Magnetic Field

Other proposals

It is the "heart" of every magnetic filter used in industry for cleaning raw materials. 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.
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. For the food and precision industry, we recommend the highest induction parameters.
Yes, as a manufacturer, we make rods of any length and diameter (standard is dia 25mm and 32mm). You can choose a mounting method consistent with your technical design. Contact us for a quote on a non-standard dimension.

Advantages as well as disadvantages of Nd2Fe14B magnets.

Pros

Besides their tremendous magnetic power, neodymium magnets offer the following advantages:
  • They have stable power, and over around ten years their attraction force decreases symbolically – ~1% (in testing),
  • Magnets perfectly defend themselves against loss of magnetization caused by ambient magnetic noise,
  • By applying a smooth coating of gold, the element presents an aesthetic look,
  • Neodymium magnets deliver maximum magnetic induction on a small surface, which increases force concentration,
  • 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...
  • In view of the option of free shaping and adaptation to specialized solutions, magnetic components can be produced in a variety of shapes and sizes, which increases their versatility,
  • Significant place in electronics industry – they are used in HDD drives, brushless drives, medical equipment, and other advanced devices.
  • Thanks to their power density, small magnets offer high operating force, with minimal size,

Disadvantages

Disadvantages of neodymium magnets:
  • To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
  • When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • Due to limitations in realizing threads and complex forms in magnets, we recommend using casing - magnetic mount.
  • Health risk related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, tiny parts of these products can disrupt the diagnostic process medical when they are in the body.
  • Due to complex production process, their price is higher than average,

Holding force characteristics

Magnetic strength at its maximum – what affects it?

The declared magnet strength refers to the limit force, obtained under ideal test conditions, meaning:
  • on a plate made of structural steel, effectively closing the magnetic flux
  • whose thickness equals approx. 10 mm
  • with a plane free of scratches
  • without the slightest insulating layer between the magnet and steel
  • during detachment in a direction vertical to the mounting surface
  • at temperature approx. 20 degrees Celsius

Determinants of lifting force in real conditions

In practice, the real power depends on several key aspects, ranked from crucial:
  • Air gap (between the magnet and the plate), because even a tiny distance (e.g. 0.5 mm) can cause a reduction in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
  • Load vector – maximum parameter is available only during pulling at a 90° angle. The shear force of the magnet along the surface is standardly many times lower (approx. 1/5 of the lifting capacity).
  • Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
  • Steel grade – the best choice is high-permeability steel. Hardened steels may attract less.
  • Surface condition – ground elements guarantee perfect abutment, which increases field saturation. Uneven metal reduce efficiency.
  • Temperature – temperature increase results in weakening of force. Check the thermal limit for a given model.

Lifting capacity was assessed by applying a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under attempts to slide the magnet the holding force is lower. Moreover, even a minimal clearance between the magnet and the plate decreases the load capacity.

Warnings
Dust explosion hazard

Mechanical processing of neodymium magnets carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.

Magnetic media

Data protection: Strong magnets can ruin data carriers and delicate electronics (pacemakers, hearing aids, mechanical watches).

Sensitization to coating

Studies show that nickel (the usual finish) is a strong allergen. For allergy sufferers, avoid touching magnets with bare hands or opt for versions in plastic housing.

Compass and GPS

Navigation devices and mobile phones are highly susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the sensors in your phone.

Adults only

Product intended for adults. Small elements pose a choking risk, causing severe trauma. Store away from children and animals.

Beware of splinters

Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.

Finger safety

Mind your fingers. Two powerful magnets will join immediately with a force of massive weight, destroying everything in their path. Be careful!

Danger to pacemakers

Warning for patients: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or request help to work with the magnets.

Do not underestimate power

Before starting, read the rules. Sudden snapping can destroy the magnet or injure your hand. Think ahead.

Heat sensitivity

Regular neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.
