A manual separator is a basic tool for quick identification and sorting of metals. Thanks to it, you can easily and quickly assess the value of scrap and avoid mistakes. It can be used to collect scattered nails and screws from hard-to-reach places.
A neodymium magnet attracts only ferromagnetic metals, such as ordinary steel (black) and cast iron. Lack of reaction (attraction) means the tested item is made of non-magnetic material.
The neodymium model offers powerful force with low weight, which drastically reduces hand fatigue. Strong neodymium field detects even weakly magnetic alloys and contaminants. This is a modern solution displacing heavy and weak ferrite magnets.
The magnet is completely shielded from mechanical impacts, which extends its lifespan. A solid handle (wooden, rubber, or plastic) ensures a firm and comfortable grip. Thanks to such an armored build, the separator is resistant to difficult conditions prevailing at a scrap yard.
In this model, collected metal must be torn off manually (preferably in a work glove). Models with a release lever (so-called grippers with a dropper) are also available in another category. The sliding technique is more effective and requires less force than perpendicular tearing.

Advantages and disadvantages of neodymium magnets.

Pros

Besides their exceptional field intensity, neodymium magnets offer the following advantages:
  • They retain full power for around ten years – the loss is just ~1% (in theory),
  • They are resistant to demagnetization induced by external field influence,
  • Thanks to the glossy finish, the coating of nickel, gold-plated, or silver gives an aesthetic appearance,
  • The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
  • Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
  • Thanks to modularity in shaping and the ability to customize to specific needs,
  • Versatile presence in high-tech industry – they serve a role in hard drives, electromotive mechanisms, medical devices, also industrial machines.
  • Thanks to their power density, small magnets offer high operating force, occupying minimum space,

Disadvantages

What to avoid - cons of neodymium magnets: application proposals
  • To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
  • We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
  • When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
  • We suggest casing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complex shapes.
  • Possible danger resulting from small fragments 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 magnets are able to complicate diagnosis medical in case of swallowing.
  • With mass production the cost of neodymium magnets can be a barrier,

Pull force analysis

Maximum holding power of the magnet – what contributes to it?

Magnet power was defined for optimal configuration, including:
  • on a block made of structural steel, optimally conducting the magnetic flux
  • with a cross-section minimum 10 mm
  • characterized by smoothness
  • without any air gap between the magnet and steel
  • for force applied at a right angle (in the magnet axis)
  • in neutral thermal conditions

Magnet lifting force in use – key factors

It is worth knowing that the magnet holding will differ depending on elements below, starting with the most relevant:
  • Distance – the presence of any layer (rust, dirt, air) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
  • Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
  • Plate thickness – too thin steel does not accept the full field, causing part of the power to be lost into the air.
  • Material composition – not every steel reacts the same. Alloy additives worsen the attraction effect.
  • Base smoothness – the smoother and more polished the surface, the better the adhesion and stronger the hold. Roughness creates an air distance.
  • Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet and the plate reduces the holding force.

H&S for magnets
Physical harm

Risk of injury: The pulling power is so great that it can result in blood blisters, crushing, and broken bones. Use thick gloves.

Respect the power

Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.

Danger to pacemakers

People with a ICD have to maintain an absolute distance from magnets. The magnetism can interfere with the operation of the implant.

Power loss in heat

Regular neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. This process is irreversible.

Warning for allergy sufferers

Studies show that nickel (the usual finish) is a potent allergen. If you have an allergy, refrain from direct skin contact and choose versions in plastic housing.

Data carriers

Powerful magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Maintain a gap of at least 10 cm.

Magnet fragility

Beware of splinters. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.

Dust is flammable

Dust created during grinding of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.

Compass and GPS

Remember: rare earth magnets produce a field that disrupts precision electronics. Maintain a separation from your mobile, device, and GPS.

Do not give to children

Adult use only. Tiny parts pose a choking risk, causing intestinal necrosis. Store away from children and animals.
