Frequently asked questions

How much will a magnetic holder hold in practice?
The catalogue value assumes full contact with smooth steel at least 10 mm thick and a perpendicular pull. Thinner sheet, paint, rust and surface irregularities reduce it considerably: on 1 mm sheet about half remains. Lifting and vertical mounting call for an additional safety margin.
Will a holder work on stainless steel?
Not on austenitic grades 304 and 316 — they are effectively non-magnetic. It will not work on aluminium, copper or brass either. Those materials need a mechanical gripper.
Which coating for which conditions?
Nickel-copper-nickel (NiCuNi) is the standard and covers most applications. Epoxy is used for damp environments and outdoor work, zinc is sufficient for dry interiors. Holders in a steel housing or in rubber also protect the magnet against impact.

Unlike safety pins or pins, magnetic fastening leaves no marks or holes on the material. This ensures elegance and wearing comfort, without the risk of pricking yourself or ruining clothes. It is the most frequently chosen type of fastening in corporations, hotels, and banks.
Construction includes a module with strong neodymium magnets in plastic and a plate with self-adhesive tape. You stick your badge on the plate, and the magnet holds it through the clothing material. The plastic magnet housing is pleasant to the touch, smooth, and safe for the user.
Attraction force is sufficient to hold the badge even on winter clothing. We offer versions with two or three magnets, which further increases stability and strength.
For people with a pacemaker, we recommend traditional fasteners on a lanyard, clip, or safe pin. Healthy users can use badges without worrying about their well-being.
Yes, we are a direct importer and fulfill large wholesale orders. You can order samples to check the quality before a larger purchase.

Pros and cons of neodymium magnets.

Strengths

Apart from their superior holding force, neodymium magnets have these key benefits:
  • Their strength remains stable, and after around 10 years it decreases only by ~1% (theoretically),
  • Magnets perfectly resist against loss of magnetization caused by ambient magnetic noise,
  • The use of an refined layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
  • They show high magnetic induction at the operating surface, which increases their power,
  • Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures approaching 230°C and above...
  • Thanks to flexibility in shaping and the ability to modify to complex applications,
  • Universal use in modern industrial fields – they are utilized in mass storage devices, motor assemblies, advanced medical instruments, as well as multitasking production systems.
  • Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in small systems

Weaknesses

Disadvantages of NdFeB magnets:
  • Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a special holder, which not only secures them against impacts but also raises their durability
  • When exposed to high temperature, neodymium magnets experience a drop in power. 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
  • Magnets exposed to a humid environment can rust. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
  • Limited ability of making threads in the magnet and complicated shapes - recommended is cover - magnet mounting.
  • Health risk related to microscopic parts of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, tiny parts of these magnets are able to disrupt the diagnostic process medical after entering the body.
  • High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities

Holding force characteristics

Maximum lifting capacity of the magnet – what affects it?

The load parameter shown concerns the maximum value, recorded under laboratory conditions, namely:
  • on a block made of structural steel, effectively closing the magnetic flux
  • possessing a thickness of minimum 10 mm to avoid saturation
  • with a plane free of scratches
  • without the slightest clearance between the magnet and steel
  • during pulling in a direction perpendicular to the mounting surface
  • at ambient temperature room level

Determinants of practical lifting force of a magnet

In practice, the actual holding force is determined by several key aspects, presented from crucial:
  • Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
  • Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
  • Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
  • Plate material – low-carbon steel attracts best. Alloy admixtures decrease magnetic properties and lifting capacity.
  • Surface structure – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
  • Operating temperature – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the holding force is lower. Additionally, even a slight gap between the magnet and the plate lowers the lifting capacity.

Precautions when working with neodymium magnets
GPS and phone interference

Be aware: rare earth magnets generate a field that interferes with precision electronics. Keep a safe distance from your phone, device, and navigation systems.

Handling rules

Be careful. Neodymium magnets attract from a distance and snap with huge force, often quicker than you can move away.

Pinching danger

Big blocks can smash fingers in a fraction of a second. Never place your hand betwixt two attracting surfaces.

Electronic devices

Data protection: Strong magnets can ruin payment cards and sensitive devices (pacemakers, medical aids, timepieces).

Power loss in heat

Watch the temperature. Heating the magnet to high heat will ruin its properties and pulling force.

Danger to the youngest

Product intended for adults. Small elements pose a choking risk, leading to serious injuries. Keep out of reach of kids and pets.

Material brittleness

Despite metallic appearance, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.

Fire risk

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

Skin irritation risks

Studies show that nickel (the usual finish) is a strong allergen. If your skin reacts to metals, refrain from direct skin contact or select versions in plastic housing.

Warning for heart patients

People with a ICD should keep an safe separation from magnets. The magnetism can stop the functioning of the implant.
