Neodymium disc magnets present a range of advantages in relation to other magnet shapes, which cause them to be the ideal choice for numerous projects:
Contact Surface: Due to their flat shape, disc magnets guarantee a significant contact surface with other elements, which is beneficial in applications needing a stronger magnetic connection.
Applications in Technology: The magnets are often used in various devices, such as sensors, stepper motors, or speakers, where a flat shape is essential for their operation.
Mounting: Their flat shape makes mounting, particularly when there's a need to adhere the magnet to another surface.
Design Flexibility: The disc shape of the magnets provides designers with greater flexibility in arranging them in constructions, 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. However, it's important to remember that the optimal shape of a magnet depends on the particular use and requirements. In certain cases, other shapes, such as cylindrical or spherical, might be more suitable.

Advantages as well as 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 approximately 10 years, their strength decreases by only ~1% (theoretically),
  • They protect against demagnetization caused by external magnetic field very well,
  • In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
  • They have exceptionally high magnetic induction on the surface of the magnet,
  • Thanks to their high temperature resistance, they can operate (depending on the shape) even 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 expands the range of their possible uses.
  • Wide application in advanced technologically fields – are used in HDD drives, electric drive mechanisms, medical devices and very modern machines.

Disadvantages of neodymium magnets:

  • They are prone to breaking as they are fragile when subjected to a strong 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 simultaneously increases its overall strength,
  • They lose power at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the shape and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
  • They rust in a humid environment. For outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
  • The use of a cover - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
  • 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 devices have the potential to be problematic in medical diagnosis in case of swallowing.

Exercise Caution with Neodymium Magnets

  Magnets are not toys, children should not play with them.

Remember that neodymium magnets are not toys. Do not allow children to play with them. In the case of swallowing multiple magnets simultaneously, they can attract to each other through the intestinal walls. In the worst case scenario, this can lead to death.

Neodymium magnets are the most powerful magnets ever invented. Their strength can shock you.

To handle magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.

Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.

The strong magnetic field generated by neodymium magnets can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also destroy videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

Neodymium magnets are not recommended for 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.

Avoid bringing neodymium magnets close to a phone or GPS.

Magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.

Neodymium magnetic are delicate and can easily crack and get damaged.

Neodymium magnets are characterized by significant fragility. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. At the moment of connection between the magnets, small metal fragments can be dispersed in different directions.

Dust and powder from neodymium magnets are highly 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 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 become demagnetized at high temperatures.

Under specific conditions, Neodymium magnets can lose their magnetism when subjected to high temperatures.

Neodymium magnets can attract to each other, pinch the skin, and cause significant swellings.

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 a fracture.

In order for you to know how powerful neodymium magnets are and why they are so dangerous, see the article - Dangerous very strong neodymium magnets.
