A hook magnet is an ideal solution for quick mounting of banners, signs, and markings on steel ceiling structures. 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. This gives huge application flexibility and allows adapting the holder to current needs.
You will get the greatest force by mounting the magnet on a thick, smooth steel surface vertically. When mounting on a wall (vertically), the holding force is much lower due to shear force (the magnet may slide).
The cup acts as a magnetic armature, intensifying the neodymium action and increasing efficiency. Additionally, steel protects the brittle magnet from cracking upon hitting the ceiling or beam.
Standard holders are coated with a layer of nickel or zinc, which protects them from corrosion indoors. In home and office conditions, they will serve for many years without signs of wear.

Strengths and weaknesses of Nd2Fe14B magnets.

Benefits

Apart from their notable power, neodymium magnets have these key benefits:
  • They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (based on calculations),
  • They maintain their magnetic properties even under strong external field,
  • In other words, due to the metallic layer of gold, the element is aesthetically pleasing,
  • Magnets have exceptionally strong magnetic induction on the working surface,
  • Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
  • Thanks to freedom in forming and the capacity to customize to complex applications,
  • Versatile presence in high-tech industry – they are utilized in hard drives, brushless drives, diagnostic systems, also modern systems.
  • Thanks to their power density, small magnets offer high operating force, with minimal size,

Cons

Disadvantages of NdFeB magnets:
  • To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
  • Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures 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 protecting against moisture
  • Due to limitations in producing nuts and complicated forms in magnets, we recommend using a housing - magnetic holder.
  • Potential hazard related to microscopic parts of magnets are risky, if swallowed, which gains importance in the context of child health protection. It is also worth noting that small elements of these devices can complicate diagnosis medical when they are in the body.
  • Due to expensive raw materials, their price is relatively high,

Holding force characteristics

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

The specified lifting capacity refers to the limit force, obtained under ideal test conditions, specifically:
  • on a base made of mild steel, optimally conducting the magnetic flux
  • whose thickness is min. 10 mm
  • characterized by lack of roughness
  • without any air gap between the magnet and steel
  • under axial force direction (90-degree angle)
  • at ambient temperature room level

Determinants of lifting force in real conditions

Real force is affected by specific conditions, mainly (from priority):
  • Distance (betwixt the magnet and the metal), since even a very small distance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to varnish, corrosion or debris).
  • Direction of force – maximum parameter is obtained only during perpendicular pulling. The shear force of the magnet along the plate is standardly many times smaller (approx. 1/5 of the lifting capacity).
  • Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
  • Material type – ideal substrate is high-permeability steel. Stainless steels may attract less.
  • Surface quality – the more even the plate, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
  • Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).

Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the load capacity is reduced by as much as 75%. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.

H&S for magnets
Danger to the youngest

NdFeB magnets are not intended for children. Swallowing multiple magnets can lead to them pinching intestinal walls, which constitutes a direct threat to life and requires urgent medical intervention.

Power loss in heat

Monitor thermal conditions. Heating the magnet to high heat will permanently weaken its properties and strength.

Combustion hazard

Mechanical processing of NdFeB material carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.

Do not underestimate power

Exercise caution. Rare earth magnets attract from a long distance and connect with huge force, often faster than you can move away.

Sensitization to coating

Allergy Notice: The nickel-copper-nickel coating consists of nickel. If an allergic reaction appears, immediately stop working with magnets and use protective gear.

Keep away from electronics

A powerful magnetic field interferes with the functioning of magnetometers in phones and navigation systems. Maintain magnets close to a smartphone to prevent breaking the sensors.

Keep away from computers

Equipment safety: Strong magnets can ruin data carriers and sensitive devices (pacemakers, medical aids, mechanical watches).

Eye protection

NdFeB magnets are ceramic materials, meaning they are prone to chipping. Impact of two magnets will cause them shattering into small pieces.

Bodily injuries

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

Implant safety

For implant holders: Strong magnetic fields disrupt medical devices. Maintain at least 30 cm distance or request help to work with the magnets.
