Holders with a hook are indispensable in large-format stores and warehouses for suspending advertisements (POS systems). 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. Thanks to this, one magnet can perform many functions - sometimes be a hook, and sometimes a holder for a bolt.

The nominal capacity (e.g., 38.00 kg) refers to perpendicular (vertical) force when mounted on the ceiling. For heavy ceiling ads or tools, we recommend choosing a magnet with a considerable power reserve.

The steel housing (cup) shields the magnetic field, directing all its power downwards, onto the contact surface. Additionally, steel protects the brittle magnet from cracking upon hitting the ceiling or beam.

In the bathroom or kitchen, they will work perfectly, provided they are not directly splashed with water. In home and office conditions, they will serve for many years without signs of wear.

Advantages as well as disadvantages of rare earth magnets.

Pros

Apart from their consistent power, neodymium magnets have these key benefits:

Their power is durable, and after approximately 10 years it drops only by ~1% (according to research),
They retain their magnetic properties even under external field action,
The use of an refined layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
They show high magnetic induction at the operating surface, which affects their effectiveness,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
Considering the potential of accurate shaping and customization to custom solutions, neodymium magnets can be manufactured in a variety of geometric configurations, which amplifies use scope,
Huge importance in modern technologies – they serve a role in mass storage devices, drive modules, medical equipment, as well as other advanced devices.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which enables their usage in compact constructions

Disadvantages

Characteristics of disadvantages of neodymium magnets: tips and applications.

To avoid cracks under impact, we recommend using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
Neodymium 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 extremely resistant to heat
They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
We recommend casing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complicated shapes.
Potential hazard to health – tiny shards of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these products are able to disrupt the diagnostic process medical in case of swallowing.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities

Holding force characteristics

Highest magnetic holding force – what it depends on?

The force parameter is a measurement result performed under the following configuration:

with the application of a yoke made of low-carbon steel, ensuring full magnetic saturation
with a cross-section of at least 10 mm
with a surface cleaned and smooth
with direct contact (no paint)
during pulling in a direction perpendicular to the plane
in stable room temperature

Key elements affecting lifting force

Holding efficiency is affected by working environment parameters, such as (from most important):

Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
Load vector – highest force is obtained only during pulling at a 90° angle. The shear force of the magnet along the surface is usually 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).
Metal type – not every steel reacts the same. High carbon content weaken the attraction effect.
Smoothness – full contact is possible only on smooth steel. Any scratches and bumps create air cushions, reducing force.
Temperature influence – hot environment reduces pulling force. Too high temperature can permanently demagnetize the magnet.

Lifting capacity was assessed with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, however under parallel forces the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.

Safe handling of NdFeB magnets

Flammability

Fire warning: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this risks ignition.

Immense force

Handle magnets consciously. Their immense force can shock even experienced users. Stay alert and respect their power.

Keep away from children

Only for adults. Small elements pose a choking risk, leading to severe trauma. Store away from children and animals.

Precision electronics

GPS units and mobile phones are highly susceptible to magnetic fields. Close proximity with a strong magnet can decalibrate the internal compass in your phone.

Electronic devices

Device Safety: Strong magnets can damage data carriers and sensitive devices (heart implants, hearing aids, timepieces).

Do not overheat magnets

Do not overheat. NdFeB magnets are sensitive to heat. If you need operation above 80°C, inquire about HT versions (H, SH, UH).

Magnet fragility

Despite metallic appearance, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.

Physical harm

Mind your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!

Nickel allergy

A percentage of the population experience a hypersensitivity to Ni, which is the common plating for NdFeB magnets. Extended handling can result in an allergic reaction. It is best to wear safety gloves.

Pacemakers

Individuals with a heart stimulator must maintain an safe separation from magnets. The magnetism can interfere with the functioning of the implant.

Danger! More info about hazards in the article: Magnet Safety Guide.
