Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Due to their strength, flat magnets are frequently applied in structures that require very strong attraction.
Typical temperature resistance of these magnets is 80 °C, but depending on the dimensions, this value rises.
In addition, flat magnets often have special coatings applied to their surfaces, such as nickel, gold, or chrome, to improve their durability.
The magnet named MPL 20x8x6 / N38 and a magnetic force 5.99 kg with a weight of just 7.20 grams, making it the ideal choice for projects needing a flat magnet.
Contact surface: Due to their flat shape, flat magnets guarantee a greater contact surface with other components, which can be beneficial in applications needing a stronger magnetic connection.
Technology applications: These magnets are often used in various devices, such as sensors, stepper motors, or speakers, where the flat shape is important for their operation.
Mounting: The flat form's flat shape makes mounting, especially when there's a need to attach the magnet to some surface.
Design flexibility: The flat shape of the magnets permits designers greater flexibility in placing them in devices, which can be more difficult with magnets of other shapes.
Stability: In some applications, the flat base of the flat magnet can provide better stability, minimizing the risk of sliding or rotating. It’s important to keep in mind that the optimal shape of the magnet is dependent on the given use and requirements. In certain cases, other shapes, such as cylindrical or spherical, may be a better choice.
Magnets have two poles: north (N) and south (S), which attract each other when they are oppositely oriented. Poles of the same kind, such as two north poles, repel each other.
Thanks to this principle of operation, magnets are regularly used in electrical devices, such as motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the highest power of attraction, making them perfect for applications requiring powerful magnetic fields. Moreover, the strength of a magnet depends on its size and the materials used.
It’s worth noting that high temperatures can weaken the magnet's effect. Every magnetic material has its Curie point, meaning that under such conditions, the magnet stops being magnetic. Additionally, strong magnets can interfere with the operation of devices, such as compasses, magnetic stripe cards and even electronic devices sensitive to magnetic fields. For this reason, it is important to avoid placing magnets near such devices.

Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to immense power, neodymium magnets have the following advantages:
- They do not lose strength over time. After 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 coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
- They possess 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...
- Due to the option of accurate forming and adaptation to individual needs – neodymium magnets can be produced in various forms and dimensions, which expands the range of their possible uses.
- Wide application in the industry of new technologies – are utilized in HDD drives, electric motors, medical apparatus or other advanced devices.
Disadvantages of neodymium magnets:
- They can break 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 shape 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,
- Due to their susceptibility to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
- 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 arising from small pieces of magnets pose a threat, in case of ingestion, which is crucial in the context of children's health. Furthermore, miniscule components of these devices have the potential to be problematic in medical diagnosis when they are in the body.
Safety Precautions
Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.
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. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.
Magnets made of neodymium are extremely fragile, resulting in breaking.
Neodymium magnets are characterized by significant fragility. Magnets made of neodymium are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of collision between the magnets, sharp metal fragments can be dispersed in different directions.
Neodymium magnets are the strongest, most remarkable magnets on earth, and the surprising force between them can shock you at first.
Familiarize yourself with our information to properly handle these magnets and avoid significant injuries to your body and prevent disruption to the magnets.
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.
If you have a nickel allergy, avoid contact with neodymium magnets.
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.
Magnets should not be treated as toys. Therefore, it is not recommended for youngest children to have access to them.
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 significant injuries, and even death.
Neodymium magnets can attract to each other, pinch the skin, and cause significant injuries.
If have a finger between or alternatively on the path of attracting magnets, there may be a large cut or a fracture.
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 is because many of these devices are equipped with a function that deactivates the device in a magnetic field.
Never bring neodymium magnets close to a phone and GPS.
Neodymium magnets generate strong magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
Neodymium magnets can become demagnetized 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.
So you are aware of why neodymium magnets are so dangerous, see the article titled How very dangerous are very powerful neodymium magnets?.
