Pulling force

Field Strength

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. 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. A lighter tool allows for longer work without wrist and arm pain. This is a modern solution displacing heavy and weak ferrite magnets.
The neodymium magnet is enclosed in a solid, metal housing (steel or brass). Tool ergonomics are key with frequent use by employees. Thanks to such an armored build, the separator is resistant to difficult conditions prevailing at a scrap yard.
Standard manual separators (such as SMZR 32x175 / 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.

Advantages and disadvantages of Nd2Fe14B magnets.

Benefits

Apart from their consistent holding force, neodymium magnets have these key benefits:
  • Their strength remains stable, and after approximately 10 years it decreases only by ~1% (theoretically),
  • They maintain their magnetic properties even under strong external field,
  • By using a reflective coating of silver, the element acquires an modern look,
  • Magnetic induction on the working part of the magnet remains extremely intense,
  • Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • Considering the ability of flexible molding and customization to custom requirements, magnetic components can be modeled in a wide range of forms and dimensions, which increases their versatility,
  • Universal use in electronics industry – they are used in magnetic memories, electromotive mechanisms, medical equipment, as well as complex engineering applications.
  • Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Cons

Disadvantages of NdFeB magnets:
  • Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a strong case, which not only secures them against impacts but also raises their durability
  • NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
  • Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
  • Due to limitations in realizing threads and complicated shapes in magnets, we recommend using cover - magnetic mount.
  • Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices are able to complicate diagnosis medical after entering the body.
  • Due to neodymium price, their price exceeds standard values,

Lifting parameters

Best holding force of the magnet in ideal parameterswhat affects it?

Breakaway force is the result of a measurement for optimal configuration, taking into account:
  • with the application of a yoke made of special test steel, ensuring maximum field concentration
  • whose transverse dimension reaches at least 10 mm
  • with a plane free of scratches
  • under conditions of ideal adhesion (surface-to-surface)
  • for force acting at a right angle (in the magnet axis)
  • at room temperature

Key elements affecting lifting force

Holding efficiency impacted by working environment parameters, such as (from priority):
  • Distance (between the magnet and the plate), since even a microscopic distance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to paint, rust or debris).
  • Angle of force application – highest force is available only during perpendicular pulling. The force required to slide of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
  • Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
  • Metal type – different alloys attracts identically. High carbon content worsen the attraction effect.
  • Surface finish – ideal contact is possible only on smooth steel. Rough texture reduce the real contact area, reducing force.
  • Temperature – heating the magnet results in weakening of force. Check the maximum operating temperature for a given model.

Lifting capacity testing was performed on a smooth plate of optimal thickness, under a perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. In addition, even a minimal clearance between the magnet and the plate reduces the load capacity.

Warnings
Cards and drives

Powerful magnetic fields can erase data on credit cards, HDDs, and storage devices. Keep a distance of min. 10 cm.

GPS Danger

Remember: rare earth magnets generate a field that interferes with sensitive sensors. Maintain a safe distance from your mobile, device, and navigation systems.

Eye protection

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

Allergy Warning

It is widely known that nickel (standard magnet coating) is a potent allergen. If you have an allergy, avoid touching magnets with bare hands or select versions in plastic housing.

Adults only

Product intended for adults. Small elements can be swallowed, leading to severe trauma. Store out of reach of children and animals.

Pinching danger

Large magnets can crush fingers in a fraction of a second. Never put your hand betwixt two strong magnets.

Immense force

Before starting, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.

Life threat

Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.

Dust is flammable

Fire hazard: Neodymium dust is highly flammable. Do not process magnets in home conditions as this risks ignition.

Operating temperature

Watch the temperature. Exposing the magnet to high heat will permanently weaken its properties and strength.
