Shopping tips

Magnetic accessories, such as magnetic holders, separators, neodymium beads, or tapes, are widely applied in various areas, from industrial to domestic applications. They function thanks to a powerful magnetic field, generated by NdFeB magnets or standard magnets, allowing holding of components, sorting of resources, or constructing unusual forms.

Advantages and disadvantages of neodymium magnets NdFeB.

In addition to their exceptional field intensity, neodymium magnets offer the following advantages:

  • They virtually do not lose strength, because even after ten years, the decline in efficiency is only ~1% (according to literature),
  • They are highly resistant to demagnetization caused by external magnetic fields,
  • Thanks to the glossy finish and silver coating, they have an aesthetic appearance,
  • They exhibit extremely high levels of magnetic induction near the outer area of the magnet,
  • With the right combination of compounds, they reach significant thermal stability, enabling operation at or above 230°C (depending on the structure),
  • The ability for custom shaping or adaptation to specific needs – neodymium magnets can be manufactured in a wide range of shapes and sizes, which enhances their versatility in applications,
  • Important function in cutting-edge sectors – they serve a purpose in computer drives, electric drives, diagnostic apparatus along with sophisticated instruments,
  • Relatively small size with high magnetic force – neodymium magnets offer strong power in tiny dimensions, which makes them useful in compact constructions

Disadvantages of rare earth magnets:

  • They can break when subjected to a heavy impact. If the magnets are exposed to shocks, they should be placed in a protective case. The steel housing, in the form of a holder, protects the magnet from fracture , and at the same time increases its overall strength,
  • High temperatures may significantly reduce the magnetic power of neodymium magnets. Typically, above 80°C, they experience permanent weakening in performance (depending on form). 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,
  • They rust in a wet environment. If exposed to rain, we recommend using encapsulated magnets, such as those made of polymer,
  • The use of a protective casing or external holder is recommended, since machining internal cuts in neodymium magnets is difficult,
  • Possible threat related to magnet particles may arise, when consumed by mistake, which is important in the protection of children. It should also be noted that minuscule fragments from these devices can hinder health screening if inside the body,
  • In cases of large-volume purchasing, neodymium magnet cost may be a barrier,

Exercise Caution with Neodymium Magnets

Keep neodymium magnets away from people with pacemakers.

Neodymium magnets generate strong magnetic fields. As a result, they 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.

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.

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

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

Neodymium magnets generate strong magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

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

Neodymium magnets produce strong magnetic fields that can damage 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 away from these electronic devices.

Neodymium magnets can become demagnetized at high temperatures.

In certain circumstances, Neodymium magnets may experience demagnetization when subjected to high temperatures.

Magnets made of neodymium are highly susceptible to damage, leading to shattering.

Neodymium magnetic are highly fragile, and by joining them in an uncontrolled manner, they will crack. Neodymium magnets are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of collision between the magnets, sharp metal fragments can be dispersed in different directions.

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

Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.

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.

Magnets may crack or alternatively crumble with careless connecting to each other. Remember not to move them to each other or hold them firmly in hands at a distance less than 10 cm.

  Neodymium magnets should not be in the vicinity youngest children.

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

Exercise caution!
