Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Thanks to their mighty power, flat magnets are frequently applied in devices that require strong holding power.
Typical temperature resistance of flat magnets is 80°C, but with larger dimensions, this value can increase.
Additionally, flat magnets usually have special coatings applied to their surfaces, e.g. nickel, gold, or chrome, for enhancing their strength.
The magnet named MPL 40x10x5 / N38 i.e. a magnetic force 7.90 kg with a weight of a mere 15.00 grams, making it the perfect choice for applications requiring a flat shape.
Contact surface: Due to their flat shape, flat magnets guarantee a larger contact surface with adjacent parts, which is beneficial in applications requiring a stronger magnetic connection.
Technology applications: They are often applied in many devices, e.g. sensors, stepper motors, or speakers, where the flat shape is necessary for their operation.
Mounting: This form's flat shape makes it easier mounting, especially when it is required to attach the magnet to some surface.
Design flexibility: The flat shape of the magnets allows designers greater flexibility in placing them in structures, which can be more difficult with magnets of more complex shapes.
Stability: In some applications, the flat base of the flat magnet may provide better stability, minimizing the risk of sliding or rotating. However, it's important to note that the optimal shape of the magnet is dependent on the specific project and requirements. In some cases, other shapes, like cylindrical or spherical, may be a better choice.
Magnets have two poles: north (N) and south (S), which interact with each other when they are different. Similar poles, such as two north poles, repel each other.
Due to these properties, magnets are regularly used in magnetic technologies, such as motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the greatest strength of attraction, making them indispensable for applications requiring powerful magnetic fields. Moreover, the strength of a magnet depends on its size and the materials used.
It should be noted 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. Interestingly, strong magnets can interfere with the operation of devices, such as navigational instruments, credit cards or electronic devices sensitive to magnetic fields. Therefore, it is important to exercise caution when using magnets.

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 strength (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 exceptionally high magnetic induction on the surface of the magnet,
- Thanks to their high temperature resistance, they can operate (depending on the form) even at temperatures up to 230°C and above...
- The ability for precise shaping and customization to specific needs – neodymium magnets can be produced in a wide range of shapes and sizes, which expands the range of their possible uses.
- Wide application in the industry of new technologies – are used in computer drives, electric motors, medical equipment and other highly developed apparatuses.
Disadvantages of neodymium magnets:
- They are fragile 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,
- Magnets lose their strength due to exposure to high temperatures. In most cases, when the temperature exceeds 80°C, these magnets experience permanent reduction 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 recommend 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
- Health risk to health from tiny fragments of magnets pose a threat, when accidentally ingested, which becomes significant in the aspect of protecting young children. Additionally, miniscule components of these products have the potential to hinder the diagnostic process when they are in the body.
Be Cautious with Neodymium Magnets
Neodymium magnets can demagnetize at high temperatures.
Under specific conditions, Neodymium magnets can lose their magnetism when subjected to high temperatures.
People with pacemakers are advised to avoid neodymium magnets.
In the case of neodymium magnets, there is a strong magnetic field. As a result, it interferes with the operation of a heart pacemaker. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.
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.
Never bring neodymium magnets close to a phone and GPS.
Neodymium magnets generate intense magnetic fields that interfere 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 attract each other within a distance of several to about 10 cm from each other. Don't put your fingers in the path of magnet attraction, because a serious injury may occur. Depending on how massive the neodymium magnets are, they can lead to a cut or alternatively a fracture.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their strength can surprise you.
On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.
Neodymium magnets should not be around children.
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.
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, or other devices. They can also damage videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.
Neodymium magnetic are highly susceptible to damage, resulting in shattering.
Neodymium magnetic are delicate and will shatter 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. 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.
The magnet coating contains nickel, so be cautious if you have a nickel 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
In order for you to know how powerful neodymium magnets are and why they are so dangerous, see the article - Dangerous powerful neodymium magnets.
