They serve to create mobile suspension points without the need to drill holes in beams. It is a universal hanger that you can move to another place at any time without a trace.

Yes, the hook is an element screwed into a bushing with a metric thread (e.g., M4, M5, M6 - check description). 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. 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. A bare magnet could crack upon sudden application to metal, and the holder is resistant to this.

In the bathroom or kitchen, they will work perfectly, provided they are not directly splashed with water. If you are looking for an outdoor hanger, choose a model in rubberized or plastic housing, which is tight.

Pros and cons of rare earth magnets.

Pros

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

They have stable power, and over nearly ten years their attraction force decreases symbolically – ~1% (in testing),
They feature excellent resistance to magnetism drop due to external fields,
In other words, due to the glossy surface of silver, the element is aesthetically pleasing,
Neodymium magnets deliver maximum magnetic induction on a their surface, which increases force concentration,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
Thanks to modularity in designing and the capacity to modify to client solutions,
Key role in modern industrial fields – they are used in hard drives, electric drive systems, medical equipment, also technologically advanced constructions.
Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Weaknesses

Disadvantages of NdFeB magnets:

To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
Magnets exposed to a humid environment can rust. Therefore while using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
Limited ability of producing nuts in the magnet and complex forms - recommended is a housing - magnetic holder.
Possible danger to health – tiny shards of magnets pose a threat, in case of ingestion, which becomes key in the context of child safety. It is also worth noting that small components of these products can be problematic in diagnostics medical when they are in the body.
Due to expensive raw materials, their price is higher than average,

Holding force characteristics

Breakaway strength of the magnet in ideal conditions – what affects it?

The declared magnet strength refers to the limit force, recorded under ideal test conditions, meaning:

with the contact of a yoke made of low-carbon steel, ensuring maximum field concentration
with a cross-section minimum 10 mm
characterized by even structure
under conditions of gap-free contact (surface-to-surface)
under vertical application of breakaway force (90-degree angle)
at ambient temperature room level

Magnet lifting force in use – key factors

Effective lifting capacity is influenced by specific conditions, such as (from most important):

Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
Force direction – catalog parameter refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
Material type – the best choice is high-permeability steel. Stainless steels may generate lower lifting capacity.
Surface quality – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Roughness creates an air distance.
Temperature influence – hot environment reduces magnetic field. Too high temperature can permanently demagnetize the magnet.

Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, in contrast under shearing force the load capacity is reduced by as much as 5 times. Additionally, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.

Safety rules for work with neodymium magnets

Do not overheat magnets

Regular neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. Damage is permanent.

Pacemakers

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

Dust is flammable

Powder generated during grinding of magnets is combustible. Avoid drilling into magnets unless you are an expert.

Handling guide

Before starting, read the rules. Sudden snapping can destroy the magnet or injure your hand. Be predictive.

Product not for children

Strictly store magnets away from children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are tragic.

Shattering risk

NdFeB magnets are sintered ceramics, which means they are fragile like glass. Clashing of two magnets leads to them cracking into shards.

Keep away from electronics

Note: neodymium magnets produce a field that disrupts sensitive sensors. Maintain a safe distance from your phone, device, and navigation systems.

Keep away from computers

Very strong magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Maintain a gap of min. 10 cm.

Bodily injuries

Protect your hands. Two powerful magnets will snap together immediately with a force of several hundred kilograms, crushing everything in their path. Be careful!

Skin irritation risks

It is widely known that the nickel plating (standard magnet coating) is a common allergen. For allergy sufferers, prevent direct skin contact and choose coated magnets.
