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.

Pros as well as cons of rare earth magnets.

Strengths

In addition to their magnetic capacity, neodymium magnets provide the following advantages:
  • They do not lose magnetism, even over approximately ten years – the decrease in strength is only ~1% (based on measurements),
  • They show high resistance to demagnetization induced by external magnetic fields,
  • The use of an refined finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
  • They are known for high magnetic induction at the operating surface, which increases their power,
  • Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures reaching 230°C and above...
  • Possibility of precise creating as well as optimizing to complex requirements,
  • Universal use in modern technologies – they find application in mass storage devices, electromotive mechanisms, diagnostic systems, as well as modern systems.
  • Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which allows their use in small systems

Limitations

Cons of neodymium magnets: application proposals
  • Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only protects them against impacts but also increases their durability
  • When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
  • Due to limitations in producing threads and complex shapes in magnets, we recommend using a housing - magnetic mechanism.
  • Potential hazard to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child safety. It is also worth noting that tiny parts of these products are able to be problematic in diagnostics medical when they are in the body.
  • Due to complex production process, their price exceeds standard values,

Pull force analysis

Detachment force of the magnet in optimal conditions – what it depends on?

The lifting capacity listed is a theoretical maximum value performed under standard conditions:
  • with the use of a yoke made of low-carbon steel, ensuring full magnetic saturation
  • whose thickness equals approx. 10 mm
  • with an ground contact surface
  • under conditions of gap-free contact (metal-to-metal)
  • under vertical force direction (90-degree angle)
  • at standard ambient temperature

Lifting capacity in real conditions – factors

Bear in mind that the working load may be lower subject to the following factors, in order of importance:
  • Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
  • Force direction – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of maximum force).
  • Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
  • Chemical composition of the base – mild steel attracts best. Higher carbon content reduce magnetic properties and holding force.
  • Base smoothness – the more even the plate, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
  • Operating temperature – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).

Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate reduces the lifting capacity.

Safety rules for work with neodymium magnets
Danger to the youngest

Only for adults. Tiny parts can be swallowed, causing serious injuries. Store away from kids and pets.

Nickel coating and allergies

Nickel alert: The nickel-copper-nickel coating contains nickel. If an allergic reaction occurs, cease handling magnets and use protective gear.

Dust is flammable

Combustion risk: Neodymium dust is explosive. Avoid machining magnets in home conditions as this risks ignition.

Precision electronics

Remember: rare earth magnets produce a field that interferes with precision electronics. Keep a safe distance from your mobile, device, and navigation systems.

Handling rules

Exercise caution. Neodymium magnets attract from a distance and connect with huge force, often quicker than you can react.

Crushing risk

Watch your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!

Implant safety

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

Permanent damage

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

Risk of cracking

Despite the nickel coating, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.

Electronic hazard

Do not bring magnets close to a purse, laptop, or TV. The magnetic field can permanently damage these devices and wipe information from cards.
