This product serves to effectively catch ferromagnetic contaminants from bulk and liquid products. It is commonly used for cleaning flour, sugar, plastic granules, as well as oils and coolants. Thanks to the use of strong neodymium magnets, the rod catches even metallic dust.

The construction relies on a sealed, welded stainless steel housing, polished smooth. The center is filled with NdFeB magnets and pole pieces, arranged to maximize the field on the tube surface. 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. The most effective home method is using adhesive tape, which we wrap around the dirt and peel off. 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 induction is necessary when contaminants are microscopic or weakly magnetic.

We can produce a rod of non-standard length with any mounting termination. 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 rare earth magnets.

Benefits

Besides their stability, neodymium magnets are valued for these benefits:

They retain full power for around ten years – the loss is just ~1% (according to analyses),
They possess excellent resistance to magnetism drop as a result of external fields,
The use of an refined layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
They feature high magnetic induction at the operating surface, which increases their power,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
Thanks to flexibility in constructing and the ability to adapt to specific needs,
Key role in innovative solutions – they find application in data components, electromotive mechanisms, medical equipment, also other advanced devices.
Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,

Weaknesses

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 and 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 and 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 recommend using waterproof magnets e.g. in rubber, plastic
Due to limitations in producing threads and complicated forms in magnets, we propose using a housing - magnetic holder.
Possible danger resulting from small fragments of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child safety. Furthermore, small elements of these magnets can be problematic in diagnostics medical in case of swallowing.
Due to expensive raw materials, their price is relatively high,

Lifting parameters

Magnetic strength at its maximum – what affects it?

The specified lifting capacity concerns the limit force, measured under laboratory conditions, namely:

on a plate made of mild steel, effectively closing the magnetic flux
whose thickness equals approx. 10 mm
characterized by even structure
with total lack of distance (no coatings)
for force applied at a right angle (in the magnet axis)
at temperature approx. 20 degrees Celsius

Practical lifting capacity: influencing factors

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

Gap (betwixt the magnet and the plate), since even a tiny distance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
Force direction – catalog parameter refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
Plate thickness – too thin steel does not accept the full field, causing part of the power to be lost into the air.
Material type – the best choice is high-permeability steel. Stainless steels may attract less.
Surface finish – ideal contact is possible only on smooth steel. Rough texture create air cushions, reducing force.
Operating temperature – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).

Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet and the plate lowers the load capacity.

Warnings

Keep away from electronics

Note: neodymium magnets produce a field that disrupts sensitive sensors. Keep a safe distance from your mobile, tablet, and navigation systems.

Crushing risk

Large magnets can crush fingers instantly. Never place your hand betwixt two attracting surfaces.

Keep away from children

These products are not toys. Accidental ingestion of several magnets may result in them pinching intestinal walls, which constitutes a critical condition and necessitates immediate surgery.

Risk of cracking

Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Impact of two magnets leads to them cracking into shards.

Machining danger

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

Heat warning

Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will ruin its properties and pulling force.

Implant safety

Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.

Safe operation

Handle with care. Neodymium magnets act from a long distance and snap with massive power, often faster than you can move away.

Cards and drives

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

Allergy Warning

Certain individuals suffer from a hypersensitivity to Ni, which is the typical protective layer for NdFeB magnets. Extended handling might lead to dermatitis. We recommend use protective gloves.
