Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Due to their strength, flat magnets are frequently used in devices that require exceptional adhesion.
Most common temperature resistance of flat magnets is 80 °C, but with larger dimensions, this value rises.
Moreover, flat magnets commonly have different coatings applied to their surfaces, e.g. nickel, gold, or chrome, for enhancing their strength.
The magnet labeled MPL 30x10x8 / N38 and a lifting capacity of 10.94 kg with a weight of just 18.00 grams, making it the excellent choice for applications requiring a flat shape.
Contact surface: Thanks to their flat shape, flat magnets guarantee a larger contact surface with adjacent parts, which is beneficial in applications requiring a stronger magnetic connection.
Technology applications: These magnets are often used in different devices, e.g. sensors, stepper motors, or speakers, where the flat shape is necessary for their operation.
Mounting: This form's flat shape makes it easier mounting, particularly when it is required to attach the magnet to some surface.
Design flexibility: The flat shape of the magnets gives the possibility designers greater flexibility in arranging them in structures, which can be more difficult with magnets of other shapes.
Stability: In certain applications, the flat base of the flat magnet can provide better stability, minimizing the risk of sliding or rotating. It’s important to keep in mind that the optimal shape of the magnet is dependent on the specific application and requirements. In certain cases, other shapes, like cylindrical or spherical, may be a better choice.
Magnets have two main poles: north (N) and south (S), which attract each other when they are different. Similar poles, such as two north poles, repel 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 powerful 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. Every magnetic material has its Curie point, meaning that under such conditions, the magnet stops being magnetic. Additionally, strong magnets can interfere with the operation of devices, such as compasses, credit cards or medical equipment, like pacemakers. For this reason, it is important to exercise caution when using magnets.

Advantages and disadvantages of neodymium magnets NdFeB.
Apart from immense power, neodymium magnets have the following advantages:
- They do not lose their power (of the magnet). After about 10 years, their power decreases by only ~1% (theoretically),
- They protect against demagnetization caused by external magnetic sources extremely well,
- 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,
- Magnetic neodymium magnets are characterized by very high magnetic induction on the surface of the magnet and can operate (depending on the form) even at temperatures of 230°C or higher...
- The ability for precise shaping and customization to specific needs – neodymium magnets can be produced in various forms and dimensions, which enhances their versatility in applications.
- Key role in advanced technologically fields – are utilized in hard drives, electric motors, medical devices and various technologically advanced devices.
Disadvantages of neodymium magnets:
- They can break when subjected to a powerful 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,
- 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,
- Magnets exposed to a humid environment can corrode. Therefore, when using them outdoors, we recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
- 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
- Potential hazard associated with microscopic parts of magnets are risky, if swallowed, which is particularly important in the aspect of protecting young children. Additionally, tiny parts of these magnets can be problematic in medical diagnosis when they are in the body.
Safety Precautions
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.
Neodymium magnetic are particularly fragile, which leads to their breakage.
Magnets made of neodymium are fragile as well as 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 collision between the magnets, small sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.
Neodymium magnets can attract to each other, pinch the skin, and cause significant injuries.
Magnets attract each other within a distance of several to about 10 cm from each other. Don't put your fingers in the path of magnet attraction, as a major injury may occur. Magnets, depending on their size, can even cut off a finger or there can be a significant pressure or a fracture.
Do not bring neodymium magnets close to GPS and smartphones.
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.
Dust and powder from neodymium magnets are highly flammable.
Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
The magnet coating is made of nickel, so be cautious 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.
Do not place neodymium magnets near a computer HDD, TV, and wallet.
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. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
Do not give neodymium magnets to youngest children.
Remember that neodymium magnets are not toys. Do not allow children to play with them. Small magnets can pose a serious choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing significant injuries, and even death.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their power can surprise you.
Familiarize yourself with our information to correctly handle these magnets and avoid significant injuries to your body and prevent damage to the magnets.
Neodymium magnets are not recommended for 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.
