Frequently asked questions

What badge size fits these holders - will a standard 86x54 mm card work?
Yes, a standard credit-card-size badge of 86x54 mm fits without any issue - this is the most common format for staff and conference badges. The real limit is the steel plate itself: the badge should not be larger than the plate, otherwise the corners overhang and the 3M tape loses grip faster at the edges. Smaller name tags and cards work just as well as long as they fit within the plate's outline. The card format is up to the customer - we only supply the magnetic clasp that attaches to the back of the badge.
We already have lanyard or pin badges. Can they be converted to magnetic ones?
Yes, and this is the most common way our clasps get used - there is no need to order new badges. The clip or pin is removed from the existing badge, and the steel plate that comes with the clasp is stuck on in its place using the included 3M tape. The only condition is a flat, clean back surface for the tape to bond to. PVC cards, plastic inserts and laminated name tags all work without any extra preparation, and converting one badge takes just a moment.
What should a staff badge show, and does it have to carry a surname?
The scope of information on a staff badge is decided by the employer, not by any fixed template - many companies print only a first name and job title, leaving out the surname to limit the personal data visible to customers. This is a data protection decision, so it is worth checking with whoever handles data compliance in the company rather than following a generic pattern. We have no influence on the badge content and do not print it ourselves - we only supply the magnetic clasp that holds the finished badge on clothing.
Can the badge be swapped, for example on a change of role or for a conference?
Yes, the steel plate stays glued to the badge permanently, but the magnetic strip detaches from it at any time - it simply unclips from the plate. When a role or surname changes, the simplest approach is to print a new badge and stick a new plate to it, reusing the same magnetic strip. For one-off events like conferences or training sessions, the same set of clasps can be reused with different badges each time - the plates are inexpensive and are ordered separately from the magnetic strip.
Will the badge rotate, and is it readable from a distance at a counter or reception?
Two-point models such as C321 or C323 hold a badge steadier than a single magnet, since the card rests on two axes and does not spin freely with faster movement. Readability at a distance, however, depends mainly on the badge design itself - font size and contrast - rather than on the clasp, so it is worth using larger print for badges meant to be read at a reception desk or counter. The clasp's job is simply to keep the card from falling and hold it straight on the clothing.
Pacemaker, hearing aid, contactless card - what about safety when wearing the badge?
People with a pacemaker or any other implanted electronic device should not wear a magnetic badge clasp on the chest - this is a rule that cannot be worked around with a different housing or a weaker magnet, and such a person should be given a lanyard or pin badge instead. Contactless RFID cards and magnetic stripes on badges can be demagnetised by prolonged direct contact with a magnet, so it is best not to store them in the same pocket as the clasp. Hearing aids worn close to the chest are worth checking individually with the device manufacturer.
We are ordering badges for a whole team. How many holders to count and what to order with them?
The number of clasps should match the number of people on the team, plus a small spare stock in case a plate is lost or damaged - the badges themselves (cards, name tags, printing) are ordered separately, outside our offer, since we only supply the mounting mechanism. Each clasp already comes with a steel plate and 3M tape, so there is no need to order that separately. It is worth standardising on one model across the team - larger badges or heavier holders work better with a two-magnet version, while light name tags are fine with a single mounting point.

Unlike safety pins or pins, magnetic fastening leaves no marks or holes on the material. Thanks to this, the badge looks professional, straight, and aesthetic all day long. 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. 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. The magnetic field is point-based, short-range, and does not negatively affect a healthy person's body.
We have large warehouse stocks in Poland, allowing for fast fulfillment of orders for companies (even thousands of pieces). You can order samples to check the quality before a larger purchase.

Pros and cons of neodymium magnets.

Pros

In addition to their pulling strength, neodymium magnets provide the following advantages:
  • They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
  • Magnets very well defend themselves against demagnetization caused by external fields,
  • Thanks to the shiny finish, the coating of Ni-Cu-Ni, gold-plated, or silver gives an visually attractive appearance,
  • Magnets have impressive magnetic induction on the surface,
  • Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
  • In view of the option of precise forming and customization to custom projects, NdFeB magnets can be modeled in a broad palette of forms and dimensions, which expands the range of possible applications,
  • Huge importance in advanced technology sectors – they are commonly used in computer drives, electric drive systems, medical equipment, also complex engineering applications.
  • Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Disadvantages

What to avoid - cons of neodymium magnets: tips and applications.
  • Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a special holder, which not only secures them against impacts but also raises their durability
  • Do not exceed this material temperature limit: 80°C. Overheating may permanently weaken the magnet.
  • They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
  • Limited ability of producing nuts in the magnet and complicated forms - preferred is casing - magnetic holder.
  • Possible danger related to microscopic parts of magnets can be dangerous, if swallowed, which gains importance in the context of child health protection. Furthermore, small elements of these magnets can complicate diagnosis medical when they are in the body.
  • With large orders the cost of neodymium magnets is economically unviable,

Holding force characteristics

Maximum lifting capacity of the magnet – what affects it?

The load parameter shown concerns the maximum value, recorded under laboratory conditions, namely:
  • using a sheet made of mild steel, acting as a ideal flux conductor
  • possessing a thickness of at least 10 mm to avoid saturation
  • characterized by lack of roughness
  • without any clearance between the magnet and steel
  • under vertical application of breakaway force (90-degree angle)
  • in temp. approx. 20°C

Practical lifting capacity: influencing factors

Holding efficiency impacted by specific conditions, mainly (from priority):
  • Distance – the presence of foreign body (rust, tape, air) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
  • Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
  • Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
  • Steel type – low-carbon steel attracts best. Higher carbon content decrease magnetic permeability and lifting capacity.
  • Surface condition – ground elements ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
  • Temperature – heating the magnet results in weakening of induction. Check the thermal limit for a given model.

Lifting capacity was assessed using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as fivefold. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.

Safe handling of NdFeB magnets
Pacemakers

For implant holders: Powerful magnets affect electronics. Maintain minimum 30 cm distance or request help to handle the magnets.

Protect data

Equipment safety: Strong magnets can damage data carriers and sensitive devices (heart implants, hearing aids, timepieces).

Handling rules

Handle with care. Neodymium magnets attract from a distance and snap with massive power, often faster than you can react.

Fire warning

Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this may cause fire.

Crushing risk

Mind your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!

Allergy Warning

Certain individuals have a hypersensitivity to Ni, which is the common plating for neodymium magnets. Extended handling might lead to a rash. We strongly advise use safety gloves.

Threat to navigation

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

Material brittleness

Despite metallic appearance, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.

Choking Hazard

Adult use only. Tiny parts pose a choking risk, causing intestinal necrosis. Store away from children and animals.

Heat sensitivity

Do not exceed the maximum operating temperature stated in the specifications of the particular product. The limit depends on the material, geometry and operating arrangement; there is no single threshold for all neodymium magnets. Overheating can permanently weaken a magnet.
