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.

Yes, the hook is an element screwed into a bushing with a metric thread (e.g., M4, M5, M6 - check description). Check the thread size in the product specification to select matching replacements.

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.

Thanks to the metal cover, attraction force is concentrated, which significantly increases capacity compared to a bare magnet. Additionally, steel protects the brittle magnet from cracking upon hitting the ceiling or beam.

For outdoor use (in rain), metal hangers may eventually develop a rusty coating over time. In home and office conditions, they will serve for many years without signs of wear.

Strengths as well as weaknesses of Nd₂Fe₁₄B magnets.

Benefits

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

Their power remains stable, and after approximately ten years it decreases only by ~1% (theoretically),
They are noted for resistance to demagnetization induced by presence of other magnetic fields,
In other words, due to the reflective finish of nickel, the element gains visual value,
The surface of neodymium magnets generates a powerful magnetic field – this is a distinguishing feature,
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...
Possibility of accurate modeling as well as optimizing to atypical needs,
Key role in modern technologies – they serve a role in data components, brushless drives, medical equipment, and other advanced devices.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Disadvantages

Characteristics of disadvantages of neodymium magnets: application proposals

At strong impacts they can break, therefore we recommend 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 strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
When exposed to humidity, magnets usually 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.
We recommend cover - magnetic mount, due to difficulties in creating threads inside the magnet and complex forms.
Potential hazard to health – tiny shards of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. It is also worth noting that small components of these magnets are able to be problematic in diagnostics medical in case of swallowing.
Due to expensive raw materials, their price exceeds standard values,

Lifting parameters

Optimal lifting capacity of a neodymium magnet – what contributes to it?

Breakaway force was defined for ideal contact conditions, assuming:

with the contact of a yoke made of low-carbon steel, ensuring maximum field concentration
whose thickness reaches at least 10 mm
characterized by smoothness
without the slightest insulating layer between the magnet and steel
under axial application of breakaway force (90-degree angle)
in stable room temperature

What influences lifting capacity in practice

Please note that the magnet holding may be lower subject to elements below, starting with the most relevant:

Distance – the presence of foreign body (rust, dirt, gap) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
Loading method – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
Material type – ideal substrate is high-permeability steel. Cast iron may have worse magnetic properties.
Surface condition – ground elements guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
Heat – NdFeB sinters have a negative temperature coefficient. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).

Lifting capacity was assessed using a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. In addition, even a small distance between the magnet and the plate decreases the load capacity.

Warnings

Metal Allergy

Nickel alert: The Ni-Cu-Ni coating consists of nickel. If skin irritation appears, immediately stop working with magnets and use protective gear.

Demagnetization risk

Do not overheat. Neodymium magnets are susceptible to heat. If you need operation above 80°C, look for HT versions (H, SH, UH).

Pinching danger

Risk of injury: The pulling power is so great that it can cause hematomas, pinching, and broken bones. Use thick gloves.

Keep away from electronics

Navigation devices and smartphones are highly sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the internal compass in your phone.

This is not a toy

Product intended for adults. Tiny parts pose a choking risk, causing intestinal necrosis. Store out of reach of kids and pets.

Cards and drives

Intense magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Stay away of at least 10 cm.

Medical implants

For implant holders: Powerful magnets disrupt medical devices. Maintain minimum 30 cm distance or ask another person to work with the magnets.

Handling rules

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

Fire warning

Machining of neodymium magnets poses a fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Fragile material

Watch out for shards. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Wear goggles.
