Magnetic Induction

See more products

It is the "heart" of every magnetic filter used in industry for cleaning raw materials. Its task is separation (separation) of metal filings from the transported material. High magnetic induction on the surface allows catching the finest iron particles.
The construction relies on a sealed, welded stainless steel housing, polished smooth. The core is a precise magnetic system generating high induction (Gauss). Thanks to this, the rod is durable, hygienic, and easy to keep clean.
Due to the high power of the magnet, direct removal of filings can be troublesome and time-consuming. We recommend sticking packing tape to the cluster of filings and tearing it off together with the contaminants. For easier operation, it is worth considering ordering a rod in a version with a cleaning sleeve.
Magnetic induction measured in Gauss (Gs) determines the density of magnetic flux on the rod surface. The economical version (8kGs) handles large pieces of metal perfectly. High Power versions (~12000-14000 Gs) are necessary for catching metallic dust, oxides, and stainless steel after processing.
We fulfill individual orders for bars perfectly matched to your machine or separator. We offer various tip options: threaded holes (e.g., M8, M10), protruding screws, flat pivots, mills, or handles. Contact us for a quote on a non-standard dimension.

Strengths as well as weaknesses of Nd2Fe14B magnets.

Pros

Apart from their notable holding force, neodymium magnets have these key benefits:
  • Their strength is durable, and after approximately ten years it drops only by ~1% (theoretically),
  • Magnets very well protect themselves against demagnetization caused by foreign field sources,
  • A magnet with a metallic silver surface has an effective appearance,
  • The surface of neodymium magnets generates a unique magnetic field – this is a distinguishing feature,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
  • Possibility of accurate machining as well as adjusting to complex applications,
  • Key role in high-tech industry – they are commonly used in data components, drive modules, advanced medical instruments, and multitasking production systems.
  • Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Disadvantages

Disadvantages of neodymium magnets:
  • They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
  • Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
  • Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
  • Due to limitations in producing threads and complicated shapes in magnets, we recommend using cover - magnetic mechanism.
  • Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small elements of these magnets are able to complicate diagnosis medical when they are in the body.
  • With budget limitations the cost of neodymium magnets is a challenge,

Lifting parameters

Optimal lifting capacity of a neodymium magnetwhat affects it?

Magnet power is the result of a measurement for the most favorable conditions, including:
  • on a block made of mild steel, effectively closing the magnetic flux
  • possessing a thickness of at least 10 mm to avoid saturation
  • with a surface cleaned and smooth
  • with direct contact (without coatings)
  • for force applied at a right angle (in the magnet axis)
  • in stable room temperature

Practical aspects of lifting capacity – factors

Effective lifting capacity impacted by working environment parameters, such as (from priority):
  • Distance – the presence of foreign body (rust, tape, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
  • Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of nominal force).
  • Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
  • Chemical composition of the base – mild steel gives the best results. Higher carbon content reduce magnetic properties and holding force.
  • Surface structure – the smoother and more polished the plate, the better the adhesion and stronger the hold. Unevenness creates an air distance.
  • Temperature influence – hot environment weakens pulling force. Too high temperature can permanently demagnetize the magnet.

Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, in contrast under parallel forces the holding force is lower. Additionally, even a small distance between the magnet and the plate decreases the load capacity.

Safety rules for work with NdFeB magnets
Nickel allergy

Allergy Notice: The Ni-Cu-Ni coating contains nickel. If skin irritation happens, immediately stop handling magnets and use protective gear.

Heat warning

Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will permanently weaken its properties and strength.

Adults only

Absolutely keep magnets away from children. Ingestion danger is significant, and the effects of magnets clamping inside the body are tragic.

Magnetic media

Do not bring magnets near a wallet, computer, or screen. The magnetism can destroy these devices and erase data from cards.

Threat to navigation

An intense magnetic field disrupts the functioning of magnetometers in phones and GPS navigation. Keep magnets close to a smartphone to avoid breaking the sensors.

Safe operation

Handle with care. Rare earth magnets act from a long distance and connect with huge force, often quicker than you can move away.

Physical harm

Big blocks can smash fingers instantly. Do not place your hand betwixt two strong magnets.

Medical interference

Individuals with a ICD should maintain an large gap from magnets. The magnetism can interfere with the operation of the implant.

Dust explosion hazard

Fire warning: Rare earth powder is highly flammable. Do not process magnets without safety gear as this may cause fire.

Magnet fragility

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