Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Due to their strength, flat magnets are commonly used in products that need very strong attraction.
Most common temperature resistance of flat magnets is 80°C, but with larger dimensions, this value can increase.
In addition, flat magnets commonly have special coatings applied to their surfaces, e.g. nickel, gold, or chrome, to increase their corrosion resistance.
The magnet named MPL 15x3x6 / N38 and a magnetic force 3.18 kg which weighs a mere 2.03 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: They are often applied in various devices, such as sensors, stepper motors, or speakers, where the flat shape is crucial for their operation.
Mounting: The flat form's flat shape simplifies mounting, especially when there's a need to attach the magnet to some surface.
Design flexibility: The flat shape of the magnets gives the possibility creators greater flexibility in arranging them in devices, which can be more difficult with magnets of other shapes.
Stability: In some applications, the flat base of the flat magnet may provide better stability, minimizing the risk of sliding or rotating. However, one should remember that the optimal shape of the magnet depends on the specific project and requirements. In certain 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, e.g. two north poles, act repelling on each other.
Thanks to this principle of operation, magnets are commonly used in magnetic technologies, e.g. motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the greatest strength of attraction, making them indispensable for applications requiring strong magnetic fields. Moreover, the strength of a magnet depends on its size and the material it is made of.
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 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 power, 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 are extremely resistant to demagnetization by external magnetic field,
- 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,
- Thanks to their high temperature resistance, they can operate (depending on the shape) 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 a wide range of shapes and sizes, which expands the range of their possible uses.
- Wide application in modern technologies – are utilized in computer drives, electric drive mechanisms, medical apparatus and very highly developed apparatuses.
Disadvantages of neodymium magnets:
- 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 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 reduction in strength (although it is worth noting that this is dependent on the form 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 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
- Possible danger to health from tiny fragments of magnets are risky, in case of ingestion, which is particularly important in the context of child safety. Additionally, miniscule components of these magnets are able to complicate diagnosis after entering the body.
Be Cautious with Neodymium Magnets
Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.
Magnets will crack or alternatively crumble with careless connecting to each other. You can't approach them to each other. At a distance less than 10 cm you should hold them very strongly.
Dust and powder from neodymium magnets are flammable.
Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.
The magnet is coated with nickel - be careful if you have an 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.
Magnets are not toys, children should not play with them.
Remember that 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 magnets are over 10 times more powerful than ferrite magnets (the ones in speakers), and their strength 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.
Never bring neodymium magnets close to a phone and GPS.
Neodymium magnets produce intense magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
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.
Do not place neodymium magnets near a computer HDD, TV, and wallet.
Strong 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.
Neodymium magnetic are highly delicate, they easily crack as well as can crumble.
Neodymium magnets are characterized by significant fragility. 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.
People with pacemakers are advised to avoid neodymium magnets.
Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This is because many of these devices are equipped with a function that deactivates the device in a magnetic field.
