Shopping tips

Anti-theft tag detachers, such as those utilizing neodymium magnets, are a key component of store security systems. Their principle of operation relies on neodymium magnets that neutralize the magnetic lock in the tag, 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. Their benefits include compact size, high reliability, and the ability to open various tag types, such as round, rectangular, or Sensormatic tags, like those in models RM®#6 from DHIT or Ultra 12000 Gs. Additionally, they provide strong protection against theft, 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

Neodymium magnets, also known as NdFeB magnets, are currently the strongest permanent magnets available on the market. Their exceptional magnetic properties make them suitable for various industries, technologies, and everyday life. Below are the key advantages:

  • Immense attractive force: Even small neodymium magnets generate a very strong magnetic field.
  • High coercivity: They are resistant to demagnetization by external magnetic fields.
  • Wide operating temperature range: Standard neodymium magnets operate up to 80°C, with special versions up to 230°C.
  • Variety of shapes and sizes: Available in many forms, making them easy to adapt to specific applications.
  • Relatively low price compared to strength: They offer the best strength-to-price ratio among all magnets.
  • Longevity: With proper use, they retain their magnetic properties for many years.
  • Versatility of applications: From electric motors to speakers, separators, toys, and jewelry.

Despite numerous advantages, neodymium magnets also have certain disadvantages to consider:

  • Brittleness: They are hard but brittle and prone to cracking or chipping upon impact.
  • Limited operating temperature for standard versions: Above the Curie temperature, they lose their magnetic properties.
  • Strong magnetic field can be dangerous: They can damage electronics, magnetic cards, and pose a risk of attracting metal objects with great force.
  • Difficulties in mechanical processing: Due to their hardness and brittleness, processing them is complex.

Exercise Caution with Neodymium Magnets

Never bring neodymium magnets close to a phone and GPS.

Magnetic fields can interfere with compasses and magnetometers used in aviation and maritime navigation, as well as internal compasses of smartphones and GPS devices. There are neodymium magnets in every smartphone, for example, in the microphone and speakers.

Neodymium magnetic are highly susceptible to damage, leading to their cracking.

In the event of a collision between two neodymium magnets, it can result in them getting chipped. Despite being made of metal as well as coated with a shiny nickel plating, they are not as hard as steel. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.

If you have a nickel allergy, avoid contact with neodymium magnets.

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.

While 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 away from TV, wallet, and computer HDD.

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 videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.

People with pacemakers are advised to avoid neodymium magnets.

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. 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 swellings.

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

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.

 Keep neodymium magnets far from youngest children.

Neodymium magnets are not toys. You cannot allow them to become toys for children. Small magnets pose a serious choking hazard or can attract to each other in the intestines. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.
