Holders with a hook are indispensable in large-format stores and warehouses for suspending advertisements (POS systems). In workshops and garages, they work perfectly for guiding cables or hanging work lighting.

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., 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).

Thanks to the metal cover, attraction force is concentrated, which significantly increases capacity compared to a bare magnet. Additionally, steel protects the brittle magnet from cracking upon hitting the ceiling or beam.

For outdoor use (in rain), metal hangers may eventually develop a rusty coating over time. In home and office conditions, they will serve for many years without signs of wear.

Advantages and disadvantages of neodymium magnets.

Strengths

Apart from their notable holding force, neodymium magnets have these key benefits:

They virtually do not lose power, because even after ten years the performance loss is only ~1% (according to literature),
They possess excellent resistance to magnetism drop due to external fields,
By using a smooth layer of gold, the element gains an nice look,
Magnetic induction on the surface of the magnet is exceptional,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
Thanks to modularity in designing and the ability to customize to complex applications,
Fundamental importance in future technologies – they are utilized in magnetic memories, electromotive mechanisms, precision medical tools, as well as modern systems.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Disadvantages

Problematic aspects of neodymium magnets: tips and applications.

At very strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
Due to limitations in realizing nuts and complicated shapes in magnets, we propose using casing - magnetic mount.
Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting the youngest. It is also worth noting that tiny parts of these products can complicate diagnosis medical when they are in the body.
Due to complex production process, their price is relatively high,

Holding force characteristics

Breakaway strength of the magnet in ideal conditions – what affects it?

The specified lifting capacity represents the limit force, measured under laboratory conditions, meaning:

using a plate made of high-permeability steel, functioning as a ideal flux conductor
possessing a massiveness of min. 10 mm to ensure full flux closure
with a surface free of scratches
with total lack of distance (without paint)
for force applied at a right angle (in the magnet axis)
at ambient temperature room level

Determinants of lifting force in real conditions

Bear in mind that the magnet holding will differ influenced by the following factors, in order of importance:

Gap (between the magnet and the plate), since even a very small clearance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to varnish, corrosion or dirt).
Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Chemical composition of the base – mild steel gives the best results. Alloy steels reduce magnetic permeability and lifting capacity.
Surface structure – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).

Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, in contrast under parallel forces the load capacity is reduced by as much as fivefold. In addition, even a minimal clearance between the magnet and the plate decreases the load capacity.

Safety rules for work with NdFeB magnets

Health Danger

Warning for patients: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or ask another person to handle the magnets.

Shattering risk

Neodymium magnets are ceramic materials, meaning they are fragile like glass. Impact of two magnets will cause them cracking into small pieces.

Handling guide

Before use, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.

Allergy Warning

Studies show that nickel (the usual finish) is a potent allergen. If your skin reacts to metals, refrain from direct skin contact or select encased magnets.

Heat sensitivity

Control the heat. Exposing the magnet to high heat will permanently weaken its properties and strength.

Precision electronics

Navigation devices and mobile phones are extremely susceptible to magnetism. Close proximity with a powerful NdFeB magnet can ruin the internal compass in your phone.

Magnetic media

Equipment safety: Neodymium magnets can damage payment cards and delicate electronics (heart implants, hearing aids, timepieces).

Finger safety

Risk of injury: The attraction force is so great that it can result in blood blisters, crushing, and even bone fractures. Use thick gloves.

Keep away from children

Always store magnets out of reach of children. Choking hazard is significant, and the effects of magnets clamping inside the body are fatal.

Machining danger

Dust produced during cutting of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
