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 quickly detach tags, minimizing delays in customer service, 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 as well as disadvantages of neodymium magnets NdFeB.

Besides their magnetic performance, neodymium magnets are valued for these benefits:

  • They have stable power, and over more than 10 years their performance decreases symbolically – ~1% (according to theory),
  • They show superior resistance to demagnetization from external field exposure,
  • Thanks to the glossy finish and silver coating, they have an aesthetic appearance,
  • Magnetic induction on the surface of these magnets is impressively powerful,
  • Thanks to their enhanced temperature resistance, they can operate (depending on the form) even at temperatures up to 230°C or more,
  • The ability for custom shaping as well as adjustment to individual needs – neodymium magnets can be manufactured in multiple variants of geometries, which enhances their versatility in applications,
  • Wide application in modern technologies – they serve a purpose in computer drives, rotating machines, diagnostic apparatus as well as sophisticated instruments,
  • Thanks to their concentrated strength, small magnets offer high magnetic performance, in miniature format,

Disadvantages of NdFeB magnets:

  • They may fracture when subjected to a sudden impact. If the magnets are exposed to external force, they should be placed in a metal holder. The steel housing, in the form of a holder, protects the magnet from damage and additionally reinforces its overall strength,
  • Magnets lose pulling force when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible power drop (influenced by the magnet’s dimensions). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
  • Due to corrosion risk in humid conditions, it is recommended to use sealed magnets made of protective material for outdoor use,
  • The use of a protective casing or external holder is recommended, since machining fine details in neodymium magnets is risky,
  • Potential hazard related to magnet particles may arise, if ingested accidentally, which is notable in the context of child safety. Furthermore, minuscule fragments from these assemblies might interfere with diagnostics once in the system,
  • Due to expensive raw materials, their cost is above average,

Best holding force of the magnet in ideal parameterswhat affects it?

The given holding capacity of the magnet means the highest holding force, measured under optimal conditions, namely:

  • with the use of low-carbon steel plate acting as a magnetic yoke
  • with a thickness of minimum 10 mm
  • with a refined outer layer
  • in conditions of no clearance
  • in a perpendicular direction of force
  • under standard ambient temperature

Key elements affecting lifting force

Practical lifting force is dependent on elements, by priority:

  • Air gap between the magnet and the plate, since even a very small distance (e.g. 0.5 mm) can cause a drop in lifting force of up to 50%.
  • Direction of applied force, because the maximum lifting capacity is achieved under perpendicular application. The force required to slide the magnet along the plate is usually several times lower.
  • Thickness of the plate, as a plate that is too thin causes part of the magnetic flux not to be used and to remain wasted in the air.
  • Material of the plate, because higher carbon content lowers holding force, while higher iron content increases it. The best choice is steel with high magnetic permeability and high saturation induction.
  • Surface of the plate, because the more smooth and polished it is, the better the contact and consequently the greater the magnetic saturation.
  • Operating temperature, since all permanent magnets have a negative temperature coefficient. This means that at high temperatures they are weaker, while at sub-zero temperatures they become slightly stronger.

* Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the lifting capacity is smaller. In addition, even a small distance {between} the magnet and the plate lowers the lifting capacity.

Precautions

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 are among the strongest magnets on Earth. The astonishing force they generate between each other can surprise 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.

Magnets made of neodymium are particularly delicate, which leads to damage.

Neodymium magnets are highly delicate, and by joining them in an uncontrolled manner, they will crumble. 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 collision between the magnets, sharp metal fragments can be dispersed in different directions.

You should maintain neodymium magnets at a safe distance from the wallet, computer, and TV.

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. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.

Neodymium magnets can demagnetize at high temperatures.

Under specific conditions, Neodymium magnets may experience demagnetization when subjected to high temperatures.

Neodymium magnets can attract to each other, pinch the skin, and cause significant swellings.

Magnets attract each other within a distance of several to around 10 cm from each other. Don't put your fingers in the path of magnet attraction, as a serious injury may occur. Magnets, depending on their size, are able even cut off a finger or there can be a severe pressure or even a fracture.

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. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.

Under no circumstances should neodymium magnets be brought close to GPS and smartphones.

Strong fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.

 It is important to keep neodymium magnets away from youngest children.

Neodymium magnets are not toys. Be cautious and make sure no child plays with them. Small magnets can pose a serious choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing severe injuries, and even death.

The magnet is coated with nickel - be careful 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

Safety precautions!

Please see the article - What danger lies in neodymium magnets? You will learn how to handle them properly.
