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.

The magnet has a standard threaded socket, which allows replacing the hook with any other accessory with a thread. Check the thread size in the product specification to select matching replacements.

The nominal capacity (e.g., 38.00 kg) refers to perpendicular (vertical) force when mounted on the ceiling. For heavy ceiling ads or tools, we recommend choosing a magnet with a considerable power reserve.

Thanks to the metal cover, attraction force is concentrated, which significantly increases capacity compared to a bare magnet. 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.

Benefits

In addition to their pulling strength, neodymium magnets provide the following advantages:

They virtually do not lose power, because even after ten years the performance loss is only ~1% (based on calculations),
Neodymium magnets are distinguished by extremely resistant to magnetic field loss caused by magnetic disturbances,
In other words, due to the glossy surface of silver, the element gains a professional look,
Neodymium magnets ensure maximum magnetic induction on a contact point, which increases force concentration,
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 detailed creating as well as adapting to individual needs,
Fundamental importance in high-tech industry – they are used in HDD drives, motor assemblies, diagnostic systems, and technologically advanced constructions.
Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Disadvantages

Characteristics of disadvantages of neodymium magnets and proposals for their use:

Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, which not only protects them against impacts but also increases their durability
When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power 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
Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
Due to limitations in realizing threads and complex shapes in magnets, we recommend using cover - magnetic holder.
Possible danger resulting from small fragments of magnets are risky, if swallowed, which gains importance in the context of child safety. Additionally, tiny parts of these products can be problematic in diagnostics medical in case of swallowing.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Holding force characteristics

Maximum lifting capacity of the magnet – what affects it?

Magnet power was determined for the most favorable conditions, including:

with the application of a yoke made of low-carbon steel, guaranteeing maximum field concentration
with a thickness minimum 10 mm
characterized by lack of roughness
with zero gap (without coatings)
under perpendicular force direction (90-degree angle)
at ambient temperature approx. 20 degrees Celsius

Practical lifting capacity: influencing factors

In real-world applications, the actual lifting capacity is determined by several key aspects, listed from the most important:

Distance (between the magnet and the plate), as even a tiny distance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to paint, rust or dirt).
Load vector – maximum parameter is obtained only during perpendicular pulling. The shear force of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
Plate material – low-carbon steel gives the best results. Alloy steels reduce magnetic properties and lifting capacity.
Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity was determined using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet and the plate reduces the load capacity.

Warnings

Warning for heart patients

Individuals with a ICD must maintain an safe separation from magnets. The magnetism can disrupt the operation of the implant.

Electronic hazard

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

GPS Danger

An intense magnetic field interferes with the functioning of compasses in phones and navigation systems. Maintain magnets near a device to avoid breaking the sensors.

Do not overheat magnets

Avoid heat. Neodymium magnets are susceptible to temperature. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).

Fire risk

Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this risks ignition.

Nickel allergy

Medical facts indicate that the nickel plating (standard magnet coating) is a potent allergen. If your skin reacts to metals, prevent touching magnets with bare hands or choose encased magnets.

Handling guide

Be careful. Rare earth magnets attract from a distance and connect with huge force, often quicker than you can react.

Pinching danger

Mind your fingers. Two large magnets will join immediately with a force of massive weight, destroying anything in their path. Be careful!

Keep away from children

These products are not toys. Accidental ingestion of a few magnets can lead to them connecting inside the digestive tract, which constitutes a severe health hazard and requires urgent medical intervention.

Material brittleness

Neodymium magnets are ceramic materials, which means they are fragile like glass. Clashing of two magnets leads to them breaking into shards.
