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. 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 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. 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 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.

Advantages as well as disadvantages of rare earth magnets.

Advantages

Besides their durability, neodymium magnets are valued for these benefits:

Their strength is maintained, and after approximately 10 years it drops only by ~1% (theoretically),
They maintain their magnetic properties even under close interference source,
A magnet with a metallic silver surface looks better,
They show high magnetic induction at the operating surface, which affects their effectiveness,
Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
Possibility of custom machining and modifying to individual needs,
Key role in high-tech industry – they are commonly used in hard drives, electric drive systems, precision medical tools, also multitasking production systems.
Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which makes them useful in small systems

Cons

Cons of neodymium magnets: application proposals

Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only secures them against impacts but also raises their durability
NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (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 suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
Due to limitations in realizing nuts and complicated shapes in magnets, we propose using casing - magnetic mount.
Possible danger to health – tiny shards of magnets are risky, in case of ingestion, which becomes key in the aspect of protecting the youngest. It is also worth noting that small elements of these products are able to be problematic in diagnostics medical after entering the body.
With budget limitations the cost of neodymium magnets is economically unviable,

Pull force analysis

Highest magnetic holding force – what contributes to it?

The lifting capacity listed is a measurement result conducted under standard conditions:

using a base made of high-permeability steel, serving as a ideal flux conductor
with a thickness minimum 10 mm
with a surface free of scratches
without the slightest clearance between the magnet and steel
during detachment in a direction vertical to the mounting surface
in neutral thermal conditions

Determinants of lifting force in real conditions

In real-world applications, the real power is determined by several key aspects, listed from the most important:

Space between magnet and steel – every millimeter of distance (caused e.g. by veneer or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
Base massiveness – insufficiently thick steel does not close the flux, causing part of the power to be wasted into the air.
Material composition – not every steel reacts the same. Alloy additives weaken the interaction with the magnet.
Surface condition – ground elements ensure maximum contact, which improves force. Rough surfaces reduce efficiency.
Operating temperature – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity was assessed using a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under shearing force the holding force is lower. In addition, even a slight gap between the magnet and the plate decreases the lifting capacity.

Precautions when working with NdFeB magnets

Medical interference

People with a pacemaker have to keep an large gap from magnets. The magnetic field can disrupt the operation of the implant.

Dust explosion hazard

Drilling and cutting of NdFeB material poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.

Sensitization to coating

Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If skin irritation occurs, immediately stop working with magnets and wear gloves.

Operating temperature

Watch the temperature. Heating the magnet to high heat will permanently weaken its properties and pulling force.

GPS and phone interference

Remember: neodymium magnets produce a field that confuses precision electronics. Maintain a separation from your phone, device, and navigation systems.

Eye protection

Despite metallic appearance, the material is brittle and not impact-resistant. Do not hit, as the magnet may shatter into hazardous fragments.

Cards and drives

Equipment safety: Strong magnets can ruin payment cards and sensitive devices (pacemakers, hearing aids, mechanical watches).

Conscious usage

Exercise caution. Neodymium magnets act from a distance and connect with huge force, often quicker than you can move away.

Hand protection

Protect your hands. Two large magnets will join instantly with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!

Danger to the youngest

NdFeB magnets are not toys. Eating several magnets may result in them pinching intestinal walls, which poses a direct threat to life and necessitates immediate surgery.

Caution! Learn more about risks in the article: Magnet Safety Guide.
