Magnetic Induction

Other deals

This product serves to effectively catch ferromagnetic contaminants from bulk and liquid products. It is mounted in chutes, hoppers, and pipelines to protect production machines from failure. Thanks to the use of strong neodymium magnets, the rod catches even metallic dust.
The outer layer is hygienic acid-resistant steel, approved for food contact. 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. The most effective home method is using adhesive tape, which we wrap around the dirt and peel off. In industry, cover tubes (so-called Easy Clean system) are used, from which the magnetic insert slides out.
The more Gauss, the smaller and more weakly magnetic particles will be effectively caught. For basic machine protection against pieces of iron, standard power is sufficient. High induction is necessary when contaminants are microscopic or weakly magnetic.
We can produce a rod of non-standard length with any mounting termination. The rod end is strictly adapted to the fastening system in your device. We ensure fast realization of special orders and technical advice.

Strengths as well as weaknesses of neodymium magnets.

Advantages

Besides their durability, neodymium magnets are valued for these benefits:
  • They have unchanged lifting capacity, and over more than 10 years their attraction force decreases symbolically – ~1% (in testing),
  • They are resistant to demagnetization induced by external magnetic fields,
  • A magnet with a metallic gold surface has better aesthetics,
  • Magnetic induction on the working layer of the magnet is exceptional,
  • Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
  • Possibility of custom machining and adjusting to concrete needs,
  • Wide application in high-tech industry – they are utilized in hard drives, motor assemblies, advanced medical instruments, as well as modern systems.
  • Compactness – despite small sizes they generate large force, making them ideal for precision applications

Cons

What to avoid - cons of neodymium magnets and proposals for their use:
  • To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
  • Neodymium magnets lose force 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 extremely 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 immune to moisture, in case of application outdoors
  • We suggest casing - magnetic mount, due to difficulties in realizing threads inside the magnet and complex shapes.
  • Health risk related to microscopic parts of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. Additionally, small components of these devices can complicate diagnosis medical after entering the body.
  • Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

Magnetic strength at its maximum – what affects it?

Magnet power was determined for optimal configuration, including:
  • with the application of a sheet made of special test steel, ensuring full magnetic saturation
  • possessing a massiveness of at least 10 mm to ensure full flux closure
  • with a plane perfectly flat
  • with total lack of distance (without impurities)
  • for force applied at a right angle (in the magnet axis)
  • at room temperature

Practical lifting capacity: influencing factors

Bear in mind that the working load may be lower influenced by the following factors, in order of importance:
  • Space between surfaces – every millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
  • Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
  • Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
  • Material type – ideal substrate is pure iron steel. Cast iron may generate lower lifting capacity.
  • Plate texture – ground elements guarantee perfect abutment, which increases field saturation. Rough surfaces reduce efficiency.
  • Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the load capacity is reduced by as much as 75%. Moreover, even a slight gap between the magnet and the plate lowers the lifting capacity.

Warnings
Product not for children

Only for adults. Tiny parts pose a choking risk, leading to serious injuries. Store away from kids and pets.

Respect the power

Before use, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.

Finger safety

Big blocks can crush fingers instantly. Do not put your hand betwixt two strong magnets.

Electronic devices

Device Safety: Neodymium magnets can ruin payment cards and delicate electronics (pacemakers, medical aids, timepieces).

Do not overheat magnets

Keep cool. Neodymium magnets are sensitive to temperature. If you require resistance above 80°C, look for special high-temperature series (H, SH, UH).

Health Danger

Patients with a heart stimulator should maintain an safe separation from magnets. The magnetic field can interfere with the functioning of the life-saving device.

Magnet fragility

Beware of splinters. Magnets can explode upon violent connection, ejecting sharp fragments into the air. Wear goggles.

Dust explosion hazard

Fire hazard: Neodymium dust is explosive. Do not process magnets in home conditions as this may cause fire.

Warning for allergy sufferers

Certain individuals have a contact allergy to nickel, which is the standard coating for NdFeB magnets. Frequent touching may cause skin redness. We strongly advise use safety gloves.

GPS and phone interference

A powerful magnetic field interferes with the functioning of compasses in phones and GPS navigation. Keep magnets close to a smartphone to prevent breaking the sensors.
