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 protect against demagnetization caused by external magnetic sources extremely well,
  • By applying a shiny coating of nickel, gold, or silver, the element gains 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 shape) even at temperatures up to 230°C and above...
  • The ability for precise shaping or customization to specific needs – neodymium magnets can be produced in a wide range of shapes and sizes, which amplifies their universality in usage.
  • Key role in modern technologies – find application in hard drives, electric drive mechanisms, medical devices or very advanced devices.

Disadvantages of neodymium magnets:

  • They can break 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 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,
  • They rust in a humid environment - during outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
  • 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 pose a threat, in case of ingestion, which is crucial in the context of children's health. It's also worth noting that small elements of these magnets are able to be problematic in medical diagnosis in case of swallowing.

Safety Precautions

Keep neodymium magnets away from people with pacemakers.

Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.

Avoid contact with neodymium magnets 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.

  Neodymium magnets should not be around youngest 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.

Magnets made of neodymium are fragile and can easily break as well as get damaged.

Neodymium magnetic are fragile as well as 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. At the moment of collision between the magnets, small sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.

Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.

Magnetic fields generated by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other similar devices. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.

Neodymium magnets can demagnetize at high temperatures.

Although magnets have shown to retain their effectiveness up to 80°C or 175°F, this temperature may vary depending on the type of material, shape, and intended use of the magnet.

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

On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.

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

If joining of neodymium magnets is not under control, then they may crumble and crack. Remember not to move them to each other or have them firmly in hands at a distance less than 10 cm.

Avoid bringing neodymium magnets close to a phone or GPS.

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

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.
