Holders with a hook are indispensable in large-format stores and warehouses for suspending advertisements (POS systems). It is a universal hanger that you can move to another place at any time without a trace.

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., 112.00 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. 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. Metal elements can rust with constant contact with atmospheric moisture.

Pros as well as cons of Nd₂Fe₁₄B magnets.

Strengths

Besides their magnetic performance, neodymium magnets are valued for these benefits:

They have unchanged lifting capacity, and over more than ten years their performance decreases symbolically – ~1% (according to theory),
They maintain their magnetic properties even under close interference source,
A magnet with a shiny silver surface has better aesthetics,
Magnets have maximum magnetic induction on the outer side,
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...
Thanks to flexibility in constructing and the ability to adapt to complex applications,
Universal use in future technologies – they find application in mass storage devices, electric motors, diagnostic systems, as well as multitasking production systems.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Weaknesses

Disadvantages of NdFeB magnets:

At very strong impacts they can crack, 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 advise our specialized [AH] magnets, which work effectively even at 230°C.
When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
Due to limitations in creating threads and complicated shapes in magnets, we propose using casing - magnetic mechanism.
Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small elements of these magnets can be problematic in diagnostics medical after entering the body.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities

Lifting parameters

Maximum lifting force for a neodymium magnet – what it depends on?

The load parameter shown represents the peak performance, recorded under optimal environment, specifically:

with the use of a sheet made of low-carbon steel, ensuring maximum field concentration
possessing a thickness of at least 10 mm to avoid saturation
with an polished contact surface
with total lack of distance (without coatings)
during detachment in a direction vertical to the plane
at room temperature

Practical lifting capacity: influencing factors

In real-world applications, the actual lifting capacity is determined by many variables, listed from most significant:

Air gap (between the magnet and the plate), because even a tiny clearance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to varnish, rust or dirt).
Force direction – catalog parameter refers to pulling vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of generating force.
Material type – ideal substrate is pure iron steel. Cast iron may attract less.
Surface quality – the more even the plate, the better the adhesion and stronger the hold. Unevenness creates an air distance.
Thermal environment – temperature increase results in weakening of force. Check the maximum operating temperature for a given model.

Lifting capacity was assessed with the use of a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under parallel forces the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate lowers the lifting capacity.

Precautions when working with NdFeB magnets

Handling guide

Handle magnets with awareness. Their powerful strength can surprise even experienced users. Be vigilant and do not underestimate their force.

Keep away from electronics

GPS units and mobile phones are highly susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can decalibrate the internal compass in your phone.

No play value

Strictly store magnets out of reach of children. Choking hazard is high, and the consequences of magnets connecting inside the body are tragic.

Fragile material

Protect your eyes. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.

Metal Allergy

A percentage of the population suffer from a sensitization to nickel, which is the typical protective layer for neodymium magnets. Prolonged contact might lead to dermatitis. It is best to wear safety gloves.

Serious injuries

Watch your fingers. Two powerful magnets will join instantly with a force of massive weight, crushing everything in their path. Be careful!

Protect data

Avoid bringing magnets close to a purse, computer, or screen. The magnetic field can permanently damage these devices and erase data from cards.

Heat warning

Watch the temperature. Heating the magnet to high heat will permanently weaken its magnetic structure and strength.

Medical interference

Individuals with a ICD must keep an safe separation from magnets. The magnetism can disrupt the operation of the life-saving device.

Fire risk

Combustion risk: Neodymium dust is highly flammable. Do not process magnets without safety gear as this risks ignition.
