Neodymium disc magnets present a range of advantages in relation to other magnet shapes, which cause them to be the ideal choice for various uses:
Contact Surface: Thanks to their flat shape, disc magnets provide a larger contact surface with adjoining parts, which is beneficial in applications needing a stronger magnetic connection.
Applications in Technology: They are often employed in many devices, such as sensors, stepper motors, or speakers, where a thin and wide shape is essential for their operation.
Mounting: Their flat shape facilitates mounting, especially when you need to adhere the magnet to a surface.
Design Flexibility: The flat shape of the magnets gives designers with greater flexibility in placing them in constructions, which can be more difficult with magnets of more complex shapes.
Stability: In some applications, the flat base of a disc magnet can provide better stability, minimizing the risk of sliding or rotating. It should be noted that the optimal shape of a magnet depends on the specific application 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 strength over time - 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,
  • 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 various forms and dimensions, which amplifies their universality in usage.
  • Significant importance in advanced technologically fields – find application in HDD drives, electric motors, medical devices and other modern machines.

Disadvantages of neodymium magnets:

  • They are prone to breaking 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 steel housing. 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 shape and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
  • Due to their susceptibility to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
  • 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, in case of ingestion, which is crucial in the aspect of protecting young children. Additionally, tiny parts of these products can complicate diagnosis in case of swallowing.

Handle Neodymium Magnets with Caution

Neodymium magnets can attract to each other due to their immense internal force, causing the skin and other body parts to get pinched and resulting in significant injuries.

Magnets may crack or crumble with uncontrolled joining to each other. Remember not to approach them to each other or have them firmly in hands at a distance less than 10 cm.

Dust and powder from neodymium magnets are flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. Once crushed into fine powder or dust, this material becomes highly flammable.

Neodymium magnets are not recommended for 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.

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 magnetic are particularly delicate, which leads to damage.

Neodymium magnetic are delicate and will crack if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal as well as 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.

Never bring neodymium magnets close to a phone and GPS.

Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.

If you have a nickel allergy, avoid contact with neodymium magnets.

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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

Neodymium magnets can demagnetize at high temperatures.

Although magnets have shown to retain their effectiveness up to 80°C or 175°F, this temperature may vary depending on the type of material, shape, and intended use of the magnet.

  Do not give neodymium magnets to 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.

Neodymium magnets are the most powerful magnets ever created, and their power can surprise you.

Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.
