Frequently asked questions

Do you make magnets to order?
Yes. We make sizes and shapes outside the catalogue, in grades from N27 to N55 and in high-temperature versions. Lead time depends on the shape and batch size — for rings it is 25–35 days.
Which coating should I choose?
NiCuNi is the standard and covers most applications. Zinc is cheaper and suits dry interiors, epoxy suits damp conditions and outdoor use, gold is chosen where appearance matters. An uncoated magnet corrodes in humid air within a few hours.
Will I receive documentation with my order?
Yes. We issue a REACH statement for the article, a declaration of conformity for the packaging under PPWR, and a certificate of measured magnetic parameters. Documents are issued on request, for a specific article or order number.

Thanks to the universal socket profile, it fits many types of clips used in shops. Some very rare securities require dedicated openers from the manufacturer.
It is an extremely strong neodymium magnet, many times stronger than standard household magnets. High induction guarantees quick and trouble-free customer service at the checkout without struggling with the clip.
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. The magnet requires no electrical power, batteries, or cables. The aluminum housing is aesthetic, easy to clean, and durable.
The detacher generates a very strong magnetic field that can permanently damage payment cards, mechanical watches, or phones. For store staff, the device is safe while maintaining basic safety rules.

Strengths as well as weaknesses of rare earth magnets.

Strengths

Besides their magnetic performance, neodymium magnets are valued for these benefits:
  • They do not lose strength, even after approximately ten years – the drop in lifting capacity is only ~1% (according to tests),
  • Magnets effectively resist against demagnetization caused by foreign field sources,
  • The use of an metallic coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
  • Magnetic induction on the working layer of the magnet is strong,
  • 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...
  • Possibility of detailed shaping as well as modifying to atypical applications,
  • Versatile presence in modern industrial fields – they are commonly used in hard drives, brushless drives, precision medical tools, and technologically advanced constructions.
  • Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Cons

Disadvantages of neodymium magnets:
  • Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a special holder, which not only protects them against impacts but also increases their durability
  • When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
  • Limited ability of creating threads in the magnet and complicated shapes - preferred is a housing - mounting mechanism.
  • Health risk related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child health protection. It is also worth noting that tiny parts of these magnets are able to be problematic in diagnostics medical when they are in the body.
  • Due to expensive raw materials, their price is relatively high,

Holding force characteristics

Maximum lifting capacity of the magnet – what it depends on?

The force parameter is a result of laboratory testing performed under standard conditions:
  • on a block made of structural steel, optimally conducting the magnetic field
  • possessing a massiveness of min. 10 mm to ensure full flux closure
  • with a surface free of scratches
  • with total lack of distance (without paint)
  • for force acting at a right angle (pull-off, not shear)
  • at ambient temperature room level

What influences lifting capacity in practice

Effective lifting capacity impacted by working environment parameters, mainly (from priority):
  • Gap between surfaces – every millimeter of distance (caused e.g. by veneer or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
  • Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
  • Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
  • Steel type – mild steel gives the best results. Alloy admixtures decrease magnetic properties and lifting capacity.
  • Base smoothness – the more even the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
  • Thermal conditions – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity was measured using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate lowers the holding force.

Safe handling of neodymium magnets
Safe distance

Data protection: Neodymium magnets can damage data carriers and sensitive devices (pacemakers, medical aids, timepieces).

Keep away from children

Always store magnets away from children. Risk of swallowing is high, and the consequences of magnets clamping inside the body are life-threatening.

Implant safety

Medical warning: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.

Material brittleness

Despite metallic appearance, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.

Handling guide

Be careful. Neodymium magnets attract from a long distance and connect with huge force, often faster than you can react.

Allergy Warning

Allergy Notice: The nickel-copper-nickel coating consists of nickel. If skin irritation happens, cease handling magnets and wear gloves.

Precision electronics

Remember: rare earth magnets produce a field that interferes with precision electronics. Maintain a safe distance from your mobile, tablet, and GPS.

Do not drill into magnets

Powder created during grinding of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.

Heat warning

Regular neodymium magnets (grade N) undergo demagnetization when the temperature goes above 80°C. This process is irreversible.

Pinching danger

Pinching hazard: The pulling power is so great that it can result in blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
