Holders with a hook are indispensable in large-format stores and warehouses for suspending advertisements (POS systems). You can use them to organize wires, hang tools, or clothes on metal racks.

The magnet has a standard threaded socket, which allows replacing the hook with any other accessory with a thread. 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. A bare magnet could crack upon sudden application to metal, and the holder is resistant to this.

For outdoor use (in rain), metal hangers may eventually develop a rusty coating over time. Metal elements can rust with constant contact with atmospheric moisture.

Pros and cons of Nd₂Fe₁₄B magnets.

Strengths

Besides their high retention, neodymium magnets are valued for these benefits:

They have stable power, and over nearly 10 years their performance decreases symbolically – ~1% (in testing),
They maintain their magnetic properties even under external field action,
Thanks to the reflective finish, the plating of Ni-Cu-Ni, gold, or silver gives an modern appearance,
Magnets possess impressive magnetic induction on the active area,
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...
In view of the ability of accurate shaping and adaptation to individualized solutions, magnetic components can be produced in a variety of geometric configurations, which increases their versatility,
Huge importance in modern technologies – they are used in hard drives, electric motors, medical equipment, and industrial machines.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Weaknesses

Disadvantages of NdFeB magnets:

Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a steel housing, which not only secures them against impacts but also increases their durability
NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
We suggest cover - magnetic mount, due to difficulties in producing nuts inside the magnet and complicated shapes.
Health risk to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child safety. Additionally, small components of these products can disrupt the diagnostic process medical in case of swallowing.
Due to complex production process, their price is relatively high,

Lifting parameters

Optimal lifting capacity of a neodymium magnet – what affects it?

The lifting capacity listed is a theoretical maximum value performed under specific, ideal conditions:

on a block made of structural steel, perfectly concentrating the magnetic field
possessing a massiveness of at least 10 mm to ensure full flux closure
with an ideally smooth contact surface
under conditions of no distance (metal-to-metal)
for force acting at a right angle (in the magnet axis)
in temp. approx. 20°C

Determinants of practical lifting force of a magnet

In real-world applications, the actual holding force results from several key aspects, presented from crucial:

Distance – the presence of foreign body (paint, tape, air) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
Force direction – catalog parameter refers to pulling vertically. When attempting to slide, the magnet exhibits much less (typically approx. 20-30% of nominal force).
Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
Material type – the best choice is pure iron steel. Cast iron may attract less.
Surface quality – the smoother and more polished the plate, the better the adhesion and stronger the hold. Roughness creates an air distance.
Temperature influence – high temperature reduces pulling force. Too high temperature can permanently demagnetize the magnet.

Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the holding force is lower. In addition, even a small distance between the magnet and the plate decreases the load capacity.

Safe handling of NdFeB magnets

Hand protection

Protect your hands. Two powerful magnets will join instantly with a force of several hundred kilograms, crushing everything in their path. Be careful!

Precision electronics

Note: neodymium magnets produce a field that interferes with precision electronics. Keep a separation from your mobile, device, and GPS.

Mechanical processing

Powder generated during machining of magnets is flammable. Do not drill into magnets unless you are an expert.

Material brittleness

Despite metallic appearance, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.

Implant safety

People with a heart stimulator should maintain an safe separation from magnets. The magnetic field can disrupt the functioning of the life-saving device.

Handling guide

Before starting, check safety instructions. Sudden snapping can break the magnet or injure your hand. Think ahead.

This is not a toy

NdFeB magnets are not suitable for play. Eating multiple magnets can lead to them attracting across intestines, which constitutes a critical condition and necessitates immediate surgery.

Allergic reactions

Certain individuals suffer from a hypersensitivity to nickel, which is the common plating for neodymium magnets. Frequent touching might lead to an allergic reaction. We strongly advise wear safety gloves.

Protect data

Very strong magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Keep a distance of at least 10 cm.

Operating temperature

Standard neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. Damage is permanent.
