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.

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.

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.

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.

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.

Pros as well as cons of rare earth magnets.

Advantages

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

They retain full power for nearly 10 years – the drop is just ~1% (according to analyses),
Magnets perfectly defend themselves against loss of magnetization caused by external fields,
A magnet with a smooth nickel surface has better aesthetics,
Magnets possess impressive magnetic induction on the active area,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
Thanks to versatility in forming and the capacity to modify to unusual requirements,
Versatile presence in future technologies – they find application in mass storage devices, motor assemblies, precision medical tools, as well as technologically advanced constructions.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in miniature devices

Cons

Cons of neodymium magnets: weaknesses and usage proposals

They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
Limited ability of producing threads in the magnet and complicated forms - recommended is a housing - mounting mechanism.
Health risk related to microscopic parts of magnets are risky, if swallowed, which is particularly important in the context of child health protection. Furthermore, small elements of these devices can be problematic in diagnostics medical when they are in 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

Lifting parameters

Detachment force of the magnet in optimal conditions – what affects it?

Magnet power is the result of a measurement for optimal configuration, taking into account:

on a base made of structural steel, optimally conducting the magnetic flux
with a cross-section minimum 10 mm
with an polished touching surface
without the slightest insulating layer between the magnet and steel
during pulling in a direction perpendicular to the mounting surface
at conditions approx. 20°C

Magnet lifting force in use – key factors

In practice, the actual holding force is determined by many variables, ranked from crucial:

Clearance – existence of any layer (rust, tape, gap) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
Steel grade – the best choice is pure iron steel. Hardened steels may have worse magnetic properties.
Surface condition – smooth surfaces ensure maximum contact, which improves field saturation. Uneven metal reduce efficiency.
Thermal environment – temperature increase causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity was assessed using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under attempts to slide the magnet the holding force is lower. In addition, even a slight gap between the magnet and the plate reduces the load capacity.

Safe handling of neodymium magnets

Magnetic media

Equipment safety: Neodymium magnets can damage payment cards and delicate electronics (pacemakers, hearing aids, mechanical watches).

Health Danger

For implant holders: Powerful magnets affect electronics. Maintain at least 30 cm distance or request help to work with the magnets.

Do not overheat magnets

Avoid heat. Neodymium magnets are sensitive to heat. If you need operation above 80°C, inquire about special high-temperature series (H, SH, UH).

Keep away from children

Always keep magnets out of reach of children. Ingestion danger is high, and the effects of magnets connecting inside the body are life-threatening.

Crushing risk

Large magnets can crush fingers in a fraction of a second. Under no circumstances put your hand betwixt two strong magnets.

Fire risk

Powder created during cutting of magnets is combustible. Avoid drilling into magnets unless you are an expert.

Magnets are brittle

Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.

Immense force

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

GPS and phone interference

An intense magnetic field interferes with the functioning of magnetometers in smartphones and navigation systems. Maintain magnets near a smartphone to prevent damaging the sensors.

Allergy Warning

Medical facts indicate that the nickel plating (standard magnet coating) is a potent allergen. For allergy sufferers, refrain from direct skin contact and opt for versions in plastic housing.
