Frequently asked questions

How much will a magnetic holder hold in practice?
The catalogue value assumes full contact with smooth steel at least 10 mm thick and a perpendicular pull. Thinner sheet, paint, rust and surface irregularities reduce it considerably: on 1 mm sheet about half remains. Lifting and vertical mounting call for an additional safety margin.
Will a holder work on stainless steel?
Not on austenitic grades 304 and 316 — they are effectively non-magnetic. It will not work on aluminium, copper or brass either. Those materials need a mechanical gripper.
Which coating for which conditions?
Nickel-copper-nickel (NiCuNi) is the standard and covers most applications. Epoxy is used for damp environments and outdoor work, zinc is sufficient for dry interiors. Holders in a steel housing or in rubber also protect the magnet against impact.

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 consists of two elements: the magnetic part (back) and the mounting plate (front). The outer part has strong 3M foam tape, to which a business card or plastic case is stuck. The plastic magnet housing is pleasant to the touch, smooth, and safe for the user.
Attraction force is sufficient to hold the badge even on winter clothing. Model UI 45x13x6 [C321] / N38 ensures optimal grip without the risk of losing the badge in motion.
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.

Advantages

Besides their durability, neodymium magnets are valued for these benefits:
  • Their magnetic field remains stable, and after around ten years it decreases only by ~1% (theoretically),
  • They have excellent resistance to magnetism drop due to opposing magnetic fields,
  • By covering with a lustrous layer of nickel, the element acquires an elegant look,
  • Magnetic induction on the surface of the magnet remains impressive,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
  • Thanks to versatility in shaping and the capacity to modify to individual projects,
  • Versatile presence in innovative solutions – they serve a role in mass storage devices, drive modules, medical equipment, and other advanced devices.
  • Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in miniature devices

Disadvantages

Cons of neodymium magnets: application proposals
  • Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, which not only protects them against impacts but also increases their durability
  • NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and 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
  • Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
  • We suggest cover - magnetic holder, due to difficulties in realizing threads inside the magnet and complex shapes.
  • Potential hazard related to microscopic parts of magnets are risky, in case of ingestion, which becomes key in the context of child safety. Additionally, small components of these magnets are able to be problematic in diagnostics medical after entering the body.
  • High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Lifting parameters

Breakaway strength of the magnet in ideal conditions – what it depends on?

Holding force of 1.75 kg is a theoretical maximum value executed under the following configuration:
  • on a base made of mild steel, optimally conducting the magnetic field
  • with a thickness no less than 10 mm
  • with an ideally smooth contact surface
  • with total lack of distance (no coatings)
  • for force applied at a right angle (in the magnet axis)
  • at temperature room level

Lifting capacity in real conditions – factors

In practice, the actual holding force is determined by several key aspects, ranked from crucial:
  • Distance (between the magnet and the metal), as even a very small clearance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to varnish, corrosion or debris).
  • Angle of force application – highest force is available only during pulling at a 90° angle. The shear force of the magnet along the surface is typically several times lower (approx. 1/5 of the lifting capacity).
  • Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
  • Material type – the best choice is high-permeability steel. Hardened steels may attract less.
  • Smoothness – ideal contact is obtained only on polished steel. Rough texture create air cushions, weakening the magnet.
  • Temperature – temperature increase causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.

Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling 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 and the plate lowers the holding force.

Safety rules for work with NdFeB magnets
Metal Allergy

Some people experience a sensitization to nickel, which is the standard coating for neodymium magnets. Extended handling can result in skin redness. We strongly advise wear safety gloves.

Bone fractures

Pinching hazard: The attraction force is so great that it can cause blood blisters, pinching, and broken bones. Use thick gloves.

Magnets are brittle

Despite the nickel coating, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.

Data carriers

Powerful magnetic fields can destroy records on payment cards, hard drives, and storage devices. Keep a distance of min. 10 cm.

Caution required

Before use, read the rules. Sudden snapping can destroy the magnet or injure your hand. Be predictive.

Implant safety

Life threat: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.

Maximum temperature

Watch the temperature. Heating the magnet to high heat will ruin its magnetic structure and pulling force.

Swallowing risk

Absolutely keep magnets away from children. Choking hazard is high, and the consequences of magnets clamping inside the body are tragic.

Impact on smartphones

Navigation devices and smartphones are extremely susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the sensors in your phone.

Combustion hazard

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