Holders with a hook are indispensable in large-format stores and warehouses for suspending advertisements (POS systems). You can use them to organize wires, hang tools, or clothes on metal racks.

Yes, the hook is an element screwed into a bushing with a metric thread (e.g., M4, M5, M6 - check description). 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., 43.00 kg) refers to perpendicular (vertical) force when mounted on the ceiling. If you hang the magnet on a wall, the real capacity is approx. 20-30% of the nominal value.

Thanks to the metal cover, attraction force is concentrated, which significantly increases capacity compared to a bare magnet. A bare magnet could crack upon sudden application to metal, and the holder is resistant to this.

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.

Advantages as well as disadvantages of neodymium magnets.

Pros

In addition to their magnetic capacity, neodymium magnets provide the following advantages:

They have constant strength, and over around ten years their performance decreases symbolically – ~1% (according to theory),
They are noted for resistance to demagnetization induced by external disturbances,
By applying a reflective layer of nickel, the element acquires an aesthetic look,
Magnets are distinguished by exceptionally strong magnetic induction on the surface,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
Possibility of custom shaping as well as adjusting to specific requirements,
Key role in high-tech industry – they are commonly used in computer drives, motor assemblies, medical equipment, as well as modern systems.
Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in small systems

Limitations

Disadvantages of neodymium magnets:

At strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest 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.
We suggest casing - magnetic mount, due to difficulties in producing threads inside the magnet and complicated forms.
Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child safety. It is also worth noting that small elements of these products can disrupt the diagnostic process medical in case of swallowing.
Due to expensive raw materials, their price is higher than average,

Lifting parameters

Maximum holding power of the magnet – what affects it?

The specified lifting capacity concerns the limit force, measured under optimal environment, meaning:

using a plate made of mild steel, functioning as a circuit closing element
possessing a massiveness of minimum 10 mm to ensure full flux closure
with an ideally smooth contact surface
without the slightest air gap between the magnet and steel
for force applied at a right angle (pull-off, not shear)
at temperature approx. 20 degrees Celsius

Key elements affecting lifting force

In practice, the real power depends on several key aspects, listed from crucial:

Air gap (betwixt the magnet and the metal), since even a microscopic clearance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to varnish, rust or dirt).
Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
Material composition – different alloys reacts the same. Alloy additives worsen the interaction with the magnet.
Surface finish – full contact is possible only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
Heat – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity was determined using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under parallel forces the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate reduces the lifting capacity.

Safety rules for work with neodymium magnets

Fire warning

Machining of neodymium magnets poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

Safe operation

Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.

Magnetic media

Very strong magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Keep a distance of min. 10 cm.

Warning for heart patients

Warning for patients: Strong magnetic fields disrupt electronics. Keep at least 30 cm distance or ask another person to handle the magnets.

This is not a toy

Only for adults. Small elements pose a choking risk, leading to severe trauma. Store out of reach of kids and pets.

Maximum temperature

Regular neodymium magnets (grade N) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.

GPS and phone interference

Navigation devices and smartphones are extremely susceptible to magnetism. Direct contact with a powerful NdFeB magnet can permanently damage the internal compass in your phone.

Avoid contact if allergic

Certain individuals experience a contact allergy to Ni, which is the standard coating for NdFeB magnets. Prolonged contact may cause skin redness. We recommend wear protective gloves.

Physical harm

Pinching hazard: The attraction force is so great that it can cause blood blisters, pinching, and broken bones. Use thick gloves.

Fragile material

Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.
