Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Thanks to their high strength, flat magnets are commonly used in structures that need very strong attraction.
Most common temperature resistance of flat magnets is 80°C, but depending on the dimensions, this value grows.
Additionally, flat magnets usually have special coatings applied to their surfaces, such as nickel, gold, or chrome, to improve their durability.
The magnet labeled MPL 30x15x2 / N38 i.e. a magnetic force 3.35 kg which weighs a mere 6.75 grams, making it the perfect choice for projects needing a flat magnet.
Contact surface: Thanks to their flat shape, flat magnets guarantee a larger contact surface with adjacent parts, which is beneficial in applications needing a stronger magnetic connection.
Technology applications: They are often utilized in various devices, e.g. sensors, stepper motors, or speakers, where the flat shape is important for their operation.
Mounting: Their flat shape makes it easier 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 a lot of flexibility in arranging them in structures, which can be more difficult with magnets of other shapes.
Stability: In some applications, the flat base of the flat magnet may offer better stability, reducing the risk of sliding or rotating. However, one should remember that the optimal shape of the magnet depends on the specific application and requirements. In certain cases, other shapes, such as cylindrical or spherical, are more appropriate.
Magnets have two poles: north (N) and south (S), which attract each other when they are different. Similar poles, e.g. two north poles, act repelling on each other.
Thanks to this principle of operation, magnets are commonly 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 strong magnetic fields. Moreover, the strength of a magnet depends on its dimensions and the materials used.
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 once this temperature is exceeded, the magnet stops being magnetic. Additionally, strong magnets can interfere with the operation of devices, such as compasses, credit cards or electronic devices sensitive to magnetic fields. Therefore, it is important to avoid placing magnets near such devices.

Advantages and disadvantages of neodymium magnets NdFeB.
Apart from immense power, neodymium magnets have the following advantages:
- They do not lose their strength (of the magnet). After about 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 exhibit very 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 many variants of shapes or sizes, which enhances their versatility in applications.
- Wide application in advanced technologically fields – find application in computer drives, electric motors, medical devices and other modern machines.
Disadvantages of neodymium magnets:
- They are prone to breaking as they are extremely fragile when subjected to a powerful impact. If the magnets are exposed to impacts, it is suggested using magnets in a metal holder. The steel housing in the form of a holder protects the magnet from impacts and also 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 shape 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,
- 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
- Possible danger associated with microscopic parts of magnets are risky, in case of ingestion, which is particularly important in the context of child safety. Furthermore, tiny parts of these products have the potential to complicate diagnosis when they are in the body.
Handle Neodymium Magnets with Caution
Magnets are not toys, youngest should not play with them.
Neodymium magnets are not toys. You cannot allow them to become toys for children. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.
Keep neodymium magnets away from TV, wallet, and computer HDD.
Strong fields generated by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other similar devices. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
Neodymium magnets can become demagnetized at high temperatures.
Under specific conditions, Neodymium magnets can lose their magnetism when subjected to high temperatures.
Keep neodymium magnets away from 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.
Avoid bringing neodymium magnets close to a phone or GPS.
Magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
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.
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 particularly delicate, resulting in their breakage.
Neodymium magnetic are extremely fragile, and by joining them in an uncontrolled manner, they will crumble. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.
Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.
Neodymium magnets will jump and also touch together within a radius of several to around 10 cm from each other.
Neodymium magnets are the most powerful magnets ever invented. Their strength can surprise you.
