Unlike safety pins or pins, magnetic fastening leaves no marks or holes on the material. The badge holds stably, does not tilt or hang, which improves employee image. 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. Magnets are hidden in an aesthetic plastic housing that does not irritate the skin.
Yes, the neodymium magnets used are very strong and hold even through thick materials. 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. Contact us to receive an individual B2B offer tailored to your company's needs.

Advantages as well as disadvantages of rare earth magnets.

Advantages

Besides their high retention, neodymium magnets are valued for these benefits:
  • Their power remains stable, and after approximately ten years it decreases only by ~1% (according to research),
  • Neodymium magnets prove to be exceptionally resistant to demagnetization caused by external magnetic fields,
  • In other words, due to the aesthetic finish of nickel, the element is aesthetically pleasing,
  • Magnets exhibit exceptionally strong magnetic induction on the outer layer,
  • Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
  • Possibility of exact modeling and modifying to concrete needs,
  • Significant place in electronics industry – they are utilized in hard drives, electric motors, precision medical tools, as well as technologically advanced constructions.
  • Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in miniature devices

Weaknesses

Disadvantages of neodymium magnets:
  • They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
  • We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
  • Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
  • Due to limitations in producing nuts and complicated forms in magnets, we recommend using cover - magnetic mount.
  • Health risk related to microscopic parts of magnets are risky, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these devices are able to complicate diagnosis medical when they are in the body.
  • High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities

Lifting parameters

Magnetic strength at its maximum – what contributes to it?

The load parameter shown concerns the peak performance, obtained under optimal environment, specifically:
  • on a block made of structural steel, perfectly concentrating the magnetic field
  • possessing a massiveness of at least 10 mm to ensure full flux closure
  • with a surface free of scratches
  • with total lack of distance (no impurities)
  • during pulling in a direction vertical to the mounting surface
  • in neutral thermal conditions

Practical lifting capacity: influencing factors

In practice, the real power depends on a number of factors, ranked from crucial:
  • Gap between magnet and steel – every millimeter of separation (caused e.g. by varnish or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
  • Force direction – catalog parameter refers to detachment vertically. When attempting to slide, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
  • Steel thickness – too thin steel does not accept the full field, causing part of the flux to be escaped to the other side.
  • Material type – the best choice is pure iron steel. Hardened steels may generate lower lifting capacity.
  • Surface condition – ground elements ensure maximum contact, which improves force. Rough surfaces weaken the grip.
  • Temperature – heating the magnet results in weakening of force. It is worth remembering the maximum operating temperature for a given model.

Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate lowers the load capacity.

Precautions when working with neodymium magnets
Keep away from children

Neodymium magnets are not toys. Eating a few magnets may result in them attracting across intestines, which constitutes a severe health hazard and requires urgent medical intervention.

GPS and phone interference

Remember: neodymium magnets produce a field that disrupts sensitive sensors. Maintain a safe distance from your phone, tablet, and navigation systems.

Safe operation

Handle with care. Neodymium magnets attract from a distance and snap with massive power, often faster than you can react.

Medical interference

Life threat: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.

Allergic reactions

A percentage of the population suffer from a hypersensitivity to Ni, which is the typical protective layer for NdFeB magnets. Prolonged contact might lead to a rash. We recommend use protective gloves.

Heat sensitivity

Avoid heat. NdFeB magnets are sensitive to temperature. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).

Eye protection

NdFeB magnets are sintered ceramics, which means they are fragile like glass. Clashing of two magnets leads to them cracking into small pieces.

Protect data

Very strong magnetic fields can erase data on credit cards, hard drives, and storage devices. Maintain a gap of at least 10 cm.

Fire warning

Fire hazard: Rare earth powder is explosive. Avoid machining magnets without safety gear as this risks ignition.

Crushing risk

Large magnets can crush fingers in a fraction of a second. Never put your hand betwixt two attracting surfaces.

Caution! More info about risks in the article: Magnet Safety Guide.
