Magnetic Field

Other offers

It is an essential at every scrap yard, waste sorting plant, and workshop. 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 neodymium magnet is enclosed in a solid, metal housing (steel or brass). The grip was designed so as not to slip in the hand, even in a work glove. The tool is durable, drop-resistant, and prepared for hard work.
It is a simple and reliable construction without moving parts, so cleaning consists of removing scrap. 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 and disadvantages of Nd2Fe14B magnets.

Strengths

Besides their remarkable field intensity, neodymium magnets offer the following advantages:
  • They have unchanged lifting capacity, and over around 10 years their performance decreases symbolically – ~1% (in testing),
  • Magnets perfectly protect themselves against loss of magnetization caused by ambient magnetic noise,
  • Thanks to the reflective finish, the coating of Ni-Cu-Ni, gold, or silver gives an modern appearance,
  • They show high magnetic induction at the operating surface, which increases their power,
  • Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • Possibility of precise modeling and adjusting to specific conditions,
  • Versatile presence in electronics industry – they are commonly used in data components, motor assemblies, medical devices, and modern systems.
  • Thanks to their power density, small magnets offer high operating force, occupying minimum space,

Weaknesses

Problematic aspects of neodymium magnets and ways of using them
  • To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
  • We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
  • They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • We recommend casing - magnetic holder, due to difficulties in creating nuts inside the magnet and complicated forms.
  • Possible danger to health – tiny shards of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. Furthermore, tiny parts of these products can be problematic in diagnostics medical in case of swallowing.
  • High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities

Holding force characteristics

Detachment force of the magnet in optimal conditionswhat affects it?

The specified lifting capacity concerns the maximum value, obtained under laboratory conditions, meaning:
  • using a plate made of low-carbon steel, functioning as a ideal flux conductor
  • whose transverse dimension equals approx. 10 mm
  • characterized by even structure
  • without any clearance between the magnet and steel
  • under vertical force direction (90-degree angle)
  • in temp. approx. 20°C

Lifting capacity in real conditions – factors

In real-world applications, the real power is determined by a number of factors, presented from crucial:
  • Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
  • Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
  • Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
  • Metal type – not every steel attracts identically. High carbon content worsen the interaction with the magnet.
  • Plate texture – ground elements ensure maximum contact, which improves force. Rough surfaces reduce efficiency.
  • Temperature – heating the magnet causes a temporary drop of induction. Check the maximum operating temperature for a given model.

Lifting capacity was assessed by applying a smooth 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 minimal clearance between the magnet and the plate reduces the lifting capacity.

Safe handling of neodymium magnets
Bone fractures

Large magnets can crush fingers instantly. Do not place your hand betwixt two attracting surfaces.

Allergy Warning

Nickel alert: The nickel-copper-nickel coating contains nickel. If an allergic reaction happens, cease handling magnets and wear gloves.

Magnetic media

Data protection: Neodymium magnets can ruin payment cards and delicate electronics (pacemakers, medical aids, timepieces).

Heat warning

Standard neodymium magnets (grade N) undergo demagnetization when the temperature goes above 80°C. The loss of strength is permanent.

Product not for children

These products are not intended for children. Accidental ingestion of multiple magnets can lead to them pinching intestinal walls, which poses a critical condition and requires urgent medical intervention.

Keep away from electronics

GPS units and smartphones are highly sensitive to magnetism. Close proximity with a powerful NdFeB magnet can permanently damage the sensors in your phone.

Material brittleness

NdFeB magnets are sintered ceramics, which means they are prone to chipping. Impact of two magnets will cause them breaking into small pieces.

Fire risk

Drilling and cutting of neodymium magnets poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.

Do not underestimate power

Use magnets with awareness. Their huge power can surprise even experienced users. Stay alert and respect their power.

Warning for heart patients

Patients with a ICD should maintain an large gap from magnets. The magnetic field can disrupt the functioning of the life-saving device.
