Magnetic Induction

See also offers

This product serves to effectively catch ferromagnetic contaminants from bulk and liquid products. It is commonly used for cleaning flour, sugar, plastic granules, as well as oils and coolants. High magnetic induction on the surface allows catching the finest iron particles.
The outer layer is hygienic acid-resistant steel, approved for food contact. 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 filings stick to the surface very strongly, so cleaning requires strength or cleverness. We recommend sticking packing tape to the cluster of filings and tearing it off together with the contaminants. 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. For the food and precision industry, we recommend the highest induction parameters.
We can produce a rod of non-standard length with any mounting termination. 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.

Pros and cons of rare earth magnets.

Advantages

In addition to their long-term stability, neodymium magnets provide the following advantages:
  • They retain full power for almost 10 years – the loss is just ~1% (in theory),
  • They are extremely resistant to demagnetization induced by external disturbances,
  • In other words, due to the reflective finish of nickel, the element gains a professional look,
  • They feature high magnetic induction at the operating surface, making them more effective,
  • Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures approaching 230°C and above...
  • Possibility of precise creating as well as optimizing to complex needs,
  • Significant place in electronics industry – they serve a role in HDD drives, electric drive systems, diagnostic systems, as well as modern systems.
  • Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Weaknesses

Disadvantages of neodymium magnets:
  • They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
  • Neodymium magnets demagnetize 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 very 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
  • Due to limitations in realizing threads and complicated shapes in magnets, we propose using casing - magnetic holder.
  • Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. Furthermore, small components of these magnets are able to complicate diagnosis medical in case of swallowing.
  • High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities

Pull force analysis

Maximum lifting capacity of the magnetwhat it depends on?

Information about lifting capacity was defined for optimal configuration, taking into account:
  • using a sheet made of low-carbon steel, serving as a magnetic yoke
  • whose transverse dimension reaches at least 10 mm
  • with a plane cleaned and smooth
  • with direct contact (without coatings)
  • for force acting at a right angle (in the magnet axis)
  • at room temperature

Practical lifting capacity: influencing factors

Real force impacted by specific conditions, such as (from most important):
  • Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
  • Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
  • Base massiveness – insufficiently thick plate causes magnetic saturation, causing part of the flux to be lost into the air.
  • Material type – ideal substrate is high-permeability steel. Hardened steels may have worse magnetic properties.
  • Smoothness – ideal contact is possible only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
  • Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet’s surface and the plate decreases the holding force.

Safe handling of neodymium magnets
Eye protection

Despite the nickel coating, the material is delicate and not impact-resistant. Do not hit, as the magnet may shatter into hazardous fragments.

Electronic hazard

Device Safety: Neodymium magnets can ruin payment cards and delicate electronics (heart implants, medical aids, mechanical watches).

Do not give to children

Strictly keep magnets out of reach of children. Ingestion danger is high, and the consequences of magnets clamping inside the body are fatal.

Serious injuries

Danger of trauma: The attraction force is so immense that it can cause blood blisters, crushing, and broken bones. Protective gloves are recommended.

Warning for allergy sufferers

Certain individuals suffer from a hypersensitivity to nickel, which is the common plating for neodymium magnets. Extended handling might lead to skin redness. We recommend use protective gloves.

Health Danger

Warning for patients: Strong magnetic fields affect electronics. Maintain at least 30 cm distance or request help to work with the magnets.

Machining danger

Powder created during machining of magnets is self-igniting. Do not drill into magnets unless you are an expert.

Heat sensitivity

Keep cool. Neodymium magnets are sensitive to heat. If you need operation above 80°C, inquire about HT versions (H, SH, UH).

GPS Danger

GPS units and smartphones are extremely sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can permanently damage the sensors in your phone.

Safe operation

Handle with care. Rare earth magnets attract from a long distance and snap with massive power, often faster than you can react.
