A hook magnet is an ideal solution for quick mounting of banners, signs, and markings on steel ceiling structures. It is a universal hanger that you can move to another place at any time without a trace.

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. For heavy ceiling ads or tools, we recommend choosing a magnet with a considerable power reserve.

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. If you are looking for an outdoor hanger, choose a model in rubberized or plastic housing, which is tight.

Advantages and disadvantages of neodymium magnets.

Advantages

Apart from their notable magnetism, neodymium magnets have these key benefits:

Their magnetic field remains stable, and after around ten years it drops only by ~1% (theoretically),
They maintain their magnetic properties even under close interference source,
By covering with a reflective layer of nickel, the element has an proper look,
Magnetic induction on the top side of the magnet remains exceptional,
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 accurate shaping and adapting to individual applications,
Key role in modern industrial fields – they are commonly used in data components, electromotive mechanisms, precision medical tools, as well as complex engineering applications.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Cons

Characteristics of disadvantages of neodymium magnets: application proposals

At strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
Due to limitations in producing nuts and complex shapes in magnets, we propose using casing - magnetic holder.
Possible danger to health – tiny shards of magnets can be dangerous, if swallowed, which gains importance in the context of child safety. It is also worth noting that small elements of these magnets are able to 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 increases costs of application in large quantities

Lifting parameters

Optimal lifting capacity of a neodymium magnet – what it depends on?

The declared magnet strength refers to the peak performance, recorded under laboratory conditions, namely:

with the contact of a yoke made of special test steel, ensuring maximum field concentration
with a thickness no less than 10 mm
with an ideally smooth contact surface
with total lack of distance (without paint)
for force applied at a right angle (pull-off, not shear)
at ambient temperature approx. 20 degrees Celsius

Lifting capacity in real conditions – factors

In real-world applications, the real power results from many variables, listed from most significant:

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 paint, corrosion or dirt).
Load vector – highest force is reached only during pulling at a 90° angle. The force required to slide of the magnet along the surface is standardly many times lower (approx. 1/5 of the lifting capacity).
Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
Material type – the best choice is pure iron steel. Hardened steels may generate lower lifting capacity.
Smoothness – ideal contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
Thermal environment – heating the magnet results in weakening of induction. Check the thermal limit for a given model.

Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Additionally, even a small distance between the magnet and the plate lowers the load capacity.

Precautions when working with neodymium magnets

Product not for children

NdFeB magnets are not suitable for play. Accidental ingestion of a few magnets may result in them connecting inside the digestive tract, which poses a direct threat to life and necessitates immediate surgery.

Machining danger

Mechanical processing of neodymium magnets poses a fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Heat sensitivity

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

Powerful field

Use magnets consciously. Their powerful strength can shock even professionals. Be vigilant and do not underestimate their force.

Shattering risk

Protect your eyes. Magnets can explode upon violent connection, launching shards into the air. Eye protection is mandatory.

GPS and phone interference

A powerful magnetic field negatively affects the operation of magnetometers in smartphones and GPS navigation. Do not bring magnets near a device to prevent breaking the sensors.

Data carriers

Powerful magnetic fields can destroy records on credit cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.

Crushing risk

Large magnets can crush fingers instantly. Never place your hand betwixt two attracting surfaces.

ICD Warning

Health Alert: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.

Allergy Warning

A percentage of the population suffer from a hypersensitivity to nickel, which is the standard coating for neodymium magnets. Prolonged contact can result in skin redness. We strongly advise wear safety gloves.
