Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Due to their power, flat magnets are commonly used in devices that need exceptional adhesion.
Typical temperature resistance of flat magnets is 80 °C, but with larger dimensions, this value can increase.
Additionally, flat magnets usually have special coatings applied to their surfaces, such as nickel, gold, or chrome, to increase their durability.
The magnet labeled MPL 3x3x3 / N38 i.e. a magnetic strength 0.71 kg weighing only 0.20 grams, making it the ideal 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 utilized in many devices, e.g. sensors, stepper motors, or speakers, where the flat shape is crucial for their operation.
Mounting: The flat form's flat shape simplifies mounting, particularly when there's a need to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets permits designers greater flexibility in arranging them in devices, which can be more difficult with magnets of more complex shapes.
Stability: In certain applications, the flat base of the flat magnet may offer better stability, reducing the risk of sliding or rotating. However, it's important to note that the optimal shape of the magnet is dependent on the specific project 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. Poles of the same kind, e.g. two north poles, repel each other.
Due to these properties, magnets are often used in electrical devices, 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. Additionally, the strength of a magnet depends on its dimensions and the materials used.
It should be noted 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. Additionally, strong magnets can interfere with the operation of devices, such as compasses, credit cards or electronic devices sensitive to magnetic fields. Therefore, it is important to avoid placing magnets near such devices.

Advantages and 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 strength decreases by only ~1% (theoretically),
- They are exceptionally resistant to demagnetization caused by an external magnetic field,
- In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires 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 high 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 various forms and dimensions, which enhances their versatility in applications.
- Wide application in modern technologies – are used in HDD drives, electric drive mechanisms, medical devices and very advanced devices.
Disadvantages of neodymium magnets:
- They are prone to breaking as they are extremely fragile when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a metal holder. The steel housing in the form of a holder protects the magnet from impacts and simultaneously increases its overall strength,
- High temperatures can reduce the strength of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent loss in strength (although it is dependent on the shape and size). To prevent this, we offer special magnets marked with the symbol [AH], which are highly resistant to high temperatures. They can operate even at temperatures up to 230°C, making them an ideal solution for applications requiring high-temperature operation,
- 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 or a magnetic holder is recommended due to the limited possibilities of manufacturing threads or complex shapes in the magnet
- Health risk to health from tiny fragments of magnets are risky, if swallowed, which is particularly important in the context of children's health. It's also worth noting that miniscule components of these products have the potential to complicate diagnosis after entering the body.
Notes with Neodymium Magnets
Dust and powder from neodymium magnets are flammable.
Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. Once crushed into fine powder or dust, this material becomes highly flammable.
Neodymium magnets can demagnetize 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.
The magnet coating contains nickel, so be cautious if you have a nickel 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.
Keep neodymium magnets as far away as possible from GPS and smartphones.
Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.
Neodymium magnetic are fragile and can easily break as well as shatter.
Neodymium magnetic are fragile and will shatter 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.
Magnets should not be treated as toys. Therefore, it is not recommended for children to have access to them.
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.
Neodymium magnets can attract to each other, pinch the skin, and cause significant injuries.
Neodymium magnets will bounce and also touch together within a radius of several to almost 10 cm from each other.
Neodymium magnets are not recommended for 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.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their power can shock you.
To handle magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.
Do not place neodymium magnets near a computer HDD, TV, and wallet.
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.
