Shopping tips

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. 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 contaminants are strongly attracted, so removing them with a bare hand or glove can be difficult. 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 Gauss value tells us how effectively and deeply the magnet will catch contaminants. Standard rods (~8000 Gs) are sufficient for catching screws, nails, and steel shavings. 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.

Pros as well as cons of neodymium magnets.

In addition to their long-term stability, neodymium magnets provide the following advantages:

  • They do not lose magnetism, even after nearly ten years – the drop in power is only ~1% (based on measurements),
  • They are resistant to demagnetization induced by external field influence,
  • A magnet with a metallic gold surface looks better,
  • Magnetic induction on the working part of the magnet is extremely intense,
  • Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures approaching 230°C and above...
  • Thanks to versatility in designing and the ability to adapt to specific needs,
  • Key role in high-tech industry – they find application in computer drives, drive modules, medical equipment, and modern systems.
  • Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,

Characteristics of disadvantages of neodymium magnets: application proposals

  • Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a steel housing, which not only protects them against impacts but also increases their durability
  • NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
  • When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
  • Limited ability of producing nuts in the magnet and complicated forms - recommended is cover - magnetic holder.
  • Potential hazard related to microscopic parts of magnets can be dangerous, if swallowed, which gains importance in the context of child safety. Additionally, tiny parts of these magnets can disrupt the diagnostic process medical after entering the body.
  • Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Best holding force of the magnet in ideal parameterswhat contributes to it?

The specified lifting capacity concerns the limit force, recorded under ideal test conditions, meaning:

  • on a plate made of structural steel, perfectly concentrating the magnetic field
  • with a thickness of at least 10 mm
  • with a surface free of scratches
  • without the slightest insulating layer between the magnet and steel
  • under axial application of breakaway force (90-degree angle)
  • at temperature approx. 20 degrees Celsius

Lifting capacity in real conditions – factors

In practice, the real power is determined by many variables, presented from most significant:

  • Gap (between the magnet and the plate), since even a tiny clearance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
  • Load vector – highest force is available only during perpendicular pulling. The force required to slide of the magnet along the plate is typically many times smaller (approx. 1/5 of the lifting capacity).
  • Plate thickness – too thin sheet causes magnetic saturation, causing part of the flux to be wasted into the air.
  • Material type – ideal substrate is high-permeability steel. Hardened steels may generate lower lifting capacity.
  • Surface structure – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
  • Thermal conditions – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).

* Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, in contrast under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a slight gap {between} the magnet’s surface and the plate lowers the holding force.

Warnings

Handling guide

Use magnets with awareness. Their immense force can surprise even experienced users. Plan your moves and respect their power.

Product not for children

Absolutely store magnets out of reach of children. Ingestion danger is high, and the effects of magnets clamping inside the body are very dangerous.

Fire warning

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

Danger to pacemakers

Health Alert: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.

Demagnetization risk

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

Magnets are brittle

Despite metallic appearance, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.

Metal Allergy

Certain individuals have a contact allergy to nickel, which is the typical protective layer for NdFeB magnets. Frequent touching can result in an allergic reaction. We suggest wear safety gloves.

Pinching danger

Big blocks can crush fingers in a fraction of a second. Do not put your hand between two attracting surfaces.

Keep away from electronics

An intense magnetic field interferes with the functioning of compasses in phones and navigation systems. Maintain magnets near a smartphone to avoid breaking the sensors.

Magnetic media

Device Safety: Neodymium magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, timepieces).
