Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Due to their power, flat magnets are regularly used in devices that require strong holding power.
Most common temperature resistance of these magnets is 80°C, but depending on the dimensions, this value grows.
Moreover, flat magnets commonly have special coatings applied to their surfaces, e.g. nickel, gold, or chrome, for enhancing their durability.
The magnet labeled MPL 30x10x8 / N38 and a lifting capacity of 10.94 kg which weighs a mere 18.00 grams, making it the perfect choice for projects needing a flat magnet.
Contact surface: Due to their flat shape, flat magnets ensure a greater contact surface with other components, which can be beneficial in applications needing a stronger magnetic connection.
Technology applications: These are often utilized in various devices, such as sensors, stepper motors, or speakers, where the thin and wide shape is important for their operation.
Mounting: This 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 gives the possibility creators a lot of flexibility in placing them in structures, which can be more difficult with magnets of other shapes.
Stability: In certain applications, the flat base of the flat magnet may provide better stability, reducing the risk of sliding or rotating. However, it's important to note that the optimal shape of the magnet is dependent on the given use 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 interact with each other when they are oppositely oriented. Poles of the same kind, e.g. two north poles, repel each other.
Due to these properties, magnets are often used in magnetic technologies, e.g. motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the highest power of attraction, making them perfect for applications requiring strong magnetic fields. Moreover, the strength of a magnet depends on its dimensions and the material it is made of.
It’s worth noting that extremely high temperatures, above the Curie point, cause a loss of magnetic properties in the magnet. The Curie temperature is specific to each type of magnet, meaning that under such conditions, the magnet stops being magnetic. Interestingly, strong magnets can interfere with the operation of devices, such as compasses, credit cards and even electronic devices sensitive to magnetic fields. Therefore, it is important to avoid placing magnets near such devices.

Advantages as well as disadvantages of neodymium magnets NdFeB.
Apart from immense power, 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 protect against demagnetization caused by external magnetic field very well,
- In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
- They have exceptionally 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 form) even at temperatures of 230°C or higher...
- Due to the option of accurate forming and adaptation to individual needs – neodymium magnets can be produced in a wide range of shapes and sizes, which amplifies their universality in usage.
- Wide application in the industry of new technologies – are utilized in computer drives, electric motors, medical apparatus or very advanced devices.
Disadvantages of neodymium magnets:
- They are prone to breaking as they are 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 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,
- They rust in a humid environment - during 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 associated with microscopic parts of magnets pose a threat, when accidentally ingested, which is particularly important in the context of children's health. It's also worth noting that tiny parts of these products are able to be problematic in medical diagnosis after entering the body.
Handle Neodymium Magnets with Caution
Never bring neodymium magnets close to a phone and GPS.
Magnetic fields can interfere with compasses and magnetometers used in aviation and maritime navigation, as well as internal compasses of smartphones and GPS devices. There are neodymium magnets in every smartphone, for example, in the microphone and speakers.
It is important to keep neodymium magnets away from youngest children.
Not all neodymium magnets are toys, so do not let children play with them. In the case of small magnets, they can be swallowed and cause choking. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.
Do not place neodymium magnets near a computer HDD, TV, and wallet.
The strong magnetic field generated by neodymium magnets can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also damage videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
Magnets made of neodymium are delicate as well as can easily crack as well as shatter.
Magnets made of neodymium are highly delicate, and by joining them in an uncontrolled manner, they will break. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. At the moment of collision between the magnets, sharp metal fragments can be dispersed in different directions.
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 injuries.
If you have a finger between or on the path of attracting magnets, there may be a serious cut or a fracture.
Neodymium magnets can become demagnetized at high temperatures.
In certain circumstances, Neodymium magnets can lose their magnetism when subjected to high temperatures.
Dust and powder from neodymium magnets are flammable.
Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
Neodymium magnets are over 10 times more powerful than ferrite magnets (the ones in speakers), and their power 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.
The magnet coating contains nickel, so be cautious 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
Neodymium magnets are not recommended for people with pacemakers.
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.
So that know how strong neodymium magnets are and why they are so dangerous, see the article - Dangerous strong neodymium magnets.
