Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Thanks to their high strength, flat magnets are commonly used in products that need very strong attraction.
Most common temperature resistance of these magnets is 80 °C, but depending on the dimensions, this value rises.
In addition, flat magnets often have special coatings applied to their surfaces, e.g. nickel, gold, or chrome, for enhancing their strength.
The magnet labeled MPL 40x18x10 / N38 and a magnetic strength 21.19 kg weighing only 54.00 grams, making it the ideal choice for applications requiring a flat shape.
Contact surface: Due to their flat shape, flat magnets ensure a larger contact surface with adjacent parts, which can be beneficial in applications needing a stronger magnetic connection.
Technology applications: These are often applied in various devices, such as sensors, stepper motors, or speakers, where the thin and wide shape is crucial for their operation.
Mounting: This form's flat shape simplifies mounting, particularly when it is required to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets allows designers greater flexibility in arranging them in structures, which is more difficult with magnets of other shapes.
Stability: In certain applications, the flat base of the flat magnet may provide better stability, reducing the risk of sliding or rotating. However, one should remember that the optimal shape of the magnet depends 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 different. Poles of the same kind, e.g. two north poles, act repelling on each other.
Due to these properties, magnets are regularly used in electrical devices, e.g. motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the highest power of attraction, making them ideal for applications requiring strong magnetic fields. Moreover, 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. Interestingly, strong magnets can interfere with the operation of devices, such as compasses, credit cards or electronic devices sensitive to magnetic fields. For this reason, it is important to exercise caution when using magnets.

Advantages and disadvantages of neodymium magnets NdFeB.
In addition to immense strength, neodymium magnets have the following advantages:
- They do not lose strength over time - after 10 years, their power decreases by only ~1% (theoretically),
- They are highly resistant to demagnetization by external magnetic sources,
- By applying a shiny coating of nickel, gold, or silver, the element gains an aesthetic appearance,
- They have very 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...
- Due to the option of accurate forming and adaptation to individual 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 the industry of new technologies – are utilized in computer drives, electric drive mechanisms, medical equipment or 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 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,
- 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 can be dangerous, in case of ingestion, which becomes significant in the context of children's health. Furthermore, miniscule components of these devices can be problematic in medical diagnosis when they are in the body.
Precautions
Keep neodymium magnets away from TV, wallet, and computer HDD.
Strong magnetic fields emitted by neodymium magnets can destroy magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
Neodymium magnets can demagnetize at high temperatures.
While Neodymium magnets can demagnetize at high temperatures, it's important to note that the extent of this effect can vary based on factors such as the magnet's material, shape, and intended application.
Do not give neodymium magnets to youngest children.
Neodymium magnets are not toys. You cannot allow them to become toys for children. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.
Neodymium magnets are the most powerful magnets ever invented. Their strength can shock you.
Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional damage to the magnets.
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.
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.
Neodymium magnetic are highly susceptible to damage, resulting in shattering.
Neodymium magnetic are extremely delicate, and by joining them in an uncontrolled manner, they will crack. Neodymium magnets are made of metal and coated with a shiny nickel, but they are not as durable 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.
Neodymium magnets should not be near people with pacemakers.
Neodymium magnets generate strong magnetic fields. As a result, they 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.
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 will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.
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, because a significant injury may occur. Magnets, depending on their size, can even cut off a finger or there can be a significant pressure or a fracture.
