Anti-theft tag detachers, such as those utilizing neodymium magnets, are a key component of store security systems. They work by using a strong magnetic field to unlock the tag's mechanism, enabling quick and safe removal of the security tag at the checkout. They are highly effective because they allow for repeated use of tags, which is particularly useful in clothing stores, electronics shops, or those selling high-value alcohol. Advantages include ease of use, durability, and versatility, such as round, rectangular, or Sensormatic tags, like those in models RM®#6 from DHIT or Ultra 12000 Gs. They effectively minimize financial losses, reducing the possibility of goods being taken with an active security tag. It is crucial that detachers are stored in a location inaccessible to unauthorized individuals to enhance the security of the anti-theft system.

Advantages and disadvantages of neodymium magnets NdFeB.

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

They retain their attractive force for around ten years – the loss is just ~1% (based on simulations),
They remain magnetized despite exposure to magnetic noise,
In other words, due to the glossy gold coating, the magnet obtains an professional appearance,
They have exceptional magnetic induction on the surface of the magnet,
These magnets tolerate elevated temperatures, often exceeding 230°C, when properly designed (in relation to build),
Thanks to the flexibility in shaping and the capability to adapt to individual requirements, neodymium magnets can be created in various configurations, which broadens their application range,
Wide application in advanced technical fields – they serve a purpose in hard drives, electric motors, diagnostic apparatus along with sophisticated instruments,
Compactness – despite their small size, they provide high effectiveness, making them ideal for precision applications

Disadvantages of neodymium magnets:

They are prone to breaking when subjected to a powerful impact. If the magnets are exposed to mechanical hits, we recommend in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from breakage and additionally reinforces its overall resistance,
They lose magnetic force at increased temperatures. Most neodymium magnets experience permanent decline in strength when heated above 80°C (depending on the geometry and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
They rust in a damp environment, especially when used outside, we recommend using encapsulated magnets, such as those made of rubber,
The use of a protective casing or external holder is recommended, since machining internal cuts in neodymium magnets is risky,
Possible threat related to magnet particles may arise, when consumed by mistake, which is important in the health of young users. Furthermore, small elements from these magnets might hinder health screening if inside the body,
In cases of mass production, neodymium magnet cost may not be economically viable,

Exercise Caution with Neodymium Magnets

Avoid bringing neodymium magnets close to a phone or GPS.

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

Magnets made of neodymium are especially fragile, resulting in damage.

Neodymium magnets are characterized by significant fragility. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.

The magnet coating contains nickel, so be cautious if you have a nickel 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.

People with pacemakers are advised to avoid neodymium magnets.

Neodymium magnets produce strong magnetic fields that can interfere with the operation of a heart pacemaker. However, if the magnetic field does not affect the device, it can damage its components or deactivate the device when it is in a magnetic field.

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 will crack or alternatively crumble with careless joining to each other. Remember not to move them to each other or have them firmly in hands at a distance less than 10 cm.

Neodymium magnets are among the strongest magnets on Earth. The surprising force they generate between each other can shock you.

Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional damage to the magnets.

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

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, etc. devices. They can also damage devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.

Dust and powder from neodymium magnets are highly flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. Once crushed into fine powder or dust, this material becomes highly flammable.

Do not give neodymium magnets to youngest children.

Neodymium magnets are not toys. You cannot allow them to become toys for children. In the case of small magnets, they can be swallowed and cause choking. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.

Neodymium magnets can become demagnetized 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.

Safety precautions!

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