Field Strength

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., 38.00 kg) refers to perpendicular (vertical) force when mounted on the ceiling. For heavy ceiling ads or tools, we recommend choosing a magnet with a considerable power reserve.
The steel housing (cup) shields the magnetic field, directing all its power downwards, onto the contact surface. The housing ensures mechanical durability, which is important in industrial and assembly conditions.
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.

Advantages as well as disadvantages of Nd2Fe14B magnets.

Advantages

In addition to their magnetic capacity, neodymium magnets provide the following advantages:
  • Their strength is maintained, and after approximately 10 years it decreases only by ~1% (theoretically),
  • They do not lose their magnetic properties even under strong external field,
  • A magnet with a metallic silver surface looks better,
  • Neodymium magnets ensure maximum magnetic induction on a small surface, which increases force concentration,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
  • Possibility of exact modeling and adjusting to defined needs,
  • Key role in future technologies – they serve a role in mass storage devices, brushless drives, precision medical tools, as well as technologically advanced constructions.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Limitations

Drawbacks and weaknesses of neodymium magnets and ways of using them
  • Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a strong case, which not only secures them against impacts but also raises their durability
  • Neodymium magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
  • Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
  • Limited possibility of producing threads in the magnet and complicated forms - recommended is cover - mounting mechanism.
  • Potential hazard to health – tiny shards of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small elements of these products are able to complicate diagnosis medical after entering the body.
  • Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

Breakaway strength of the magnet in ideal conditionswhat contributes to it?

Holding force of 38.00 kg is a theoretical maximum value conducted under the following configuration:
  • with the use of a yoke made of special test steel, guaranteeing maximum field concentration
  • possessing a thickness of minimum 10 mm to avoid saturation
  • with an ground contact surface
  • under conditions of gap-free contact (surface-to-surface)
  • during pulling in a direction vertical to the mounting surface
  • in temp. approx. 20°C

Magnet lifting force in use – key factors

It is worth knowing that the application force may be lower depending on elements below, starting with the most relevant:
  • Clearance – existence of any layer (rust, dirt, air) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
  • Direction of force – highest force is reached only during pulling at a 90° angle. The shear force of the magnet along the plate is standardly several times lower (approx. 1/5 of the lifting capacity).
  • Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
  • Metal type – not every steel reacts the same. Alloy additives weaken the attraction effect.
  • Surface quality – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
  • Temperature influence – hot environment reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.

Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate reduces the holding force.

Warnings
Swallowing risk

Absolutely store magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are fatal.

Warning for heart patients

Warning for patients: Strong magnetic fields affect medical devices. Keep minimum 30 cm distance or ask another person to handle the magnets.

Protective goggles

Watch out for shards. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.

Electronic devices

Intense magnetic fields can erase data on payment cards, hard drives, and storage devices. Maintain a gap of at least 10 cm.

Threat to navigation

Navigation devices and smartphones are highly sensitive to magnetism. Close proximity with a strong magnet can ruin the sensors in your phone.

Powerful field

Exercise caution. Rare earth magnets attract from a distance and connect with massive power, often faster than you can react.

Nickel coating and allergies

Nickel alert: The Ni-Cu-Ni coating consists of nickel. If redness occurs, immediately stop handling magnets and use protective gear.

Power loss in heat

Regular neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. This process is irreversible.

Do not drill into magnets

Dust produced during cutting of magnets is flammable. Do not drill into magnets unless you are an expert.

Bone fractures

Mind your fingers. Two powerful magnets will snap together instantly with a force of massive weight, destroying everything in their path. Be careful!
