Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Due to their power, flat magnets are frequently used in devices that need exceptional adhesion.
The standard temperature resistance of these magnets is 80°C, but depending on the dimensions, this value rises.
Additionally, flat magnets commonly have different coatings applied to their surfaces, e.g. nickel, gold, or chrome, to improve their corrosion resistance.
The magnet named MPL 50x30x4 / N38 i.e. a magnetic strength 0.00 kg which weighs only 45.00 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 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 thin and wide shape is necessary for their operation.
Mounting: This 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 permits designers a lot of flexibility in placing them in devices, 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 sliding or rotating. It’s important to keep in mind that the optimal shape of the magnet depends on the specific application and requirements. In some cases, other shapes, such as cylindrical or spherical, are 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, e.g. two north poles, act repelling on each other.
Due to these properties, magnets are often used in magnetic technologies, such as motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the highest power of attraction, making them indispensable for applications requiring powerful magnetic fields. Moreover, the strength of a magnet depends on its dimensions 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. Additionally, strong magnets can interfere with the operation of devices, such as compasses, magnetic stripe cards or medical equipment, like pacemakers. Therefore, it is important to exercise caution when using magnets.

Advantages and disadvantages of neodymium magnets NdFeB.
In addition to immense power, 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 protect against demagnetization caused by external magnetic sources very well,
- In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
- They have very high magnetic induction on the surface of the magnet,
- Magnetic neodymium magnets are characterized by very high magnetic induction on the surface of the magnet and can operate (depending on the shape) even at temperatures of 230°C or higher...
- Thanks to the flexibility in shaping and the ability to adapt to specific requirements – neodymium magnets can be produced in various forms and dimensions, which amplifies their universality in usage.
- Key role in advanced technologically fields – are utilized in hard drives, electric motors, medical equipment or other highly developed apparatuses.
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 steel housing. The steel housing in the form of a holder protects the magnet from impacts and also 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 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 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
- Possible danger associated with microscopic parts of magnets pose a threat, if swallowed, which is crucial in the aspect of protecting young children. Additionally, miniscule components of these devices are able to complicate diagnosis in case of swallowing.
Caution with 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.
You should maintain neodymium magnets at a safe distance 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. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
Neodymium magnetic are highly susceptible to damage, resulting in breaking.
Neodymium magnets 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 surface, but they are not as hard as steel. At the moment of connection between the magnets, small metal fragments can be dispersed in different directions.
People with pacemakers are advised to avoid neodymium magnets.
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.
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 as far away as possible from 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.
Magnets are not toys, children should not play with them.
Not all neodymium magnets are toys, so do not let children play with them. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.
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.
If joining of neodymium magnets is not under control, at that time they may crumble and also crack. You can't move them to each other. At a distance less than 10 cm you should have them very firmly.
Dust and powder from neodymium magnets are flammable.
Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.
Neodymium magnets are the strongest magnets ever created, 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.
