Shopping tips

The most preferred holders for ID badges include options such as this UI 45x13x6 [Z323] / N38. They offer security and an aesthetic appearance. Magnetic mounts are valued as optimal because they are gentle on clothing, are simple to mount, and provide stable badge attachment. A model utilizing potent neodymium magnets and high-quality adhesive tapes, such as 3M tape, is exceptionally recommended.
No!, magnetic holders are contraindicated for individuals with cardiac pacemakers, as the strong magnetic field may disrupt their functioning. For such individuals, it is suggested to use non-magnetic holders, and we offer two such types in our range.

Advantages and disadvantages of neodymium magnets NdFeB.

In addition to their tremendous strength, neodymium magnets offer the following advantages:

  • Their power is durable, and after around 10 years, it drops only by ~1% (theoretically),
  • They remain magnetized despite exposure to strong external fields,
  • Because of the brilliant layer of gold, the component looks visually appealing,
  • The outer field strength of the magnet shows elevated magnetic properties,
  • They are suitable for high-temperature applications, operating effectively at 230°C+ due to advanced heat resistance and form-specific properties,
  • The ability for precise shaping and adjustment to specific needs – neodymium magnets can be manufactured in many forms and dimensions, which enhances their versatility in applications,
  • Important function in modern technologies – they are utilized in data storage devices, electric motors, healthcare devices along with sophisticated instruments,
  • Thanks to their concentrated strength, small magnets offer high magnetic performance, while occupying minimal space,

Disadvantages of rare earth magnets:

  • They are prone to breaking when subjected to a sudden impact. If the magnets are exposed to mechanical hits, they should be placed in a steel housing. The steel housing, in the form of a holder, protects the magnet from breakage , and at the same time strengthens its overall strength,
  • They lose field intensity at elevated temperatures. Most neodymium magnets experience permanent decline in strength when heated above 80°C (depending on the shape 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 rubber for outdoor use,
  • Limited ability to create threads in the magnet – the use of a external casing is recommended,
  • Possible threat from tiny pieces may arise, especially if swallowed, which is important in the family environments. Additionally, miniature parts from these magnets might disrupt scanning after being swallowed,
  • In cases of mass production, neodymium magnet cost is a challenge,

Caution with Neodymium Magnets

Neodymium magnetic are fragile as well as can easily break as well as shatter.

Neodymium magnets are characterized by considerable fragility. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. At the moment of connection between the magnets, small metal fragments can be dispersed in different directions.

Do not place neodymium magnets near a computer HDD, TV, and wallet.

Neodymium magnets produce intense magnetic fields that can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other 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.

Neodymium magnets are not recommended for 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.

Do not bring neodymium magnets 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.

Dust and powder from neodymium magnets are flammable.

Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.

Neodymium magnets can attract to each other due to their immense internal force, causing the skin and other body parts to get pinched and resulting in significant injuries.

Magnets will bounce and also contact together within a distance of several to almost 10 cm from each other.

Neodymium magnets can demagnetize at high temperatures.

Despite the fact that magnets have been found to maintain their efficacy up to temperatures of 80°C or 175°F, it's essential to consider that this threshold may fluctuate depending on the magnet's type, configuration, and intended usage.

  Neodymium magnets should not be around 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.

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

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

Safety rules!

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