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. 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 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. You can use compressed air or special non-magnetic strippers (rings). In industry, cover tubes (so-called Easy Clean system) are used, from which the magnetic insert slides out.

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. The rod end is strictly adapted to the fastening system in your device. We ensure fast realization of special orders and technical advice.

Strengths and weaknesses of neodymium magnets.

Strengths

Besides their tremendous strength, neodymium magnets offer the following advantages:

Their magnetic field is durable, and after around ten years it drops only by ~1% (according to research),
They are resistant to demagnetization induced by external field influence,
Thanks to the glossy finish, the coating of nickel, gold-plated, or silver gives an clean appearance,
The surface of neodymium magnets generates a concentrated magnetic field – this is one of their assets,
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...
Considering the ability of free molding and adaptation to custom requirements, NdFeB magnets can be produced in a wide range of shapes and sizes, which makes them more universal,
Wide application in innovative solutions – they are commonly used in HDD drives, electric motors, medical devices, and multitasking production systems.
Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which allows their use in miniature devices

Weaknesses

Cons of neodymium magnets and proposals for their use:

They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
We suggest cover - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complicated shapes.
Health risk related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child safety. Additionally, tiny parts of these products can disrupt the diagnostic process medical when they are in the body.
Due to neodymium price, their price is higher than average,

Pull force analysis

Maximum lifting capacity of the magnet – what it depends on?

Holding force of 0.00 kg is a theoretical maximum value conducted under specific, ideal conditions:

with the use of a yoke made of low-carbon steel, ensuring maximum field concentration
possessing a thickness of at least 10 mm to ensure full flux closure
with a plane perfectly flat
with total lack of distance (without coatings)
under perpendicular force direction (90-degree angle)
at temperature approx. 20 degrees Celsius

Practical aspects of lifting capacity – factors

It is worth knowing that the working load will differ depending on elements below, in order of importance:

Gap between surfaces – every millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
Steel grade – the best choice is high-permeability steel. Hardened steels may attract less.
Base smoothness – the smoother and more polished the surface, the better the adhesion and stronger the hold. Roughness creates an air distance.
Temperature influence – high temperature reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity was assessed using a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under parallel forces the load capacity is reduced by as much as 75%. Moreover, even a small distance between the magnet and the plate decreases the load capacity.

Precautions when working with neodymium magnets

Allergic reactions

Some people have a hypersensitivity to nickel, which is the common plating for NdFeB magnets. Extended handling may cause a rash. It is best to use safety gloves.

This is not a toy

Only for adults. Small elements pose a choking risk, causing serious injuries. Store out of reach of children and animals.

Phone sensors

A strong magnetic field disrupts the operation of magnetometers in smartphones and GPS navigation. Maintain magnets near a smartphone to avoid damaging the sensors.

Powerful field

Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.

Health Danger

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

Demagnetization risk

Standard neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. This process is irreversible.

Magnets are brittle

Despite the nickel coating, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.

Physical harm

Big blocks can smash fingers in a fraction of a second. Under no circumstances place your hand between two attracting surfaces.

Cards and drives

Avoid bringing magnets near a purse, computer, or TV. The magnetism can destroy these devices and wipe information from cards.

Mechanical processing

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