This gripper serves for instant distinction of steel (iron) from non-ferrous 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.
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.
The neodymium model offers powerful force with low weight, which drastically reduces hand fatigue. Thanks to this, work is more comfortable, and detection faster and more certain. This is a modern solution displacing heavy and weak ferrite magnets.
The construction consists of a hermetic can protecting the magnet and an ergonomic handle. 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). If you are looking for automatic dropping, ask about models with a magnetic release system. 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.

Pros and cons of neodymium magnets.

Pros

Besides their high retention, neodymium magnets are valued for these benefits:
  • They do not lose power, even after around 10 years – the decrease in lifting capacity is only ~1% (according to tests),
  • They have excellent resistance to magnetism drop due to external fields,
  • In other words, due to the smooth surface of nickel, the element is aesthetically pleasing,
  • The surface of neodymium magnets generates a maximum magnetic field – this is a key feature,
  • Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
  • Thanks to the ability of free forming and adaptation to custom needs, magnetic components can be produced in a broad palette of shapes and sizes, which amplifies use scope,
  • Key role in high-tech industry – they find application in computer drives, drive modules, diagnostic systems, and other advanced devices.
  • Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which allows their use in compact constructions

Disadvantages

Problematic aspects of neodymium magnets and ways of using them
  • At very strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
  • They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • Limited ability of making nuts in the magnet and complex shapes - recommended is cover - magnet mounting.
  • Possible danger related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that tiny parts of these products can disrupt the diagnostic process medical in case of swallowing.
  • With budget limitations the cost of neodymium magnets is a challenge,

Lifting parameters

Detachment force of the magnet in optimal conditionswhat affects it?

Magnet power was defined for ideal contact conditions, including:
  • on a plate made of mild steel, effectively closing the magnetic field
  • with a thickness minimum 10 mm
  • with a surface cleaned and smooth
  • with direct contact (no coatings)
  • during pulling in a direction vertical to the mounting surface
  • at conditions approx. 20°C

Practical lifting capacity: influencing factors

It is worth knowing that the application force may be lower depending on elements below, in order of importance:
  • Clearance – the presence of any layer (rust, dirt, gap) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
  • Loading method – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
  • Base massiveness – too thin sheet does not accept the full field, causing part of the flux to be lost to the other side.
  • Steel type – mild steel attracts best. Alloy admixtures lower magnetic permeability and lifting capacity.
  • Plate texture – smooth surfaces ensure maximum contact, which improves force. Uneven metal reduce efficiency.
  • Temperature influence – high temperature reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under parallel forces the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate lowers the holding force.

Safety rules for work with neodymium magnets
Threat to navigation

Remember: neodymium magnets generate a field that confuses sensitive sensors. Keep a safe distance from your mobile, device, and navigation systems.

Dust explosion hazard

Dust produced during grinding of magnets is flammable. Do not drill into magnets unless you are an expert.

No play value

Product intended for adults. Tiny parts can be swallowed, causing intestinal necrosis. Keep away from kids and pets.

Demagnetization risk

Regular neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. The loss of strength is permanent.

Hand protection

Mind your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, crushing anything in their path. Be careful!

Safe distance

Powerful magnetic fields can destroy records on credit cards, hard drives, and storage devices. Stay away of at least 10 cm.

ICD Warning

Health Alert: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.

Beware of splinters

Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.

Warning for allergy sufferers

Certain individuals experience a sensitization to Ni, which is the standard coating for neodymium magnets. Frequent touching may cause dermatitis. We suggest wear protective gloves.

Respect the power

Handle magnets consciously. Their huge power can surprise even experienced users. Be vigilant and respect their power.
