Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Thanks to their high strength, flat magnets are frequently applied in devices that need exceptional adhesion.
The standard temperature resistance of flat magnets is 80 °C, but depending on the dimensions, this value can increase.
Additionally, flat magnets often have special coatings applied to their surfaces, e.g. nickel, gold, or chrome, to improve their durability.
The magnet with the designation MPL 30x20x10 / N38 and a magnetic strength 17.29 kg which weighs only 45.00 grams, making it the ideal choice for applications requiring a flat shape.
Contact surface: Thanks to their flat shape, flat magnets guarantee a greater contact surface with other components, which is beneficial in applications needing a stronger magnetic connection.
Technology applications: These magnets are often used in many devices, such as sensors, stepper motors, or speakers, where the flat shape is crucial for their operation.
Mounting: Their flat shape simplifies mounting, particularly when there's a need to attach the magnet to some surface.
Design flexibility: The flat shape of the magnets allows designers a lot of flexibility in placing them in structures, which is 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 sliding 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 interact with each other when they are oppositely oriented. Poles of the same kind, e.g. two north poles, act repelling on each other.
Thanks to this principle of operation, magnets are regularly 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 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 once this temperature is exceeded, the magnet stops being magnetic. Additionally, strong magnets can interfere with the operation of devices, such as navigational instruments, credit cards and even medical equipment, like pacemakers. Therefore, it is important to avoid placing magnets near such devices.

Advantages as well as disadvantages of neodymium magnets NdFeB.
Apart from immense strength, neodymium magnets have the following advantages:
- They do not lose power over time - after about 10 years, their power decreases by only ~1% (theoretically),
- They are highly resistant to demagnetization by external magnetic sources,
- Thanks to the shiny finish and nickel, gold, or silver coating, they have an aesthetic appearance,
- They exhibit extremely 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 enhances their versatility in applications.
- Key role in advanced technologically fields – are used in hard drives, electric drive mechanisms, medical equipment or other advanced devices.
Disadvantages of neodymium magnets:
- They can break 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 strength due to exposure to high temperatures. In most cases, when the temperature exceeds 80°C, these magnets experience permanent reduction 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,
- They rust in a humid environment - during outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
- 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 context of children's health. Furthermore, small elements of these magnets are able to complicate diagnosis in case of swallowing.
Handle Neodymium Magnets with Caution
Neodymium magnets can become demagnetized at high temperatures.
Although magnets are generally resilient, their ability to retain their magnetic strength can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.
Keep neodymium magnets away from the wallet, computer, and TV.
Magnetic 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. Avoid placing neodymium magnets in close proximity to electronic devices.
The magnet is coated with nickel. Therefore, exercise caution 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.
Neodymium magnets should not be near people with pacemakers.
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.
Under no circumstances should neodymium magnets be brought close to GPS and smartphones.
Magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
Neodymium magnetic are particularly fragile, resulting in shattering.
Neodymium magnetic are fragile and will crack 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. 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.
Neodymium magnets are among the strongest magnets on Earth. The surprising force they generate between each other 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 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.
Magnets are not toys, youngest should not play with them.
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.
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.
If joining of neodymium magnets is not controlled, at that time they may crumble and also crack. Remember not to approach them to each other or have them firmly in hands at a distance less than 10 cm.
