It is the "heart" of every magnetic filter used in industry for cleaning raw materials. 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 construction relies on a sealed, welded stainless steel housing, polished smooth. 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.

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. In industry, cover tubes (so-called Easy Clean system) are used, from which the magnetic insert slides out.

The more Gauss, the smaller and more weakly magnetic particles will be effectively caught. 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 fulfill individual orders for bars perfectly matched to your machine or separator. 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 and cons of neodymium magnets.

Benefits

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

They do not lose magnetism, even over approximately ten years – the reduction in lifting capacity is only ~1% (based on measurements),
They are extremely resistant to demagnetization induced by presence of other magnetic fields,
Thanks to the reflective finish, the layer of nickel, gold-plated, or silver-plated gives an elegant appearance,
Magnetic induction on the working part of the magnet turns out to be very high,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
Due to the possibility of accurate forming and customization to individualized requirements, magnetic components can be manufactured in a wide range of shapes and sizes, which increases their versatility,
Universal use in advanced technology sectors – they are commonly used in data components, drive modules, medical devices, also modern systems.
Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Cons

Disadvantages of neodymium magnets:

To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
We recommend a housing - magnetic holder, due to difficulties in producing nuts inside the magnet and complicated forms.
Health risk resulting from small fragments of magnets can be dangerous, if swallowed, which is particularly important in the context of child safety. Additionally, small components of these devices are able to be problematic in diagnostics medical after entering the body.
With large orders the cost of neodymium magnets can be a barrier,

Pull force analysis

Maximum holding power of the magnet – what affects it?

The force parameter is a result of laboratory testing performed under standard conditions:

using a base made of low-carbon steel, acting as a ideal flux conductor
possessing a thickness of minimum 10 mm to avoid saturation
with a plane free of scratches
under conditions of gap-free contact (metal-to-metal)
for force acting at a right angle (pull-off, not shear)
at conditions approx. 20°C

Impact of factors on magnetic holding capacity in practice

Effective lifting capacity is influenced by specific conditions, such as (from priority):

Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
Direction of force – highest force is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is usually many times lower (approx. 1/5 of the lifting capacity).
Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Material composition – different alloys attracts identically. Alloy additives weaken the attraction effect.
Smoothness – full contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity was measured using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.

Precautions when working with NdFeB magnets

Life threat

People with a pacemaker should maintain an large gap from magnets. The magnetic field can stop the operation of the life-saving device.

Safe distance

Avoid bringing magnets close to a wallet, laptop, or screen. The magnetic field can permanently damage these devices and erase data from cards.

Beware of splinters

Beware of splinters. Magnets can explode upon violent connection, ejecting sharp fragments into the air. Wear goggles.

Do not overheat magnets

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

Crushing risk

Protect your hands. Two powerful magnets will join instantly with a force of massive weight, crushing anything in their path. Exercise extreme caution!

Avoid contact if allergic

A percentage of the population have a contact allergy to Ni, which is the typical protective layer for NdFeB magnets. Prolonged contact may cause skin redness. We strongly advise wear protective gloves.

Keep away from children

Always keep magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are life-threatening.

Phone sensors

An intense magnetic field negatively affects the functioning of magnetometers in phones and navigation systems. Maintain magnets near a device to avoid breaking the sensors.

Flammability

Powder generated during machining of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.

Immense force

Use magnets consciously. Their huge power can shock even experienced users. Stay alert and respect their power.
