They serve to create mobile suspension points without the need to drill holes in beams. 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. Thanks to this, one magnet can perform many functions - sometimes be a hook, and sometimes a holder for a bolt.

The given value defines the maximum load when suspended under a thick, horizontal ceiling beam. When mounting on a wall (vertically), the holding force is much lower due to shear force (the magnet may slide).

Thanks to the metal cover, attraction force is concentrated, which significantly increases capacity compared to a bare magnet. A bare magnet could crack upon sudden application to metal, and the holder is resistant to this.

Standard holders are coated with a layer of nickel or zinc, which protects them from corrosion indoors. If you are looking for an outdoor hanger, choose a model in rubberized or plastic housing, which is tight.

Advantages and disadvantages of rare earth magnets.

Advantages

Besides their exceptional strength, neodymium magnets offer the following advantages:

They do not lose magnetism, even over nearly 10 years – the reduction in power is only ~1% (according to tests),
They possess excellent resistance to weakening of magnetic properties as a result of opposing magnetic fields,
The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to look better,
They are known for high magnetic induction at the operating surface, which affects their effectiveness,
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...
Possibility of exact forming as well as optimizing to precise requirements,
Wide application in electronics industry – they are utilized in data components, brushless drives, medical equipment, as well as multitasking production systems.
Thanks to their power density, small magnets offer high operating force, occupying minimum space,

Weaknesses

Disadvantages of NdFeB magnets:

At very strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
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 protecting against moisture
Limited possibility of making threads in the magnet and complex shapes - recommended is a housing - magnet mounting.
Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the context of child health protection. Additionally, small elements of these magnets can disrupt the diagnostic process medical when they are in the body.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities

Lifting parameters

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

Holding force of 112.00 kg is a theoretical maximum value executed under standard conditions:

with the contact of a sheet made of special test steel, guaranteeing full magnetic saturation
whose transverse dimension reaches at least 10 mm
with a plane cleaned and smooth
without the slightest clearance between the magnet and steel
under perpendicular force direction (90-degree angle)
at room temperature

Practical aspects of lifting capacity – factors

In real-world applications, the actual lifting capacity depends on a number of factors, presented from crucial:

Distance – the presence of foreign body (rust, dirt, air) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
Angle of force application – highest force is available only during pulling at a 90° angle. The shear force of the magnet along the plate is usually many times smaller (approx. 1/5 of the lifting capacity).
Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
Metal type – not every steel attracts identically. Alloy additives worsen the attraction effect.
Base smoothness – the more even the plate, the larger the contact zone and stronger the hold. Roughness creates an air distance.
Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).

Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate decreases the load capacity.

Precautions when working with NdFeB magnets

Crushing force

Big blocks can crush fingers in a fraction of a second. Do not place your hand betwixt two attracting surfaces.

Keep away from electronics

Navigation devices and smartphones are extremely susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can ruin the internal compass in your phone.

Choking Hazard

Neodymium magnets are not suitable for play. Eating multiple magnets may result in them pinching intestinal walls, which poses a critical condition and necessitates urgent medical intervention.

ICD Warning

For implant holders: Strong magnetic fields disrupt electronics. Maintain minimum 30 cm distance or ask another person to handle the magnets.

Electronic devices

Very strong magnetic fields can erase data on payment cards, hard drives, and storage devices. Keep a distance of at least 10 cm.

Metal Allergy

A percentage of the population experience a sensitization to Ni, which is the common plating for neodymium magnets. Prolonged contact might lead to skin redness. We strongly advise wear safety gloves.

Risk of cracking

Watch out for shards. Magnets can explode upon violent connection, launching shards into the air. Wear goggles.

Handling guide

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

Fire warning

Drilling and cutting of neodymium magnets poses a fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.

Power loss in heat

Watch the temperature. Heating the magnet above 80 degrees Celsius will permanently weaken its properties and pulling force.

Important! Learn more about risks in the article: Magnet Safety Guide.
