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.

The nominal capacity (e.g., 38.00 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.

The cup acts as a magnetic armature, intensifying the neodymium action and increasing efficiency. The housing ensures mechanical durability, which is important in industrial and assembly conditions.

For outdoor use (in rain), metal hangers may eventually develop a rusty coating over time. If you are looking for an outdoor hanger, choose a model in rubberized or plastic housing, which is tight.

Advantages as well as disadvantages of neodymium magnets.

Advantages

Apart from their consistent magnetic energy, neodymium magnets have these key benefits:

Their magnetic field is durable, and after around 10 years it drops only by ~1% (according to research),
They maintain their magnetic properties even under external field action,
By applying a decorative layer of nickel, the element presents an modern look,
Magnetic induction on the top side of the magnet remains maximum,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
Possibility of exact forming and optimizing to complex needs,
Fundamental importance in future technologies – they find application in HDD drives, electric motors, diagnostic systems, and technologically advanced constructions.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in compact constructions

Cons

Disadvantages of neodymium magnets:

To avoid cracks under impact, we recommend using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
Due to limitations in producing nuts and complex forms in magnets, we recommend using cover - magnetic holder.
Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. It is also worth noting that small elements of these products are able to complicate diagnosis medical in case of swallowing.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Pull force analysis

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

The load parameter shown refers to the limit force, recorded under optimal environment, specifically:

on a base made of mild steel, effectively closing the magnetic flux
whose thickness is min. 10 mm
with a surface cleaned and smooth
under conditions of ideal adhesion (surface-to-surface)
for force applied at a right angle (pull-off, not shear)
at temperature room level

What influences lifting capacity in practice

It is worth knowing that the working load will differ subject to elements below, in order of importance:

Clearance – the presence of foreign body (rust, tape, gap) 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 applying parallel force, the magnet exhibits much less (often approx. 20-30% of nominal force).
Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
Plate material – mild steel attracts best. Alloy steels reduce magnetic properties and lifting capacity.
Smoothness – ideal contact is obtained only on polished steel. Rough texture create air cushions, reducing force.
Temperature influence – hot environment weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity was assessed using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet and the plate decreases the lifting capacity.

H&S for magnets

Allergy Warning

Medical facts indicate that the nickel plating (the usual finish) is a potent allergen. For allergy sufferers, prevent direct skin contact or select encased magnets.

Do not drill into magnets

Fire hazard: Rare earth powder is highly flammable. Do not process magnets without safety gear as this may cause fire.

Magnets are brittle

Despite the nickel coating, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.

Serious injuries

Pinching hazard: The attraction force is so great that it can result in blood blisters, pinching, and even bone fractures. Protective gloves are recommended.

Precision electronics

Note: rare earth magnets generate a field that confuses sensitive sensors. Keep a safe distance from your phone, tablet, and GPS.

Do not give to children

Only for adults. Tiny parts pose a choking risk, leading to serious injuries. Keep out of reach of children and animals.

Health Danger

People with a pacemaker have to keep an large gap from magnets. The magnetism can interfere with the functioning of the implant.

Cards and drives

Powerful magnetic fields can destroy records on payment cards, HDDs, and storage devices. Maintain a gap of at least 10 cm.

Handling rules

Before use, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.

Power loss in heat

Avoid heat. NdFeB magnets are sensitive to heat. If you need operation above 80°C, inquire about HT versions (H, SH, UH).
