The main and most important advantage is that the magnet does not puncture or damage clothing. 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. The outer part has strong 3M foam tape, to which a business card or plastic case is stuck. 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.
There is a risk of disrupting pacemaker operation by a strong magnetic field, so we advise against this solution for people with implants. Healthy users can use badges without worrying about their well-being.
We serve advertising agencies, printing houses, hotels, and corporations, offering attractive prices for bulk purchases. You can order samples to check the quality before a larger purchase.

Pros as well as cons of Nd2Fe14B magnets.

Benefits

Apart from their notable magnetic energy, neodymium magnets have these key benefits:
  • They do not lose magnetism, even after approximately 10 years – the reduction in strength is only ~1% (theoretically),
  • They do not lose their magnetic properties even under strong external field,
  • Thanks to the elegant finish, the layer of nickel, gold-plated, or silver gives an clean appearance,
  • Magnetic induction on the working part of the magnet is maximum,
  • Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • Possibility of exact shaping and adapting to concrete conditions,
  • Versatile presence in modern industrial fields – they are commonly used in hard drives, electric motors, medical equipment, also modern systems.
  • Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which allows their use in compact constructions

Disadvantages

Problematic aspects of neodymium magnets and ways of using them
  • They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also increases its resistance to damage
  • NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as 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 rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
  • We recommend casing - magnetic holder, due to difficulties in realizing nuts inside the magnet and complicated forms.
  • Potential hazard resulting from small fragments of magnets are risky, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, tiny parts of these devices can complicate diagnosis medical when they are in the body.
  • Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Lifting parameters

Best holding force of the magnet in ideal parameters – what it depends on?

The load parameter shown concerns the peak performance, obtained under ideal test conditions, specifically:
  • with the application of a sheet made of low-carbon steel, guaranteeing maximum field concentration
  • whose transverse dimension equals approx. 10 mm
  • characterized by lack of roughness
  • under conditions of ideal adhesion (surface-to-surface)
  • under axial application of breakaway force (90-degree angle)
  • at ambient temperature approx. 20 degrees Celsius

Impact of factors on magnetic holding capacity in practice

Effective lifting capacity is influenced by working environment parameters, including (from most important):
  • 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.
  • Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
  • Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
  • Material composition – not every steel attracts identically. Alloy additives worsen the interaction with the magnet.
  • Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
  • Operating temperature – 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 testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, however under parallel forces the holding force is lower. In addition, even a minimal clearance between the magnet and the plate reduces the holding force.

Precautions when working with neodymium magnets
Shattering risk

Protect your eyes. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. We recommend safety glasses.

Hand protection

Danger of trauma: The pulling power is so great that it can result in blood blisters, crushing, and broken bones. Protective gloves are recommended.

Compass and GPS

A strong magnetic field negatively affects the functioning of magnetometers in smartphones and GPS navigation. Do not bring magnets near a smartphone to avoid breaking the sensors.

This is not a toy

Product intended for adults. Tiny parts pose a choking risk, leading to intestinal necrosis. Keep away from kids and pets.

Machining danger

Fire hazard: Neodymium dust is explosive. Avoid machining magnets without safety gear as this may cause fire.

Keep away from computers

Powerful magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Maintain a gap of min. 10 cm.

Immense force

Use magnets consciously. Their powerful strength can shock even professionals. Stay alert and respect their power.

Life threat

Patients with a ICD have to maintain an large gap from magnets. The magnetism can stop the functioning of the life-saving device.

Demagnetization risk

Do not overheat. NdFeB magnets are susceptible to temperature. If you need resistance above 80°C, look for HT versions (H, SH, UH).

Nickel allergy

Certain individuals suffer from a contact allergy to nickel, which is the standard coating for neodymium magnets. Extended handling can result in dermatitis. It is best to use safety gloves.
