This gripper serves for instant distinction of steel (iron) from non-ferrous metals. 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.

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. A solid handle (wooden, rubber, or plastic) ensures a firm and comfortable grip. 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). We also offer versions where pulling the handle automatically drops collected material. In the case of strong magnets, it is easiest to slide the metal to the side of the housing instead of tearing it straight off.

Advantages as well as disadvantages of rare earth magnets.

Pros

Besides their durability, neodymium magnets are valued for these benefits:

They have unchanged lifting capacity, and over around ten years their attraction force decreases symbolically – ~1% (according to theory),
They are extremely resistant to demagnetization induced by external disturbances,
Thanks to the reflective finish, the coating of Ni-Cu-Ni, gold-plated, or silver-plated gives an professional appearance,
The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
In view of the potential of free forming and customization to specialized needs, magnetic components can be produced in a variety of forms and dimensions, which makes them more universal,
Key role in future technologies – they are utilized in computer drives, brushless drives, advanced medical instruments, and complex engineering applications.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Limitations

What to avoid - cons of neodymium magnets and proposals for their use:

They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting 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 lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in realizing nuts and complex shapes in magnets, we recommend using a housing - magnetic holder.
Health risk resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. Additionally, tiny parts of these devices are able to disrupt the diagnostic process medical when they are in the body.
Due to expensive raw materials, their price is higher than average,

Pull force analysis

Maximum lifting force for a neodymium magnet – what affects it?

The force parameter is a measurement result performed under specific, ideal conditions:

with the application of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
with a cross-section of at least 10 mm
characterized by even structure
under conditions of no distance (metal-to-metal)
during detachment in a direction perpendicular to the mounting surface
in stable room temperature

Determinants of lifting force in real conditions

In practice, the real power results from several key aspects, listed from most significant:

Space between surfaces – every millimeter of separation (caused e.g. by veneer or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
Angle of force application – maximum parameter is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is standardly many 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.
Material composition – not every steel attracts identically. High carbon content weaken the attraction effect.
Base smoothness – the more even the plate, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
Operating temperature – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).

Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under perpendicular forces, however under parallel forces the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.

Safe handling of neodymium magnets

Physical harm

Big blocks can break fingers instantly. Under no circumstances put your hand between two strong magnets.

No play value

Neodymium magnets are not intended for children. Swallowing several magnets can lead to them connecting inside the digestive tract, which poses a direct threat to life and necessitates urgent medical intervention.

Eye protection

Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.

Magnetic media

Do not bring magnets near a wallet, laptop, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.

Thermal limits

Do not overheat. Neodymium magnets are susceptible to temperature. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).

Medical implants

Warning for patients: Powerful magnets disrupt electronics. Maintain minimum 30 cm distance or request help to handle the magnets.

Handling rules

Before use, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.

Precision electronics

An intense magnetic field negatively affects the operation of compasses in phones and navigation systems. Do not bring magnets near a device to avoid damaging the sensors.

Allergy Warning

Nickel alert: The nickel-copper-nickel coating consists of nickel. If an allergic reaction happens, cease handling magnets and use protective gear.

Flammability

Powder generated during grinding of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.

Caution! More info about risks in the article: Safety of working with magnets.
