Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Due to their power, flat magnets are frequently used in devices that need exceptional adhesion.
Typical temperature resistance of these magnets is 80 °C, but depending on the dimensions, this value grows.
Moreover, flat magnets usually have special coatings applied to their surfaces, such as nickel, gold, or chrome, for enhancing their corrosion resistance.
The magnet with the designation MPL 50x20x5 / N38 i.e. a lifting capacity of 12.49 kg with a weight of only 37.50 grams, making it the perfect choice for applications requiring a flat shape.
Contact surface: Thanks to their flat shape, flat magnets guarantee a larger contact surface with other components, which can be beneficial in applications requiring a stronger magnetic connection.
Technology applications: These magnets are often utilized in various devices, e.g. sensors, stepper motors, or speakers, where the flat shape is necessary for their operation.
Mounting: Their flat shape makes it easier mounting, particularly when there's a need to attach the magnet to some surface.
Design flexibility: The flat shape of the magnets permits designers 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 offer better stability, minimizing the risk of shifting or rotating. However, it's important to note 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 main poles: north (N) and south (S), which attract each other when they are different. Similar poles, such as two north poles, repel 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 highest power of attraction, making them ideal for applications requiring powerful magnetic fields. Additionally, the strength of a magnet depends on its dimensions and the materials used.
It should be noted that extremely high temperatures, above the Curie point, cause a loss of magnetic properties in the magnet. 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 compasses, credit cards and even medical equipment, like pacemakers. 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 power decreases by only ~1% (theoretically),
- They are extremely resistant to demagnetization by external magnetic sources,
- By applying a shiny coating of nickel, gold, or silver, the element gains 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 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 a wide range of shapes and sizes, which expands the range of their possible uses.
- Significant importance in advanced technologically fields – are used in HDD drives, electric motors, medical equipment and very 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 simultaneously 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,
- Magnets exposed to a humid environment can corrode. Therefore, when using them outdoors, we suggest using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
- 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 associated with microscopic parts of magnets are risky, in case of ingestion, which is particularly important in the context of child safety. Furthermore, small elements of these devices have the potential to complicate diagnosis when they are in the body.
Exercise Caution with Neodymium Magnets
Neodymium magnets are the strongest magnets ever invented. Their strength 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.
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.
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 destroy devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
The magnet coating is made of nickel, so be cautious if you have an 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.
Neodymium magnetic are especially delicate, which leads to their breakage.
Magnets made of neodymium are extremely fragile, and by joining them in an uncontrolled manner, they will break. Magnets made of neodymium are made of metal and coated with a shiny nickel, but they are not as durable 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.
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.
Magnets may crack or alternatively crumble with uncontrolled joining to each other. You can't move them to each other. At a distance less than 10 cm you should have them extremely firmly.
Neodymium magnets should not be in the vicinity children.
Not all neodymium magnets are toys, so do not let children play with them. 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 GPS and smartphones.
Neodymium magnets are a source of strong magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
People with pacemakers are advised to avoid neodymium magnets.
Neodymium magnets produce strong magnetic fields that can interfere 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.
Neodymium magnets can demagnetize at high temperatures.
In certain circumstances, Neodymium magnets can lose their magnetism when subjected to high temperatures.
So you are aware of why neodymium magnets are so dangerous, see the article titled How very dangerous are very powerful neodymium magnets?.
