Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Due to their strength, flat magnets are commonly applied in structures that require very strong attraction.
The standard temperature resistance of these magnets is 80°C, but with larger dimensions, this value can increase.
In addition, flat magnets commonly have different coatings applied to their surfaces, such as nickel, gold, or chrome, for enhancing their corrosion resistance.
The magnet with the designation MPL 10x10x4 / N38 and a magnetic strength 3.16 kg which weighs just 3.00 grams, making it the excellent 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 is beneficial in applications requiring a stronger magnetic connection.
Technology applications: These are often applied in various devices, e.g. sensors, stepper motors, or speakers, where the flat shape is necessary for their operation.
Mounting: The flat 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 designers a lot of flexibility in placing them in devices, which can be more difficult with magnets of more complex shapes.
Stability: In some applications, the flat base of the flat magnet may provide better stability, minimizing the risk of shifting or rotating. However, one should remember that the optimal shape of the magnet depends on the given use and requirements. In some cases, other shapes, like cylindrical or spherical, are a better choice.
Magnets have two poles: north (N) and south (S), which attract each other when they are different. Similar poles, such as two north poles, repel each other.
Thanks to this principle of operation, magnets are often used in electrical devices, such as motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the greatest strength of attraction, making them ideal for applications requiring strong magnetic fields. Moreover, the strength of a magnet depends on its size and the materials used.
It’s worth noting 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 compasses, magnetic stripe cards or medical equipment, like pacemakers. For this reason, it is important to avoid placing magnets near such devices.

Shopping tips
Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to 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,
- In other words, thanks to the shiny nickel, gold, or silver finish, the element gains an aesthetic appearance,
- They exhibit very 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...
- The ability for precise shaping or customization to specific needs – neodymium magnets can be produced in a wide range of shapes and sizes, which expands the range of their possible uses.
- Wide application in modern technologies – are used in computer drives, electric drive mechanisms, medical equipment or various technologically advanced devices.
Disadvantages of neodymium magnets:
- They can break as they are fragile when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a protective case. 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 form and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
- Due to their susceptibility to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
- 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
- Health risk associated with microscopic parts of magnets pose a threat, if swallowed, which is crucial in the context of children's health. Additionally, miniscule components of these magnets can be problematic in medical diagnosis in case of swallowing.
Safety Precautions
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.
Under no circumstances should neodymium magnets be placed 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 videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.
Neodymium magnets are the most powerful magnets ever created, 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.
It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.
Magnets attract each other within a distance of several to about 10 cm from each other. Don't put your fingers in the path of magnet attraction, as a serious injury may occur. Depending on how large the neodymium magnets are, they can lead to a cut or alternatively a fracture.
Magnets made of neodymium are extremely delicate, they easily break and can crumble.
Neodymium magnets 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.
Dust and powder from neodymium magnets are highly 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.
Under no circumstances should neodymium magnets be brought close to GPS and smartphones.
Strong fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
Keep neodymium magnets far from youngest children.
Remember that neodymium magnets are not toys. Do not allow children to play 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.
Keep neodymium magnets away from 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.
So that know how strong neodymium magnets are and why they are so dangerous, read the article - Dangerous very powerful neodymium magnets.
