Pulling force


Magnetic Induction

Other offers

It is the "heart" of every magnetic filter used in industry for cleaning raw materials. It is mounted in chutes, hoppers, and pipelines to protect production machines from failure. High magnetic induction on the surface allows catching the finest iron particles.
The construction relies on a sealed, welded stainless steel housing, polished smooth. Inside there is a stack of strong neodymium magnets arranged in a special configuration (magnetic circuit). Thanks to this, the rod is durable, hygienic, and easy to keep clean.
Due to the high power of the magnet, direct removal of filings can be troublesome and time-consuming. We recommend sticking packing tape to the cluster of filings and tearing it off together with the contaminants. For easier operation, it is worth considering ordering a rod in a version with a cleaning sleeve.
The more Gauss, the smaller and more weakly magnetic particles will be effectively caught. The economical version (8kGs) handles large pieces of metal perfectly. High Power versions (~12000-14000 Gs) are necessary for catching metallic dust, oxides, and stainless steel after processing.
Yes, as a manufacturer, we make rods of any length and diameter (standard is dia 25mm and 32mm). The rod end is strictly adapted to the fastening system in your device. Contact us for a quote on a non-standard dimension.

Pros as well as cons of Nd2Fe14B magnets.

Benefits

Besides their magnetic performance, neodymium magnets are valued for these benefits:
  • They retain full power for almost 10 years – the drop is just ~1% (in theory),
  • Neodymium magnets prove to be highly resistant to magnetic field loss caused by external interference,
  • In other words, due to the aesthetic finish of gold, the element is aesthetically pleasing,
  • Neodymium magnets ensure maximum magnetic induction on a small surface, which allows for strong attraction,
  • Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
  • Thanks to modularity in designing and the ability to modify to complex applications,
  • Fundamental importance in future technologies – they serve a role in HDD drives, electric motors, precision medical tools, as well as multitasking production systems.
  • Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in compact constructions

Cons

Disadvantages of NdFeB magnets:
  • Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a special holder, which not only secures them against impacts but also raises their durability
  • 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.
  • They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
  • Limited possibility of producing nuts in the magnet and complicated forms - recommended is casing - mounting mechanism.
  • Health risk related to microscopic parts of magnets are risky, in case of ingestion, which becomes key in the context of child safety. Furthermore, small components of these magnets are able to be problematic in diagnostics medical in case of swallowing.
  • Due to neodymium price, their price is relatively high,

Holding force characteristics

Breakaway strength of the magnet in ideal conditionswhat affects it?

Holding force of 0.00 kg is a measurement result executed under specific, ideal conditions:
  • with the use of a sheet made of low-carbon steel, ensuring maximum field concentration
  • possessing a thickness of minimum 10 mm to avoid saturation
  • with a plane cleaned and smooth
  • with total lack of distance (without coatings)
  • for force acting at a right angle (pull-off, not shear)
  • at ambient temperature room level

Lifting capacity in practice – influencing factors

In real-world applications, the real power depends on a number of factors, ranked from crucial:
  • Gap between magnet and steel – every millimeter of distance (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
  • Direction of force – highest force is obtained only during perpendicular pulling. The force required to slide of the magnet along the plate is standardly several times lower (approx. 1/5 of the lifting capacity).
  • Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
  • Chemical composition of the base – low-carbon steel attracts best. Alloy steels lower magnetic permeability and lifting capacity.
  • Smoothness – ideal contact is possible only on smooth steel. Any scratches and bumps create air cushions, reducing force.
  • Thermal environment – temperature increase causes a temporary drop of force. Check the maximum operating temperature for a given model.

Lifting capacity was determined by applying a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate lowers the load capacity.

Safety rules for work with neodymium magnets
Safe distance

Powerful magnetic fields can corrupt files on credit cards, HDDs, and storage devices. Stay away of at least 10 cm.

Maximum temperature

Keep cool. NdFeB magnets are susceptible to heat. If you require operation above 80°C, look for special high-temperature series (H, SH, UH).

Allergy Warning

Certain individuals have a sensitization to nickel, which is the typical protective layer for neodymium magnets. Frequent touching might lead to skin redness. We recommend wear protective gloves.

Powerful field

Exercise caution. Neodymium magnets attract from a long distance and snap with huge force, often faster than you can react.

Bodily injuries

Mind your fingers. Two powerful magnets will join instantly with a force of massive weight, destroying everything in their path. Exercise extreme caution!

Impact on smartphones

GPS units and smartphones are extremely sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the sensors in your phone.

Material brittleness

Despite metallic appearance, the material is brittle and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.

Medical interference

People with a ICD have to maintain an absolute distance from magnets. The magnetism can disrupt the functioning of the implant.

Adults only

Strictly store magnets away from children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are tragic.

Combustion hazard

Fire hazard: Neodymium dust is highly flammable. Do not process magnets without safety gear as this risks ignition.
