Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Contact Surface: Due to their flat shape, disc magnets provide a significant contact surface with adjoining parts, which is beneficial in applications needing a stronger magnetic connection.
Applications in Technology: They are often employed in various devices, such as sensors, stepper motors, or speakers, where a thin and wide shape is essential for their operation.
Mounting: The flat form's flat shape makes mounting, especially when there's a need to adhere the magnet to a surface.
Design Flexibility: The disc shape of the magnets provides designers with greater flexibility in placing them in devices, which can sometimes be more difficult with magnets of other shapes.
Stability: In some applications, the flat base of a disc magnet can provide better stability, minimizing the risk of sliding or rotating. Nevertheless, one should bear in mind that the optimal shape of a magnet is dependent on the specific project and requirements. In certain cases, other shapes, like cylindrical or spherical, may be more suitable.

Advantages and disadvantages of neodymium magnets NdFeB.
Apart from immense strength, neodymium magnets have the following advantages:
- They do not lose their power (of the magnet). After approximately 10 years, their power decreases by only ~1% (theoretically),
- They are highly resistant to demagnetization by external magnetic sources,
- Thanks to the shiny finish and nickel, gold, or silver coating, they have an aesthetic appearance,
- They have very high magnetic induction on the surface of the magnet,
- By using an appropriate combination of materials, they can achieve significant thermal resistance, allowing them to operate 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 various forms and dimensions, which expands the range of their possible uses.
- Key role in the industry of new technologies – are used in hard drives, electric drive mechanisms, medical apparatus or very modern machines.
Disadvantages of neodymium magnets:
- They are prone to breaking as they are fragile when subjected to a strong 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 simultaneously increases its overall strength,
- High temperatures can reduce the power 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,
- Magnets exposed to a humid environment can corrode. Therefore, when using them outdoors, we recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
- Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
- Potential hazard associated with microscopic parts of magnets pose a threat, if swallowed, which is crucial in the aspect of protecting young children. Furthermore, small elements of these magnets are able to be problematic in medical diagnosis when they are in the body.
Precautions
Keep neodymium magnets as far away as possible from GPS and smartphones.
Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.
Neodymium magnetic are known for being fragile, which can cause them to shatter.
In the event of a collision between two neodymium magnets, it can result in them getting chipped. Despite being made of metal and 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.
Dust and powder from neodymium magnets are flammable.
Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.
If the joining of neodymium magnets is not under control, at that time they may crumble and also crack. You can't move them to each other. At a distance less than 10 cm you should have them extremely strongly.
Neodymium magnets are the strongest magnets ever invented. Their strength can shock you.
Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.
Neodymium magnets should not be in the vicinity children.
Neodymium magnets are not toys. You cannot allow them to become toys for children. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.
Keep neodymium magnets away from TV, wallet, and computer HDD.
Neodymium magnets produce 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. Do not forget to keep neodymium magnets away from these electronic devices.
Avoid contact with neodymium magnets if you have a nickel 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.
Neodymium magnets are not recommended for people with pacemakers.
Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.
Neodymium magnets can demagnetize at high temperatures.
Although magnets are generally resilient, their ability to retain their magnetic strength can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.
