A hook magnet is an ideal solution for quick mounting of banners, signs, and markings on steel ceiling structures. 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.
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. Additionally, steel protects the brittle magnet from cracking upon hitting the ceiling or beam.
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.

Strengths and weaknesses of neodymium magnets.

Benefits
Apart from their consistent magnetism, neodymium magnets have these key benefits:
  • They virtually do not lose strength, because even after ten years the performance loss is only ~1% (according to literature),
  • They are resistant to demagnetization induced by presence of other magnetic fields,
  • A magnet with a shiny silver surface is more attractive,
  • They show high magnetic induction at the operating surface, which improves attraction properties,
  • Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
  • Thanks to the possibility of flexible shaping and adaptation to custom needs, magnetic components can be manufactured in a wide range of geometric configurations, which makes them more universal,
  • Fundamental importance in electronics industry – they serve a role in magnetic memories, brushless drives, precision medical tools, also technologically advanced constructions.
  • Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
Characteristics of disadvantages of neodymium magnets: tips and applications.
  • At strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • Neodymium magnets decrease their power 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
  • They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • We recommend cover - magnetic mechanism, due to difficulties in producing threads inside the magnet and complicated forms.
  • Possible danger to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the context of child health protection. Furthermore, small elements of these devices can disrupt the diagnostic process medical in case of swallowing.
  • Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

Magnetic strength at its maximum – what contributes to it?
The declared magnet strength refers to the maximum value, obtained under ideal test conditions, specifically:
  • using a base made of high-permeability steel, serving as a magnetic yoke
  • with a cross-section minimum 10 mm
  • with a surface perfectly flat
  • with total lack of distance (without paint)
  • for force acting at a right angle (in the magnet axis)
  • at ambient temperature approx. 20 degrees Celsius
Lifting capacity in real conditions – factors
During everyday use, the real power is determined by many variables, listed from the most important:
  • Space between magnet and steel – every millimeter of distance (caused e.g. by varnish or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
  • Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
  • Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
  • Steel grade – the best choice is high-permeability steel. Cast iron may generate lower lifting capacity.
  • Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
  • Temperature – heating the magnet results in weakening of induction. Check the maximum operating temperature for a given model.

Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the holding force is lower. Moreover, even a small distance between the magnet and the plate lowers the load capacity.

Safe handling of neodymium magnets
Do not overheat magnets

Monitor thermal conditions. Exposing the magnet to high heat will destroy its properties and strength.

Do not underestimate power

Before starting, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.

Danger to the youngest

Only for adults. Tiny parts pose a choking risk, causing severe trauma. Keep away from children and animals.

Keep away from electronics

Be aware: neodymium magnets generate a field that interferes with sensitive sensors. Keep a safe distance from your phone, device, and navigation systems.

Safe distance

Do not bring magnets close to a purse, computer, or screen. The magnetism can permanently damage these devices and wipe information from cards.

Do not drill into magnets

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

Allergic reactions

It is widely known that nickel (standard magnet coating) is a common allergen. If you have an allergy, prevent direct skin contact or select versions in plastic housing.

Risk of cracking

Watch out for shards. Magnets can fracture upon violent connection, ejecting shards into the air. Wear goggles.

Pacemakers

Medical warning: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.

Bone fractures

Protect your hands. Two powerful magnets will snap together immediately with a force of massive weight, crushing anything in their path. Exercise extreme caution!
