Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Due to their power, flat magnets are commonly applied in devices that require strong holding power.
Typical temperature resistance of flat magnets is 80 °C, but with larger dimensions, this value rises.
Moreover, flat magnets often have special coatings applied to their surfaces, e.g. nickel, gold, or chrome, to increase their strength.
The magnet labeled MPL 30x10x5 / N38 and a magnetic force 6.84 kg which weighs only 11.25 grams, making it the ideal choice for projects needing a flat magnet.
Contact surface: Thanks to their flat shape, flat magnets guarantee a greater contact surface with adjacent parts, which is beneficial in applications requiring a stronger magnetic connection.
Technology applications: These magnets are often applied in various 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 another surface.
Design flexibility: The flat shape of the magnets allows designers greater flexibility in placing 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, minimizing the risk of shifting 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, such as 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 regularly used in magnetic technologies, e.g. motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the greatest strength of attraction, making them ideal for applications requiring strong magnetic fields. Moreover, 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. The Curie temperature is specific to each type of magnet, meaning that once this temperature is exceeded, the magnet stops being magnetic. Additionally, strong magnets can interfere with the operation of devices, such as navigational instruments, magnetic stripe cards or medical equipment, like pacemakers. Therefore, it is important to avoid placing magnets near such devices.

Advantages as well as disadvantages of neodymium magnets NdFeB.
Apart from immense power, neodymium magnets have the following advantages:
- They do not lose their strength (of the magnet). After approximately 10 years, their power decreases by only ~1% (theoretically),
- They are extremely resistant to demagnetization by external magnetic sources,
- In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
- They exhibit very 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 expands the range of their possible uses.
- Significant importance in advanced technologically fields – find application in computer drives, electric drive mechanisms, medical apparatus and other 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, it is suggested 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,
- 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 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,
- 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,
- Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
- Potential hazard arising from small pieces of magnets can be dangerous, when accidentally ingested, which is particularly important in the aspect of protecting young children. Furthermore, tiny parts of these magnets can complicate diagnosis in case of swallowing.
Exercise Caution with Neodymium Magnets
It is essential to maintain neodymium magnets out of reach from children.
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.
If you have a nickel allergy, avoid contact with neodymium magnets.
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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
Neodymium magnets are the strongest, most remarkable magnets on the planet, and the surprising force between them can shock you at first.
Familiarize yourself with our information to correctly handle these magnets and avoid significant injuries to your body and prevent disruption to the magnets.
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.
Keep neodymium magnets away from people with pacemakers.
Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.
Neodymium magnetic are fragile as well as can easily break and shatter.
Neodymium magnets are characterized by significant fragility. Neodymium magnetic 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.
Make sure not to bring neodymium magnets close to the 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 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.
Neodymium magnets can attract to each other, pinch the skin, and cause significant injuries.
If you have a finger between or on the path of attracting magnets, there may be a severe cut or even a fracture.
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.
So that know how powerful neodymium magnets are and why they are so dangerous, see the article - Dangerous strong neodymium magnets.
