Magnetic Induction

Other proposals

A magnetic rod is the basic element of building grate separators and magnetic filters. It is mounted in chutes, hoppers, and pipelines to protect production machines from failure. High magnetic induction on the surface allows catching the finest iron particles.
The construction relies on a sealed, welded stainless steel housing, polished smooth. Inside there is a stack of strong neodymium magnets arranged in a special configuration (magnetic circuit). Thanks to this, the rod is durable, hygienic, and easy to keep clean.
Metal contaminants are strongly attracted, so removing them with a bare hand or glove can be difficult. You can use compressed air or special non-magnetic strippers (rings). For easier operation, it is worth considering ordering a rod in a version with a cleaning sleeve.
The Gauss value tells us how effectively and deeply the magnet will catch contaminants. The economical version (8kGs) handles large pieces of metal perfectly. High induction is necessary when contaminants are microscopic or weakly magnetic.
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. We ensure fast realization of special orders and technical advice.

Pros as well as cons of Nd2Fe14B magnets.

Advantages

In addition to their magnetic capacity, neodymium magnets provide the following advantages:
  • They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (according to literature),
  • Magnets very well resist against loss of magnetization caused by foreign field sources,
  • The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to look better,
  • They are known for high magnetic induction at the operating surface, which affects their effectiveness,
  • 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 precise creating as well as modifying to defined needs,
  • Fundamental importance in electronics industry – they are utilized in mass storage devices, brushless drives, advanced medical instruments, and multitasking production systems.
  • Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which enables their usage in small systems

Disadvantages

Disadvantages of NdFeB magnets:
  • Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a special holder, which not only protects them against impacts but also increases their durability
  • Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
  • They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
  • We suggest casing - magnetic mechanism, due to difficulties in creating threads inside the magnet and complicated shapes.
  • Potential hazard related to microscopic parts of magnets pose a threat, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small elements of these magnets are able to be problematic in diagnostics medical when they are in the body.
  • Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Lifting parameters

Maximum magnetic pulling forcewhat contributes to it?

Magnet power was defined for the most favorable conditions, taking into account:
  • using a plate made of high-permeability steel, acting as a magnetic yoke
  • possessing a thickness of min. 10 mm to avoid saturation
  • with a surface perfectly flat
  • with zero gap (without paint)
  • under axial application of breakaway force (90-degree angle)
  • at room temperature

Practical lifting capacity: influencing factors

Bear in mind that the magnet holding may be lower subject to the following factors, in order of importance:
  • Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
  • Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
  • Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
  • Steel grade – ideal substrate is high-permeability steel. Stainless steels may attract less.
  • Smoothness – ideal contact is obtained only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
  • Thermal environment – heating the magnet results in weakening of force. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity was determined by applying a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under shearing force the load capacity is reduced by as much as 5 times. In addition, even a small distance between the magnet’s surface and the plate reduces the load capacity.

Warnings
Health Danger

Individuals with a heart stimulator have to maintain an absolute distance from magnets. The magnetic field can interfere with the operation of the implant.

Permanent damage

Regular neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. This process is irreversible.

Magnet fragility

Protect your eyes. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. Wear goggles.

GPS Danger

GPS units and mobile phones are extremely sensitive to magnetism. Direct contact with a powerful NdFeB magnet can ruin the sensors in your phone.

Warning for allergy sufferers

Studies show that the nickel plating (the usual finish) is a potent allergen. If your skin reacts to metals, avoid touching magnets with bare hands and select coated magnets.

Data carriers

Avoid bringing magnets near a purse, computer, or TV. The magnetic field can irreversibly ruin these devices and wipe information from cards.

This is not a toy

Product intended for adults. Small elements can be swallowed, causing serious injuries. Store away from children and animals.

Do not underestimate power

Use magnets with awareness. Their immense force can surprise even professionals. Stay alert and do not underestimate their power.

Do not drill into magnets

Fire warning: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this risks ignition.

Hand protection

Big blocks can crush fingers instantly. Under no circumstances put your hand between two strong magnets.
