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 needing a stronger magnetic connection.
Applications in Technology: These magnets are often used in many devices, like sensors, stepper motors, or speakers, where a flat shape is essential for their operation.
Mounting: This form's flat shape makes mounting, especially when you need to adhere the magnet to another surface.
Design Flexibility: The disc shape of the magnets provides designers with significant flexibility in placing them in constructions, which can be more difficult with magnets of more complex shapes.
Stability: In some applications, the flat base of a disc magnet can offer better stability, reducing the risk of shifting or rotating. It should be noted that the optimal shape of a magnet is dependent on the specific application and requirements. In certain cases, other shapes, such as cylindrical or spherical, might be a better choice.

Advantages and disadvantages of neodymium magnets NdFeB.
In addition to immense strength, neodymium magnets have the following advantages:
- They do not lose strength over time - after about 10 years, their strength decreases by only ~1% (theoretically),
- They are highly resistant to demagnetization by external magnetic field,
- In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
- They exhibit very 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 or the ability to adapt to specific requirements – neodymium magnets can be produced in many variants of shapes or sizes, which enhances their versatility in applications.
- Significant importance in the industry of new technologies – are utilized in hard drives, electric drive mechanisms, medical equipment and very modern machines.
Disadvantages of neodymium magnets:
- They can break as they are fragile 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 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 pose a threat, if swallowed, which is crucial in the aspect of protecting young children. Additionally, tiny parts of these products can hinder the diagnostic process after entering the body.
Be Cautious with Neodymium Magnets
Magnets made of neodymium are highly delicate, they easily break as well as can become damaged.
Neodymium magnets are characterized by considerable fragility. Neodymium magnets are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of connection between the magnets, small metal fragments can be dispersed in different directions.
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.
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.
Neodymium magnets can demagnetize at high temperatures.
While Neodymium magnets can lose their magnetic properties at high temperatures, it's important to note that the extent of this effect can vary based on factors such as the magnet's material, shape, and intended application.
It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.
Magnets may crack or alternatively crumble with uncontrolled joining to each other. You can't move them to each other. At a distance less than 10 cm you should hold them extremely firmly.
Magnets are not toys, children should not play with them.
Not all neodymium magnets are toys, so do not let children play with them. Small magnets pose a serious choking hazard or can attract to each other in the intestines. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.
The magnet is coated with nickel - be careful 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
Keep neodymium magnets away from the wallet, computer, and TV.
Neodymium magnets produce intense magnetic fields that can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also damage devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.
Neodymium magnets should not be near people with pacemakers.
In the case of neodymium magnets, there is a strong magnetic field. As a result, it interferes 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.
Neodymium magnets are the strongest, most remarkable magnets on earth, and the surprising force between them can shock you at first.
To handle magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.
