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.

Strengths and weaknesses of rare earth magnets.

Advantages

Besides their durability, neodymium magnets are valued for these benefits:
  • They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (according to literature),
  • They have excellent resistance to weakening of magnetic properties when exposed to external fields,
  • Thanks to the shimmering finish, the plating of Ni-Cu-Ni, gold, or silver gives an visually attractive appearance,
  • Neodymium magnets deliver maximum magnetic induction on a their surface, which ensures high operational effectiveness,
  • Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • Possibility of individual shaping and adjusting to atypical requirements,
  • Significant place in future technologies – they serve a role in magnetic memories, motor assemblies, advanced medical instruments, and industrial machines.
  • Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Disadvantages

Cons of neodymium magnets: tips and applications.
  • At very strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
  • When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their strength 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
  • Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
  • Limited ability of producing nuts in the magnet and complicated forms - recommended is cover - magnet mounting.
  • Health risk to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
  • Due to complex production process, their price exceeds standard values,

Lifting parameters

Maximum lifting capacity of the magnet – what it depends on?

The declared magnet strength represents the peak performance, measured under laboratory conditions, specifically:
  • using a plate made of high-permeability steel, serving as a circuit closing element
  • whose transverse dimension equals approx. 10 mm
  • characterized by smoothness
  • under conditions of gap-free contact (surface-to-surface)
  • during detachment in a direction vertical to the plane
  • at ambient temperature approx. 20 degrees Celsius

Magnet lifting force in use – key factors

Real force impacted by specific conditions, including (from priority):
  • Space between magnet and steel – every millimeter of separation (caused e.g. by varnish or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
  • Loading method – catalog parameter refers to pulling vertically. When slipping, the magnet holds much less (typically approx. 20-30% of maximum force).
  • Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
  • Steel grade – ideal substrate is pure iron steel. Hardened steels may generate lower lifting capacity.
  • Surface finish – ideal contact is possible only on smooth steel. Rough texture create air cushions, weakening the magnet.
  • Operating temperature – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, whereas under attempts to slide the magnet the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.

Safety rules for work with NdFeB magnets
Do not overheat magnets

Watch the temperature. Exposing the magnet to high heat will permanently weaken its magnetic structure and pulling force.

Medical implants

For implant holders: Strong magnetic fields disrupt medical devices. Maintain minimum 30 cm distance or ask another person to handle the magnets.

Phone sensors

A strong magnetic field interferes with the operation of magnetometers in smartphones and GPS navigation. Maintain magnets near a smartphone to prevent damaging the sensors.

This is not a toy

Product intended for adults. Small elements pose a choking risk, causing intestinal necrosis. Keep out of reach of children and animals.

Handling rules

Before use, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Be predictive.

Protect data

Intense magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Keep a distance of min. 10 cm.

Bodily injuries

Watch your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, crushing anything in their path. Be careful!

Dust explosion hazard

Machining of neodymium magnets carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.

Shattering risk

Neodymium magnets are ceramic materials, meaning they are very brittle. Clashing of two magnets leads to them shattering into small pieces.

Avoid contact if allergic

Some people experience a sensitization to Ni, which is the typical protective layer for NdFeB magnets. Extended handling might lead to dermatitis. We strongly advise use protective gloves.
