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 and cons of Nd2Fe14B magnets.

Advantages

In addition to their pulling strength, neodymium magnets provide the following advantages:
  • They do not lose strength, even after nearly ten years – the reduction in power is only ~1% (theoretically),
  • They are extremely resistant to demagnetization induced by external field influence,
  • The use of an metallic layer of noble metals (nickel, gold, silver) causes the element to look better,
  • Neodymium magnets ensure maximum magnetic induction on a small surface, which increases force concentration,
  • Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
  • Thanks to modularity in shaping and the ability to modify to complex applications,
  • Wide application in future technologies – they are used in data components, motor assemblies, diagnostic systems, as well as technologically advanced constructions.
  • Thanks to their power density, small magnets offer high operating force, in miniature format,

Weaknesses

Disadvantages of NdFeB magnets:
  • To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
  • When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • Magnets exposed to a humid environment can rust. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
  • Limited possibility of making nuts in the magnet and complex forms - preferred is cover - mounting mechanism.
  • Possible danger to health – tiny shards of magnets are risky, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small components of these magnets are able to be problematic in diagnostics medical when they are in the body.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Magnetic strength at its maximum – what contributes to it?

Information about lifting capacity is the result of a measurement for the most favorable conditions, including:
  • using a sheet made of high-permeability steel, serving as a ideal flux conductor
  • with a thickness minimum 10 mm
  • with an ground contact surface
  • under conditions of gap-free contact (metal-to-metal)
  • under axial application of breakaway force (90-degree angle)
  • at room temperature

Determinants of lifting force in real conditions

In real-world applications, the actual holding force results from several key aspects, ranked from the most important:
  • 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 detachment vertically. When attempting to slide, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
  • Base massiveness – insufficiently thick plate does not accept the full field, causing part of the flux to be lost to the other side.
  • Chemical composition of the base – low-carbon steel attracts best. Alloy admixtures lower magnetic permeability and holding force.
  • Base smoothness – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
  • Thermal conditions – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, in contrast under shearing force the holding force is lower. Moreover, even a minimal clearance between the magnet and the plate decreases the lifting capacity.

Safe handling of NdFeB magnets
GPS Danger

Be aware: rare earth magnets generate a field that disrupts sensitive sensors. Keep a safe distance from your mobile, device, and navigation systems.

Demagnetization risk

Control the heat. Exposing the magnet above 80 degrees Celsius will permanently weaken its properties and pulling force.

Serious injuries

Risk of injury: The pulling power is so immense that it can cause hematomas, crushing, and broken bones. Use thick gloves.

Allergy Warning

Allergy Notice: The nickel-copper-nickel coating contains nickel. If an allergic reaction appears, immediately stop handling magnets and use protective gear.

No play value

Only for adults. Tiny parts can be swallowed, causing severe trauma. Keep away from children and animals.

Do not drill into magnets

Fire warning: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this risks ignition.

Implant safety

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

Powerful field

Use magnets consciously. Their immense force can shock even experienced users. Plan your moves and respect their force.

Beware of splinters

Despite the nickel coating, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.

Protect data

Do not bring magnets near a purse, laptop, or screen. The magnetism can permanently damage these devices and wipe information from cards.
