They serve to create mobile suspension points without the need to drill holes in beams. 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). 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., 112.00 kg) refers to perpendicular (vertical) force when mounted on the ceiling. 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.

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.

Strengths

Besides their tremendous magnetic power, neodymium magnets offer the following advantages:

Their power is durable, and after around 10 years it decreases only by ~1% (according to research),
Magnets very well resist against loss of magnetization caused by ambient magnetic noise,
The use of an metallic coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
Magnets possess excellent magnetic induction on the active area,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
Possibility of precise forming and adapting to precise applications,
Universal use in electronics industry – they find application in hard drives, drive modules, diagnostic systems, also industrial machines.
Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Limitations

Disadvantages of NdFeB magnets:

Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a special holder, which not only secures them against impacts but also raises their durability
Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
Due to limitations in creating nuts and complex shapes in magnets, we propose using cover - magnetic holder.
Possible danger resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. It is also worth noting that small elements of these devices can complicate diagnosis medical when they are in the body.
With budget limitations the cost of neodymium magnets can be a barrier,

Holding force characteristics

Magnetic strength at its maximum – what contributes to it?

Information about lifting capacity is the result of a measurement for the most favorable conditions, including:

on a block made of structural steel, effectively closing the magnetic flux
with a cross-section no less than 10 mm
with a plane perfectly flat
without any clearance between the magnet and steel
for force applied at a right angle (pull-off, not shear)
at standard ambient temperature

Practical aspects of lifting capacity – factors

Real force is affected by working environment parameters, including (from most important):

Gap (betwixt the magnet and the metal), because even a very small clearance (e.g. 0.5 mm) results in a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
Material type – the best choice is high-permeability steel. Hardened steels may have worse magnetic properties.
Surface structure – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).

Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet and the plate reduces the holding force.

Safety rules for work with NdFeB magnets

Danger to pacemakers

People with a pacemaker must keep an safe separation from magnets. The magnetism can interfere with the functioning of the life-saving device.

Skin irritation risks

Some people experience a contact allergy to nickel, which is the typical protective layer for neodymium magnets. Frequent touching may cause an allergic reaction. We suggest wear protective gloves.

Crushing force

Protect your hands. Two large magnets will snap together instantly with a force of massive weight, crushing anything in their path. Be careful!

No play value

NdFeB magnets are not intended for children. Accidental ingestion of multiple magnets can lead to them pinching intestinal walls, which constitutes a direct threat to life and requires urgent medical intervention.

Dust explosion hazard

Machining of NdFeB material poses a fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.

Permanent damage

Watch the temperature. Heating the magnet above 80 degrees Celsius will ruin its properties and pulling force.

GPS Danger

Note: neodymium magnets produce a field that confuses precision electronics. Maintain a safe distance from your mobile, tablet, and navigation systems.

Risk of cracking

Despite metallic appearance, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.

Powerful field

Handle with care. Neodymium magnets attract from a distance and connect with massive power, often quicker than you can react.

Safe distance

Do not bring magnets close to a purse, computer, or TV. The magnetic field can destroy these devices and erase data from cards.
