Shopping tips

As an example, magnetic strips are used to tidy up areas, e.g., in cooking areas to hold tools, or in workspaces to pin reminders.

Advantages and disadvantages of neodymium magnets NdFeB.

In addition to their pulling strength, neodymium magnets provide the following advantages:

  • They do not lose their even over approximately ten years – the reduction of power is only ~1% (according to tests),
  • They show exceptional resistance to demagnetization from external magnetic fields,
  • In other words, due to the shiny nickel coating, the magnet obtains an aesthetic appearance,
  • They possess significant magnetic force measurable at the magnet’s surface,
  • With the right combination of compounds, they reach increased thermal stability, enabling operation at or above 230°C (depending on the design),
  • With the option for customized forming and personalized design, these magnets can be produced in various shapes and sizes, greatly improving engineering flexibility,
  • Key role in modern technologies – they are utilized in computer drives, electromechanical systems, healthcare devices as well as technologically developed systems,
  • Relatively small size with high magnetic force – neodymium magnets offer strong power in tiny dimensions, which allows for use in compact constructions

Disadvantages of neodymium magnets:

  • They may fracture when subjected to a heavy impact. If the magnets are exposed to shocks, they should be placed in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from breakage and enhances its overall robustness,
  • High temperatures may significantly reduce the magnetic power of neodymium magnets. Typically, above 80°C, they experience permanent loss in performance (depending on shape). To prevent this, we offer heat-resistant magnets marked [AH], capable of working up to 230°C, which makes them perfect for high-temperature use,
  • Magnets exposed to wet conditions can degrade. Therefore, for outdoor applications, it's best to use waterproof types made of rubber,
  • The use of a protective casing or external holder is recommended, since machining fine details in neodymium magnets is difficult,
  • Potential hazard linked to microscopic shards may arise, especially if swallowed, which is significant in the family environments. It should also be noted that tiny components from these products have the potential to disrupt scanning if inside the body,
  • Due to expensive raw materials, their cost is above average,

Precautions

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

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

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.

Neodymium magnets can become demagnetized at high temperatures.

Although magnets have demonstrated their effectiveness up to 80°C or 175°F, the temperature can vary depending on the type, shape, and intended use of the specific magnet.

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.

Neodymium magnets are delicate and can easily crack and get damaged.

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 connection between the magnets, tiny sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.

Never bring neodymium magnets close to a phone and 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.

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 significant injury may occur. Magnets, depending on their size, can even cut off a finger or alternatively there can be a significant pressure or a fracture.

 It is essential to keep neodymium magnets away from children.

Neodymium magnets are not toys. You cannot allow them to become toys for children. In the case of small magnets, they can be swallowed and cause choking. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.

Dust and powder from neodymium magnets are flammable.

Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

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

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.

Safety rules!

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