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). 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. When mounting on a wall (vertically), the holding force is much lower due to shear force (the magnet may slide).

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.

In the bathroom or kitchen, they will work perfectly, provided they are not directly splashed with water. Metal elements can rust with constant contact with atmospheric moisture.

Advantages as well as disadvantages of neodymium magnets.

Benefits

Besides their magnetic performance, neodymium magnets are valued for these benefits:

They retain full power for nearly ten years – the loss is just ~1% (in theory),
They do not lose their magnetic properties even under close interference source,
In other words, due to the glossy finish of nickel, the element is aesthetically pleasing,
They show high magnetic induction at the operating surface, making them more effective,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
In view of the potential of free shaping and customization to individualized requirements, NdFeB magnets can be created in a wide range of forms and dimensions, which increases their versatility,
Wide application in high-tech industry – they are commonly used in computer drives, motor assemblies, diagnostic systems, and multitasking production systems.
Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in miniature devices

Cons

Disadvantages of NdFeB magnets:

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a strong case, which not only secures them against impacts but also increases their durability
Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability 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 those in rubber or plastics, which prevent oxidation and corrosion.
Due to limitations in producing nuts and complex forms in magnets, we recommend using casing - magnetic mount.
Health risk related to microscopic parts of magnets are risky, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Furthermore, small components of these magnets can disrupt the diagnostic process medical after entering the body.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities

Pull force analysis

Maximum holding power of the magnet – what affects it?

The load parameter shown represents the maximum value, obtained under laboratory conditions, meaning:

using a plate made of mild steel, acting as a ideal flux conductor
possessing a thickness of min. 10 mm to avoid saturation
with a surface perfectly flat
under conditions of gap-free contact (metal-to-metal)
for force acting at a right angle (in the magnet axis)
at conditions approx. 20°C

Determinants of practical lifting force of a magnet

Please note that the working load will differ influenced by the following factors, in order of importance:

Distance – the presence of foreign body (paint, tape, gap) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
Loading method – catalog parameter refers to pulling vertically. When applying parallel force, the magnet holds much less (typically approx. 20-30% of maximum force).
Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
Plate material – low-carbon steel attracts best. Higher carbon content reduce magnetic properties and holding force.
Plate texture – smooth surfaces guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
Temperature – temperature increase results in weakening of force. Check the maximum operating temperature for a given model.

Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under parallel forces the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate decreases the load capacity.

Safety rules for work with neodymium magnets

Crushing force

Big blocks can break fingers in a fraction of a second. Under no circumstances place your hand between two attracting surfaces.

Powerful field

Use magnets with awareness. Their huge power can surprise even experienced users. Be vigilant and do not underestimate their power.

Flammability

Fire warning: Rare earth powder is explosive. Avoid machining magnets in home conditions as this may cause fire.

Do not overheat magnets

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

Threat to navigation

Remember: neodymium magnets generate a field that confuses precision electronics. Keep a separation from your phone, device, and navigation systems.

Allergy Warning

Some people have a sensitization to nickel, which is the common plating for neodymium magnets. Frequent touching might lead to an allergic reaction. It is best to wear protective gloves.

Protect data

Avoid bringing magnets near a purse, laptop, or TV. The magnetism can permanently damage these devices and erase data from cards.

Risk of cracking

NdFeB magnets are ceramic materials, which means they are very brittle. Impact of two magnets leads to them shattering into shards.

Product not for children

Absolutely keep magnets out of reach of children. Choking hazard is significant, and the effects of magnets connecting inside the body are life-threatening.

ICD Warning

Warning for patients: Powerful magnets disrupt electronics. Maintain at least 30 cm distance or request help to handle the magnets.
