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 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. 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. Standard rods (~8000 Gs) are sufficient for catching screws, nails, and steel shavings. For the food and precision industry, we recommend the highest induction parameters.

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 rare earth magnets.

Pros

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

They have constant strength, and over around ten years their attraction force decreases symbolically – ~1% (according to theory),
Magnets effectively resist against loss of magnetization caused by ambient magnetic noise,
By applying a decorative layer of gold, the element acquires an elegant look,
Neodymium magnets ensure maximum magnetic induction on a small surface, which allows for strong attraction,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
Due to the possibility of precise forming and customization to individualized projects, NdFeB magnets can be produced in a variety of forms and dimensions, which makes them more universal,
Key role in advanced technology sectors – they are used in mass storage devices, electric drive systems, advanced medical instruments, as well as complex engineering applications.
Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Cons

Disadvantages of neodymium magnets:

At very strong impacts they can crack, therefore we recommend placing them in special holders. 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
Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
Limited possibility of producing threads in the magnet and complicated forms - recommended is cover - mounting mechanism.
Health risk to health – tiny shards of magnets are risky, in case of ingestion, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these products can be problematic in diagnostics medical after entering the body.
With large orders the cost of neodymium magnets is a challenge,

Pull force analysis

Detachment force of the magnet in optimal conditions – what it depends on?

Magnet power was defined for optimal configuration, including:

with the use of a yoke made of special test steel, ensuring maximum field concentration
with a cross-section minimum 10 mm
with an polished contact surface
under conditions of ideal adhesion (metal-to-metal)
for force applied at a right angle (pull-off, not shear)
at standard ambient temperature

Lifting capacity in practice – influencing factors

Effective lifting capacity is affected by specific conditions, including (from most important):

Clearance – the presence of any layer (rust, tape, air) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
Steel thickness – too thin plate causes magnetic saturation, causing part of the flux to be escaped to the other side.
Chemical composition of the base – low-carbon steel attracts best. Higher carbon content decrease magnetic properties and lifting capacity.
Surface condition – smooth surfaces ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
Operating temperature – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and in frost gain strength (up to a certain limit).

Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate reduces the lifting capacity.

Safety rules for work with neodymium magnets

Threat to navigation

Navigation devices and smartphones are highly sensitive to magnetism. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.

Material brittleness

NdFeB magnets are ceramic materials, which means they are fragile like glass. Impact of two magnets leads to them shattering into shards.

Swallowing risk

NdFeB magnets are not intended for children. Accidental ingestion of several magnets may result in them attracting across intestines, which poses a severe health hazard and necessitates immediate surgery.

Avoid contact if allergic

Studies show that the nickel plating (standard magnet coating) is a common allergen. For allergy sufferers, avoid direct skin contact and opt for coated magnets.

Heat warning

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

Dust explosion hazard

Combustion risk: Rare earth powder is explosive. Avoid machining magnets in home conditions as this may cause fire.

Safe operation

Before starting, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.

Hand protection

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

Medical implants

Health Alert: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.

Cards and drives

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