Advantages and disadvantages of neodymium magnets

Neodymium magnets, also known as NdFeB magnets, are currently the strongest permanent magnets available on the market. Their exceptional magnetic properties make them suitable for various industries, technologies, and everyday life. Below are the key advantages:

  • Immense attractive force: Even small neodymium magnets generate a very strong magnetic field.
  • High coercivity: They are resistant to demagnetization by external magnetic fields.
  • Wide operating temperature range: Standard neodymium magnets operate up to 80°C, with special versions up to 230°C.
  • Variety of shapes and sizes: Available in many forms, making them easy to adapt to specific applications.
  • Relatively low price compared to strength: They offer the best strength-to-price ratio among all magnets.
  • Longevity: With proper use, they retain their magnetic properties for many years.
  • Versatility of applications: From electric motors to speakers, separators, toys, and jewelry.

Despite numerous advantages, neodymium magnets also have certain disadvantages to consider:

  • Brittleness: They are hard but brittle and prone to cracking or chipping upon impact.
  • Susceptibility to corrosion: They require a protective coating (e.g., nickel, zinc) to prevent rusting.
  • Limited operating temperature for standard versions: Above the Curie temperature, they lose their magnetic properties.
  • Strong magnetic field can be dangerous: They can damage electronics, magnetic cards, and pose a risk of attracting metal objects with great force.
  • Difficulties in mechanical processing: Due to their hardness and brittleness, processing them is complex.

Handle Neodymium Magnets Carefully

Keep neodymium magnets away from the wallet, computer, and TV.

Strong 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.

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.

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

In the case of placing a finger in the path of a neodymium magnet, in such a case, a cut or a fracture may occur.

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 magnets can become demagnetized at high temperatures.

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

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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.

 Keep neodymium magnets away from youngest children.

Neodymium magnets are not toys. Do not allow children to play 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.

Magnets made of neodymium are characterized by their fragility, which can cause them to shatter.

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. 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.

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

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.

Neodymium magnets are not recommended for people with pacemakers.

Neodymium magnets produce strong magnetic fields that can interfere with the operation of a heart pacemaker. However, if the magnetic field does not affect the device, it can damage its components or deactivate the device when it is in a magnetic field.

So you are aware of why neodymium magnets are so dangerous, read the article titled How dangerous are strong neodymium magnets?.
