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.

Our magnetic detacher is compatible with most (approx. 95-99%) standard magnetic systems. However, it will not work with mechanical clips (hook/SuperLock) or specific systems that are not magnetic.
Our opener has a magnetic field strength of approx. 12000-13000 Gauss (Gs). High induction guarantees quick and trouble-free customer service at the checkout without struggling with the clip.
We require an active VAT number to verify the legality of conducting business activity. We ensure that professional security equipment reaches legally operating sales points.
The detacher has threaded mounting holes, allowing stable and secure attachment. The magnet requires no electrical power, batteries, or cables. Fits any checkout stand without taking up much space.
A safe distance (min. 15-20 cm) should be kept from electronics, hard drives, and data carriers. The field itself is concentrated in the upper part of the device (in the socket) and fades quickly with distance.

Advantages as well as disadvantages of Nd2Fe14B magnets.

Advantages

Besides their stability, neodymium magnets are valued for these benefits:
  • Their magnetic field remains stable, and after approximately ten years it drops only by ~1% (theoretically),
  • Neodymium magnets are distinguished by highly resistant to loss of magnetic properties caused by magnetic disturbances,
  • In other words, due to the aesthetic finish of nickel, the element becomes visually attractive,
  • They feature high magnetic induction at the operating surface, which increases their power,
  • Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
  • Thanks to flexibility in designing and the capacity to customize to client solutions,
  • Universal use in electronics industry – they are commonly used in magnetic memories, brushless drives, advanced medical instruments, and technologically advanced constructions.
  • Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in compact constructions

Disadvantages

Drawbacks and weaknesses of neodymium magnets and proposals for their use:
  • To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
  • When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
  • Limited ability of creating nuts in the magnet and complicated forms - recommended is a housing - mounting mechanism.
  • Potential hazard resulting from small fragments of magnets are risky, when accidentally swallowed, which gains importance in the context of child health protection. Additionally, small components of these devices can be problematic in diagnostics medical after entering the body.
  • With budget limitations the cost of neodymium magnets is a challenge,

Pull force analysis

Best holding force of the magnet in ideal parameters – what contributes to it?

The lifting capacity listed is a result of laboratory testing conducted under standard conditions:
  • with the contact of a sheet made of low-carbon steel, guaranteeing maximum field concentration
  • whose thickness is min. 10 mm
  • with an polished touching surface
  • with zero gap (no impurities)
  • during detachment in a direction perpendicular to the mounting surface
  • at ambient temperature approx. 20 degrees Celsius

Magnet lifting force in use – key factors

In practice, the actual lifting capacity is determined by a number of factors, presented from most significant:
  • Clearance – the presence of foreign body (rust, tape, gap) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
  • 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 maximum value.
  • Steel thickness – insufficiently thick steel does not close the flux, causing part of the flux to be lost into the air.
  • Material type – ideal substrate is pure iron steel. Hardened steels may have worse magnetic properties.
  • Smoothness – full contact is possible only on smooth steel. Rough texture create air cushions, reducing force.
  • Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).

Lifting capacity was measured using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, however under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.

Safety rules for work with NdFeB magnets
Crushing risk

Large magnets can break fingers instantly. Never put your hand betwixt two strong magnets.

Handling guide

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

Danger to the youngest

NdFeB magnets are not intended for children. Eating several magnets can lead to them attracting across intestines, which constitutes a critical condition and necessitates urgent medical intervention.

Fire risk

Drilling and cutting of neodymium magnets carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Nickel allergy

Certain individuals have a sensitization to nickel, which is the standard coating for NdFeB magnets. Prolonged contact may cause an allergic reaction. We suggest wear protective gloves.

Maximum temperature

Control the heat. Exposing the magnet to high heat will destroy its properties and strength.

Impact on smartphones

Note: rare earth magnets produce a field that confuses sensitive sensors. Keep a separation from your mobile, device, and GPS.

Health Danger

Medical warning: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.

Electronic devices

Data protection: Neodymium magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, timepieces).

Beware of splinters

Neodymium magnets are sintered ceramics, meaning they are very brittle. Impact of two magnets leads to them shattering into small pieces.
