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.

They serve to create mobile suspension points without the need to drill holes in beams. You can use them to organize wires, hang tools, or clothes on metal racks.
The tip is fully demountable - you can unscrew the hook and screw in a bolt, eyelet, or other element in its place. Thanks to this, one magnet can perform many functions - sometimes be a hook, and sometimes a holder for a bolt.
The nominal capacity (e.g., 38.00 kg) refers to perpendicular (vertical) force when mounted on the ceiling. When mounting on a wall (vertically), the holding force is much lower due to shear force (the magnet may slide).
The steel housing (cup) shields the magnetic field, directing all its power downwards, onto the contact surface. The housing ensures mechanical durability, which is important in industrial and assembly conditions.
In the bathroom or kitchen, they will work perfectly, provided they are not directly splashed with water. Metal elements can rust with constant contact with atmospheric moisture.

Advantages as well as disadvantages of neodymium magnets.

Strengths

In addition to their pulling strength, neodymium magnets provide the following advantages:
  • They have stable power, and over more than 10 years their attraction force decreases symbolically – ~1% (in testing),
  • Neodymium magnets are distinguished by exceptionally resistant to magnetic field loss caused by external interference,
  • By using a decorative coating of silver, the element presents an modern look,
  • The surface of neodymium magnets generates a maximum magnetic field – this is one of their assets,
  • Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
  • In view of the ability of accurate molding and adaptation to specialized requirements, magnetic components can be created in a broad palette of geometric configurations, which makes them more universal,
  • Wide application in high-tech industry – they are used in computer drives, motor assemblies, advanced medical instruments, as well as multitasking production systems.
  • Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which allows their use in small systems

Cons

What to avoid - cons of neodymium magnets: application proposals
  • They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
  • We warn that neodymium magnets can lose their power 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. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
  • Due to limitations in producing nuts and complicated forms in magnets, we recommend using cover - magnetic mechanism.
  • Potential hazard to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child health protection. It is also worth noting that small components of these products are able to be problematic in diagnostics medical after entering the body.
  • With budget limitations the cost of neodymium magnets is economically unviable,

Lifting parameters

Highest magnetic holding force – what contributes to it?

The force parameter is a measurement result executed under specific, ideal conditions:
  • using a sheet made of low-carbon steel, acting as a circuit closing element
  • whose transverse dimension equals approx. 10 mm
  • with an ideally smooth contact surface
  • under conditions of ideal adhesion (surface-to-surface)
  • during detachment in a direction perpendicular to the mounting surface
  • at ambient temperature approx. 20 degrees Celsius

Lifting capacity in practice – influencing factors

During everyday use, the actual holding force is determined by a number of factors, listed from most significant:
  • Distance – existence of any layer (paint, dirt, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
  • Loading method – declared lifting capacity refers to detachment vertically. When slipping, the magnet holds much less (often approx. 20-30% of maximum force).
  • Base massiveness – too thin steel causes magnetic saturation, causing part of the flux to be wasted into the air.
  • Material composition – not every steel reacts the same. Alloy additives weaken the attraction effect.
  • Surface structure – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
  • Thermal environment – temperature increase causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.

Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate lowers the holding force.

Warnings
Material brittleness

Watch out for shards. Magnets can explode upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.

Implant safety

People with a pacemaker have to keep an large gap from magnets. The magnetism can disrupt the operation of the life-saving device.

Heat warning

Avoid heat. Neodymium magnets are susceptible to temperature. If you require resistance above 80°C, inquire about special high-temperature series (H, SH, UH).

Metal Allergy

Some people suffer from a sensitization to Ni, which is the common plating for NdFeB magnets. Frequent touching can result in an allergic reaction. It is best to wear protective gloves.

Do not drill into magnets

Dust created during cutting of magnets is combustible. Avoid drilling into magnets unless you are an expert.

Serious injuries

Protect your hands. Two powerful magnets will snap together instantly with a force of massive weight, crushing anything in their path. Be careful!

GPS and phone interference

GPS units and smartphones are extremely sensitive to magnetic fields. Direct contact with a strong magnet can permanently damage the sensors in your phone.

Protect data

Equipment safety: Neodymium magnets can damage payment cards and delicate electronics (pacemakers, medical aids, mechanical watches).

Conscious usage

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

Product not for children

Strictly store magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are tragic.
