Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Thanks to their high strength, flat magnets are regularly applied in structures that require exceptional adhesion.
Most common temperature resistance of these magnets is 80 °C, but depending on the dimensions, this value can increase.
Moreover, flat magnets commonly have different coatings applied to their surfaces, e.g. nickel, gold, or chrome, for enhancing their strength.
The magnet with the designation MPL 20x10x1 / N38 and a magnetic force 1.12 kg with a weight of just 1.50 grams, making it the excellent 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 different devices, e.g. sensors, stepper motors, or speakers, where the thin and wide shape is important for their operation.
Mounting: Their flat shape makes mounting, especially when it is necessary to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets gives the possibility creators a lot of flexibility in arranging them in structures, which is more difficult with magnets of more complex shapes.
Stability: In some applications, the flat base of the flat magnet can provide better stability, minimizing the risk of sliding or rotating. It’s important to keep in mind that the optimal shape of the magnet depends on the specific project and requirements. In some cases, other shapes, such as cylindrical or spherical, may be more appropriate.
Magnets have two poles: north (N) and south (S), which attract each other when they are different. Poles of the same kind, such as two north poles, repel each other.
Thanks to this principle of operation, magnets are commonly used in magnetic technologies, 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. Additionally, 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. The Curie temperature is specific to each type of magnet, meaning that under such conditions, the magnet stops being magnetic. Additionally, 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 exercise caution when using magnets.

Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to immense strength, neodymium magnets have the following advantages:
- They do not lose strength over time - after about 10 years, their power decreases by only ~1% (theoretically),
- They protect against demagnetization caused by external magnetic field extremely 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,
- By using an appropriate combination of materials, they can achieve significant thermal resistance, allowing them to operate at temperatures up to 230°C and above...
- Thanks to the flexibility in shaping or the ability to adapt to specific requirements – neodymium magnets can be produced in a wide range of shapes and sizes, which expands the range of their possible uses.
- Significant importance in modern technologies – are used in computer drives, electric motors, medical devices and other advanced devices.
Disadvantages of neodymium magnets:
- They are fragile when subjected to a strong 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 at the same time increases its overall strength,
- Magnets lose their power due to exposure to high temperatures. In most cases, when the temperature exceeds 80°C, these magnets experience permanent loss in strength (although it is worth noting that this is dependent on the shape and size of the magnet). To avoid this problem, we offer special magnets marked with the [AH] symbol, which exhibit high temperature resistance. They can operate even at temperatures as high as 230°C or more,
- Magnets exposed to a humid environment can corrode. Therefore, when using them outdoors, we recommend 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
- Possible danger to health from tiny fragments of magnets pose a threat, in case of ingestion, which is crucial in the aspect of protecting young children. Furthermore, tiny parts of these magnets can be problematic in medical diagnosis in case of swallowing.
Exercise Caution with Neodymium Magnets
Keep neodymium magnets away from TV, wallet, and computer HDD.
The strong magnetic field generated by neodymium magnets can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also damage devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
Under no circumstances should neodymium magnets be brought close to GPS and smartphones.
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.
Neodymium magnets are the strongest, most remarkable magnets on earth, and the surprising force between them can surprise you at first.
Familiarize yourself with our information to correctly handle these magnets and avoid significant injuries to your body and prevent disruption to the magnets.
Magnets made of neodymium are known for their fragility, which can cause them to shatter.
Neodymium magnets are delicate as well as will break if allowed to collide with each other, even from a distance of a few centimeters. They are coated with a shiny nickel plating similar to steel, but they are not as hard. At the moment of connection between the magnets, tiny sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.
If you have a nickel allergy, avoid contact with neodymium magnets.
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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.
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.
Magnets should not be treated as toys. Therefore, it is not recommended for youngest children to have access to them.
Neodymium magnets are not toys. You cannot allow them to become toys for children. 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.
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.
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 can attract to each other, pinch the skin, and cause significant injuries.
Magnets will crack or crumble with careless joining to each other. Remember not to approach them to each other or hold them firmly in hands at a distance less than 10 cm.
