Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Due to their power, flat magnets are regularly used in structures that require exceptional adhesion.
The standard temperature resistance of these magnets is 80°C, but depending on the dimensions, this value rises.
In addition, flat magnets often have special coatings applied to their surfaces, e.g. nickel, gold, or chrome, to improve their strength.
The magnet with the designation MPL 200x30x30 / N38 and a lifting capacity of 183.51 kg with a weight of a mere 1350.00 grams, making it the perfect choice for projects needing a flat magnet.
Contact surface: Thanks to their flat shape, flat magnets guarantee a larger contact surface with other components, which is beneficial in applications needing a stronger magnetic connection.
Technology applications: These magnets are often applied in many devices, such as sensors, stepper motors, or speakers, where the thin and wide shape is crucial for their operation.
Mounting: This form's flat shape simplifies mounting, particularly when it is necessary to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets allows creators a lot of 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, minimizing the risk of sliding or rotating. However, one should remember that the optimal shape of the magnet is dependent on the specific project and requirements. In some cases, other shapes, such as cylindrical or spherical, may be a better choice.
Magnets have two poles: north (N) and south (S), which interact with each other when they are different. Similar poles, such as 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 highest power of attraction, making them perfect for applications requiring strong magnetic fields. Additionally, the strength of a magnet depends on its dimensions and the material it is made of.
It should be noted 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. Interestingly, 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 avoid placing magnets near such devices.

Advantages and disadvantages of neodymium magnets NdFeB.
Apart from immense strength, 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 protect against demagnetization caused by external magnetic sources very well,
- Thanks to the shiny finish and nickel, gold, or silver coating, they have 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 high thermal resistance, allowing them to operate at temperatures up to 230°C and above...
- Due to the option of accurate forming or adaptation to individual needs – neodymium magnets can be produced in many variants of shapes and sizes, which enhances their versatility in applications.
- Key role in the industry of new technologies – find application in HDD drives, electric motors, medical equipment and other modern machines.
Disadvantages of neodymium magnets:
- They are prone to breaking as they are extremely fragile when subjected to a strong 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 loss 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,
- 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
- Possible danger arising from small pieces of magnets can be dangerous, in case of ingestion, which is crucial in the aspect of protecting young children. Furthermore, miniscule components of these magnets have the potential to complicate diagnosis in case of swallowing.
Be Cautious with Neodymium Magnets
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.
Under no circumstances should neodymium magnets be brought close to GPS and smartphones.
Intense magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
Magnets made of neodymium are particularly delicate, resulting in shattering.
Magnets made of neodymium are delicate 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, small sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.
Neodymium magnets are the most powerful, most remarkable magnets on earth, and the surprising force between them can shock you at first.
Familiarize yourself with our information to properly handle these magnets and avoid significant swellings to your body and prevent 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.
Neodymium magnets should not be in the vicinity youngest children.
Not all neodymium magnets are toys, so do not let children play with them. Small magnets pose a serious choking hazard or can attract to each other in the intestines. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.
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. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
The magnet is coated with nickel - be careful if you have an 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.
If the joining of neodymium magnets is not under control, then they may crumble and also crack. Remember not to approach them to each other or have them firmly in hands at a distance less than 10 cm.
Neodymium magnets can demagnetize 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.
