Other proposals

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's a standard solution at conferences, trade fairs, and in companies caring about image.
The set consists of two elements: the magnetic part (back) and the mounting plate (front). 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.
Thanks to the use of neodymium, the holder securely grips through a jacket, thick sweater, fleece, or coat. 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. Healthy users can use badges without worrying about their well-being.
We have large warehouse stocks in Poland, allowing for fast fulfillment of orders for companies (even thousands of pieces). Contact us to receive an individual B2B offer tailored to your company's needs.

Advantages as well as disadvantages of rare earth magnets.

Benefits

Apart from their notable magnetism, neodymium magnets have these key benefits:
  • They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (in laboratory conditions),
  • Neodymium magnets are exceptionally resistant to magnetic field loss caused by external field sources,
  • By using a shiny layer of gold, the element gains an modern look,
  • Magnets are distinguished by excellent magnetic induction on the active area,
  • Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures reaching 230°C and above...
  • Possibility of detailed creating and optimizing to concrete conditions,
  • Key role in electronics industry – they are utilized in data components, electromotive mechanisms, diagnostic systems, also other advanced devices.
  • Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,

Cons

Disadvantages of NdFeB magnets:
  • They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
  • Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as 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 stable to moisture, when using outdoors
  • We recommend cover - magnetic mount, due to difficulties in creating nuts inside the magnet and complicated shapes.
  • Possible danger to health – tiny shards of magnets are risky, in case of ingestion, which is particularly important in the context of child safety. Additionally, small components of these magnets can complicate diagnosis medical after entering the body.
  • With mass production the cost of neodymium magnets is economically unviable,

Pull force analysis

Best holding force of the magnet in ideal parameterswhat affects it?

Information about lifting capacity was determined for optimal configuration, including:
  • using a base made of low-carbon steel, serving as a magnetic yoke
  • with a thickness minimum 10 mm
  • with an ideally smooth contact surface
  • without the slightest air gap between the magnet and steel
  • for force applied at a right angle (in the magnet axis)
  • in stable room temperature

Lifting capacity in real conditions – factors

Holding efficiency is influenced by specific conditions, such as (from most important):
  • Distance (between the magnet and the plate), because even a very small distance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
  • Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
  • Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
  • Plate material – mild steel gives the best results. Alloy admixtures lower magnetic properties and lifting capacity.
  • Smoothness – full contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
  • Thermal conditions – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).

Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.

Precautions when working with neodymium magnets
Mechanical processing

Combustion risk: Rare earth powder is explosive. Avoid machining magnets in home conditions as this risks ignition.

Magnets are brittle

Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.

Conscious usage

Handle with care. Rare earth magnets attract from a long distance and snap with huge force, often quicker than you can react.

Keep away from electronics

A powerful magnetic field disrupts the operation of compasses in smartphones and GPS navigation. Keep magnets close to a smartphone to prevent breaking the sensors.

Allergy Warning

Nickel alert: The Ni-Cu-Ni coating contains nickel. If an allergic reaction happens, cease working with magnets and wear gloves.

This is not a toy

Absolutely store magnets out of reach of children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are tragic.

Thermal limits

Regular neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. This process is irreversible.

Keep away from computers

Very strong magnetic fields can destroy records on payment cards, hard drives, and storage devices. Stay away of min. 10 cm.

Warning for heart patients

Warning for patients: Powerful magnets disrupt medical devices. Keep at least 30 cm distance or request help to handle the magnets.

Bone fractures

Watch your fingers. Two large magnets will join instantly with a force of massive weight, crushing everything in their path. Be careful!
