This product serves to effectively catch ferromagnetic contaminants from bulk and liquid products. Its task is separation (separation) of metal filings from the transported material. High magnetic induction on the surface allows catching the finest iron particles.

The construction relies on a sealed, welded stainless steel housing, polished smooth. 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). In industry, cover tubes (so-called Easy Clean system) are used, from which the magnetic insert slides out.

The more Gauss, the smaller and more weakly magnetic particles will be effectively caught. 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.

Yes, as a manufacturer, we make rods of any length and diameter (standard is dia 25mm and 32mm). We offer various tip options: threaded holes (e.g., M8, M10), protruding screws, flat pivots, mills, or handles. Contact us for a quote on a non-standard dimension.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Strengths

Apart from their superior magnetic energy, neodymium magnets have these key benefits:

They do not lose strength, even over around ten years – the reduction in strength is only ~1% (theoretically),
They retain their magnetic properties even under external field action,
By applying a lustrous coating of silver, the element has an elegant look,
Neodymium magnets ensure maximum magnetic induction on a contact point, which ensures high operational effectiveness,
Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures reaching 230°C and above...
Thanks to modularity in constructing and the ability to modify to individual projects,
Universal use in modern industrial fields – they are commonly used in magnetic memories, electromotive mechanisms, medical equipment, as well as industrial machines.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Limitations

Disadvantages of NdFeB magnets:

At very strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
When exposed to high temperature, neodymium magnets suffer a drop in power. 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
Magnets exposed to a humid environment can rust. Therefore while using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in producing threads and complex shapes in magnets, we recommend using cover - magnetic holder.
Possible danger related to microscopic parts of magnets are risky, in case of ingestion, which becomes key in the context of child health protection. It is also worth noting that small components of these magnets can be problematic in diagnostics medical in case of swallowing.
Due to complex production process, their price is higher than average,

Holding force characteristics

Maximum lifting force for a neodymium magnet – what it depends on?

Breakaway force was determined for the most favorable conditions, taking into account:

with the contact of a sheet made of low-carbon steel, ensuring full magnetic saturation
possessing a massiveness of minimum 10 mm to ensure full flux closure
characterized by smoothness
under conditions of no distance (surface-to-surface)
for force acting at a right angle (in the magnet axis)
in temp. approx. 20°C

Determinants of lifting force in real conditions

In practice, the real power results from several key aspects, listed from most significant:

Air gap (betwixt the magnet and the plate), since even a microscopic clearance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to paint, corrosion or debris).
Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of nominal force).
Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
Material composition – different alloys reacts the same. Alloy additives worsen the interaction with the magnet.
Surface finish – ideal contact is obtained only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
Thermal environment – temperature increase results in weakening of induction. It is worth remembering the thermal limit for a given model.

Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under parallel forces the holding force is lower. Moreover, even a small distance between the magnet and the plate decreases the load capacity.

Warnings

Dust is flammable

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

Implant safety

People with a heart stimulator must maintain an large gap from magnets. The magnetic field can disrupt the operation of the life-saving device.

Danger to the youngest

Neodymium magnets are not intended for children. Swallowing several magnets may result in them pinching intestinal walls, which constitutes a critical condition and necessitates immediate surgery.

Threat to electronics

Device Safety: Neodymium magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, timepieces).

Shattering risk

NdFeB magnets are ceramic materials, which means they are fragile like glass. Collision of two magnets will cause them shattering into small pieces.

Avoid contact if allergic

Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If redness occurs, cease handling magnets and use protective gear.

Keep away from electronics

Remember: rare earth magnets produce a field that confuses precision electronics. Maintain a separation from your mobile, tablet, and GPS.

Thermal limits

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

Pinching danger

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

Powerful field

Handle with care. Rare earth magnets attract from a long distance and snap with huge force, often quicker than you can move away.

Danger! More info about hazards in the article: Safety of working with magnets.
