Field Strength

Other deals

This gripper serves for instant distinction of steel (iron) from non-ferrous metals. It allows checking if a given item is ferromagnetic (steel, cast iron) or not (aluminum, copper, stainless steel). 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. Lack of reaction (attraction) means the tested item is made of non-magnetic material.
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. Thanks to such an armored build, the separator is resistant to difficult conditions prevailing at a scrap yard.
Standard manual separators (such as SMZR 32x100 / N52) do not have a release mechanism and require manual cleaning. Models with a release lever (so-called grippers with a dropper) are also available in another category. 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.

Strengths as well as weaknesses of rare earth magnets.

Benefits

In addition to their magnetic capacity, neodymium magnets provide the following advantages:
  • They retain full power for nearly 10 years – the drop is just ~1% (in theory),
  • Neodymium magnets are exceptionally resistant to loss of magnetic properties caused by magnetic disturbances,
  • The use of an refined layer of noble metals (nickel, gold, silver) causes the element to look better,
  • Magnetic induction on the working part of the magnet turns out to be maximum,
  • Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures approaching 230°C and above...
  • Possibility of accurate shaping and adapting to specific requirements,
  • Significant place in innovative solutions – they are commonly used in magnetic memories, motor assemblies, medical equipment, and other advanced devices.
  • Compactness – despite small sizes they generate large force, making them ideal for precision applications

Limitations

Drawbacks and weaknesses of neodymium magnets and ways of using them
  • To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
  • We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
  • Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
  • Limited ability of creating threads in the magnet and complicated shapes - preferred is a housing - magnetic holder.
  • Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the aspect of protecting the youngest. Additionally, small elements of these products can complicate diagnosis medical when they are in the body.
  • With mass production the cost of neodymium magnets can be a barrier,

Pull force analysis

Highest magnetic holding forcewhat contributes to it?

The specified lifting capacity refers to the maximum value, measured under laboratory conditions, specifically:
  • with the use of a yoke made of special test steel, ensuring maximum field concentration
  • with a thickness of at least 10 mm
  • with an polished touching surface
  • with zero gap (no paint)
  • under axial force direction (90-degree angle)
  • at temperature room level

Determinants of practical lifting force of a magnet

Real force impacted by working environment parameters, including (from most important):
  • Gap between magnet and steel – every millimeter of separation (caused e.g. by veneer or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
  • Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
  • Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
  • Steel type – low-carbon steel gives the best results. Higher carbon content decrease magnetic permeability and holding force.
  • Surface finish – ideal contact is possible only on smooth steel. Rough texture create air cushions, reducing force.
  • Thermal factor – hot environment reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity was assessed using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under parallel forces the load capacity is reduced by as much as fivefold. Moreover, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.

Safe handling of neodymium magnets
This is not a toy

Adult use only. Small elements can be swallowed, causing serious injuries. Store out of reach of kids and pets.

Skin irritation risks

Allergy Notice: The Ni-Cu-Ni coating contains nickel. If redness occurs, immediately stop working with magnets and use protective gear.

Material brittleness

Despite metallic appearance, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.

Bone fractures

Protect your hands. Two powerful magnets will snap together instantly with a force of massive weight, crushing everything in their path. Exercise extreme caution!

Mechanical processing

Mechanical processing of neodymium magnets carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Implant safety

Individuals with a heart stimulator must keep an large gap from magnets. The magnetism can stop the functioning of the implant.

Protect data

Do not bring magnets near a purse, computer, or TV. The magnetic field can permanently damage these devices and erase data from cards.

Handling guide

Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.

Magnetic interference

Note: neodymium magnets produce a field that interferes with precision electronics. Maintain a safe distance from your mobile, tablet, and GPS.

Power loss in heat

Avoid heat. NdFeB magnets are sensitive to temperature. If you need operation above 80°C, ask us about special high-temperature series (H, SH, UH).
