Field Strength

Other products

It is the "heart" of every magnetic filter used in industry for cleaning raw materials. Its task is separation (separation) of metal filings from the transported material. 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). Such construction ensures full resistance to corrosion, water, oils, and acids.
Metal filings stick to the surface very strongly, so cleaning requires strength or cleverness. The most effective home method is using adhesive tape, which we wrap around the dirt and peel off. For easier operation, it is worth considering ordering a rod in a version with a cleaning sleeve.
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 fulfill individual orders for bars perfectly matched to your machine or separator. 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 as well as cons of neodymium magnets.

Advantages
Besides their stability, neodymium magnets are valued for these benefits:
  • They do not lose magnetism, even over around ten years – the reduction in lifting capacity is only ~1% (according to tests),
  • Magnets perfectly resist against demagnetization caused by ambient magnetic noise,
  • By using a decorative coating of nickel, the element acquires an elegant look,
  • Neodymium magnets ensure maximum magnetic induction on a small surface, which ensures high operational effectiveness,
  • Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
  • Considering the option of precise molding and adaptation to individualized needs, NdFeB magnets can be created in a variety of forms and dimensions, which expands the range of possible applications,
  • Fundamental importance in high-tech industry – they serve a role in data components, motor assemblies, diagnostic systems, as well as industrial machines.
  • Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Disadvantages
Cons of neodymium magnets: tips and applications.
  • They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
  • 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 and 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 stable to moisture, in case of application outdoors
  • We recommend casing - magnetic holder, due to difficulties in creating nuts inside the magnet and complicated forms.
  • Health risk related to microscopic parts of magnets are risky, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices are able to complicate diagnosis medical in case of swallowing.
  • With budget limitations the cost of neodymium magnets is economically unviable,

Holding force characteristics

Highest magnetic holding forcewhat it depends on?
The load parameter shown concerns the peak performance, measured under optimal environment, meaning:
  • using a sheet made of mild steel, functioning as a magnetic yoke
  • with a cross-section minimum 10 mm
  • with an polished contact surface
  • without any clearance between the magnet and steel
  • under vertical force vector (90-degree angle)
  • in temp. approx. 20°C
Key elements affecting lifting force
Holding efficiency is influenced by working environment parameters, such as (from most important):
  • Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
  • Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of nominal force).
  • Base massiveness – insufficiently thick steel does not accept the full field, causing part of the flux to be lost to the other side.
  • Metal type – not every steel attracts identically. Alloy additives worsen the interaction with the magnet.
  • Plate texture – smooth surfaces guarantee perfect abutment, which improves force. Uneven metal weaken the grip.
  • Temperature – heating the magnet causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate decreases the holding force.

Safe handling of neodymium magnets
Implant safety

Warning for patients: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or ask another person to handle the magnets.

Do not overheat magnets

Standard neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. The loss of strength is permanent.

No play value

Only for adults. Tiny parts can be swallowed, causing intestinal necrosis. Keep away from children and animals.

GPS Danger

Be aware: rare earth magnets produce a field that disrupts sensitive sensors. Keep a separation from your mobile, tablet, and navigation systems.

Magnets are brittle

Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Wear goggles.

Powerful field

Use magnets consciously. Their immense force can surprise even experienced users. Be vigilant and do not underestimate their power.

Fire warning

Dust produced during machining of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.

Nickel allergy

Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If skin irritation occurs, cease working with magnets and use protective gear.

Crushing risk

Mind your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!

Protect data

Data protection: Neodymium magnets can damage payment cards and sensitive devices (pacemakers, medical aids, mechanical watches).
