthetic appearance,
- They exhibit 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 form) even at temperatures of 230°C or higher...
- 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 amplifies their universality in usage.
- Wide application in the industry of new technologies – find application in computer drives, electric drive mechanisms, medical equipment and very highly developed apparatuses.
Disadvantages of neodymium magnets:
- They can break as they are extremely fragile 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 also increases its overall strength,
- Magnets lose their strength due to exposure to high temperatures. In most cases, when the temperature exceeds 80°C, these magnets experience permanent loss in strength (although it is worth noting that this is dependent on the form and size of the magnet). To avoid this problem, we offer special magnets marked with the [AH] symbol, which exhibit high temperature resistance. They can operate even at temperatures as high as 230°C or more,
- Magnets exposed to a humid environment can corrode. Therefore, when using them outdoors, we suggest using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
- The use of a cover or a magnetic holder is recommended due to the limited possibilities of manufacturing threads or complex shapes in the magnet
- Potential hazard arising from small pieces of magnets can be dangerous, if swallowed, which is crucial in the context of children's health. It's also worth noting that miniscule components of these magnets are able to hinder the diagnostic process when they are in the body.
Exercise Caution with Neodymium Magnets
Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.
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.
Keep neodymium magnets as far away as possible from GPS and smartphones.
Neodymium magnets generate intense magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
Magnets made of neodymium are extremely delicate, they easily fall apart and can crumble.
Neodymium magnets are characterized by considerable fragility. Neodymium magnetic are made of metal and coated with a shiny nickel, but they are not as durable 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.
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.
Magnets should not be treated as toys. Therefore, it is not recommended for children to have access to 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.
People with pacemakers are advised to avoid neodymium magnets.
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.
Neodymium magnets are the strongest magnets ever invented. Their power can surprise you.
Familiarize yourself with our information to correctly handle these magnets and avoid significant injuries to your body and prevent damage to the magnets.
Neodymium magnets can demagnetize 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.
Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.
Magnets will crack or crumble with careless joining to each other. Remember not to move them to each other or hold them firmly in hands at a distance less than 10 cm.
The magnet coating is made of nickel, so be cautious 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.
