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. Thanks to the use of strong neodymium magnets, the rod catches even metallic dust.
The outer layer is hygienic acid-resistant steel, approved for food contact. The core is a precise magnetic system generating high induction (Gauss). Thanks to this, the rod is durable, hygienic, and easy to keep clean.
Metal contaminants are strongly attracted, so removing them with a bare hand or glove can be difficult. You can use compressed air or special non-magnetic strippers (rings). For easier operation, it is worth considering ordering a rod in a version with a cleaning sleeve.
The Gauss value tells us how effectively and deeply the magnet will catch contaminants. The economical version (8kGs) handles large pieces of metal perfectly. For the food and precision industry, we recommend the highest induction parameters.
We can produce a rod of non-standard length with any mounting termination. You can choose a mounting method consistent with your technical design. We ensure fast realization of special orders and technical advice.

Pros and cons of Nd2Fe14B magnets.

Advantages

Besides their stability, neodymium magnets are valued for these benefits:
  • They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
  • They are resistant to demagnetization induced by external disturbances,
  • The use of an elegant coating of noble metals (nickel, gold, silver) causes the element to present itself better,
  • The surface of neodymium magnets generates a maximum magnetic field – this is a key feature,
  • Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures reaching 230°C and above...
  • Thanks to freedom in shaping and the capacity to customize to client solutions,
  • Universal use in advanced technology sectors – they are commonly used in mass storage devices, electric drive systems, medical devices, as well as industrial machines.
  • Compactness – despite small sizes they generate large force, making them ideal for precision applications

Disadvantages

Disadvantages of neodymium magnets:
  • They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
  • When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
  • Limited ability of creating threads in the magnet and complicated shapes - preferred is a housing - magnet mounting.
  • Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Furthermore, tiny parts of these products are able to be problematic in diagnostics medical when they are in the body.
  • With large orders the cost of neodymium magnets is economically unviable,

Holding force characteristics

Magnetic strength at its maximum – what it depends on?

The load parameter shown concerns the maximum value, obtained under optimal environment, meaning:
  • with the use of a sheet made of special test steel, ensuring full magnetic saturation
  • possessing a thickness of min. 10 mm to avoid saturation
  • with a surface free of scratches
  • under conditions of ideal adhesion (metal-to-metal)
  • under vertical application of breakaway force (90-degree angle)
  • in neutral thermal conditions

Practical aspects of lifting capacity – factors

Effective lifting capacity is affected by specific conditions, mainly (from most important):
  • Distance – the presence of foreign body (paint, tape, air) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
  • Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
  • Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
  • Chemical composition of the base – low-carbon steel attracts best. Alloy steels decrease magnetic properties and holding force.
  • Surface quality – the more even the surface, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
  • Thermal environment – heating the magnet causes a temporary drop of force. Check the maximum operating temperature for a given model.

Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet and the plate reduces the load capacity.

Warnings
Heat warning

Standard neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. The loss of strength is permanent.

Danger to the youngest

Always keep magnets out of reach of children. Ingestion danger is high, and the effects of magnets clamping inside the body are tragic.

Sensitization to coating

Medical facts indicate that the nickel plating (the usual finish) is a strong allergen. If your skin reacts to metals, avoid touching magnets with bare hands or select encased magnets.

Fire warning

Dust produced during cutting of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.

Protective goggles

Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.

Threat to electronics

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

Hand protection

Big blocks can smash fingers in a fraction of a second. Under no circumstances place your hand between two attracting surfaces.

Respect the power

Handle magnets consciously. Their powerful strength can surprise even professionals. Be vigilant and respect their force.

GPS and phone interference

Remember: rare earth magnets generate a field that disrupts sensitive sensors. Keep a safe distance from your mobile, device, and GPS.

ICD Warning

Medical warning: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.
