Neodymium disc magnets present a range of advantages in relation to other magnet shapes, which cause them to be the best choice for numerous projects:
Contact Surface: Thanks to their flat shape, disc magnets guarantee a significant contact surface with adjoining parts, which is beneficial in applications needing a stronger magnetic connection.
Applications in Technology: The magnets are often used in various devices, like sensors, stepper motors, or speakers, where a thin and wide shape is crucial for their operation.
Mounting: This form's flat shape facilitates mounting, especially when it's necessary to adhere the magnet to another surface.
Design Flexibility: The flat shape of the magnets gives designers with significant 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 may offer better stability, reducing the risk of shifting or rotating. However, it's important to remember that the optimal shape of a magnet is dependent on the specific application and requirements. In certain cases, other shapes, like 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 power over time - after 10 years, their power decreases by only ~1% (theoretically),
  • They are exceptionally resistant to demagnetization caused by an external magnetic field,
  • In other words, thanks to the glossy nickel, gold, or silver finish, the element gains an aesthetic appearance,
  • They exhibit extremely high magnetic induction on the surface of the magnet,
  • Thanks to their high temperature resistance, they can operate (depending on the form) even at temperatures up to 230°C and above...
  • Thanks to the flexibility in shaping and the ability to adapt to specific requirements – neodymium magnets can be produced in various forms and dimensions, which enhances their versatility in applications.
  • Key role in modern technologies – find application in computer drives, electric motors, medical apparatus or very advanced devices.

Disadvantages of neodymium magnets:

  • They can break when subjected to a strong impact. If the magnets are exposed to impacts, we recommend using magnets in a metal holder. 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 loss in strength (although it is dependent on the form 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,
  • 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,
  • Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
  • Potential hazard to health from tiny fragments of magnets are risky, when accidentally ingested, which is crucial in the context of children's health. Furthermore, tiny parts of these devices are able to complicate diagnosis when they are in the body.

Caution with Neodymium Magnets

Under no circumstances should neodymium magnets be brought close to GPS and smartphones.

Neodymium magnets generate strong magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

You should maintain neodymium magnets at a safe distance 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. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.

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

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.

Neodymium magnets can become demagnetized at high temperatures.

Despite the general resilience of magnets, their ability to maintain their magnetic potency can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.

Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their strength can shock you.

Familiarize yourself with our information to correctly handle these magnets and avoid significant swellings to your body and prevent damage to the magnets.

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

Not all neodymium magnets are toys, so do not let children play with them. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.

Neodymium magnets are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.

Neodymium magnets jump and touch each other mutually within a distance of several to around 10 cm from each other.

Neodymium magnets should not be near people with pacemakers.

Neodymium magnets produce strong magnetic fields that can interfere with the operation of a heart pacemaker. However, if the magnetic field does not affect the device, it can damage its components or deactivate the device when it is in a magnetic field.

Magnets made of neodymium are delicate and can easily break as well as shatter.

Neodymium magnets 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. 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.
