Frequently asked questions

Which rod should I choose for fine contamination?
For particles below 0.5 mm — a Ø32 mm rod in grade N52, with surface induction of about 10,000 Gs. A Ø25 rod in grade N42 gives about 6,500 Gs and is chosen for contamination above 1 mm: bolts, washers, pieces of wire.
Which rod pitch should I choose?
The narrow pitch, 40 mm centre to centre, for fine free-flowing fractions — it gives denser coverage of the cross-section. The wide pitch, 50 mm, for granulates and for damp, greasy or sticky materials, where a narrow pitch risks the material bridging above the rods.
Why does efficiency drop after a few weeks of operation?
Almost always because the separator has not been cleaned. The layer of captured particles shields the field, and further particles settle on that layer rather than on the rod surface, where the gradient is far stronger. The magnets themselves do not weaken at that rate.

A manual separator is a basic tool for quick identification and sorting of metals. It enables effective segregation of materials in the yard and accepting goods. 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.
Neodymiums are more compact and effective during all-day work at a scrap yard. Strong neodymium field detects even weakly magnetic alloys and contaminants. The neodymium version is currently the standard in professional scrap yards.
The magnet is completely shielded from mechanical impacts, which extends its lifespan. Tool ergonomics are key with frequent use by employees. The tool is durable, drop-resistant, and prepared for hard work.
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 rare earth magnets.

Advantages

Besides their immense strength, neodymium magnets offer the following advantages:
  • They virtually do not lose power, because even after ten years the performance loss is only ~1% (according to literature),
  • They maintain their magnetic properties even under external field action,
  • The use of an metallic layer of noble metals (nickel, gold, silver) causes the element to have aesthetics,
  • Magnets possess extremely high magnetic induction on the active area,
  • Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures approaching 230°C and above...
  • Thanks to freedom in forming and the ability to modify to unusual requirements,
  • Key role in innovative solutions – they are utilized in HDD drives, brushless drives, precision medical tools, as well as modern systems.
  • Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,

Weaknesses

Problematic aspects of neodymium magnets and ways of using them
  • At very strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
  • NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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
  • They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • Limited ability of producing nuts in the magnet and complicated forms - preferred is cover - magnet mounting.
  • Health risk related to microscopic parts of magnets pose a threat, in case of ingestion, which becomes key in the context of child health protection. Additionally, tiny parts of these devices can complicate diagnosis medical when they are in the body.
  • With mass production the cost of neodymium magnets can be a barrier,

Lifting parameters

Breakaway strength of the magnet in ideal conditions – what affects it?

Magnet power was defined for the most favorable conditions, including:
  • using a sheet made of mild steel, serving as a ideal flux conductor
  • with a cross-section minimum 10 mm
  • with a surface perfectly flat
  • with direct contact (no coatings)
  • during pulling in a direction vertical to the plane
  • at conditions approx. 20°C

Key elements affecting lifting force

It is worth knowing that the working load may be lower influenced by elements below, in order of importance:
  • Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
  • Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of nominal force).
  • Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
  • Chemical composition of the base – low-carbon steel attracts best. Higher carbon content decrease magnetic permeability and lifting capacity.
  • Plate texture – smooth surfaces guarantee perfect abutment, which increases force. Rough surfaces reduce efficiency.
  • Thermal factor – high temperature reduces magnetic field. Too high temperature can permanently damage the magnet.

Lifting capacity was assessed by applying a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast under parallel forces the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate lowers the holding force.

Precautions when working with NdFeB magnets
Dust explosion hazard

Fire warning: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this risks ignition.

Choking Hazard

Adult use only. Tiny parts can be swallowed, causing intestinal necrosis. Keep away from children and animals.

Life threat

Individuals with a heart stimulator have to keep an absolute distance from magnets. The magnetism can disrupt the functioning of the life-saving device.

GPS and phone interference

An intense magnetic field negatively affects the operation of magnetometers in phones and GPS navigation. Keep magnets near a smartphone to prevent damaging the sensors.

Warning for allergy sufferers

Nickel alert: The nickel-copper-nickel coating contains nickel. If skin irritation happens, immediately stop working with magnets and use protective gear.

Bone fractures

Mind your fingers. Two powerful magnets will snap together immediately with a force of massive weight, destroying everything in their path. Be careful!

Electronic hazard

Very strong magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Stay away of min. 10 cm.

Handling guide

Before use, read the rules. Sudden snapping can break the magnet or injure your hand. Think ahead.

Do not overheat magnets

Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and pulling force.

Magnets are brittle

Protect your eyes. Magnets can explode upon violent connection, launching shards into the air. Eye protection is mandatory.
