Advantages and disadvantages of neodymium magnets NdFeB.

In addition to immense power, neodymium magnets have the following advantages:

  • They do not lose their power (of the magnet). After about 10 years, their power decreases by only ~1% (theoretically),
  • They protect against demagnetization caused by external magnetic field extremely well,
  • In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
  • They exhibit very high magnetic induction on the surface of the magnet,
  • Magnetic neodymium magnets are characterized by very high magnetic induction on the surface of the magnet and can operate (depending on the form) even at temperatures of 230°C or higher...
  • Thanks to the flexibility in shaping or the ability to adapt to specific requirements – neodymium magnets can be produced in many variants of shapes or sizes, which enhances their versatility in applications.
  • Significant importance in the industry of new technologies – find application in hard drives, electric motors, medical devices or other highly developed apparatuses.

Disadvantages of neodymium magnets:

  • They can break as they are extremely fragile when subjected to a powerful 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 also 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 form 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 suggest 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 associated with microscopic parts of magnets are risky, if swallowed, which is particularly important in the context of children's health. It's also worth noting that miniscule components of these products can hinder the diagnostic process in case of swallowing.

We Recommend Caution with Neodymium Magnets

You should maintain neodymium magnets at a safe distance from the wallet, computer, and TV.

Neodymium magnets produce intense magnetic fields that 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 devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

Neodymium magnets can demagnetize at high temperatures.

Under specific conditions, Neodymium magnets may experience demagnetization when subjected to high temperatures.

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

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 delicate and can easily break as well as shatter.

In the event of a collision between two neodymium magnets, it can result in them getting chipped. They are coated with a shiny nickel plating similar to steel, but they are not as hard. At the moment of collision between the magnets, small sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.

The magnet coating contains nickel, so be cautious 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.

Dust and powder from neodymium magnets are 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 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, as a major injury may occur. Magnets, depending on their size, are able even cut off a finger or there can be a serious pressure or a fracture.

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

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

Do not bring neodymium magnets close to GPS and smartphones.

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.

Neodymium magnets should not be near 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.

Please see the article - What danger lies in neodymium magnets? You will learn how to handle them properly.
