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. 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 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. The most effective home method is using adhesive tape, which we wrap around the dirt and peel off. 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. For the food and precision industry, we recommend the highest induction parameters.

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 as well as weaknesses of rare earth magnets.

Advantages

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

They have unchanged lifting capacity, and over nearly ten years their performance decreases symbolically – ~1% (according to theory),
Neodymium magnets are exceptionally resistant to magnetic field loss caused by external interference,
In other words, due to the metallic finish of gold, the element gains a professional look,
Magnets are distinguished by very high magnetic induction on the outer layer,
Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures reaching 230°C and above...
Possibility of custom forming as well as adapting to defined requirements,
Huge importance in high-tech industry – they serve a role in hard drives, electric motors, diagnostic systems, as well as complex engineering applications.
Thanks to their power density, small magnets offer high operating force, with minimal size,

Cons

Disadvantages of NdFeB magnets:

To avoid cracks under impact, we suggest using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
NdFeB magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in creating nuts and complicated forms in magnets, we propose using cover - magnetic mechanism.
Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that tiny parts of these magnets are able to disrupt the diagnostic process medical when they are in the body.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities

Lifting parameters

Highest magnetic holding force – what affects it?

Holding force of 0.00 kg is a measurement result performed under standard conditions:

using a base made of low-carbon steel, acting as a ideal flux conductor
possessing a massiveness of minimum 10 mm to ensure full flux closure
with an ideally smooth touching surface
with total lack of distance (no coatings)
for force acting at a right angle (in the magnet axis)
in temp. approx. 20°C

What influences lifting capacity in practice

In real-world applications, the actual lifting capacity results from many variables, presented from the most important:

Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
Direction of force – highest force is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Material composition – not every steel reacts the same. High carbon content weaken the interaction with the magnet.
Surface quality – the smoother and more polished the surface, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
Thermal conditions – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity was measured with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, however under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate reduces the load capacity.

Safety rules for work with neodymium magnets

Protective goggles

NdFeB magnets are ceramic materials, which means they are very brittle. Clashing of two magnets will cause them shattering into shards.

Allergic reactions

Certain individuals have a sensitization to nickel, which is the standard coating for NdFeB magnets. Extended handling can result in a rash. We strongly advise wear protective gloves.

Pacemakers

Individuals with a ICD have to maintain an safe separation from magnets. The magnetic field can stop the operation of the implant.

Safe operation

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

Crushing force

Danger of trauma: The attraction force is so great that it can cause hematomas, crushing, and even bone fractures. Use thick gloves.

GPS Danger

An intense magnetic field negatively affects the functioning of compasses in smartphones and GPS navigation. Maintain magnets close to a smartphone to avoid breaking the sensors.

Heat warning

Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will ruin its properties and strength.

Machining danger

Fire warning: Neodymium dust is explosive. Avoid machining magnets in home conditions as this risks ignition.

Cards and drives

Device Safety: Strong magnets can damage payment cards and delicate electronics (pacemakers, hearing aids, mechanical watches).

No play value

Strictly keep magnets away from children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are tragic.
