A magnetic rod is the basic element of building grate separators and magnetic filters. 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. Inside there is a stack of strong neodymium magnets arranged in a special configuration (magnetic circuit). Such construction ensures full resistance to corrosion, water, oils, and acids.

Metal filings stick to the surface very strongly, so cleaning requires strength or cleverness. 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.

Magnetic induction measured in Gauss (Gs) determines the density of magnetic flux on the rod surface. The economical version (8kGs) handles large pieces of metal perfectly. 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. We ensure fast realization of special orders and technical advice.

Pros as well as cons of Nd₂Fe₁₄B magnets.

Strengths

Besides their magnetic performance, neodymium magnets are valued for these benefits:

They do not lose power, even during nearly 10 years – the decrease in power is only ~1% (according to tests),
They possess excellent resistance to weakening of magnetic properties as a result of opposing magnetic fields,
By using a reflective layer of gold, the element gains an professional look,
Magnets possess exceptionally strong magnetic induction on the outer layer,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
Thanks to freedom in shaping and the ability to adapt to individual projects,
Huge importance in future technologies – they find application in mass storage devices, electric drive systems, precision medical tools, also technologically advanced constructions.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which makes them useful in miniature devices

Disadvantages

Disadvantages of NdFeB magnets:

Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a special holder, which not only protects them against impacts but also raises their durability
When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength 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 - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
We recommend casing - magnetic holder, due to difficulties in producing threads inside the magnet and complicated shapes.
Possible danger resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child health protection. It is also worth noting that small components of these magnets can disrupt the diagnostic process medical when they are in the body.
With large orders the cost of neodymium magnets is a challenge,

Lifting parameters

Maximum magnetic pulling force – what contributes to it?

Information about lifting capacity was defined for ideal contact conditions, including:

using a sheet made of mild steel, functioning as a ideal flux conductor
with a cross-section no less than 10 mm
characterized by smoothness
under conditions of no distance (metal-to-metal)
for force acting at a right angle (in the magnet axis)
in temp. approx. 20°C

What influences lifting capacity in practice

Holding efficiency impacted by working environment parameters, mainly (from most important):

Air gap (betwixt the magnet and the plate), because even a tiny clearance (e.g. 0.5 mm) results in a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
Plate thickness – too thin plate does not accept the full field, causing part of the flux to be lost into the air.
Plate material – mild steel attracts best. Higher carbon content decrease magnetic properties and holding force.
Surface condition – ground elements guarantee perfect abutment, which increases field saturation. Uneven metal reduce efficiency.
Temperature – temperature increase causes a temporary drop of force. Check 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 shearing force the load capacity is reduced by as much as 75%. Additionally, even a minimal clearance between the magnet and the plate decreases the lifting capacity.

Warnings

Avoid contact if allergic

Some people suffer from a contact allergy to nickel, which is the standard coating for neodymium magnets. Frequent touching can result in a rash. It is best to wear protective gloves.

Maximum temperature

Regular neodymium magnets (grade N) lose power when the temperature exceeds 80°C. This process is irreversible.

Conscious usage

Use magnets consciously. Their immense force can surprise even professionals. Be vigilant and respect their force.

Fire risk

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

Magnetic media

Very strong magnetic fields can destroy records on payment cards, HDDs, and storage devices. Maintain a gap of at least 10 cm.

GPS and phone interference

Be aware: neodymium magnets produce a field that disrupts precision electronics. Keep a safe distance from your phone, tablet, and GPS.

Hand protection

Big blocks can crush fingers in a fraction of a second. Do not place your hand between two strong magnets.

Implant safety

For implant holders: Powerful magnets affect electronics. Maintain minimum 30 cm distance or request help to handle the magnets.

Fragile material

Beware of splinters. Magnets can explode upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.

Danger to the youngest

NdFeB magnets are not intended for children. Accidental ingestion of several magnets can lead to them pinching intestinal walls, which poses a direct threat to life and requires urgent medical intervention.
