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 other elements, which is beneficial in applications needing a stronger magnetic connection.
Applications in Technology: These magnets are often used in many devices, like sensors, stepper motors, or speakers, where a thin and wide shape is important for their operation.
Mounting: This form's flat shape makes mounting, particularly when you need to adhere the magnet to a surface.
Design Flexibility: The disc shape of the magnets provides designers with significant flexibility in arranging them in constructions, which can sometimes be more difficult with magnets of more complex shapes.
Stability: In certain applications, the flat base of a disc magnet can provide better stability, reducing the risk of shifting or rotating. It should be noted that the optimal shape of a magnet depends on the particular use and requirements. In some cases, other shapes, such as cylindrical or spherical, might be more suitable.

Advantages and disadvantages of neodymium magnets NdFeB.
Apart from immense power, 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 are exceptionally resistant to demagnetization caused by an 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...
- Thanks to the flexibility in shaping or the ability to adapt to specific requirements – neodymium magnets can be produced in a wide range of shapes and sizes, which amplifies their universality in usage.
- Wide application in the industry of new technologies – are used in hard drives, electric drive mechanisms, medical apparatus or other advanced devices.
Disadvantages of neodymium magnets:
- They can break 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 metal holder. The steel housing in the form of a holder protects the magnet from impacts and also increases its overall strength,
- They lose strength at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the form and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
- 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,
- Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
- Possible danger associated with microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the context of child safety. Furthermore, tiny parts of these devices can hinder the diagnostic process in case of swallowing.
Exercise Caution with Neodymium Magnets
Magnets made of neodymium are extremely fragile, leading to breaking.
Magnets made of neodymium are fragile 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 collision between the magnets, small sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.
Keep neodymium magnets away from 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.
Keep neodymium magnets away from people with pacemakers.
Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This is because many of these devices are equipped with a function that deactivates the device in a magnetic field.
Keep neodymium magnets away 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. They can also damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.
Neodymium magnets can attract to each other, pinch the skin, and cause significant injuries.
Magnets will crack or crumble with careless joining to each other. You can't approach them to each other. At a distance less than 10 cm you should have them extremely strongly.
Neodymium magnets can become demagnetized at high temperatures.
While Neodymium magnets can lose their magnetic properties 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.
Neodymium magnets are among the strongest magnets on Earth. The astonishing force they generate between each other can shock you.
Read the information on our website on how to properly utilize neodymium magnets and avoid significant harm to your body and unintentional damage to the magnets.
Dust and powder from neodymium magnets are highly flammable.
Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
The magnet coating contains nickel, so be cautious 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 should not be around 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.
