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.
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.
Yes, the neodymium magnets used are very strong and hold even through thick materials. A larger number of magnetic points prevents the badge from twisting.
There is a risk of disrupting pacemaker operation by a strong magnetic field, so we advise against this solution for people with implants. The magnetic field is point-based, short-range, and does not negatively affect a healthy person's body.
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

In addition to their magnetic efficiency, neodymium magnets provide the following advantages:
  • They do not lose power, even over around ten years – the decrease in power is only ~1% (theoretically),
  • Magnets very well defend themselves against loss of magnetization caused by external fields,
  • A magnet with a smooth nickel surface is more attractive,
  • They feature high magnetic induction at the operating surface, which improves attraction properties,
  • Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
  • Possibility of exact shaping and adapting to complex conditions,
  • Universal use in high-tech industry – they find application in data components, electric motors, advanced medical instruments, and multitasking production systems.
  • Compactness – despite small sizes they generate large force, making them ideal for precision applications

Weaknesses

Drawbacks and weaknesses of neodymium magnets and ways of using them
  • At strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
  • Due to limitations in creating nuts and complicated shapes in magnets, we recommend using a housing - magnetic mechanism.
  • Potential hazard to health – tiny shards of magnets are risky, in case of ingestion, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these products are able to disrupt the diagnostic process medical in case of swallowing.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Pull force analysis

Breakaway strength of the magnet in ideal conditions – what affects it?

Holding force of 1.75 kg is a measurement result performed under specific, ideal conditions:
  • on a plate made of mild steel, perfectly concentrating the magnetic field
  • whose transverse dimension is min. 10 mm
  • with a plane cleaned and smooth
  • with direct contact (no coatings)
  • during pulling in a direction vertical to the plane
  • in neutral thermal conditions

Magnet lifting force in use – key factors

In real-world applications, the actual lifting capacity depends on many variables, presented from crucial:
  • Clearance – existence of any layer (paint, tape, air) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
  • Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of nominal force).
  • Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
  • Material type – ideal substrate is high-permeability steel. Cast iron may generate lower lifting capacity.
  • Plate texture – smooth surfaces ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
  • Temperature – heating the magnet results in weakening of induction. It is worth remembering the thermal limit for a given model.

Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, whereas under parallel forces the holding force is lower. Moreover, even a minimal clearance between the magnet and the plate reduces the load capacity.

Warnings
Nickel allergy

Medical facts indicate that the nickel plating (standard magnet coating) is a common allergen. If your skin reacts to metals, prevent touching magnets with bare hands and choose versions in plastic housing.

Shattering risk

Watch out for shards. Magnets can explode upon violent connection, launching shards into the air. We recommend safety glasses.

Combustion hazard

Drilling and cutting of NdFeB material poses a fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Electronic devices

Powerful magnetic fields can erase data on payment cards, HDDs, and storage devices. Stay away of min. 10 cm.

Threat to navigation

Navigation devices and smartphones are extremely susceptible to magnetic fields. Direct contact with a strong magnet can ruin the sensors in your phone.

Choking Hazard

Only for adults. Tiny parts can be swallowed, causing severe trauma. Keep out of reach of kids and pets.

Caution required

Handle with care. Rare earth magnets act from a distance and connect with massive power, often quicker than you can move away.

Crushing force

Pinching hazard: The attraction force is so great that it can result in hematomas, crushing, and broken bones. Use thick gloves.

Heat warning

Control the heat. Exposing the magnet to high heat will destroy its magnetic structure and pulling force.

Medical interference

People with a ICD should keep an safe separation from magnets. The magnetism can interfere with the operation of the implant.
