This product serves to effectively catch ferromagnetic contaminants from bulk and liquid products. Its task is separation (separation) of metal filings from the transported material. 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. 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. For basic machine protection against pieces of iron, standard power is sufficient. 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.

Strengths and weaknesses of Nd2Fe14B magnets.

Pros

Apart from their superior power, neodymium magnets have these key benefits:
  • Their magnetic field is durable, and after approximately 10 years it decreases only by ~1% (theoretically),
  • Neodymium magnets are distinguished by highly resistant to demagnetization caused by external field sources,
  • The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
  • Magnets have very high magnetic induction on the outer side,
  • Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
  • Considering the option of precise forming and adaptation to specialized needs, neodymium magnets can be modeled in a broad palette of shapes and sizes, which makes them more universal,
  • Key role in modern technologies – they are utilized in hard drives, drive modules, advanced medical instruments, and complex engineering applications.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Weaknesses

Disadvantages of neodymium magnets:
  • To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
  • When exposed to high temperature, neodymium magnets suffer 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 oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
  • We suggest a housing - magnetic mount, due to difficulties in realizing threads inside the magnet and complicated shapes.
  • Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. Additionally, small elements of these products are able to disrupt the diagnostic process medical when they are in the body.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Pull force analysis

Breakaway strength of the magnet in ideal conditionswhat affects it?

Information about lifting capacity is the result of a measurement for the most favorable conditions, assuming:
  • using a base made of low-carbon steel, serving as a magnetic yoke
  • possessing a thickness of min. 10 mm to ensure full flux closure
  • with a plane free of scratches
  • without the slightest insulating layer between the magnet and steel
  • under perpendicular force direction (90-degree angle)
  • in stable room temperature

Lifting capacity in real conditions – factors

Please note that the magnet holding will differ influenced by elements below, in order of importance:
  • Clearance – existence of any layer (rust, dirt, air) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
  • Force direction – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of maximum force).
  • Base massiveness – too thin steel causes magnetic saturation, causing part of the flux to be wasted to the other side.
  • Steel grade – ideal substrate is high-permeability steel. Stainless steels may have worse magnetic properties.
  • Base smoothness – the more even the plate, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
  • Thermal factor – high temperature weakens magnetic field. Too high temperature can permanently demagnetize the magnet.

Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate decreases the holding force.

Warnings
Do not drill into magnets

Combustion risk: Rare earth powder is explosive. Avoid machining magnets without safety gear as this may cause fire.

Adults only

Adult use only. Tiny parts pose a choking risk, leading to severe trauma. Store out of reach of children and animals.

Medical implants

Patients with a heart stimulator must maintain an large gap from magnets. The magnetic field can stop the operation of the life-saving device.

Power loss in heat

Do not overheat. NdFeB magnets are susceptible to temperature. If you require resistance above 80°C, inquire about special high-temperature series (H, SH, UH).

Nickel allergy

A percentage of the population experience a contact allergy to nickel, which is the standard coating for neodymium magnets. Prolonged contact can result in dermatitis. We recommend use protective gloves.

Beware of splinters

Despite metallic appearance, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.

Threat to navigation

Note: neodymium magnets produce a field that interferes with sensitive sensors. Keep a safe distance from your phone, device, and navigation systems.

Immense force

Handle magnets with awareness. Their powerful strength can shock even professionals. Plan your moves and do not underestimate their force.

Threat to electronics

Very strong magnetic fields can destroy records on credit cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.

Serious injuries

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