It is an essential at every scrap yard, waste sorting plant, and workshop. It allows checking if a given item is ferromagnetic (steel, cast iron) or not (aluminum, copper, stainless steel). It can be used to collect scattered nails and screws from hard-to-reach places.

The magnet "catches" iron but remains completely indifferent to aluminum, copper, brass, and zinc. Lack of reaction (attraction) means the tested item is made of non-magnetic material.

The neodymium model offers powerful force with low weight, which drastically reduces hand fatigue. Thanks to this, work is more comfortable, and detection faster and more certain. The neodymium version is currently the standard in professional scrap yards.

The magnet is completely shielded from mechanical impacts, which extends its lifespan. A solid handle (wooden, rubber, or plastic) ensures a firm and comfortable grip. Thanks to such an armored build, the separator is resistant to difficult conditions prevailing at a scrap yard.

Standard manual separators (such as SMZR 32x225 / N52) do not have a release mechanism and require manual cleaning. We also offer versions where pulling the handle automatically drops collected material. The sliding technique is more effective and requires less force than perpendicular tearing.

Strengths as well as weaknesses of rare earth magnets.

Advantages

Apart from their strong power, neodymium magnets have these key benefits:

They have unchanged lifting capacity, and over around 10 years their performance decreases symbolically – ~1% (according to theory),
They feature excellent resistance to magnetic field loss as a result of external magnetic sources,
The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to present itself better,
Magnets are distinguished by excellent magnetic induction on the surface,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
Considering the option of flexible shaping and adaptation to individualized projects, neodymium magnets can be created in a broad palette of shapes and sizes, which expands the range of possible applications,
Wide application in electronics industry – they serve a role in data components, brushless drives, precision medical tools, and modern systems.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in miniature devices

Cons

Characteristics of disadvantages of neodymium magnets: application proposals

They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. 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 stable to moisture, in case of application outdoors
We suggest casing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complicated forms.
Possible danger related to microscopic parts of magnets are risky, when accidentally swallowed, which becomes key in the context of child health protection. Furthermore, small components of these devices can disrupt the diagnostic process medical after entering the body.
Due to expensive raw materials, their price is higher than average,

Lifting parameters

Maximum holding power of the magnet – what it depends on?

Holding force of 0.00 kg is a result of laboratory testing conducted under standard conditions:

with the use of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
with a cross-section minimum 10 mm
with a plane cleaned and smooth
without the slightest clearance between the magnet and steel
for force applied at a right angle (pull-off, not shear)
at ambient temperature approx. 20 degrees Celsius

What influences lifting capacity in practice

In real-world applications, the actual holding force results from several key aspects, presented from most significant:

Distance – the presence of any layer (rust, dirt, gap) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
Direction of force – highest force is obtained only during perpendicular pulling. The force required to slide of the magnet along the surface is standardly several times smaller (approx. 1/5 of the lifting capacity).
Steel thickness – too thin steel causes magnetic saturation, causing part of the flux to be escaped to the other side.
Steel grade – the best choice is high-permeability steel. Cast iron may have worse magnetic properties.
Plate texture – smooth surfaces ensure maximum contact, which increases field saturation. Uneven metal weaken the grip.
Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).

Lifting capacity was determined with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under parallel forces the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate reduces the holding force.

Safe handling of NdFeB magnets

Nickel coating and allergies

Some people suffer from a sensitization to Ni, which is the typical protective layer for neodymium magnets. Frequent touching might lead to dermatitis. It is best to wear protective gloves.

Demagnetization risk

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

Pacemakers

Patients with a heart stimulator should keep an absolute distance from magnets. The magnetic field can disrupt the functioning of the implant.

Choking Hazard

These products are not toys. Swallowing a few magnets can lead to them pinching intestinal walls, which constitutes a critical condition and requires urgent medical intervention.

Do not underestimate power

Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.

Fire warning

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

Fragile material

Protect your eyes. Magnets can explode upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.

Safe distance

Intense magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Maintain a gap of min. 10 cm.

Keep away from electronics

An intense magnetic field negatively affects the operation of compasses in smartphones and GPS navigation. Do not bring magnets near a device to prevent breaking the sensors.

Crushing force

Pinching hazard: The attraction force is so great that it can cause hematomas, crushing, and broken bones. Use thick gloves.
