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 other elements, which is beneficial in applications needing a stronger magnetic connection.
Applications in Technology: The magnets are often employed in different devices, such as sensors, stepper motors, or speakers, where a thin and wide shape is crucial for their operation.
Mounting: Their flat shape facilitates mounting, particularly when you need to adhere the magnet to a surface.
Design Flexibility: The disc shape of the magnets provides designers with greater flexibility in arranging 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 may offer better stability, minimizing the risk of sliding or rotating. It should be noted that the optimal shape of a magnet depends on the specific project and requirements. In some cases, other shapes, such as cylindrical or spherical, may be a better choice.

Advantages as well as 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 sources,
- Thanks to the shiny finish and nickel, gold, or silver coating, they have an aesthetic appearance,
- They exhibit 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 and the ability to adapt to specific requirements – neodymium magnets can be produced in a wide range of shapes and sizes, which enhances their versatility in applications.
- Key role in modern technologies – are utilized in computer drives, electric drive mechanisms, medical devices and very modern machines.
Disadvantages of neodymium magnets:
- They can break when subjected to a strong impact. If the magnets are exposed to impacts, we recommend using magnets in a protective case. 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 power 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,
- Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
- Potential hazard arising from small pieces of magnets are risky, in case of ingestion, which is crucial in the context of children's health. It's also worth noting that small elements of these magnets have the potential to hinder the diagnostic process when they are in the body.
Exercise Caution with Neodymium Magnets
Neodymium magnets can demagnetize at high temperatures.
In certain circumstances, Neodymium magnets can lose their magnetism when subjected to high temperatures.
Never bring neodymium magnets close to a phone and GPS.
Neodymium magnets are a source of intense magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
Neodymium magnets can attract to each other due to their immense internal force, causing the skin and other body parts to get pinched and resulting in significant swellings.
Magnets will jump and touch together within a radius of several to almost 10 cm from each other.
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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
Neodymium magnets should not be in the vicinity children.
Neodymium magnets are not toys. Do not allow children to play 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.
Keep neodymium magnets away from TV, wallet, and computer HDD.
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, 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 highly flammable.
Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.
Neodymium magnetic are noted for being fragile, which can cause them to shatter.
Neodymium magnets are delicate and will break if allowed to collide with each other, even from a distance of a few centimeters. They are coated with a shiny nickel plating similar to steel, but they are not as hard. At the moment of collision between the magnets, tiny sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.
Neodymium magnets are among the strongest magnets on Earth. The astonishing force they generate between each other can surprise you.

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.
