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. Thanks to branded foam tape, badge mounting is instant, durable, and sure. 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. Model UI 40x12x7 [CA] ensures optimal grip without the risk of losing the badge in motion.
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.
We serve advertising agencies, printing houses, hotels, and corporations, offering attractive prices for bulk purchases. We offer discount thresholds and quantity discounts depending on order size.

Strengths and weaknesses of rare earth magnets.

Benefits

Besides their remarkable pulling force, neodymium magnets offer the following advantages:
  • They do not lose magnetism, even during around ten years – the decrease in strength is only ~1% (theoretically),
  • Neodymium magnets are characterized by extremely resistant to magnetic field loss caused by external magnetic fields,
  • In other words, due to the aesthetic layer of gold, the element gains visual value,
  • They show high magnetic induction at the operating surface, making them more effective,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
  • In view of the potential of accurate shaping and customization to unique projects, magnetic components can be manufactured in a broad palette of shapes and sizes, which increases their versatility,
  • Huge importance in innovative solutions – they find application in computer drives, motor assemblies, medical equipment, also industrial machines.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Cons

Disadvantages of neodymium magnets:
  • To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
  • Neodymium magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
  • Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
  • Due to limitations in realizing threads and complicated shapes in magnets, we propose using a housing - magnetic mount.
  • Possible danger related to microscopic parts of magnets are risky, in case of ingestion, which is particularly important in the context of child safety. It is also worth noting that small elements of these products are able to complicate diagnosis medical in case of swallowing.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Optimal lifting capacity of a neodymium magnet – what affects it?

The load parameter shown refers to the peak performance, recorded under laboratory conditions, meaning:
  • with the use of a sheet made of low-carbon steel, guaranteeing maximum field concentration
  • possessing a thickness of minimum 10 mm to ensure full flux closure
  • with a plane free of scratches
  • without any insulating layer between the magnet and steel
  • under vertical force direction (90-degree angle)
  • in temp. approx. 20°C

Magnet lifting force in use – key factors

It is worth knowing that the magnet holding may be lower depending on the following factors, in order of importance:
  • Distance – existence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
  • Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
  • Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
  • Steel grade – the best choice is pure iron steel. Stainless steels may attract less.
  • Surface condition – smooth surfaces ensure maximum contact, which increases field saturation. Uneven metal weaken the grip.
  • Temperature influence – hot environment reduces pulling force. Too high temperature can permanently damage the magnet.

Lifting capacity was assessed by applying a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under shearing force the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate decreases the load capacity.

Safe handling of NdFeB magnets
Medical implants

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

Do not underestimate power

Handle with care. Neodymium magnets act from a distance and snap with huge force, often quicker than you can react.

Heat sensitivity

Do not overheat. Neodymium magnets are sensitive to temperature. If you need resistance above 80°C, look for special high-temperature series (H, SH, UH).

Combustion hazard

Drilling and cutting of neodymium magnets poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.

Physical harm

Large magnets can break fingers in a fraction of a second. Under no circumstances put your hand between two strong magnets.

Swallowing risk

Only for adults. Small elements pose a choking risk, causing intestinal necrosis. Store out of reach of children and animals.

Nickel coating and allergies

Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction appears, immediately stop handling magnets and wear gloves.

Precision electronics

A powerful magnetic field negatively affects the functioning of magnetometers in smartphones and GPS navigation. Maintain magnets near a device to prevent damaging the sensors.

Protect data

Equipment safety: Strong magnets can ruin data carriers and delicate electronics (pacemakers, hearing aids, mechanical watches).

Magnet fragility

Neodymium magnets are sintered ceramics, meaning they are prone to chipping. Impact of two magnets leads to them cracking into small pieces.
