Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Thanks to their mighty power, flat magnets are regularly applied in structures that require very strong attraction.
Most common temperature resistance of these magnets is 80 °C, but depending on the dimensions, this value can increase.
Moreover, flat magnets usually have special coatings applied to their surfaces, e.g. nickel, gold, or chrome, for enhancing their corrosion resistance.
The magnet named MPL 30x20x5 / N38 i.e. a magnetic force 9.67 kg which weighs only 22.50 grams, making it the excellent choice for applications requiring a flat shape.
Contact surface: Thanks to their flat shape, flat magnets ensure a greater contact surface with other components, which is beneficial in applications requiring a stronger magnetic connection.
Technology applications: These magnets are often applied in different devices, e.g. sensors, stepper motors, or speakers, where the flat shape is necessary for their operation.
Mounting: The flat form's flat shape simplifies mounting, particularly 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 placing them in structures, which is more difficult with magnets of more complex shapes.
Stability: In some applications, the flat base of the flat magnet can provide 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 application and requirements. In certain cases, other shapes, such as cylindrical or spherical, may be a better choice.
Magnets have two poles: north (N) and south (S), which attract each other when they are oppositely oriented. 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 greatest strength of attraction, making them indispensable for applications requiring strong magnetic fields. Moreover, the strength of a magnet depends on its size and the materials used.
It should be noted that extremely high temperatures, above the Curie point, cause a loss of magnetic properties in the magnet. Every magnetic material has its Curie point, 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, credit cards and even electronic devices sensitive to magnetic fields. For this reason, it is important to avoid placing magnets near such devices.

Advantages as well as disadvantages of neodymium magnets NdFeB.
Apart from immense strength, neodymium magnets have the following advantages:
- They do not lose their power (of the magnet). After approximately 10 years, their strength decreases by only ~1% (theoretically),
- They are highly resistant to demagnetization by external magnetic field,
- By applying a shiny coating of nickel, gold, or silver, the element gains an aesthetic appearance,
- They have very high magnetic induction on the surface of the magnet,
- Magnetic neodymium magnets are characterized by hugely high magnetic induction on the surface of the magnet and can operate (depending on the shape) even at temperatures of 230°C or higher...
- The ability for precise shaping and customization to specific needs – neodymium magnets can be produced in a wide range of shapes and sizes, which amplifies their universality in usage.
- Key role in modern technologies – are used in hard drives, electric drive mechanisms, medical apparatus or various technologically advanced devices.
Disadvantages of neodymium magnets:
- They are fragile when subjected to a strong impact. If the magnets are exposed to impacts, we recommend using magnets in a metal holder. The steel housing in the form of a holder protects the magnet from impacts, and at the same time increases its overall strength,
- High temperatures can reduce the power of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent reduction 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,
- 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 associated with microscopic parts of magnets pose a threat, in case of ingestion, which becomes significant in the aspect of protecting young children. It's also worth noting that tiny parts of these products have the potential to be problematic in medical diagnosis when they are in the body.
Be Cautious with Neodymium Magnets
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.
Avoid contact with neodymium magnets if you have a nickel 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.
Neodymium magnets can become demagnetized at high temperatures.
Although magnets are generally resilient, their ability to retain their magnetic strength can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.
You should keep neodymium magnets at a safe distance from the wallet, computer, and TV.
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. Avoid placing neodymium magnets in close proximity to electronic devices.
Magnets made of neodymium are particularly fragile, which leads to shattering.
In the event of a collision between two neodymium magnets, it can result in them getting chipped. Despite being made of metal and coated with a shiny nickel plating, they are not as hard as steel. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.
Keep neodymium magnets away from GPS and smartphones.
Neodymium magnets produce strong magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
Neodymium magnets should not be near 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. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.
Neodymium magnets should not be around youngest children.
Remember that neodymium magnets are not toys. Be cautious and make sure no child plays with them. They can be a significant choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing severe injuries, and even death.
Neodymium magnets are the most powerful magnets ever created, and their power can surprise you.
Read the information on our website on how to properly utilize neodymium magnets and avoid significant harm to your body and unintentional disruption to the magnets.
Neodymium magnets are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.
If joining of neodymium magnets is not under control, then they may crumble and crack. Remember not to approach them to each other or have them firmly in hands at a distance less than 10 cm.
