Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Due to their strength, flat magnets are regularly applied in devices that require exceptional adhesion.
The standard temperature resistance of these magnets is 80 °C, but with larger dimensions, this value grows.
Additionally, flat magnets often have special coatings applied to their surfaces, such as nickel, gold, or chrome, to increase their strength.
The magnet named MPL 40x40x15 / N38 and a lifting capacity of 47.38 kg with a weight of only 180.00 grams, making it the ideal choice for projects needing a flat magnet.
Contact surface: Due to their flat shape, flat magnets guarantee a larger contact surface with adjacent parts, which can be beneficial in applications requiring a stronger magnetic connection.
Technology applications: These magnets are often used in different devices, e.g. sensors, stepper motors, or speakers, where the thin and wide shape is necessary for their operation.
Mounting: The flat 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 permits creators greater flexibility in placing them in devices, which is more difficult with magnets of other shapes.
Stability: In some applications, the flat base of the flat magnet can offer better stability, minimizing the risk of shifting 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 a better choice.
Magnets have two poles: north (N) and south (S), which attract each other when they are different. Similar poles, e.g. two north poles, repel each other.
Thanks to this principle of operation, magnets are often used in magnetic technologies, 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 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, magnetic stripe cards or medical equipment, like pacemakers. For this reason, it is important to avoid placing magnets near such devices.

Advantages and disadvantages of neodymium magnets NdFeB.
Apart from immense strength, neodymium magnets have the following advantages:
- They do not lose power over time - after approximately 10 years, their power decreases by only ~1% (theoretically),
- They are exceptionally resistant to demagnetization caused by an external magnetic field,
- Thanks to the shiny finish and nickel, gold, or silver coating, they have an aesthetic appearance,
- They possess 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 or customization to specific needs – neodymium magnets can be produced in various forms and dimensions, which expands the range of their possible uses.
- Wide application in advanced technologically fields – are utilized in hard drives, electric motors, medical equipment and very highly developed apparatuses.
Disadvantages of neodymium magnets:
- They can break when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a metal holder. The steel housing in the form of a holder protects the magnet from impacts, and at the same time 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,
- Due to their susceptibility to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
- 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 becomes significant in the aspect of protecting young children. Furthermore, miniscule components of these products have the potential to be problematic in medical diagnosis in case of swallowing.
Safety Precautions
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 away from the wallet, computer, and TV.
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, etc. devices. They can also damage videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
Keep neodymium magnets as far away as possible 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.
Neodymium magnets can attract to each other, pinch the skin, and cause significant swellings.
If the joining of neodymium magnets is not under control, at that time they may crumble and crack. Remember not to approach them to each other or hold them firmly in hands at a distance less than 10 cm.
Neodymium magnets are over 10 times more powerful than ferrite magnets (the ones in speakers), and their power can surprise 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.
Neodymium magnets can become demagnetized at high temperatures.
Although magnets have demonstrated their effectiveness up to 80°C or 175°F, the temperature can vary depending on the type, shape, and intended use of the specific magnet.
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 happens because such devices have a function to deactivate them in a magnetic field.
Maintain neodymium magnets far from youngest children.
Neodymium magnets are not toys. Be cautious and make sure no child plays with them. In the case of swallowing multiple magnets simultaneously, they can attract to each other through the intestinal walls. In the worst case scenario, this can lead to death.
Neodymium magnetic are particularly delicate, resulting in their breakage.
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.
Avoid contact with neodymium magnets 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.
