The magnetic holder is safe for delicate fabrics, expensive suits, silk, and shirts. 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.
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. For other people, magnets are completely safe and indifferent to health.
We have large warehouse stocks in Poland, allowing for fast fulfillment of orders for companies (even thousands of pieces). We offer discount thresholds and quantity discounts depending on order size.

Pros and cons of rare earth magnets.

Advantages

In addition to their pulling strength, neodymium magnets provide the following advantages:
  • They retain magnetic properties for nearly 10 years – the drop is just ~1% (according to analyses),
  • They are extremely resistant to demagnetization induced by external magnetic fields,
  • Thanks to the reflective finish, the plating of nickel, gold-plated, or silver-plated gives an clean appearance,
  • Neodymium magnets deliver maximum magnetic induction on a contact point, which ensures high operational effectiveness,
  • Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures approaching 230°C and above...
  • Thanks to versatility in shaping and the ability to adapt to specific needs,
  • Fundamental importance in advanced technology sectors – they are used in computer drives, electric motors, medical devices, and technologically advanced constructions.
  • Thanks to their power density, small magnets offer high operating force, occupying minimum space,

Limitations

Problematic aspects of neodymium magnets and ways of using them
  • To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
  • We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
  • Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
  • Due to limitations in creating threads and complicated forms in magnets, we propose using casing - magnetic mount.
  • Possible danger related to microscopic parts of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child safety. It is also worth noting that small elements of these devices are able to complicate diagnosis medical in case of swallowing.
  • Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Pull force analysis

Maximum holding power of the magnet – what contributes to it?

Breakaway force was determined for ideal contact conditions, including:
  • using a plate made of low-carbon steel, functioning as a circuit closing element
  • whose thickness reaches at least 10 mm
  • characterized by even structure
  • under conditions of gap-free contact (metal-to-metal)
  • during pulling in a direction perpendicular to the plane
  • in temp. approx. 20°C

Practical lifting capacity: influencing factors

It is worth knowing that the magnet holding may be lower influenced by the following factors, in order of importance:
  • Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
  • Direction of force – highest force is obtained only during perpendicular pulling. The shear force of the magnet along the plate is usually many times smaller (approx. 1/5 of the lifting capacity).
  • Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
  • Steel grade – ideal substrate is high-permeability steel. Hardened steels may have worse magnetic properties.
  • Plate texture – smooth surfaces guarantee perfect abutment, which improves force. Uneven metal reduce efficiency.
  • Temperature – temperature increase causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity was assessed by applying a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, however under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate reduces the holding force.

Safe handling of neodymium magnets
Shattering risk

NdFeB magnets are sintered ceramics, which means they are prone to chipping. Clashing of two magnets will cause them breaking into small pieces.

Cards and drives

Very strong magnetic fields can corrupt files on credit cards, HDDs, and storage devices. Stay away of at least 10 cm.

Do not overheat magnets

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

Life threat

For implant holders: Strong magnetic fields affect electronics. Keep minimum 30 cm distance or ask another person to handle the magnets.

Threat to navigation

GPS units and mobile phones are highly sensitive to magnetism. Close proximity with a powerful NdFeB magnet can decalibrate the internal compass in your phone.

No play value

Strictly keep magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are life-threatening.

Metal Allergy

It is widely known that nickel (standard magnet coating) is a potent allergen. If your skin reacts to metals, prevent direct skin contact and choose encased magnets.

Do not underestimate power

Handle with care. Rare earth magnets attract from a long distance and snap with huge force, often faster than you can react.

Bone fractures

Danger of trauma: The attraction force is so great that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.

Mechanical processing

Fire hazard: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
