Shopping tips

It is essential to choose magnetic accessories from trusted suppliers, which ensures high quality and reliability during use.

Advantages as well as disadvantages of neodymium magnets NdFeB.

In addition to their exceptional pulling force, neodymium magnets offer the following advantages:

  • Their magnetic field remains stable, and after around 10 years, it drops only by ~1% (according to research),
  • They remain magnetized despite exposure to strong external fields,
  • Because of the brilliant layer of silver, the component looks aesthetically refined,
  • They have extremely strong magnetic induction on the surface of the magnet,
  • With the right combination of materials, they reach increased thermal stability, enabling operation at or above 230°C (depending on the structure),
  • With the option for fine forming and personalized design, these magnets can be produced in multiple shapes and sizes, greatly improving application potential,
  • Wide application in new technology industries – they are utilized in hard drives, electric motors, medical equipment and technologically developed systems,
  • Compactness – despite their small size, they provide high effectiveness, making them ideal for precision applications

Disadvantages of neodymium magnets:

  • They can break when subjected to a heavy impact. If the magnets are exposed to mechanical hits, we recommend in a metal holder. The steel housing, in the form of a holder, protects the magnet from cracks and additionally enhances its overall robustness,
  • They lose magnetic force at elevated temperatures. Most neodymium magnets experience permanent degradation in strength when heated above 80°C (depending on the shape and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
  • Magnets exposed to damp air can corrode. Therefore, for outdoor applications, it's best to use waterproof types made of rubber,
  • Using a cover – such as a magnetic holder – is advised due to the difficulty in manufacturing complex structures directly in the magnet,
  • Possible threat from tiny pieces may arise, when consumed by mistake, which is significant in the health of young users. Moreover, tiny components from these magnets may complicate medical imaging when ingested,
  • High unit cost – neodymium magnets are more expensive than other types of magnets (e.g., ferrite), which may limit large-scale applications

Handle Neodymium Magnets Carefully

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

Strong magnetic fields emitted by neodymium magnets can damage 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.

Never bring neodymium magnets close to a phone and GPS.

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.

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

Magnets will attract each other within a distance of several to about 10 cm from each other. Remember not to insert fingers between magnets or in their path when attract. Depending on how large the neodymium magnets are, they can lead to a cut or alternatively a fracture.

Neodymium magnets can demagnetize at high temperatures.

Even though magnets have been observed to maintain their efficacy up to temperatures of 80°C or 175°F, it's essential to consider that this threshold may fluctuate depending on the magnet's type, configuration, and intended usage.

Keep neodymium magnets away from people with pacemakers.

Neodymium magnets produce strong magnetic fields that can interfere 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.

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 magnetic are highly delicate, they easily crack and can become damaged.

Neodymium magnets are characterized by considerable fragility. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.

The magnet is coated with nickel. Therefore, exercise caution if you have an 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.

 Keep neodymium magnets far from children.

Neodymium magnets are not toys. You cannot allow them to become toys for children. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.

Neodymium magnets are the most powerful, most remarkable magnets on earth, and the surprising force between them can surprise you at first.

Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional disruption to the magnets.

Warning!
