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 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. Such construction ensures full resistance to corrosion, water, oils, and acids.
Due to the high power of the magnet, direct removal of filings can be troublesome and time-consuming. 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 more Gauss, the smaller and more weakly magnetic particles will be effectively caught. Standard rods (~8000 Gs) are sufficient for catching screws, nails, and steel shavings. High Power versions (~12000-14000 Gs) are necessary for catching metallic dust, oxides, and stainless steel after processing.
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.

Pros and cons of neodymium magnets.

Strengths

Besides their stability, neodymium magnets are valued for these benefits:
  • They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
  • They are resistant to demagnetization induced by external disturbances,
  • In other words, due to the aesthetic finish of nickel, the element is aesthetically pleasing,
  • The surface of neodymium magnets generates a strong magnetic field – this is one of their assets,
  • Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures approaching 230°C and above...
  • Possibility of exact machining as well as optimizing to precise conditions,
  • Key role in electronics industry – they find application in data components, drive modules, advanced medical instruments, and technologically advanced constructions.
  • Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Cons

Problematic aspects of neodymium magnets: weaknesses and usage proposals
  • They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
  • Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
  • They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
  • Due to limitations in creating threads and complicated shapes in magnets, we recommend using casing - magnetic mount.
  • Health risk related to microscopic parts of magnets can be dangerous, in case of ingestion, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these devices are able to be problematic in diagnostics medical when they are in the body.
  • With mass production the cost of neodymium magnets is a challenge,

Pull force analysis

Maximum magnetic pulling forcewhat affects it?

The load parameter shown represents the maximum value, recorded under laboratory conditions, specifically:
  • on a plate made of mild steel, optimally conducting the magnetic flux
  • with a thickness no less than 10 mm
  • with a surface free of scratches
  • without any insulating layer between the magnet and steel
  • during detachment in a direction vertical to the mounting surface
  • at ambient temperature room level

Determinants of lifting force in real conditions

Effective lifting capacity is influenced by specific conditions, such as (from most important):
  • Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
  • Load vector – maximum parameter is reached only during perpendicular pulling. The shear force of the magnet along the plate is standardly several times smaller (approx. 1/5 of the lifting capacity).
  • Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
  • Material type – ideal substrate is high-permeability steel. Cast iron may attract less.
  • Surface condition – ground elements ensure maximum contact, which increases field saturation. Rough surfaces reduce efficiency.
  • Temperature influence – hot environment weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.

Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the load capacity is reduced by as much as fivefold. In addition, even a minimal clearance between the magnet and the plate decreases the holding force.

Precautions when working with neodymium magnets
Safe distance

Intense magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Stay away of at least 10 cm.

Magnetic interference

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

Medical implants

For implant holders: Strong magnetic fields affect electronics. Keep at least 30 cm distance or ask another person to work with the magnets.

Respect the power

Before starting, check safety instructions. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.

Combustion hazard

Fire warning: Neodymium dust is highly flammable. Do not process magnets without safety gear as this risks ignition.

Permanent damage

Monitor thermal conditions. Heating the magnet to high heat will permanently weaken its magnetic structure and strength.

Avoid contact if allergic

Some people suffer from a hypersensitivity to Ni, which is the common plating for NdFeB magnets. Extended handling might lead to skin redness. We recommend wear protective gloves.

Bone fractures

Risk of injury: The pulling power is so immense that it can cause hematomas, pinching, and even bone fractures. Use thick gloves.

Danger to the youngest

Product intended for adults. Tiny parts pose a choking risk, causing intestinal necrosis. Keep away from kids and pets.

Protective goggles

Protect your eyes. Magnets can explode upon violent connection, launching shards into the air. We recommend safety glasses.
