Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Due to their power, flat magnets are frequently applied in products that require strong holding power.
Most common temperature resistance of these magnets is 80 °C, but with larger dimensions, this value rises.
Moreover, flat magnets often have special coatings applied to their surfaces, such as nickel, gold, or chrome, to increase their corrosion resistance.
The magnet labeled MPL 5x5x1 / N38 and a magnetic force 0.39 kg weighing just 0.19 grams, making it the ideal choice for projects needing a flat magnet.
Contact surface: Thanks to their flat shape, flat magnets ensure a larger contact surface with adjacent parts, which is beneficial in applications needing a stronger magnetic connection.
Technology applications: They are often utilized in different devices, such as sensors, stepper motors, or speakers, where the flat shape is necessary for their operation.
Mounting: Their flat shape makes it easier mounting, particularly when it is necessary to attach the magnet to some surface.
Design flexibility: The flat shape of the magnets permits designers greater flexibility in arranging them in structures, which is 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 shifting or rotating. It’s important to keep in mind 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 main poles: north (N) and south (S), which interact with each other when they are oppositely oriented. Poles of the same kind, such as two north poles, act repelling on each other.
Thanks to this principle of operation, magnets are often used in electrical devices, e.g. motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the highest power of attraction, making them perfect for applications requiring powerful magnetic fields. Additionally, the strength of a magnet depends on its size and the material it is made of.
It should be noted that extremely high temperatures, above the Curie point, cause a loss of magnetic properties in the magnet. The Curie temperature is specific to each type of magnet, meaning that under such conditions, the magnet stops being magnetic. Interestingly, strong magnets can interfere with the operation of devices, such as compasses, magnetic stripe 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 power 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 possess very high magnetic induction on the surface of the magnet,
- Thanks to their high temperature resistance, they can operate (depending on the form) even at temperatures up to 230°C and above...
- The ability for precise shaping and customization to specific needs – neodymium magnets can be produced in many variants of shapes and sizes, which amplifies their universality in usage.
- Significant importance in advanced technologically fields – find application in HDD drives, electric drive mechanisms, medical devices or very highly developed apparatuses.
Disadvantages of neodymium magnets:
- They are prone to breaking as they are fragile when subjected to a powerful 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 also 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,
- 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,
- Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
- Possible danger to health from tiny fragments of magnets are risky, if swallowed, which is crucial in the context of children's health. It's also worth noting that miniscule components of these products can complicate diagnosis in case of swallowing.
Handle Neodymium Magnets Carefully
Neodymium magnets can demagnetize at high temperatures.
While Neodymium magnets can lose their magnetic properties 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 place neodymium magnets near a computer HDD, TV, and wallet.
Neodymium magnets produce intense magnetic fields that 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. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.
The magnet coating is made of nickel, so be cautious 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.
Keep neodymium magnets away from 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. However, if the magnetic field does not affect the device, it can damage its components or deactivate the device when it is in a magnetic field.
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 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 properly handle these magnets and avoid significant swellings to your body and prevent damage to the magnets.
Neodymium magnets are delicate as well as can easily crack as well as get damaged.
Neodymium magnets are highly delicate, and by joining them in an uncontrolled manner, they will crumble. Magnets made of neodymium are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of collision between the magnets, small metal fragments can be dispersed in different directions.
Magnets should not be treated as toys. Therefore, it is not recommended for children to have access to them.
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.
Keep neodymium magnets as far away as possible from 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 magnets can attract to each other, pinch the skin, and cause significant injuries.
If have a finger between or alternatively on the path of attracting magnets, there may be a severe cut or a fracture.
