Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Due to their strength, flat magnets are frequently used in structures that require exceptional adhesion.
The standard temperature resistance of flat magnets is 80°C, but with larger dimensions, this value grows.
Additionally, flat magnets commonly have special coatings applied to their surfaces, such as nickel, gold, or chrome, for enhancing their strength.
The magnet with the designation MPL 5x4x1 / N38 and a magnetic force 0.35 kg which weighs only 0.15 grams, making it the excellent choice for projects needing a flat magnet.
Contact surface: Due to their flat shape, flat magnets guarantee a greater contact surface with adjacent parts, which is beneficial in applications needing a stronger magnetic connection.
Technology applications: These magnets are often applied in many devices, e.g. sensors, stepper motors, or speakers, where the flat shape is important for their operation.
Mounting: This form's flat shape simplifies mounting, particularly when it is required to attach the magnet to some surface.
Design flexibility: The flat shape of the magnets gives the possibility creators greater flexibility in arranging them in structures, which is more difficult with magnets of more complex shapes.
Stability: In some applications, the flat base of the flat magnet can provide better stability, minimizing the risk of shifting or rotating. It’s important to keep in mind that the optimal shape of the magnet depends on the specific application and requirements. In certain cases, other shapes, like cylindrical or spherical, may be more appropriate.
Magnets have two poles: north (N) and south (S), which attract each other when they are different. Similar poles, such as two north poles, act repelling on each other.
Due to these properties, magnets are commonly used in magnetic technologies, e.g. motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the greatest strength of attraction, making them ideal for applications requiring powerful magnetic fields. Moreover, the strength of a magnet depends on its size and the material it is made of.
It should be noted that high temperatures can weaken the magnet's effect. The Curie temperature is specific to each type of magnet, meaning that once this temperature is exceeded, the magnet stops being magnetic. Interestingly, strong magnets can interfere with the operation of devices, such as navigational instruments, magnetic stripe cards or electronic devices sensitive to magnetic fields. For this reason, it is important to exercise caution when using magnets.

Advantages as well as 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 strength decreases by only ~1% (theoretically),
- They protect against demagnetization caused by external magnetic sources very well,
- In other words, thanks to the glossy nickel, gold, or silver finish, the element gains an visually attractive appearance,
- They exhibit extremely high magnetic induction on the surface of the magnet,
- Magnetic neodymium magnets are characterized by hugely high magnetic induction on the surface of the magnet and can operate (depending on the shape) even at temperatures of 230°C or higher...
- The ability for precise shaping and customization to specific needs – neodymium magnets can be produced in a wide range of shapes and sizes, which enhances their versatility in applications.
- Key role in modern technologies – find application in HDD drives, electric drive mechanisms, medical equipment and other advanced devices.
Disadvantages of neodymium magnets:
- They can break as they are extremely fragile when subjected to a powerful 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 also 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,
- They rust in a humid environment. For outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
- 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 arising from small pieces of magnets can be dangerous, in case of ingestion, which is crucial in the context of child safety. Furthermore, miniscule components of these products can be problematic in medical diagnosis in case of swallowing.
Be Cautious with Neodymium Magnets
Neodymium magnets are highly susceptible to damage, resulting in shattering.
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.
Neodymium magnets can demagnetize at high temperatures.
Although magnets have shown to retain their effectiveness up to 80°C or 175°F, this temperature may vary depending on the type of material, shape, and intended use of the magnet.
Neodymium magnets are among the most powerful magnets on Earth. The astonishing force they generate between each other can surprise you.
Familiarize yourself with our information to properly handle these magnets and avoid significant swellings to your body and prevent disruption to the magnets.
It is important to maintain neodymium magnets out of reach from children.
Remember that 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.
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.
Keep neodymium magnets as far away as possible from GPS and smartphones.
Neodymium magnets produce intense magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.
Neodymium magnets generate 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 devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.
Neodymium magnets are not recommended for people with pacemakers.
Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.
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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.
Neodymium magnets are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.
Neodymium magnets jump and also clash mutually within a radius of several to around 10 cm from each other.
To raise awareness of why neodymium magnets are so dangerous, see the article titled How very dangerous are powerful neodymium magnets?.
