This product serves to effectively catch ferromagnetic contaminants from bulk and liquid products. 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 center is filled with NdFeB magnets and pole pieces, arranged to maximize the field on the tube surface. Such construction ensures full resistance to corrosion, water, oils, and acids.
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. In industry, cover tubes (so-called Easy Clean system) are used, from which the magnetic insert slides out.
The Gauss value tells us how effectively and deeply the magnet will catch contaminants. For basic machine protection against pieces of iron, standard power is sufficient. High Power versions (~12000-14000 Gs) are necessary for catching metallic dust, oxides, and stainless steel after processing.
We fulfill individual orders for bars perfectly matched to your machine or separator. The rod end is strictly adapted to the fastening system in your device. 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 do not lose strength, even after nearly ten years – the drop in strength is only ~1% (theoretically),
  • Magnets effectively defend themselves against loss of magnetization caused by ambient magnetic noise,
  • Thanks to the reflective finish, the surface of nickel, gold-plated, or silver-plated gives an aesthetic appearance,
  • Magnetic induction on the top side of the magnet is very high,
  • 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...
  • Thanks to versatility in forming and the capacity to customize to unusual requirements,
  • Significant place in electronics industry – they find application in hard drives, brushless drives, advanced medical instruments, and industrial machines.
  • Thanks to concentrated force, small magnets offer high operating force, in miniature format,

Cons

Cons of neodymium magnets: tips and applications.
  • To avoid cracks under impact, we recommend using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
  • We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
  • Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
  • Limited possibility of producing threads in the magnet and complex shapes - recommended is casing - mounting mechanism.
  • Health risk resulting from small fragments of magnets pose a threat, in case of ingestion, which becomes key in the context of child health protection. It is also worth noting that small components of these devices can be problematic in diagnostics medical when they are in the body.
  • With budget limitations the cost of neodymium magnets is a challenge,

Holding force characteristics

Magnetic strength at its maximum – what contributes to it?

The force parameter is a result of laboratory testing conducted under standard conditions:
  • on a base made of mild steel, effectively closing the magnetic flux
  • with a thickness no less than 10 mm
  • with a plane cleaned and smooth
  • under conditions of ideal adhesion (metal-to-metal)
  • during detachment in a direction vertical to the mounting surface
  • at standard ambient temperature

Determinants of practical lifting force of a magnet

Real force impacted by working environment parameters, mainly (from priority):
  • Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
  • Load vector – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the surface is typically several times lower (approx. 1/5 of the lifting capacity).
  • Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
  • Steel type – low-carbon steel gives the best results. Higher carbon content reduce magnetic properties and holding force.
  • Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
  • Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).

Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the holding force is lower. In addition, even a slight gap between the magnet and the plate reduces the holding force.

Safety rules for work with neodymium magnets
Fire warning

Drilling and cutting of neodymium magnets poses a fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.

Operating temperature

Do not overheat. Neodymium magnets are sensitive to heat. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).

Protect data

Do not bring magnets near a purse, computer, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.

Phone sensors

Remember: rare earth magnets generate a field that confuses sensitive sensors. Maintain a separation from your phone, tablet, and GPS.

Magnet fragility

Watch out for shards. Magnets can explode upon violent connection, ejecting shards into the air. Eye protection is mandatory.

No play value

NdFeB magnets are not toys. Accidental ingestion of a few magnets can lead to them connecting inside the digestive tract, which poses a critical condition and requires immediate surgery.

Powerful field

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

Finger safety

Danger of trauma: The pulling power is so great that it can result in blood blisters, crushing, and broken bones. Protective gloves are recommended.

Medical interference

Health Alert: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.

Allergy Warning

Studies show that nickel (the usual finish) is a strong allergen. If your skin reacts to metals, prevent direct skin contact and select versions in plastic housing.

Danger! More info about hazards in the article: Magnet Safety Guide.
