Field Strength

Other products

A manual separator is a basic tool for quick identification and sorting of 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.
A neodymium magnet attracts only ferromagnetic metals, such as ordinary steel (black) and cast iron. 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. 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 magnet is completely shielded from mechanical impacts, which extends its lifespan. 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.
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 neodymium magnets.

Pros

Apart from their consistent holding force, neodymium magnets have these key benefits:
  • Their magnetic field remains stable, and after approximately ten years it drops only by ~1% (according to research),
  • They retain their magnetic properties even under close interference source,
  • In other words, due to the shiny finish of nickel, the element gains visual value,
  • Magnetic induction on the working layer of the magnet turns out to be maximum,
  • 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...
  • Thanks to versatility in constructing and the capacity to adapt to specific needs,
  • Wide application in innovative solutions – they are commonly used in computer drives, motor assemblies, advanced medical instruments, also other advanced devices.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Disadvantages

What to avoid - cons of neodymium magnets: application proposals
  • To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
  • Neodymium 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 and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
  • Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
  • We recommend a housing - magnetic holder, due to difficulties in creating threads inside the magnet and complicated shapes.
  • Possible danger resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child health protection. It is also worth noting that small components of these devices are able to complicate diagnosis medical in case of swallowing.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Breakaway strength of the magnet in ideal conditionswhat it depends on?

The declared magnet strength concerns the maximum value, measured under optimal environment, namely:
  • using a base made of high-permeability steel, acting as a ideal flux conductor
  • whose thickness is min. 10 mm
  • characterized by even structure
  • with total lack of distance (no coatings)
  • during pulling in a direction vertical to the mounting surface
  • at standard ambient temperature

What influences lifting capacity in practice

In real-world applications, the actual lifting capacity depends on a number of factors, listed from most significant:
  • Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
  • Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
  • Plate thickness – too thin plate does not close the flux, causing part of the flux to be escaped into the air.
  • Material composition – not every steel reacts the same. High carbon content weaken the interaction with the magnet.
  • Surface finish – ideal contact is possible only on polished steel. Rough texture create air cushions, weakening the magnet.
  • Operating temperature – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).

Lifting capacity testing was carried out on a smooth plate of optimal thickness, under a perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. Moreover, even a slight gap between the magnet and the plate lowers the load capacity.

Safe handling of NdFeB magnets
Electronic hazard

Device Safety: Strong magnets can damage payment cards and sensitive devices (pacemakers, hearing aids, timepieces).

Life threat

Individuals with a heart stimulator should keep an safe separation from magnets. The magnetism can stop the functioning of the life-saving device.

Protective goggles

Beware of splinters. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.

Danger to the youngest

Strictly store magnets away from children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are tragic.

Permanent damage

Regular neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. This process is irreversible.

Serious injuries

Risk of injury: The pulling power is so immense that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.

GPS Danger

An intense magnetic field interferes with the functioning of compasses in smartphones and GPS navigation. Do not bring magnets near a smartphone to prevent damaging the sensors.

Safe operation

Handle with care. Neodymium magnets attract from a distance and snap with massive power, often quicker than you can move away.

Fire risk

Dust produced during cutting of magnets is combustible. Avoid drilling into magnets unless you are an expert.

Metal Allergy

Allergy Notice: The nickel-copper-nickel coating contains nickel. If an allergic reaction appears, immediately stop working with magnets and wear gloves.
