Unlike safety pins or pins, magnetic fastening leaves no marks or holes on the material. This ensures elegance and wearing comfort, without the risk of pricking yourself or ruining clothes. 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). 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.
Yes, the neodymium magnets used are very strong and hold even through thick materials. We offer versions with two or three magnets, which further increases stability and strength.
There is a risk of disrupting pacemaker operation by a strong magnetic field, so we advise against this solution for people with implants. 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. You can order samples to check the quality before a larger purchase.

Advantages and disadvantages of neodymium magnets.

Advantages

Besides their remarkable field intensity, neodymium magnets offer the following advantages:
  • They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
  • They do not lose their magnetic properties even under close interference source,
  • A magnet with a smooth gold surface is more attractive,
  • Magnetic induction on the working layer of the magnet remains maximum,
  • Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • Thanks to the option of free molding and customization to unique solutions, NdFeB magnets can be manufactured in a wide range of shapes and sizes, which increases their versatility,
  • Huge importance in innovative solutions – they are utilized in magnetic memories, motor assemblies, precision medical tools, and modern systems.
  • Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which enables their usage in compact constructions

Weaknesses

What to avoid - cons of neodymium magnets: application proposals
  • At very strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
  • When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
  • Due to limitations in realizing threads and complex forms in magnets, we propose using cover - magnetic mount.
  • Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, tiny parts of these magnets can disrupt the diagnostic process medical in case of swallowing.
  • High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities

Holding force characteristics

Maximum lifting capacity of the magnetwhat affects it?

The load parameter shown concerns the maximum value, measured under ideal test conditions, specifically:
  • on a plate made of structural steel, effectively closing the magnetic flux
  • possessing a massiveness of minimum 10 mm to ensure full flux closure
  • characterized by lack of roughness
  • under conditions of no distance (surface-to-surface)
  • for force acting at a right angle (in the magnet axis)
  • in stable room temperature

Practical aspects of lifting capacity – factors

In real-world applications, the actual lifting capacity depends on a number of factors, listed from most significant:
  • Air gap (betwixt the magnet and the plate), as even a very small distance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to varnish, rust or dirt).
  • Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
  • Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
  • Metal type – not every steel reacts the same. High carbon content weaken the attraction effect.
  • Surface condition – smooth surfaces guarantee perfect abutment, which improves force. Rough surfaces weaken the grip.
  • Thermal factor – high temperature reduces magnetic field. Too high temperature can permanently damage the magnet.

Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Additionally, even a minimal clearance between the magnet and the plate decreases the lifting capacity.

H&S for magnets
Danger to the youngest

NdFeB magnets are not toys. Eating a few magnets may result in them pinching intestinal walls, which poses a direct threat to life and requires immediate surgery.

Dust is flammable

Powder created during grinding of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.

Allergic reactions

Studies show that nickel (standard magnet coating) is a common allergen. If you have an allergy, prevent touching magnets with bare hands and select versions in plastic housing.

Safe distance

Device Safety: Strong magnets can ruin data carriers and sensitive devices (pacemakers, medical aids, mechanical watches).

ICD Warning

For implant holders: Powerful magnets affect electronics. Maintain at least 30 cm distance or request help to work with the magnets.

GPS and phone interference

Be aware: rare earth magnets produce a field that disrupts precision electronics. Maintain a separation from your phone, tablet, and GPS.

Crushing force

Watch your fingers. Two large magnets will join instantly with a force of massive weight, destroying anything in their path. Exercise extreme caution!

Thermal limits

Keep cool. NdFeB magnets are sensitive to heat. If you require operation above 80°C, look for HT versions (H, SH, UH).

Handling rules

Handle magnets consciously. Their immense force can surprise even professionals. Plan your moves and respect their power.

Magnets are brittle

Despite the nickel coating, the material is delicate and not impact-resistant. Do not hit, as the magnet may shatter into hazardous fragments.
