It is an essential at every scrap yard, waste sorting plant, and workshop. Thanks to it, you can easily and quickly assess the value of scrap and avoid mistakes. It is also useful for pulling small steel elements from crates, ash, sand, or sawdust.

The tool reacts to carbon steel but does not attract most stainless steels (austenitic, like AISI 304). If the magnet does not attract the tested element, it is probably non-ferrous metal or acid-resistant steel.

Neodymium separators are much lighter and many times stronger than traditional ferrite ones. A lighter tool allows for longer work without wrist and arm pain. This is a modern solution displacing heavy and weak ferrite magnets.

The neodymium magnet is enclosed in a solid, metal housing (steel or brass). Tool ergonomics are key with frequent use by employees. 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). If you are looking for automatic dropping, ask about models with a magnetic release system. The sliding technique is more effective and requires less force than perpendicular tearing.

Strengths as well as weaknesses of Nd₂Fe₁₄B magnets.

Benefits

Besides their tremendous magnetic power, neodymium magnets offer the following advantages:

They virtually do not lose power, because even after ten years the performance loss is only ~1% (based on calculations),
Neodymium magnets are characterized by exceptionally resistant to magnetic field loss caused by external interference,
The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
Magnets possess impressive magnetic induction on the surface,
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 flexibility in constructing and the capacity to customize to client solutions,
Fundamental importance in modern technologies – they are used in HDD drives, electric motors, advanced medical instruments, also modern systems.
Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in compact constructions

Limitations

Drawbacks and weaknesses of neodymium magnets: application 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
We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Due to limitations in creating threads and complex forms in magnets, we propose using cover - magnetic mechanism.
Health risk resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these devices can be problematic in diagnostics medical after entering the body.
Due to expensive raw materials, their price is relatively high,

Pull force analysis

Detachment force of the magnet in optimal conditions – what contributes to it?

The load parameter shown represents the limit force, obtained under optimal environment, meaning:

with the use of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
possessing a massiveness of at least 10 mm to avoid saturation
with a plane free of scratches
with zero gap (without coatings)
during pulling in a direction vertical to the plane
at temperature approx. 20 degrees Celsius

Key elements affecting lifting force

It is worth knowing that the application force may be lower influenced by the following factors, in order of importance:

Space between magnet and steel – every millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
Direction of force – maximum parameter is reached only during pulling at a 90° angle. The shear force of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
Steel type – mild steel attracts best. Alloy admixtures lower magnetic permeability and holding force.
Surface condition – smooth surfaces ensure maximum contact, which increases force. Rough surfaces reduce efficiency.
Temperature influence – hot environment weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity was determined with the use of a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Moreover, even a small distance between the magnet’s surface and the plate lowers the load capacity.

Warnings

Precision electronics

Navigation devices and mobile phones are highly susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the internal compass in your phone.

Health Danger

Warning for patients: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or request help to handle the magnets.

Operating temperature

Monitor thermal conditions. Heating the magnet to high heat will ruin its properties and pulling force.

Mechanical processing

Machining of neodymium magnets carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.

Safe operation

Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.

Sensitization to coating

Certain individuals suffer from a contact allergy to Ni, which is the standard coating for neodymium magnets. Frequent touching may cause a rash. We recommend use safety gloves.

Beware of splinters

Watch out for shards. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.

This is not a toy

These products are not suitable for play. Swallowing multiple magnets can lead to them attracting across intestines, which poses a critical condition and requires urgent medical intervention.

Magnetic media

Very strong magnetic fields can erase data on credit cards, hard drives, and storage devices. Keep a distance of at least 10 cm.

Bone fractures

Danger of trauma: The pulling power is so great that it can result in hematomas, pinching, and broken bones. Protective gloves are recommended.
