It is the "heart" of every magnetic filter used in industry for cleaning raw materials. 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 rod consists of a cover tube made of high-quality acid-resistant steel (AISI 304 or 316). 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. 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. High Power versions (~12000-14000 Gs) are necessary for catching metallic dust, oxides, and stainless steel after processing.
We fulfill individual orders for bars perfectly matched to your machine or separator. The rod end is strictly adapted to the fastening system in your device. We ensure fast realization of special orders and technical advice.

Pros as well as cons of neodymium magnets.

Pros

Besides their remarkable strength, neodymium magnets offer the following advantages:
  • They do not lose magnetism, even over nearly 10 years – the drop in strength is only ~1% (theoretically),
  • Neodymium magnets are characterized by highly resistant to magnetic field loss caused by external interference,
  • By covering with a reflective layer of nickel, the element acquires an elegant look,
  • The surface of neodymium magnets generates a maximum magnetic field – this is a key feature,
  • Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • Thanks to modularity in shaping and the capacity to adapt to client solutions,
  • Wide application in modern technologies – they find application in mass storage devices, drive modules, precision medical tools, as well as technologically advanced constructions.
  • Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in compact constructions

Cons

Disadvantages of neodymium magnets:
  • They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only shields the magnet but also increases its resistance to damage
  • When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their power 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 oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • Due to limitations in realizing nuts and complex forms in magnets, we recommend using a housing - magnetic holder.
  • Health risk resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the context of child safety. Additionally, small components of these magnets can be problematic in diagnostics medical after entering the body.
  • With mass production the cost of neodymium magnets is economically unviable,

Pull force analysis

Maximum lifting capacity of the magnetwhat it depends on?

The declared magnet strength represents the peak performance, recorded under optimal environment, meaning:
  • on a plate made of mild steel, effectively closing the magnetic flux
  • possessing a thickness of at least 10 mm to avoid saturation
  • with an ground contact surface
  • without the slightest clearance between the magnet and steel
  • during detachment in a direction perpendicular to the mounting surface
  • at ambient temperature room level

Impact of factors on magnetic holding capacity in practice

Effective lifting capacity impacted by specific conditions, such as (from priority):
  • Gap (between the magnet and the plate), since even a microscopic distance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to paint, corrosion or dirt).
  • Load vector – highest force is reached only during pulling at a 90° angle. The force required to slide of the magnet along the plate is standardly several times smaller (approx. 1/5 of the lifting capacity).
  • Base massiveness – insufficiently thick steel does not accept the full field, causing part of the power to be escaped to the other side.
  • Steel grade – the best choice is high-permeability steel. Hardened steels may have worse magnetic properties.
  • Plate texture – smooth surfaces ensure maximum contact, which improves force. Rough surfaces weaken the grip.
  • Thermal factor – high temperature reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity was assessed by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate reduces the load capacity.

Safety rules for work with NdFeB magnets
Sensitization to coating

Some people experience a sensitization to Ni, which is the common plating for neodymium magnets. Frequent touching may cause dermatitis. We suggest wear safety gloves.

Permanent damage

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

ICD Warning

Individuals with a heart stimulator have to keep an large gap from magnets. The magnetism can interfere with the operation of the implant.

This is not a toy

Adult use only. Tiny parts pose a choking risk, leading to intestinal necrosis. Keep away from children and animals.

Magnets are brittle

Despite the nickel coating, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.

Pinching danger

Mind your fingers. Two large magnets will snap together instantly with a force of massive weight, crushing everything in their path. Be careful!

Handling rules

Use magnets with awareness. Their immense force can surprise even experienced users. Be vigilant and respect their power.

Threat to electronics

Very strong magnetic fields can erase data on payment cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.

Fire warning

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

Precision electronics

GPS units and smartphones are extremely susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can decalibrate the sensors in your phone.
