Frequently asked questions

Which rod should I choose for fine contamination?
For particles below 0.5 mm — a Ø32 mm rod in grade N52, with surface induction of about 10,000 Gs. A Ø25 rod in grade N42 gives about 6,500 Gs and is chosen for contamination above 1 mm: bolts, washers, pieces of wire.
Which rod pitch should I choose?
The narrow pitch, 40 mm centre to centre, for fine free-flowing fractions — it gives denser coverage of the cross-section. The wide pitch, 50 mm, for granulates and for damp, greasy or sticky materials, where a narrow pitch risks the material bridging above the rods.
Why does efficiency drop after a few weeks of operation?
Almost always because the separator has not been cleaned. The layer of captured particles shields the field, and further particles settle on that layer rather than on the rod surface, where the gradient is far stronger. The magnets themselves do not weaken at that rate.

The magnetic lifter works based on powerful neodymium magnets and does not require any external power supply. Switching the magnet on and off is done using a simple lever equipped with a safety lock. The load will not fall automatically, which is crucial in heavy sheet transport.
Catalog parameters refer to optimal conditions (thick steel plate, no rust or paint). Thin sheet, rust, scale, or a thick layer of paint drastically lower real lifting capacity. When selecting a lifter, familiarize yourself with the capacity chart (thickness table) and maintain a safety margin.
Thanks to the specially profiled V-type foot, safe lifting of pipes, shafts, and rods is possible. The prism allows the magnet to adjust to the round shape, centering the load. However, remember that capacity for round elements is usually 50% lower than for flat ones (check specification).
Our lifters have a high safety factor of 3:1 or 3.5:1 (depending on model). It gives a large safety margin in case of unforeseen dynamic forces or vibrations. Products have a CE declaration of conformity and meet European machine safety standards.
The key to long life is caring for the working surface (magnetic foot). Any dents or stuck filings increase the air gap and weaken capacity. We recommend periodic technical inspections (minimum once a year) at an authorized service center.

Strengths and weaknesses of neodymium magnets.

Benefits

Besides their exceptional strength, neodymium magnets offer the following advantages:
  • They do not lose power, even over nearly 10 years – the drop in lifting capacity is only ~1% (according to tests),
  • Neodymium magnets remain exceptionally resistant to magnetic field loss caused by external interference,
  • In other words, due to the reflective finish of gold, the element looks attractive,
  • Magnets exhibit very high magnetic induction on the outer side,
  • Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • Thanks to freedom in constructing and the ability to adapt to specific needs,
  • Key role in high-tech industry – they serve a role in computer drives, drive modules, precision medical tools, as well as technologically advanced constructions.
  • Thanks to their power density, small magnets offer high operating force, with minimal size,

Weaknesses

Drawbacks and weaknesses of neodymium magnets and proposals for their use:
  • They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
  • When exposed to high temperature, neodymium magnets suffer a drop in power. 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
  • 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 casing - magnetic mechanism, due to difficulties in creating threads inside the magnet and complex shapes.
  • Health risk related to microscopic parts of magnets pose a threat, if swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that tiny parts of these magnets can be problematic in diagnostics medical after entering the body.
  • High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities

Holding force characteristics

Best holding force of the magnet in ideal parameters – what it depends on?

The lifting capacity listed is a result of laboratory testing performed under standard conditions:
  • with the use of a yoke made of special test steel, ensuring full magnetic saturation
  • possessing a thickness of min. 10 mm to ensure full flux closure
  • with an ideally smooth contact surface
  • with direct contact (without paint)
  • for force applied at a right angle (pull-off, not shear)
  • at standard ambient temperature

Magnet lifting force in use – key factors

In real-world applications, the actual holding force is determined by a number of factors, ranked from the most important:
  • Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
  • Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
  • Plate thickness – too thin sheet does not close the flux, causing part of the power to be lost to the other side.
  • Plate material – mild steel attracts best. Alloy admixtures decrease magnetic properties and holding force.
  • Surface condition – ground elements guarantee perfect abutment, which improves field saturation. Uneven metal reduce efficiency.
  • Temperature – temperature increase causes a temporary drop of force. It is worth remembering the thermal limit for a given model.

Lifting capacity was determined using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, in contrast under shearing force the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate decreases the holding force.

Safe handling of neodymium magnets
Data carriers

Data protection: Strong magnets can ruin data carriers and delicate electronics (pacemakers, medical aids, mechanical watches).

Choking Hazard

These products are not suitable for play. Swallowing multiple magnets can lead to them pinching intestinal walls, which poses a critical condition and necessitates immediate surgery.

Life threat

People with a pacemaker have to keep an absolute distance from magnets. The magnetic field can stop the operation of the life-saving device.

Material brittleness

Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.

Fire warning

Drilling and cutting of NdFeB material carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Keep away from electronics

A strong magnetic field interferes with the functioning of magnetometers in phones and navigation systems. Do not bring magnets near a device to prevent breaking the sensors.

Allergic reactions

It is widely known that the nickel plating (standard magnet coating) is a common allergen. For allergy sufferers, prevent touching magnets with bare hands or opt for versions in plastic housing.

Immense force

Exercise caution. Rare earth magnets attract from a distance and snap with massive power, often faster than you can move away.

Bodily injuries

Big blocks can smash fingers instantly. Never place your hand betwixt two attracting surfaces.

Operating temperature

Keep cool. Neodymium magnets are susceptible to heat. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).
