Shopping tips

For example, magnetic mounts are applied in workshops to organize tools, while magnetic filters assist in removing small metal particles from streams in recovery or production. NeoCube beads, consisting of small neodymium elements, are used as logic puzzles or anti-stress toys, enhancing creativity and spatial abilities.

Advantages as well as disadvantages of neodymium magnets NdFeB.

Besides their high retention, neodymium magnets are valued for these benefits:

  • They virtually do not lose power, because even after ten years, the decline in efficiency is only ~1% (in laboratory conditions),
  • They show superior resistance to demagnetization from external magnetic fields,
  • In other words, due to the shiny nickel coating, the magnet obtains an professional appearance,
  • Magnetic induction on the surface of these magnets is very strong,
  • These magnets tolerate elevated temperatures, often exceeding 230°C, when properly designed (in relation to profile),
  • The ability for accurate shaping and adaptation to custom needs – neodymium magnets can be manufactured in many forms and dimensions, which enhances their versatility in applications,
  • Wide application in advanced technical fields – they serve a purpose in data storage devices, electric drives, medical equipment as well as technologically developed systems,
  • Compactness – despite their small size, they generate strong force, making them ideal for precision applications

Disadvantages of NdFeB magnets:

  • They can break when subjected to a heavy impact. If the magnets are exposed to shocks, we recommend in a metal holder. The steel housing, in the form of a holder, protects the magnet from cracks and additionally reinforces its overall resistance,
  • Magnets lose power when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible magnetic decay (influenced by the magnet’s dimensions). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
  • Due to corrosion risk in humid conditions, it is wise to use sealed magnets made of plastic for outdoor use,
  • Limited ability to create precision features in the magnet – the use of a housing is recommended,
  • Potential hazard related to magnet particles may arise, when consumed by mistake, which is important in the health of young users. It should also be noted that tiny components from these magnets can hinder health screening if inside the body,
  • Due to a complex production process, their cost is above average,

Precautions

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

Neodymium magnets can demagnetize at high temperatures.

Whilst Neodymium magnets can demagnetize at high temperatures, it's important to note that the extent of this effect can vary based on factors such as the magnet's material, shape, and intended application.

Keep neodymium magnets as far away as possible from GPS and smartphones.

Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, 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.

If the joining of neodymium magnets is not controlled, at that time they may crumble and also crack. You can't move them to each other. At a distance less than 10 cm you should hold them very strongly.

 It is essential to maintain neodymium magnets away from youngest children.

Not all neodymium magnets are toys, so do not let children play with them. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.

People with pacemakers are advised to avoid neodymium magnets.

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.

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.

Neodymium magnets are over 10 times stronger than ferrite magnets (the ones in speakers), and their strength can surprise 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 made of neodymium are especially fragile, which leads to shattering.

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 collision between the magnets, small sharp metal fragments 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.

Neodymium magnets generate intense magnetic fields that can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also destroy videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.

Be careful!

So that know how powerful neodymium magnets are and why they are so dangerous, see the article - Dangerous very strong neodymium magnets.
