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. 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 as well as disadvantages of neodymium magnets NdFeB.

In addition to their pulling strength, neodymium magnets provide the following advantages:

  • They virtually do not lose strength, because even after 10 years, the decline in efficiency is only ~1% (in laboratory conditions),
  • Their ability to resist magnetic interference from external fields is impressive,
  • In other words, due to the shiny gold coating, the magnet obtains an aesthetic appearance,
  • They have extremely strong magnetic induction on the surface of the magnet,
  • They are suitable for high-temperature applications, operating effectively at 230°C+ due to advanced heat resistance and form-specific properties,
  • With the option for fine forming and personalized design, these magnets can be produced in multiple shapes and sizes, greatly improving application potential,
  • Wide application in cutting-edge sectors – they serve a purpose in hard drives, electric motors, healthcare devices and other advanced devices,
  • Relatively small size with high magnetic force – neodymium magnets offer impressive pulling strength in small dimensions, which makes them useful in small systems

Disadvantages of rare earth magnets:

  • They may fracture when subjected to a heavy impact. If the magnets are exposed to physical collisions, it is advisable to use in a steel housing. The steel housing, in the form of a holder, protects the magnet from fracture and additionally increases its overall resistance,
  • They lose strength at increased temperatures. Most neodymium magnets experience permanent loss 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,
  • Magnets exposed to humidity can rust. Therefore, for outdoor applications, we recommend waterproof types made of rubber,
  • Limited ability to create precision features in the magnet – the use of a external casing is recommended,
  • Health risk related to magnet particles may arise, when consumed by mistake, which is notable in the health of young users. Additionally, miniature parts from these assemblies may hinder health screening once in the system,
  • Due to a complex production process, their cost is relatively high,

Highest magnetic holding forcewhat contributes to it?

The given holding capacity of the magnet means the highest holding force, calculated in the best circumstances, specifically:

  • using a steel plate with low carbon content, acting as a magnetic circuit closure
  • having a thickness of no less than 10 millimeters
  • with a smooth surface
  • in conditions of no clearance
  • with vertical force applied
  • at room temperature

Key elements affecting lifting force

The lifting capacity of a magnet is influenced by in practice key elements, ordered from most important to least significant:

  • 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.

* Lifting capacity testing was carried out on a smooth plate of optimal thickness, under perpendicular forces, however under parallel forces the holding force is lower. In addition, even a small distance {between} the magnet and the plate reduces the lifting capacity.

Precautions

Dust and powder from neodymium magnets are highly flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

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

The strong magnetic field generated by neodymium magnets can destroy 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.

Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their strength can shock you.

On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.

Keep neodymium magnets away from 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.

Never bring neodymium magnets close to a phone and GPS.

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

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 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.

In the situation of holding a finger in the path of a neodymium magnet, in such a case, a cut or a fracture may occur.

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.

  Neodymium magnets should not be around youngest children.

Not all neodymium magnets are toys, so do not let children play with them. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.

Neodymium magnetic are extremely fragile, resulting in breaking.

Neodymium magnets are characterized by significant fragility. Neodymium magnetic are made of metal and coated with a shiny nickel, but they are not as durable 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.

Exercise caution!
