Neodymium disc magnets offer a range of advantages compared to other magnet shapes, which make them the best choice for many applications:
Contact Surface: Due to their flat shape, disc magnets provide a significant contact surface with other elements, which can be beneficial in applications needing a stronger magnetic connection.
Applications in Technology: These magnets are often used 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, especially when you need to adhere the magnet to a surface.
Design Flexibility: The flat shape of the magnets allows designers with greater flexibility in placing them in devices, which can sometimes be more difficult with magnets of other shapes.
Stability: In some applications, the flat base of a disc magnet may provide 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 project 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 about 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 have 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 amplifies their universality in usage.
  • Wide application in the industry of new technologies – are utilized in HDD drives, electric motors, medical devices and other modern machines.

Disadvantages of neodymium magnets:

  • They are fragile when subjected to a strong impact. If the magnets are exposed to impacts, we recommend using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts and at the same time 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 reduction 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,
  • 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
  • Possible danger to health from tiny fragments of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting young children. Additionally, miniscule components of these devices are able to be problematic in medical diagnosis when they are in the body.

Safety Precautions

Neodymium magnets are over 10 times more powerful than ferrite magnets (the ones in speakers), and their strength can surprise you.

To use 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.

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.

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.

In the situation of holding a finger in the path of a neodymium magnet, in that situation, a cut or even a fracture may occur.

 It is essential to keep neodymium magnets away from youngest children.

Remember that neodymium magnets are not toys. Be cautious and make sure no child plays 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.

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, etc. devices. They can also damage devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

Magnets made of neodymium are highly delicate, they easily crack and can crumble.

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. 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.

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.

While Neodymium magnets can demagnetize 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.

Avoid bringing neodymium magnets close to a phone or GPS.

Intense magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.
