Advantages and disadvantages of neodymium magnets NdFeB.

Apart from immense strength, 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 extremely resistant to demagnetization by external magnetic field,
  • In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
  • They possess very 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.
  • Wide application in modern technologies – find application in HDD drives, electric motors, medical apparatus or various technologically advanced devices.

Disadvantages of neodymium magnets:

  • They are fragile when subjected to a powerful 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,
  • Magnets lose their power due to exposure to high temperatures. In most cases, when the temperature exceeds 80°C, these magnets experience permanent loss 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,
  • They rust in a humid environment - during outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
  • The use of a cover - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
  • Potential hazard to health from tiny fragments of magnets are risky, if swallowed, which is crucial in the context of child safety. Furthermore, tiny parts of these products can be problematic in medical diagnosis in case of swallowing.

Exercise Caution with Neodymium Magnets

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.

Neodymium magnets can become demagnetized at high temperatures.

In certain circumstances, Neodymium magnets can lose their magnetism when subjected to high temperatures.

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

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

People with pacemakers are advised to avoid neodymium magnets.

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.

The magnet coating is made of nickel, so be cautious if you have an 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 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.

Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.

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

Keep neodymium magnets away from GPS and smartphones.

Neodymium magnets are a source of strong magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

Neodymium magnets are extremely fragile, they easily break as well as can crumble.

In the event of a collision between two neodymium magnets, it can result in them getting chipped. Despite being made of metal and coated with a shiny nickel plating, they are not as hard as steel. 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.

  Neodymium magnets should not be in the vicinity children.

Neodymium magnets are not toys. Be cautious and make sure no child plays with them. They can be a significant choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing severe injuries, and even death.

In order for you to know how strong neodymium magnets are and why they are so dangerous, read the article - Dangerous very strong neodymium magnets.
