The steel cup acts as an armature, concentrating the magnetic flux and increasing capacity even several times. Thanks to this, the holder is more durable, resistant, and safer to mount. The threaded hole allows creating a functional mounting point in seconds.
The most important rule is choosing the appropriate length of the screw being screwed in. If the screw reaches the bottom of the bushing and is further tightened forcefully, it will destroy the magnet. It is worth securing the thread with thread glue if the connection is to be durable and resistant to vibrations.
These holders are commonly used in industry, advertising, and construction for quick mounting. They serve as a base for hooks, cable holders, organizers, and lighting systems. In the workshop, they can serve as mounting points for tools or measuring instruments.
The stated force is the maximum laboratory value obtained on a clean, smooth sheet. With thin sheets (e.g., car body, fridge casing), the force will be much smaller because steel cannot absorb the entire magnetic field. For side detachment (sliding), the force is only approx. 1/3 of nominal capacity.
Steel cups are usually coated with a layer of nickel (shiny) or zinc (matte/bright), providing basic protection. For outdoor applications, we recommend additional protection with varnish or choosing a rubberized (hermetic) version. The whole is well protected for standard workshop and industrial applications.

Strengths as well as weaknesses of rare earth magnets.

Benefits

Besides their tremendous field intensity, neodymium magnets offer the following advantages:
  • They have unchanged lifting capacity, and over nearly ten years their attraction force decreases symbolically – ~1% (according to theory),
  • They possess excellent resistance to magnetic field loss when exposed to external fields,
  • Thanks to the metallic finish, the plating of Ni-Cu-Ni, gold, or silver gives an clean appearance,
  • Magnetic induction on the working layer of the magnet turns out to be strong,
  • Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
  • In view of the possibility of free shaping and adaptation to custom needs, neodymium magnets can be created in a variety of forms and dimensions, which increases their versatility,
  • Significant place in high-tech industry – they are commonly used in data components, brushless drives, medical equipment, also complex engineering applications.
  • Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Disadvantages

Disadvantages of neodymium magnets:
  • Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a steel housing, which not only secures them against impacts but also raises their durability
  • We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
  • They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • We suggest cover - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complicated forms.
  • Potential hazard related to microscopic parts of magnets are risky, in case of ingestion, which gains importance in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices are able to complicate diagnosis medical when they are in the body.
  • High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Lifting parameters

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

The specified lifting capacity concerns the maximum value, recorded under laboratory conditions, specifically:
  • with the contact of a yoke made of special test steel, guaranteeing full magnetic saturation
  • whose transverse dimension is min. 10 mm
  • with a plane free of scratches
  • without the slightest air gap between the magnet and steel
  • for force acting at a right angle (pull-off, not shear)
  • in stable room temperature

Practical aspects of lifting capacity – factors

Bear in mind that the application force will differ subject to the following factors, starting with the most relevant:
  • Space between surfaces – every millimeter of separation (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
  • Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
  • Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
  • Steel type – mild steel gives the best results. Alloy steels reduce magnetic properties and lifting capacity.
  • Surface finish – full contact is obtained only on polished steel. Rough texture create air cushions, reducing force.
  • Thermal factor – hot environment reduces magnetic field. Too high temperature can permanently damage the magnet.

Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet and the plate lowers the lifting capacity.

H&S for magnets
Crushing force

Danger of trauma: The pulling power is so great that it can result in blood blisters, pinching, and even bone fractures. Protective gloves are recommended.

Warning for heart patients

People with a heart stimulator should keep an safe separation from magnets. The magnetic field can stop the operation of the life-saving device.

Protective goggles

NdFeB magnets are sintered ceramics, which means they are very brittle. Collision of two magnets will cause them shattering into small pieces.

Electronic hazard

Avoid bringing magnets near a wallet, computer, or TV. The magnetic field can destroy these devices and wipe information from cards.

Respect the power

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

Mechanical processing

Powder created during cutting of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.

Choking Hazard

Always keep magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are very dangerous.

Demagnetization risk

Do not overheat. NdFeB magnets are sensitive to heat. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).

Compass and GPS

Be aware: rare earth magnets produce a field that confuses precision electronics. Maintain a separation from your mobile, device, and navigation systems.

Sensitization to coating

Studies show that nickel (standard magnet coating) is a potent allergen. For allergy sufferers, refrain from touching magnets with bare hands and select encased magnets.
