Magnetic Field

Other proposals

A magnetic rod is the basic element of building grate separators and magnetic filters. It is commonly used for cleaning flour, sugar, plastic granules, as well as oils and coolants. High magnetic induction on the surface allows catching the finest iron particles.
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. You can use compressed air or special non-magnetic strippers (rings). For easier operation, it is worth considering ordering a rod in a version with a cleaning sleeve.
The Gauss value tells us how effectively and deeply the magnet will catch contaminants. The economical version (8kGs) handles large pieces of metal perfectly. High induction is necessary when contaminants are microscopic or weakly magnetic.
We can produce a rod of non-standard length with any mounting termination. You can choose a mounting method consistent with your technical design. Contact us for a quote on a non-standard dimension.

Pros and cons of neodymium magnets.

Advantages

Besides their magnetic performance, neodymium magnets are valued for these benefits:
  • They do not lose power, even after approximately ten years – the drop in lifting capacity is only ~1% (based on measurements),
  • They feature excellent resistance to magnetism drop due to external fields,
  • In other words, due to the reflective finish of nickel, the element gains visual value,
  • Magnetic induction on the surface of the magnet turns out to be extremely intense,
  • Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures approaching 230°C and above...
  • Possibility of accurate modeling and adjusting to concrete requirements,
  • Huge importance in advanced technology sectors – they serve a role in magnetic memories, motor assemblies, diagnostic systems, as well as technologically advanced constructions.
  • Compactness – despite small sizes they generate large force, making them ideal for precision applications

Limitations

Disadvantages of NdFeB magnets:
  • Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only secures them against impacts but also increases their durability
  • We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
  • They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
  • Due to limitations in producing threads and complicated forms in magnets, we recommend using cover - magnetic holder.
  • Health risk to health – tiny shards 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 small components of these products can be problematic in diagnostics medical in case of swallowing.
  • Due to expensive raw materials, their price is higher than average,

Lifting parameters

Maximum lifting force for a neodymium magnet – what it depends on?

Holding force of 0.00 kg is a result of laboratory testing conducted under standard conditions:
  • on a block made of mild steel, perfectly concentrating the magnetic field
  • possessing a thickness of minimum 10 mm to avoid saturation
  • characterized by even structure
  • under conditions of ideal adhesion (surface-to-surface)
  • during detachment in a direction vertical to the mounting surface
  • at standard ambient temperature

Magnet lifting force in use – key factors

Bear in mind that the working load will differ depending on the following factors, in order of importance:
  • Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
  • Angle of force application – maximum parameter is reached only during perpendicular pulling. The shear force of the magnet along the plate is typically many times lower (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 generating force.
  • Material type – the best choice is pure iron steel. Cast iron may generate lower lifting capacity.
  • Surface condition – smooth surfaces ensure maximum contact, which increases field saturation. Uneven metal reduce efficiency.
  • Thermal factor – high temperature reduces pulling force. Too high temperature can permanently demagnetize the magnet.

Lifting capacity testing was performed on a smooth plate of suitable thickness, under perpendicular forces, whereas under attempts to slide the magnet the load capacity is reduced by as much as 75%. Moreover, even a minimal clearance between the magnet and the plate lowers the lifting capacity.

Safety rules for work with NdFeB magnets
Threat to navigation

A powerful magnetic field interferes with the operation of magnetometers in smartphones and navigation systems. Do not bring magnets close to a smartphone to prevent breaking the sensors.

Avoid contact if allergic

It is widely known that nickel (standard magnet coating) is a strong allergen. If your skin reacts to metals, avoid direct skin contact and select encased magnets.

Product not for children

Neodymium magnets are not toys. Accidental ingestion of a few magnets may result in them pinching intestinal walls, which constitutes a critical condition and necessitates urgent medical intervention.

Crushing force

Risk of injury: The attraction force is so immense that it can result in blood blisters, crushing, and broken bones. Protective gloves are recommended.

Caution required

Before use, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.

Keep away from computers

Powerful magnetic fields can destroy records on payment cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.

Power loss in heat

Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will destroy its magnetic structure and strength.

Flammability

Powder created during grinding of magnets is self-igniting. Do not drill into magnets unless you are an expert.

Material brittleness

Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.

Life threat

People with a ICD have to keep an safe separation from magnets. The magnetic field can stop the operation of the life-saving device.
