Shopping tips

Advantages as well as disadvantages of neodymium magnets NdFeB.

In addition to their long-term stability, neodymium magnets provide the following advantages:

  • Their strength remains stable, and after approximately ten years, it drops only by ~1% (according to research),
  • They show exceptional resistance to demagnetization from external field exposure,
  • By applying a bright layer of gold, the element gains a modern look,
  • They exhibit extremely high levels of magnetic induction near the outer area of the magnet,
  • With the right combination of materials, they reach significant thermal stability, enabling operation at or above 230°C (depending on the structure),
  • With the option for tailored forming and targeted design, these magnets can be produced in numerous shapes and sizes, greatly improving design adaptation,
  • Key role in modern technologies – they serve a purpose in hard drives, electromechanical systems, medical equipment or even high-tech tools,
  • Relatively small size with high magnetic force – neodymium magnets offer impressive pulling strength in compact dimensions, which makes them ideal in miniature devices

Disadvantages of neodymium magnets:

  • They are prone to breaking when subjected to a powerful impact. If the magnets are exposed to mechanical hits, they should be placed in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from damage and reinforces its overall resistance,
  • They lose field intensity at increased temperatures. Most neodymium magnets experience permanent decline in strength when heated above 80°C (depending on the form and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
  • Due to corrosion risk in humid conditions, it is wise to use sealed magnets made of plastic for outdoor use,
  • Limited ability to create internal holes in the magnet – the use of a magnetic holder is recommended,
  • Safety concern related to magnet particles may arise, in case of ingestion, which is notable in the family environments. It should also be noted that tiny components from these assemblies may hinder health screening if inside the body,
  • Due to a complex production process, their cost is considerably higher,

Safety Precautions

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

To handle 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.

Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.

The strong magnetic field generated by neodymium magnets can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also damage devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

The magnet coating contains nickel, so be cautious if you have a nickel 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 should not be around children.

Remember that 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.

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.

Under no circumstances should neodymium magnets be brought close to 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.

Neodymium magnets are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.

If the joining of neodymium magnets is not under control, 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 have them extremely strongly.

Neodymium magnets are not recommended for people with pacemakers.

Neodymium magnets generate strong magnetic fields. As a result, they 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 particularly delicate, which leads to their breakage.

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 pieces can be propelled in various directions at high speed. Eye protection is recommended.

Neodymium magnets can demagnetize at high temperatures.

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

Safety rules!

In order for you to know how powerful neodymium magnets are and why they are so dangerous, see the article - Dangerous very strong neodymium magnets.
