Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Contact Surface: Due to their flat shape, disc magnets provide a larger contact surface with adjoining parts, which can be beneficial in applications requiring a stronger magnetic connection.
Applications in Technology: They are often used in different devices, like sensors, stepper motors, or speakers, where a flat shape is essential for their operation.
Mounting: This form's flat shape facilitates mounting, particularly when it's necessary to adhere the magnet to another surface.
Design Flexibility: The disc shape of the magnets provides designers with greater flexibility in arranging them in constructions, which can sometimes be more difficult with magnets of other shapes.
Stability: In certain applications, the flat base of a disc magnet can offer better stability, reducing the risk of shifting or rotating. Nevertheless, one should bear in mind that the optimal shape of a magnet is dependent on the specific application and requirements. In certain cases, other shapes, like cylindrical or spherical, may be a better choice.

Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to 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 extremely resistant to demagnetization by external magnetic field,
- Thanks to the shiny finish and nickel, gold, or silver coating, they have an aesthetic appearance,
- They exhibit extremely 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 various forms and dimensions, which enhances their versatility in applications.
- Significant importance in modern technologies – are used in HDD drives, electric motors, medical apparatus or various technologically advanced devices.
Disadvantages of neodymium magnets:
- They are prone to breaking as they are extremely fragile when subjected to a strong impact. If the magnets are exposed to impacts, it is suggested 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,
- High temperatures can reduce the strength of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent loss 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,
- 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 - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
- Potential hazard associated with microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the context of child safety. Furthermore, small elements of these devices can be problematic in medical diagnosis when they are in the body.
Precautions
Dust and powder from neodymium magnets are highly flammable.
Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.
Keep neodymium magnets away from the wallet, computer, and TV.
Strong magnetic fields emitted by neodymium magnets can destroy magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
Neodymium Magnets can attract to each other, pinch the skin, and cause significant swellings.
Magnets attract each other within a distance of several to about 10 cm from each other. Remember not to put fingers between magnets or in their path when attract. Depending on how huge the neodymium magnets are, they can lead to a cut or a fracture.
The magnet coating is made of nickel, so be cautious 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.
Neodymium magnets are fragile as well as can easily crack as well as get damaged.
In the event of a collision between two neodymium magnets, it can result in them getting chipped. 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 the most powerful magnets ever invented. Their strength can surprise you.
Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional disruption to the magnets.
Neodymium magnets can demagnetize at high temperatures.
Despite the fact that magnets have been found to maintain their efficacy up to temperatures of 80°C or 175°F, it's essential to consider that this threshold may fluctuate depending on the magnet's type, configuration, and intended usage.
Neodymium magnets are not recommended for people with pacemakers.
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.
Keep neodymium magnets far from youngest children.
Neodymium magnets are not toys. Be cautious and make sure no child plays with them. Small magnets can pose a serious choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing severe injuries, and even death.
Do not bring neodymium magnets close to GPS and smartphones.
Intense magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
