Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Contact Surface: Thanks to their flat shape, disc magnets provide a larger contact surface with adjoining parts, which is beneficial in applications requiring a stronger magnetic connection.
Applications in Technology: They are often employed in various devices, like sensors, stepper motors, or speakers, where a thin and wide shape is essential for their operation.
Mounting: The flat form's flat shape makes mounting, particularly when it's necessary to adhere the magnet to another surface.
Design Flexibility: The disc shape of the magnets provides designers with greater flexibility in arranging them in devices, which can sometimes be more difficult with magnets of more complex shapes.
Stability: In some applications, the flat base of a disc magnet can offer better stability, minimizing the risk of sliding or rotating. It should be noted that the optimal shape of a magnet depends on the specific project and requirements. In certain cases, other shapes, like cylindrical or spherical, may be a better choice.

Advantages as well as disadvantages of neodymium magnets NdFeB.
Apart from immense strength, neodymium magnets have the following advantages:
- They do not lose power over time - after about 10 years, their strength decreases by only ~1% (theoretically),
- They are highly resistant to demagnetization by external magnetic field,
- Thanks to the shiny finish and nickel, gold, or silver coating, they have 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...
- Due to the option of accurate forming and adaptation to individual needs – neodymium magnets can be produced in a wide range of shapes and sizes, which expands the range of their possible uses.
- Significant importance in the industry of new technologies – are utilized in HDD drives, electric drive mechanisms, medical apparatus or very modern machines.
Disadvantages of neodymium magnets:
- They are prone to breaking as they are 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 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,
- 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
- Possible danger associated with microscopic parts of magnets are risky, if swallowed, which becomes significant in the context of child safety. It's also worth noting that miniscule components of these products have the potential to hinder the diagnostic process in case of swallowing.
Precautions
Avoid bringing neodymium magnets close to a phone or GPS.
Strong fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
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.
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.
Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.
The strong magnetic field generated by neodymium magnets can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also damage videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.
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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
Neodymium magnets can attract to each other, pinch the skin, and cause significant injuries.
Magnets attract each other within a distance of several to around 10 cm from each other. Don't put your fingers in the path of magnet attraction, because a serious injury may occur. Depending on how huge the neodymium magnets are, they can lead to a cut or alternatively a fracture.
Magnets made of neodymium are extremely fragile, leading to their cracking.
Magnets made of neodymium are delicate as well as will break 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, tiny sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.
People with pacemakers are advised to avoid neodymium magnets.
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.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times stronger, and their power can shock you.

Keep neodymium magnets far from youngest children.
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 significant injuries, and even death.
So that know how strong neodymium magnets are and why they are so dangerous, read the article - Dangerous powerful neodymium magnets.
