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. This gives huge application flexibility and allows adapting the holder to current needs.

The given value defines the maximum load when suspended under a thick, horizontal ceiling beam. If you hang the magnet on a wall, the real capacity is approx. 20-30% of the nominal value.

The cup acts as a magnetic armature, intensifying the neodymium action and increasing efficiency. 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.

Strengths as well as weaknesses of Nd₂Fe₁₄B magnets.

Advantages

Apart from their strong holding force, neodymium magnets have these key benefits:

They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (based on calculations),
Neodymium magnets prove to be remarkably resistant to magnetic field loss caused by external interference,
In other words, due to the aesthetic finish of silver, the element gains a professional look,
They feature high magnetic induction at the operating surface, which increases their power,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
Thanks to versatility in designing and the capacity to adapt to individual projects,
Wide application in innovative solutions – they are commonly used in computer drives, electromotive mechanisms, advanced medical instruments, as well as industrial machines.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in compact constructions

Disadvantages

Disadvantages of neodymium magnets:

To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 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.
Limited ability of creating nuts in the magnet and complicated shapes - recommended is cover - magnet mounting.
Potential hazard resulting from small fragments of magnets can be dangerous, 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 complicate diagnosis medical after entering the body.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Pull force analysis

Best holding force of the magnet in ideal parameters – what affects it?

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

with the application of a sheet made of low-carbon steel, ensuring full magnetic saturation
with a cross-section no less than 10 mm
with an ideally smooth contact surface
without the slightest clearance between the magnet and steel
for force applied at a right angle (pull-off, not shear)
at conditions approx. 20°C

Magnet lifting force in use – key factors

In real-world applications, the actual lifting capacity is determined by a number of factors, presented from most significant:

Gap (betwixt the magnet and the plate), since even a very small distance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to varnish, rust or dirt).
Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
Material type – ideal substrate is high-permeability steel. Hardened steels may have worse magnetic properties.
Base smoothness – the more even the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
Operating temperature – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity was assessed with the use of a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under attempts to slide the magnet the holding force is lower. In addition, even a minimal clearance between the magnet and the plate lowers the holding force.

H&S for magnets

Demagnetization risk

Regular neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.

Allergy Warning

Medical facts indicate that nickel (standard magnet coating) is a common allergen. If your skin reacts to metals, prevent direct skin contact or select coated magnets.

Pinching danger

Pinching hazard: The pulling power is so great that it can result in blood blisters, crushing, and even bone fractures. Protective gloves are recommended.

Do not underestimate power

Use magnets with awareness. Their powerful strength can surprise even experienced users. Plan your moves and respect their power.

Flammability

Mechanical processing of NdFeB material carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.

Life threat

Life threat: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.

Adults only

Product intended for adults. Tiny parts can be swallowed, causing severe trauma. Store away from kids and pets.

Electronic hazard

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

Impact on smartphones

Remember: neodymium magnets generate a field that interferes with sensitive sensors. Maintain a separation from your phone, device, and navigation systems.

Eye protection

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