Other products

It is the "heart" of every magnetic filter used in industry for cleaning raw materials. It is mounted in chutes, hoppers, and pipelines to protect production machines from failure. High magnetic induction on the surface allows catching the finest iron particles.
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 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. The economical version (8kGs) handles large pieces of metal perfectly. High Power versions (~12000-14000 Gs) are necessary for catching metallic dust, oxides, and stainless steel after processing.
We can produce a rod of non-standard length with any mounting termination. You can choose a mounting method consistent with your technical design. Contact us for a quote on a non-standard dimension.

Pros and cons of rare earth magnets.

Pros

Besides their remarkable magnetic power, neodymium magnets offer the following advantages:
  • They retain full power for around 10 years – the drop is just ~1% (according to analyses),
  • They possess excellent resistance to magnetism drop as a result of external fields,
  • The use of an metallic layer of noble metals (nickel, gold, silver) causes the element to present itself better,
  • Neodymium magnets achieve maximum magnetic induction on a small area, which ensures high operational effectiveness,
  • Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures approaching 230°C and above...
  • Possibility of detailed forming and optimizing to complex requirements,
  • Universal use in modern industrial fields – they serve a role in computer drives, drive modules, diagnostic systems, and modern systems.
  • Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in miniature devices

Cons

Disadvantages of NdFeB magnets:
  • At strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
  • Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
  • Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
  • Due to limitations in creating nuts and complicated shapes in magnets, we recommend using casing - magnetic mount.
  • Potential hazard resulting from small fragments of magnets can be dangerous, in case of ingestion, which becomes key in the context of child safety. Furthermore, small elements of these magnets can complicate diagnosis medical when they are in the body.
  • High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Pull force analysis

Best holding force of the magnet in ideal parameterswhat affects it?

The load parameter shown concerns the maximum value, measured under ideal test conditions, namely:
  • using a base made of high-permeability steel, serving as a ideal flux conductor
  • whose thickness reaches at least 10 mm
  • characterized by even structure
  • under conditions of gap-free contact (surface-to-surface)
  • during pulling in a direction vertical to the plane
  • at ambient temperature room level

What influences lifting capacity in practice

In real-world applications, the real power is determined by several key aspects, ranked from most significant:
  • Gap between magnet and steel – every millimeter of distance (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
  • Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet holds much less (typically approx. 20-30% of nominal force).
  • Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
  • Material type – ideal substrate is high-permeability steel. Hardened steels may have worse magnetic properties.
  • Base smoothness – the more even the plate, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
  • Thermal factor – high temperature weakens pulling force. Too high temperature can permanently demagnetize the magnet.

Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 5 times. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.

Safe handling of neodymium magnets
Precision electronics

Navigation devices and mobile phones are highly sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the internal compass in your phone.

Avoid contact if allergic

Certain individuals suffer from a contact allergy to nickel, which is the common plating for neodymium magnets. Frequent touching can result in a rash. We suggest wear safety gloves.

Material brittleness

Neodymium magnets are ceramic materials, meaning they are prone to chipping. Collision of two magnets will cause them shattering into small pieces.

Power loss in heat

Avoid heat. NdFeB magnets are susceptible to heat. If you require resistance above 80°C, inquire about special high-temperature series (H, SH, UH).

Caution required

Before starting, check safety instructions. Sudden snapping can break the magnet or injure your hand. Think ahead.

Pinching danger

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

Threat to electronics

Equipment safety: Neodymium magnets can damage data carriers and sensitive devices (heart implants, hearing aids, timepieces).

Adults only

Adult use only. Tiny parts pose a choking risk, leading to severe trauma. Keep away from kids and pets.

Do not drill into magnets

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

Health Danger

Patients with a ICD must maintain an large gap from magnets. The magnetic field can interfere with the functioning of the implant.
