The main and most important advantage is that the magnet does not puncture or damage clothing. Thanks to this, the badge looks professional, straight, and aesthetic all day long. It's a standard solution at conferences, trade fairs, and in companies caring about image.
The set includes a strip with magnets (put under clothes) and a steel plate with tape (on the outside). 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.
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.
People with a pacemaker or other implanted medical devices should not wear magnets near the chest area. Healthy users can use badges without worrying about their well-being.
Yes, we are a direct importer and fulfill large wholesale orders. We offer discount thresholds and quantity discounts depending on order size.

Advantages and disadvantages of Nd2Fe14B magnets.

Benefits

Besides their magnetic performance, neodymium magnets are valued for these benefits:
  • They have constant strength, and over around 10 years their attraction force decreases symbolically – ~1% (in testing),
  • Magnets effectively defend themselves against demagnetization caused by foreign field sources,
  • Thanks to the glossy finish, the layer of Ni-Cu-Ni, gold-plated, or silver gives an professional appearance,
  • Magnets exhibit huge magnetic induction on the outer side,
  • Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling action at temperatures reaching 230°C and above...
  • Considering the potential of free shaping and adaptation to individualized needs, magnetic components can be modeled in a wide range of shapes and sizes, which increases their versatility,
  • Universal use in future technologies – they are used in data components, electric drive systems, medical devices, as well as multitasking production systems.
  • Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Weaknesses

Problematic aspects of neodymium magnets: weaknesses and usage proposals
  • To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
  • NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (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
  • Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
  • Due to limitations in realizing threads and complicated shapes in magnets, we recommend using a housing - magnetic mount.
  • Possible danger related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child health protection. Additionally, tiny parts of these devices are able to complicate diagnosis medical after entering the body.
  • Due to neodymium price, their price is relatively high,

Holding force characteristics

Maximum magnetic pulling force – what contributes to it?

Information about lifting capacity is the result of a measurement for optimal configuration, including:
  • with the use of a sheet made of low-carbon steel, ensuring maximum field concentration
  • possessing a thickness of minimum 10 mm to avoid saturation
  • with an ground touching surface
  • under conditions of no distance (metal-to-metal)
  • for force acting at a right angle (in the magnet axis)
  • at temperature room level

Determinants of practical lifting force of a magnet

Bear in mind that the magnet holding may be lower influenced by elements below, starting with the most relevant:
  • Clearance – existence of foreign body (rust, tape, air) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
  • Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet holds much less (typically approx. 20-30% of maximum force).
  • Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
  • Steel type – low-carbon steel attracts best. Alloy steels lower magnetic properties and holding force.
  • Plate texture – ground elements ensure maximum contact, which increases force. Rough surfaces weaken the grip.
  • Temperature influence – high temperature weakens magnetic field. Too high temperature can permanently demagnetize the magnet.

Lifting capacity testing was carried out on a smooth plate of optimal thickness, under perpendicular forces, in contrast under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate decreases the lifting capacity.

Warnings
Implant safety

Medical warning: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.

Keep away from computers

Powerful magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Stay away of at least 10 cm.

Fire risk

Fire hazard: Rare earth powder is explosive. Do not process magnets without safety gear as this risks ignition.

Material brittleness

Beware of splinters. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.

GPS Danger

A powerful magnetic field interferes with the functioning of compasses in smartphones and GPS navigation. Keep magnets near a smartphone to prevent breaking the sensors.

Crushing risk

Danger of trauma: The pulling power is so immense that it can cause hematomas, crushing, and broken bones. Use thick gloves.

Heat warning

Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will permanently weaken its properties and strength.

Allergic reactions

It is widely known that the nickel plating (standard magnet coating) is a common allergen. For allergy sufferers, avoid direct skin contact or select encased magnets.

Handling guide

Exercise caution. Rare earth magnets attract from a distance and snap with huge force, often quicker than you can react.

Product not for children

Neodymium magnets are not suitable for play. Eating a few magnets can lead to them pinching intestinal walls, which constitutes a direct threat to life and requires urgent medical intervention.
