Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Thanks to their high strength, flat magnets are commonly applied in products that require strong holding power.
The standard temperature resistance of flat magnets is 80°C, but with larger dimensions, this value grows.
In addition, flat magnets usually have special coatings applied to their surfaces, such as nickel, gold, or chrome, for enhancing their corrosion resistance.
The magnet labeled MPL 40x15x6 / N38 and a lifting capacity of 11.61 kg weighing a mere 27.00 grams, making it the ideal choice for applications requiring a flat shape.
Contact surface: Thanks to their flat shape, flat magnets ensure a greater contact surface with adjacent parts, which can be beneficial in applications needing a stronger magnetic connection.
Technology applications: These are often applied in different devices, such as sensors, stepper motors, or speakers, where the thin and wide shape is necessary for their operation.
Mounting: The flat form's flat shape makes mounting, especially when there's a need to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets allows designers a lot of 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 offer better stability, reducing the risk of shifting or rotating. However, it's important to note that the optimal shape of the magnet depends on the given use and requirements. In some 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 different. Similar poles, e.g. two north poles, act repelling on each other.
Thanks to this principle of operation, magnets are regularly used in electrical devices, e.g. motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the greatest strength of attraction, making them perfect for applications requiring strong magnetic fields. Additionally, the strength of a magnet depends on its size and the material it is made of.
It’s worth noting 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. Interestingly, strong magnets can interfere with the operation of devices, such as navigational instruments, credit cards or electronic devices sensitive to magnetic fields. For this reason, it is important to avoid placing magnets near such devices.

Advantages and disadvantages of neodymium magnets NdFeB.
Apart from immense power, neodymium magnets have the following advantages:
- They do not lose strength over time - after 10 years, their strength decreases by only ~1% (theoretically),
- They are extremely resistant to demagnetization by external magnetic field,
- In other words, thanks to the glossy nickel, gold, or silver finish, the element gains an aesthetic appearance,
- They have very 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...
- The ability for precise shaping and customization to specific needs – neodymium magnets can be produced in a wide range of shapes and sizes, which enhances their versatility in applications.
- Wide application in advanced technologically fields – are used in hard drives, electric motors, medical devices 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 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 loss 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,
- They rust in a humid environment - during outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
- Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
- Health risk arising from small pieces of magnets can be dangerous, if swallowed, which is particularly important in the context of children's health. It's also worth noting that tiny parts of these magnets are able to complicate diagnosis after entering the body.
Handle with Care: Neodymium Magnets
Neodymium magnets can become demagnetized 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.
Never bring neodymium magnets close to a phone and GPS.
Magnetic fields can interfere with compasses and magnetometers used in aviation and maritime navigation, as well as internal compasses of smartphones and GPS devices. There are neodymium magnets in every smartphone, for example, in the microphone and speakers.
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.
Neodymium magnets jump and clash mutually within a distance of several to almost 10 cm from each other.
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.
Keep neodymium magnets away from the wallet, computer, and TV.
Strong magnetic fields emitted by neodymium magnets can damage 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. Avoid placing neodymium magnets in close proximity to electronic devices.
Neodymium magnets are the strongest, most remarkable magnets on earth, and the surprising force between them can surprise you at first.
Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional disruption to the magnets.
Neodymium magnets are not recommended for people with pacemakers.
Neodymium magnets produce strong magnetic fields that can interfere 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.
Magnets are not toys, children should not play with them.
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 highly fragile, they easily crack and can become damaged.
In the event of a collision between two neodymium magnets, it can result in them getting chipped. 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, small sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.
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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.
To raise awareness of why neodymium magnets are so dangerous, read the article titled How very dangerous are very strong neodymium magnets?.
