Frequently asked questions

Which rod should I choose for fine contamination?
For particles below 0.5 mm — a Ø32 mm rod in grade N52, with surface induction of about 10,000 Gs. A Ø25 rod in grade N42 gives about 6,500 Gs and is chosen for contamination above 1 mm: bolts, washers, pieces of wire.
Which rod pitch should I choose?
The narrow pitch, 40 mm centre to centre, for fine free-flowing fractions — it gives denser coverage of the cross-section. The wide pitch, 50 mm, for granulates and for damp, greasy or sticky materials, where a narrow pitch risks the material bridging above the rods.
Why does efficiency drop after a few weeks of operation?
Almost always because the separator has not been cleaned. The layer of captured particles shields the field, and further particles settle on that layer rather than on the rod surface, where the gradient is far stronger. The magnets themselves do not weaken at that rate.

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. High magnetic induction on the surface allows catching the finest iron particles.
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. 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.
Yes, as a manufacturer, we make rods of any length and diameter (standard is dia 25mm and 32mm). 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.

Advantages and disadvantages of neodymium magnets.

Strengths

In addition to their magnetic capacity, neodymium magnets provide the following advantages:
  • They have unchanged lifting capacity, and over nearly ten years their performance decreases symbolically – ~1% (in testing),
  • Neodymium magnets are distinguished by extremely resistant to demagnetization caused by magnetic disturbances,
  • The use of an metallic coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
  • Neodymium magnets achieve maximum magnetic induction on a small surface, which ensures high operational effectiveness,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
  • Possibility of individual forming as well as adjusting to specific requirements,
  • Key role in modern industrial fields – they are used in computer drives, drive modules, medical equipment, as well as other advanced devices.
  • Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which enables their usage in miniature devices

Weaknesses

What to avoid - cons of neodymium magnets and proposals for their use:
  • At very strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • Due to limitations in creating nuts and complex forms in magnets, we recommend using a housing - magnetic mechanism.
  • Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that tiny parts of these products are able to be problematic in diagnostics medical after entering the body.
  • With budget limitations the cost of neodymium magnets is economically unviable,

Pull force analysis

Maximum lifting capacity of the magnet – what affects it?

Breakaway force was determined for ideal contact conditions, assuming:
  • using a base made of low-carbon steel, functioning as a ideal flux conductor
  • possessing a massiveness of minimum 10 mm to ensure full flux closure
  • with an ideally smooth contact surface
  • without the slightest clearance between the magnet and steel
  • for force applied at a right angle (pull-off, not shear)
  • at ambient temperature approx. 20 degrees Celsius

Key elements affecting lifting force

It is worth knowing that the magnet holding may be lower influenced by the following factors, starting with the most relevant:
  • Clearance – existence of any layer (rust, dirt, air) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
  • Angle of force application – maximum parameter is reached only during perpendicular pulling. The resistance to sliding of the magnet along the plate is standardly several times smaller (approx. 1/5 of the lifting capacity).
  • Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
  • Material composition – not every steel attracts identically. Alloy additives worsen the attraction effect.
  • Surface structure – the more even the plate, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
  • Thermal environment – heating the magnet causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.

Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, whereas under parallel forces the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate reduces the holding force.

Warnings
Phone sensors

A powerful magnetic field interferes with the operation of magnetometers in phones and GPS navigation. Keep magnets close to a device to avoid breaking the sensors.

Risk of cracking

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

Product not for children

These products are not toys. Accidental ingestion of several magnets can lead to them pinching intestinal walls, which constitutes a direct threat to life and necessitates immediate surgery.

Caution required

Handle with care. Rare earth magnets attract from a long distance and connect with huge force, often quicker than you can move away.

Magnetic media

Equipment safety: Strong magnets can damage payment cards and delicate electronics (pacemakers, medical aids, timepieces).

Allergy Warning

Studies show that the nickel plating (the usual finish) is a potent allergen. If you have an allergy, avoid touching magnets with bare hands and opt for encased magnets.

Danger to pacemakers

Medical warning: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.

Thermal limits

Avoid heat. NdFeB magnets are susceptible to temperature. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).

Do not drill into magnets

Powder produced during cutting of magnets is combustible. Avoid drilling into magnets unless you are an expert.

Pinching danger

Protect your hands. Two powerful magnets will snap together instantly with a force of massive weight, crushing anything in their path. Be careful!
