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.

Thanks to two poles on one plane, this holder holds much stronger than a regular block magnet of the same size. They are characterized by high capacity and resistance to mechanical impacts.
Two mounting points (in larger models) prevent the holder from rotating and ensure a solid connection. They can be screwed to wood, walls, aluminum profiles, furniture boards, or plastics.
Thanks to the short-circuiting of the magnetic field by steel side walls, holding force is concentrated and very large. These are some of the strongest solutions for flat mounting available on the market.
The construction is mechanically very robust, allowing use in difficult workshop and industrial conditions. They are ideal for heavy doors, machine flaps, molds, and fastening systems in industry.
Magnets inside are nickel-plated, and the trough has an anti-corrosion layer. In dry rooms, holders are practically indestructible.

Advantages as well as disadvantages of neodymium magnets.

Strengths

Besides their remarkable pulling force, neodymium magnets offer the following advantages:
  • They do not lose magnetism, even after approximately ten years – the drop in lifting capacity is only ~1% (based on measurements),
  • They have excellent resistance to weakening of magnetic properties when exposed to external fields,
  • By covering with a reflective coating of nickel, the element gains an elegant look,
  • Magnets possess huge magnetic induction on the working surface,
  • 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...
  • Considering the ability of flexible molding and adaptation to individualized needs, neodymium magnets can be manufactured in a variety of geometric configurations, which amplifies use scope,
  • Key role in innovative solutions – they are used in data components, electromotive mechanisms, advanced medical instruments, also technologically advanced constructions.
  • Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in miniature devices

Weaknesses

Disadvantages of neodymium magnets:
  • To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
  • We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 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.
  • We recommend cover - magnetic mechanism, due to difficulties in producing threads inside the magnet and complicated shapes.
  • Health risk related to microscopic parts of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these products can be problematic in diagnostics medical when they are in the body.
  • 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

Highest magnetic holding force – what affects it?

The force parameter 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 reaches at least 10 mm
  • with an ideally smooth contact surface
  • with zero gap (without paint)
  • during detachment in a direction vertical to the plane
  • at ambient temperature approx. 20 degrees Celsius

What influences lifting capacity in practice

In real-world applications, the actual holding force results from several key aspects, presented from crucial:
  • Distance (between the magnet and the metal), because even a tiny clearance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to paint, corrosion or debris).
  • Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
  • Steel thickness – too thin plate does not close the flux, causing part of the flux to be wasted into the air.
  • Metal type – not every steel reacts the same. High carbon content worsen the interaction with the magnet.
  • Surface condition – ground elements ensure maximum contact, which increases force. Uneven metal weaken the grip.
  • Thermal conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).

Lifting capacity was assessed with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate decreases the load capacity.

Safe handling of neodymium magnets
Dust explosion hazard

Machining of neodymium magnets carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.

This is not a toy

These products are not suitable for play. Swallowing multiple magnets can lead to them connecting inside the digestive tract, which poses a severe health hazard and necessitates immediate surgery.

ICD Warning

For implant holders: Powerful magnets disrupt medical devices. Keep at least 30 cm distance or request help to work with the magnets.

Threat to electronics

Device Safety: Neodymium magnets can damage data carriers and delicate electronics (pacemakers, medical aids, timepieces).

Conscious usage

Before starting, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.

Fragile material

NdFeB magnets are sintered ceramics, which means they are fragile like glass. Collision of two magnets will cause them shattering into shards.

GPS and phone interference

GPS units and mobile phones are extremely susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can ruin the internal compass in your phone.

Skin irritation risks

Allergy Notice: The nickel-copper-nickel coating contains nickel. If skin irritation appears, cease working with magnets and wear gloves.

Permanent damage

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

Hand protection

Big blocks can crush fingers instantly. Do not put your hand betwixt two strong magnets.
