Shopping tips

Still, caution is advised, as strong magnets can be fragile or may damage electronic devices such as smartphones or office electronics. Additionally, magnetic grippers should be properly matched to the mass and size of the item being lifted, to ensure stability and effectiveness.

Advantages as well as disadvantages of neodymium magnets NdFeB.

In addition to their exceptional pulling force, neodymium magnets offer the following advantages:

  • They virtually do not lose strength, because even after 10 years, the performance loss is only ~1% (according to literature),
  • They protect against demagnetization induced by ambient electromagnetic environments remarkably well,
  • Thanks to the shiny finish and silver coating, they have an elegant appearance,
  • They possess intense magnetic force measurable at the magnet’s surface,
  • Neodymium magnets are known for exceptionally strong magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the magnetic form),
  • With the option for tailored forming and targeted design, these magnets can be produced in various shapes and sizes, greatly improving engineering flexibility,
  • Important function in modern technologies – they are used in HDDs, electric drives, medical equipment as well as sophisticated instruments,
  • Thanks to their power density, small magnets offer high magnetic performance, with minimal size,

Disadvantages of rare earth magnets:

  • They are fragile when subjected to a powerful 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 cracks and reinforces its overall robustness,
  • Magnets lose pulling force when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible performance loss (influenced by the magnet’s profile). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
  • Magnets exposed to humidity can rust. Therefore, for outdoor applications, we recommend waterproof types made of non-metallic composites,
  • Limited ability to create internal holes in the magnet – the use of a magnetic holder is recommended,
  • Health risk due to small fragments may arise, if ingested accidentally, which is significant in the protection of children. Furthermore, tiny components from these devices can interfere with diagnostics if inside the body,
  • Due to the price of neodymium, their cost is relatively high,

Exercise Caution with Neodymium Magnets

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

Neodymium magnets generate strong magnetic fields that can damage 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. Do not forget to keep neodymium magnets away from these electronic devices.

The magnet coating is made of nickel, so be cautious 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

Keep neodymium magnets away from GPS and smartphones.

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.

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

To use magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.

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 is because many of these devices are equipped with a function that deactivates the device in a magnetic field.

Neodymium magnets are characterized by being fragile, which can cause them to become 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, small sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.

It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.

Neodymium magnets jump and touch each other mutually within a radius of several to almost 10 cm from each other.

 It is important to maintain neodymium magnets out of reach from youngest children.

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 can demagnetize at high temperatures.

Although magnets are generally resilient, their ability to retain their magnetic strength can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.

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.

Safety precautions!
