Magnetic Field

Other products

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'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.
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.
For people with a pacemaker, we recommend traditional fasteners on a lanyard, clip, or safe pin. For other people, magnets are completely safe and indifferent to health.
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.

Strengths

In addition to their magnetic capacity, neodymium magnets provide the following advantages:
  • They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (in laboratory conditions),
  • They retain their magnetic properties even under close interference source,
  • A magnet with a shiny silver surface looks better,
  • They are known for high magnetic induction at the operating surface, making them more effective,
  • Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures approaching 230°C and above...
  • Thanks to versatility in shaping and the ability to customize to complex applications,
  • Wide application in electronics industry – they find application in magnetic memories, electromotive mechanisms, precision medical tools, also modern systems.
  • Thanks to their power density, small magnets offer high operating force, with minimal size,

Cons

Problematic aspects of neodymium magnets: weaknesses and usage proposals
  • To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
  • NdFeB magnets lose force 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 very resistant to heat
  • Magnets exposed to a humid environment can rust. Therefore during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
  • Limited possibility of creating nuts in the magnet and complex shapes - preferred is cover - magnet mounting.
  • Possible danger to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these products can be problematic in diagnostics medical when they are in the body.
  • With mass production the cost of neodymium magnets can be a barrier,

Pull force analysis

Highest magnetic holding forcewhat affects it?

Information about lifting capacity was defined for the most favorable conditions, assuming:
  • on a block made of mild steel, optimally conducting the magnetic flux
  • possessing a thickness of minimum 10 mm to avoid saturation
  • with an polished touching surface
  • under conditions of no distance (metal-to-metal)
  • under vertical application of breakaway force (90-degree angle)
  • at room temperature

Magnet lifting force in use – key factors

Effective lifting capacity impacted by working environment parameters, such as (from most important):
  • Distance – existence of foreign body (rust, dirt, air) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
  • Load vector – maximum parameter is reached only during perpendicular pulling. The force required to slide of the magnet along the surface is typically many times smaller (approx. 1/5 of the lifting capacity).
  • Steel thickness – insufficiently thick sheet does not close the flux, causing part of the flux to be escaped into the air.
  • Steel type – low-carbon steel gives the best results. Higher carbon content decrease magnetic permeability and lifting capacity.
  • Base smoothness – the more even the plate, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
  • Temperature – temperature increase causes a temporary drop of induction. Check the thermal limit for a given model.

Lifting capacity was assessed using a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet and the plate reduces the load capacity.

H&S for magnets
ICD Warning

Health Alert: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.

Demagnetization risk

Watch the temperature. Exposing the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.

Data carriers

Powerful magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Stay away of at least 10 cm.

Hand protection

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

Eye protection

Despite metallic appearance, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.

Product not for children

Adult use only. Tiny parts pose a choking risk, causing severe trauma. Keep away from children and animals.

Threat to navigation

A powerful magnetic field negatively affects the functioning of magnetometers in smartphones and GPS navigation. Keep magnets close to a smartphone to avoid damaging the sensors.

Conscious usage

Exercise caution. Neodymium magnets act from a long distance and snap with huge force, often quicker than you can react.

Avoid contact if allergic

Nickel alert: The Ni-Cu-Ni coating contains nickel. If redness happens, cease working with magnets and use protective gear.

Dust is flammable

Machining of neodymium magnets carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.

Danger! Details about risks in the article: Safety of working with magnets.
