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. 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 as well as disadvantages of neodymium magnets NdFeB.

Besides their stability, neodymium magnets are valued for these benefits:

  • They virtually do not lose power, because even after ten years, the decline in efficiency is only ~1% (according to literature),
  • Their ability to resist magnetic interference from external fields is among the best,
  • The use of a polished gold surface provides a smooth finish,
  • They possess strong magnetic force measurable at the magnet’s surface,
  • Neodymium magnets are known for very high magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the magnetic form),
  • With the option for tailored forming and personalized design, these magnets can be produced in numerous shapes and sizes, greatly improving design adaptation,
  • Significant impact in advanced technical fields – they are utilized in data storage devices, electric motors, medical equipment or even sophisticated instruments,
  • Compactness – despite their small size, they provide high effectiveness, making them ideal for precision applications

Disadvantages of magnetic elements:

  • They are fragile when subjected to a heavy impact. If the magnets are exposed to shocks, it is advisable to use in a metal holder. The steel housing, in the form of a holder, protects the magnet from cracks and additionally increases its overall resistance,
  • They lose field intensity at high temperatures. Most neodymium magnets experience permanent reduction 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,
  • Due to corrosion risk in humid conditions, it is advisable to use sealed magnets made of synthetic coating for outdoor use,
  • Using a cover – such as a magnetic holder – is advised due to the restrictions in manufacturing fine shapes directly in the magnet,
  • Possible threat linked to microscopic shards may arise, in case of ingestion, which is significant in the protection of children. Furthermore, minuscule fragments from these products may interfere with diagnostics once in the system,
  • Due to the price of neodymium, their cost is above average,

Best holding force of the magnet in ideal parameterswhat it depends on?

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

  • using a steel plate with low carbon content, serving as a magnetic circuit closure
  • with a thickness of minimum 10 mm
  • with a smooth surface
  • with zero air gap
  • under perpendicular detachment force
  • at room temperature

Key elements affecting lifting force

The lifting capacity of a magnet depends on in practice key elements, ordered from most important to least significant:

  • Air gap between the magnet and the plate, because 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 tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the load capacity is reduced by as much as 75%. Moreover, even a slight gap {between} the magnet’s surface and the plate decreases the holding force.

Caution with Neodymium Magnets

Neodymium magnets can demagnetize at high temperatures.

In certain circumstances, Neodymium magnets can lose their magnetism when subjected to high temperatures.

  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 attract to each other, pinch the skin, and cause significant injuries.

Magnets will attract each other within a distance of several to about 10 cm from each other. Don't put your fingers in the path of magnet attraction, as a serious injury may occur. Depending on how large the neodymium magnets are, they can lead to a cut or a fracture.

Magnets made of neodymium are particularly fragile, resulting in their breakage.

Neodymium magnetic are extremely delicate, and by joining them in an uncontrolled manner, they will break. 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, sharp metal fragments can be dispersed in different directions.

Neodymium magnets are the most powerful magnets ever created, and their power can shock you.

To use magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.

Neodymium magnets should not be near people with pacemakers.

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.

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.

The magnet coating is made of nickel, so be cautious 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.

Under no circumstances should neodymium magnets be brought 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.

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

Neodymium magnets produce intense 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 destroy devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

Warning!
