A hook magnet is an ideal solution for quick mounting of banners, signs, and markings on steel ceiling structures. 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). 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. If you hang the magnet on a wall, the real capacity is approx. 20-30% of the nominal value.

The steel housing (cup) shields the magnetic field, directing all its power downwards, onto the contact surface. The housing ensures mechanical durability, which is important in industrial and assembly conditions.

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 as well as weaknesses of Nd₂Fe₁₄B magnets.

Advantages

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

They have unchanged lifting capacity, and over around 10 years their attraction force decreases symbolically – ~1% (according to theory),
They have excellent resistance to magnetism drop as a result of external magnetic sources,
A magnet with a smooth silver surface has an effective appearance,
Magnets are distinguished by excellent magnetic induction on the active area,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
Thanks to flexibility in shaping and the capacity to adapt to specific needs,
Significant place in modern industrial fields – they are commonly used in HDD drives, electromotive mechanisms, diagnostic systems, also technologically advanced constructions.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which allows their use in compact constructions

Weaknesses

Disadvantages of NdFeB magnets:

At strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
Neodymium magnets lose their force 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 durability even at temperatures up to 230°C
Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
We suggest casing - magnetic holder, due to difficulties in producing threads inside the magnet and complex shapes.
Possible danger to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the context of child health protection. Furthermore, small components of these devices are able to complicate diagnosis medical in case of swallowing.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Pull force analysis

Magnetic strength at its maximum – what affects it?

The load parameter shown refers to the peak performance, measured under optimal environment, specifically:

with the contact of a yoke made of special test steel, ensuring maximum field concentration
whose transverse dimension is min. 10 mm
characterized by even structure
under conditions of gap-free contact (metal-to-metal)
during detachment in a direction vertical to the plane
in stable room temperature

Lifting capacity in practice – influencing factors

During everyday use, the actual holding force results from a number of factors, presented from most significant:

Distance – existence of foreign body (paint, tape, air) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
Angle of force application – maximum parameter is reached only during pulling at a 90° angle. The force required to slide of the magnet along the surface is standardly many times lower (approx. 1/5 of the lifting capacity).
Base massiveness – too thin steel causes magnetic saturation, causing part of the flux to be wasted into the air.
Steel grade – ideal substrate is pure iron steel. Hardened steels may generate lower lifting capacity.
Base smoothness – the more even the plate, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
Thermal conditions – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the holding force is lower. Moreover, even a minimal clearance between the magnet and the plate reduces the holding force.

Safety rules for work with NdFeB magnets

Crushing risk

Large magnets can smash fingers instantly. Under no circumstances put your hand between two strong magnets.

Nickel allergy

Some people experience a sensitization to Ni, which is the typical protective layer for NdFeB magnets. Prolonged contact can result in a rash. It is best to use safety gloves.

Protective goggles

Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.

Implant safety

Patients with a pacemaker must keep an safe separation from magnets. The magnetism can disrupt the functioning of the implant.

Fire warning

Combustion risk: Neodymium dust is explosive. Do not process magnets in home conditions as this risks ignition.

Danger to the youngest

Absolutely keep magnets out of reach of children. Ingestion danger is high, and the consequences of magnets connecting inside the body are fatal.

Data carriers

Avoid bringing magnets near a purse, computer, or screen. The magnetic field can permanently damage these devices and wipe information from cards.

GPS and phone interference

Remember: rare earth magnets produce a field that confuses sensitive sensors. Keep a separation from your phone, tablet, and GPS.

Demagnetization risk

Do not overheat. NdFeB magnets are susceptible to temperature. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).

Safe operation

Handle magnets with awareness. Their huge power can surprise even professionals. Be vigilant and respect their power.
