Magnetic Induction

See also products

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. Thanks to the use of strong neodymium magnets, the rod catches even metallic dust.
The construction relies on a sealed, welded stainless steel housing, polished smooth. The core is a precise magnetic system generating high induction (Gauss). Such construction ensures full resistance to corrosion, water, oils, and acids.
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). 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. Standard rods (~8000 Gs) are sufficient for catching screws, nails, and steel shavings. 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). The rod end is strictly adapted to the fastening system in your device. Contact us for a quote on a non-standard dimension.

Advantages and disadvantages of neodymium magnets.

Strengths

Besides their remarkable pulling force, neodymium magnets offer the following advantages:
  • They virtually do not lose power, because even after ten years the performance loss is only ~1% (based on calculations),
  • They do not lose their magnetic properties even under external field action,
  • In other words, due to the metallic surface of silver, the element gains a professional look,
  • Magnetic induction on the top side of the magnet is extremely intense,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
  • Thanks to the possibility of flexible forming and adaptation to unique requirements, neodymium magnets can be created in a variety of forms and dimensions, which amplifies use scope,
  • Significant place in modern industrial fields – they are utilized in data components, drive modules, precision medical tools, also multitasking production systems.
  • Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which allows their use in small systems

Cons

Disadvantages of neodymium magnets:
  • They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
  • When exposed to high temperature, neodymium magnets suffer a drop in power. 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 - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • Due to limitations in producing nuts and complex shapes in magnets, we propose using a housing - magnetic mechanism.
  • Potential hazard related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. Additionally, small elements of these products can be problematic in diagnostics medical after entering the body.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Holding force characteristics

Optimal lifting capacity of a neodymium magnetwhat it depends on?

The force parameter is a result of laboratory testing conducted under the following configuration:
  • using a sheet made of high-permeability steel, functioning as a magnetic yoke
  • with a thickness no less than 10 mm
  • with a surface perfectly flat
  • under conditions of ideal adhesion (surface-to-surface)
  • for force applied at a right angle (in the magnet axis)
  • at ambient temperature room level

Practical lifting capacity: influencing factors

Holding efficiency impacted by working environment parameters, including (from most important):
  • Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, 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 significantly, often to levels of 20-30% of the nominal value.
  • Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
  • Metal type – different alloys reacts the same. High carbon content worsen the attraction effect.
  • Surface finish – ideal contact is obtained only on smooth steel. Rough texture reduce the real contact area, reducing force.
  • Thermal factor – high temperature reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.

Warnings
Protective goggles

Despite the nickel coating, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.

Power loss in heat

Keep cool. NdFeB magnets are sensitive to temperature. If you require operation above 80°C, ask us about special high-temperature series (H, SH, UH).

Powerful field

Exercise caution. Rare earth magnets act from a distance and snap with huge force, often faster than you can react.

Serious injuries

Protect your hands. Two powerful magnets will snap together immediately with a force of several hundred kilograms, destroying everything in their path. Be careful!

Magnetic interference

Remember: rare earth magnets generate a field that disrupts precision electronics. Keep a safe distance from your mobile, device, and navigation systems.

Dust is flammable

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

Keep away from children

Strictly store magnets away from children. Ingestion danger is high, and the effects of magnets connecting inside the body are life-threatening.

Skin irritation risks

Certain individuals have a sensitization to nickel, which is the common plating for neodymium magnets. Frequent touching might lead to dermatitis. We suggest use protective gloves.

Protect data

Powerful magnetic fields can erase data on payment cards, hard drives, and storage devices. Keep a distance of at least 10 cm.

Health Danger

Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
