A magnetic rod is the basic element of building grate separators and magnetic filters. 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 center is filled with NdFeB magnets and pole pieces, arranged to maximize the field on the tube surface. Such construction ensures full resistance to corrosion, water, oils, and acids.

Due to the high power of the magnet, direct removal of filings can be troublesome and time-consuming. The most effective home method is using adhesive tape, which we wrap around the dirt and peel off. 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. 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. We ensure fast realization of special orders and technical advice.

Strengths as well as weaknesses of rare earth magnets.

Benefits

Apart from their consistent magnetic energy, neodymium magnets have these key benefits:

They have constant strength, and over more than 10 years their performance decreases symbolically – ~1% (according to theory),
Neodymium magnets prove to be exceptionally resistant to magnetic field loss caused by external magnetic fields,
A magnet with a shiny silver surface is more attractive,
Magnets have maximum magnetic induction on the surface,
Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
Possibility of precise machining as well as optimizing to individual needs,
Versatile presence in modern technologies – they serve a role in hard drives, electric motors, medical equipment, as well as modern systems.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Cons

Disadvantages of neodymium magnets:

They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 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 stable to moisture, in case of application outdoors
We recommend casing - magnetic mount, due to difficulties in realizing nuts inside the magnet and complicated forms.
Possible danger to health – tiny shards of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these magnets can complicate diagnosis medical after entering the body.
Due to expensive raw materials, their price exceeds standard values,

Lifting parameters

Maximum holding power of the magnet – what affects it?

Breakaway force is the result of a measurement for ideal contact conditions, assuming:

on a plate made of mild steel, optimally conducting the magnetic field
possessing a massiveness of minimum 10 mm to avoid saturation
with an polished touching surface
under conditions of ideal adhesion (surface-to-surface)
for force acting at a right angle (in the magnet axis)
at room temperature

Magnet lifting force in use – key factors

Holding efficiency is affected by specific conditions, mainly (from most important):

Space between surfaces – every millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
Force direction – catalog parameter refers to pulling vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of maximum force).
Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
Material type – ideal substrate is pure iron steel. Hardened steels may have worse magnetic properties.
Surface finish – ideal contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
Thermal factor – high temperature reduces magnetic field. Too high temperature can permanently demagnetize the magnet.

Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate decreases the holding force.

Precautions when working with NdFeB magnets

Powerful field

Be careful. Neodymium magnets attract from a distance and connect with huge force, often faster than you can move away.

Choking Hazard

NdFeB magnets are not suitable for play. Swallowing a few magnets can lead to them connecting inside the digestive tract, which constitutes a severe health hazard and requires immediate surgery.

Do not overheat magnets

Regular neodymium magnets (grade N) undergo demagnetization when the temperature exceeds 80°C. Damage is permanent.

Electronic hazard

Do not bring magnets near a wallet, laptop, or TV. The magnetism can destroy these devices and wipe information from cards.

Risk of cracking

NdFeB magnets are ceramic materials, meaning they are prone to chipping. Collision of two magnets will cause them cracking into shards.

Dust explosion hazard

Combustion risk: Neodymium dust is explosive. Do not process magnets in home conditions as this risks ignition.

GPS Danger

A powerful magnetic field disrupts the operation of magnetometers in smartphones and GPS navigation. Maintain magnets close to a device to prevent damaging the sensors.

Crushing force

Large magnets can smash fingers in a fraction of a second. Under no circumstances place your hand betwixt two strong magnets.

Medical interference

Warning for patients: Powerful magnets affect medical devices. Maintain minimum 30 cm distance or ask another person to work with the magnets.

Warning for allergy sufferers

Allergy Notice: The nickel-copper-nickel coating consists of nickel. If skin irritation happens, immediately stop handling magnets and use protective gear.
