Shopping tips

Our magnetic detacher is compatible with most (approx. 95-99%) standard magnetic systems. Some very rare securities require dedicated openers from the manufacturer.
Such power is necessary to release the spring lock inside the anti-theft clip. Weaker magnets (e.g., 6000 Gs) may not open modern, stronger clips.
For security and legal reasons, the offer is directed only to shops, boutiques, and enterprises. It is a shop equipment element, not a consumer product.
It can be used as a freestanding device or permanently mounted to prevent theft. It is a maintenance-free, mechanical device always ready for work. The aluminum housing is aesthetic, easy to clean, and durable.
Do not put credit cards or phones directly on the magnet. For store staff, the device is safe while maintaining basic safety rules.

Strengths and weaknesses of neodymium magnets.

Apart from their superior magnetic energy, neodymium magnets have these key benefits:

  • They retain full power for around ten years – the drop is just ~1% (based on simulations),
  • They do not lose their magnetic properties even under close interference source,
  • In other words, due to the smooth finish of nickel, the element gains a professional look,
  • They feature high magnetic induction at the operating surface, which affects their effectiveness,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
  • Considering the option of accurate shaping and adaptation to custom solutions, neodymium magnets can be produced in a variety of forms and dimensions, which makes them more universal,
  • Versatile presence in modern technologies – they are commonly used in magnetic memories, motor assemblies, medical equipment, and complex engineering applications.
  • Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Disadvantages of neodymium magnets:

  • At strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
  • They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • Due to limitations in producing threads and complicated shapes in magnets, we propose using a housing - magnetic mechanism.
  • Possible danger related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that tiny parts of these products are able to complicate diagnosis medical after entering the body.
  • Due to complex production process, their price is higher than average,

Maximum holding power of the magnet – what contributes to it?

The declared magnet strength concerns the peak performance, measured under laboratory conditions, namely:

  • using a plate made of high-permeability steel, acting as a magnetic yoke
  • possessing a massiveness of at least 10 mm to avoid saturation
  • with an ideally smooth touching surface
  • under conditions of gap-free contact (metal-to-metal)
  • for force applied at a right angle (in the magnet axis)
  • in temp. approx. 20°C

What influences lifting capacity in practice

It is worth knowing that the application force may be lower influenced by elements below, starting with the most relevant:

  • Air gap (between the magnet and the metal), as even a very small distance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
  • Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
  • Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
  • Steel type – mild steel attracts best. Alloy admixtures decrease magnetic permeability and lifting capacity.
  • Surface condition – ground elements guarantee perfect abutment, which improves field saturation. Uneven metal weaken the grip.
  • Thermal environment – temperature increase results in weakening of force. Check the maximum operating temperature for a given model.

* Lifting capacity was measured with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under shearing force the load capacity is reduced by as much as 75%. Moreover, even a slight gap {between} the magnet and the plate lowers the load capacity.

Safe handling of NdFeB magnets

Handling rules

Handle with care. Rare earth magnets attract from a long distance and connect with massive power, often faster than you can move away.

Fragile material

Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.

Product not for children

Neodymium magnets are not intended for children. Swallowing several magnets can lead to them pinching intestinal walls, which poses a severe health hazard and requires immediate surgery.

Crushing risk

Watch your fingers. Two large magnets will snap together instantly with a force of massive weight, crushing everything in their path. Be careful!

GPS Danger

A strong magnetic field disrupts the functioning of compasses in smartphones and GPS navigation. Keep magnets close to a smartphone to prevent breaking the sensors.

Fire risk

Drilling and cutting of neodymium magnets poses a fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.

Danger to pacemakers

Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.

Do not overheat magnets

Regular neodymium magnets (grade N) undergo demagnetization when the temperature exceeds 80°C. The loss of strength is permanent.

Sensitization to coating

Studies show that the nickel plating (the usual finish) is a common allergen. If you have an allergy, avoid touching magnets with bare hands and opt for encased magnets.

Safe distance

Data protection: Strong magnets can ruin payment cards and delicate electronics (heart implants, medical aids, mechanical watches).

Security!
