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. 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 filings stick to the surface very strongly, so cleaning requires strength or cleverness. We recommend sticking packing tape to the cluster of filings and tearing it off together with the contaminants. 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. 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 can produce a rod of non-standard length with any mounting termination. You can choose a mounting method consistent with your technical design. Contact us for a quote on a non-standard dimension.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Benefits

Besides their tremendous magnetic power, neodymium magnets offer the following advantages:

Their strength is durable, and after around ten years it drops only by ~1% (theoretically),
Neodymium magnets are remarkably resistant to demagnetization caused by external field sources,
In other words, due to the metallic layer of silver, the element becomes visually attractive,
Neodymium magnets create maximum magnetic induction on a small surface, which ensures high operational effectiveness,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
Possibility of detailed creating as well as modifying to individual requirements,
Universal use in electronics industry – they are utilized in data components, motor assemblies, precision medical tools, as well as multitasking production systems.
Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Limitations

Disadvantages of NdFeB magnets:

To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
Due to limitations in realizing nuts and complicated forms in magnets, we recommend using a housing - magnetic holder.
Health risk resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these magnets can be problematic in diagnostics medical in case of swallowing.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Lifting parameters

Magnetic strength at its maximum – what affects it?

The declared magnet strength concerns the peak performance, obtained under optimal environment, specifically:

with the application of a yoke made of special test steel, guaranteeing maximum field concentration
whose transverse dimension reaches at least 10 mm
characterized by lack of roughness
with total lack of distance (no impurities)
during pulling in a direction perpendicular to the plane
at standard ambient temperature

Lifting capacity in practice – influencing factors

It is worth knowing that the magnet holding will differ depending on the following factors, starting with the most relevant:

Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
Load vector – highest force is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the surface is standardly many times smaller (approx. 1/5 of the lifting capacity).
Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
Metal type – not every steel reacts the same. Alloy additives weaken the interaction with the magnet.
Smoothness – ideal contact is obtained only on smooth steel. Rough texture create air cushions, weakening the magnet.
Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).

Lifting capacity was measured with the use of a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.

Precautions when working with neodymium magnets

Bone fractures

Mind your fingers. Two large magnets will join immediately with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!

Avoid contact if allergic

Medical facts indicate that nickel (standard magnet coating) is a potent allergen. If you have an allergy, avoid touching magnets with bare hands and choose coated magnets.

Impact on smartphones

A strong magnetic field interferes with the functioning of magnetometers in phones and navigation systems. Keep magnets near a device to avoid damaging the sensors.

Heat warning

Control the heat. Heating the magnet to high heat will permanently weaken its properties and pulling force.

Conscious usage

Be careful. Neodymium magnets act from a distance and connect with huge force, often faster than you can react.

Danger to pacemakers

Individuals with a heart stimulator must keep an absolute distance from magnets. The magnetism can interfere with the functioning of the implant.

Data carriers

Avoid bringing magnets near a purse, laptop, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.

Risk of cracking

Watch out for shards. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Wear goggles.

Adults only

Product intended for adults. Small elements pose a choking risk, causing severe trauma. Keep away from kids and pets.

Dust is flammable

Combustion risk: Rare earth powder is highly flammable. Do not process magnets in home conditions as this may cause fire.

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