Holders with a hook are indispensable in large-format stores and warehouses for suspending advertisements (POS systems). In workshops and garages, they work perfectly for guiding cables or hanging work lighting.

The tip is fully demountable - you can unscrew the hook and screw in a bolt, eyelet, or other element in its place. 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. When mounting on a wall (vertically), the holding force is much lower due to shear force (the magnet may slide).

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.

For outdoor use (in rain), metal hangers may eventually develop a rusty coating over time. Metal elements can rust with constant contact with atmospheric moisture.

Strengths and weaknesses of rare earth magnets.

Strengths

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

Their power remains stable, and after approximately 10 years it drops only by ~1% (according to research),
They have excellent resistance to magnetic field loss due to opposing magnetic fields,
By using a reflective layer of gold, the element gains an modern look,
They feature high magnetic induction at the operating surface, which affects their effectiveness,
Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
Thanks to modularity in designing and the ability to customize to specific needs,
Huge importance in electronics industry – they are utilized in computer drives, electric motors, diagnostic systems, and complex engineering applications.
Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in compact constructions

Limitations

Disadvantages of neodymium magnets:

Brittleness is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a strong case, which not only protects them against impacts but also raises their durability
We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
Limited possibility of creating nuts in the magnet and complicated shapes - recommended is casing - magnet mounting.
Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, small components of these products are able to complicate diagnosis medical after entering the body.
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

Maximum lifting force for a neodymium magnet – what affects it?

Information about lifting capacity is the result of a measurement for optimal configuration, taking into account:

using a sheet made of low-carbon steel, functioning as a circuit closing element
possessing a massiveness of at least 10 mm to avoid saturation
with a plane free of scratches
under conditions of gap-free contact (metal-to-metal)
during detachment in a direction vertical to the mounting surface
in stable room temperature

Lifting capacity in practice – influencing factors

Please note that the application force may be lower influenced by the following factors, in order of importance:

Distance – existence of any layer (paint, dirt, air) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
Plate material – low-carbon steel gives the best results. Alloy steels reduce magnetic permeability and holding force.
Surface condition – ground elements ensure maximum contact, which improves field saturation. Uneven metal reduce efficiency.
Temperature – heating the magnet causes a temporary drop of induction. Check the maximum operating temperature for a given model.

Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under attempts to slide the magnet the holding force is lower. In addition, even a small distance between the magnet and the plate decreases the lifting capacity.

H&S for magnets

This is not a toy

Only for adults. Small elements can be swallowed, leading to serious injuries. Keep out of reach of children and animals.

Life threat

Individuals with a pacemaker must maintain an large gap from magnets. The magnetism can disrupt the functioning of the life-saving device.

Metal Allergy

A percentage of the population have a hypersensitivity to nickel, which is the typical protective layer for neodymium magnets. Extended handling may cause an allergic reaction. It is best to wear protective gloves.

Maximum temperature

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

Material brittleness

NdFeB magnets are ceramic materials, meaning they are prone to chipping. Clashing of two magnets leads to them shattering into small pieces.

Respect the power

Handle magnets consciously. Their huge power can shock even experienced users. Stay alert and do not underestimate their power.

Machining danger

Mechanical processing of NdFeB material poses a fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.

Hand protection

Big blocks can break fingers in a fraction of a second. Do not place your hand between two strong magnets.

Magnetic media

Do not bring magnets close to a purse, computer, or TV. The magnetism can permanently damage these devices and erase data from cards.

Threat to navigation

A strong magnetic field interferes with the operation of magnetometers in phones and GPS navigation. Maintain magnets near a device to avoid breaking the sensors.

Danger! Details about risks in the article: Safety of working with magnets.
