Shopping tips

The offered product is an extremely powerful rod magnet, composed of modern NdFeB material, which, with dimensions of Ø6x2 mm, guarantees maximum efficiency. This specific item boasts high dimensional repeatability and industrial build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with significant force (approx. 0.66 kg), this product is in stock from our warehouse in Poland, ensuring lightning-fast order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.
This model is ideal for building electric motors, advanced sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the pull force of 6.47 N with a weight of only 0.42 g, this rod is indispensable in miniature devices and wherever low weight is crucial.
Since our magnets have a tolerance of ±0.1mm, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 6.1 mm) using two-component epoxy glues. To ensure long-term durability in industry, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.
Grade N38 is the most frequently chosen standard for industrial neodymium magnets, offering an optimal price-to-power ratio and high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø6x2), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.
This model is characterized by dimensions Ø6x2 mm, which, at a weight of 0.42 g, makes it an element with impressive magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 0.66 kg (force ~6.47 N), which, with such compact dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which secures it against oxidation, giving it an aesthetic, silvery shine.
This rod magnet is magnetized axially (along the height of 2 mm), which means that the N and S poles are located on the flat, circular surfaces. Thanks to this, the magnet can be easily glued into a hole and achieve a strong field on the front surface. On request, we can also produce versions magnetized diametrically if your project requires it.

Advantages and disadvantages of neodymium magnets.

Besides their high retention, neodymium magnets are valued for these benefits:

  • They do not lose magnetism, even during nearly ten years – the reduction in strength is only ~1% (theoretically),
  • Magnets perfectly defend themselves against loss of magnetization caused by external fields,
  • Thanks to the shiny finish, the coating of Ni-Cu-Ni, gold, or silver gives an elegant appearance,
  • The surface of neodymium magnets generates a powerful magnetic field – this is a distinguishing feature,
  • Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
  • Thanks to flexibility in designing and the ability to modify to complex applications,
  • Fundamental importance in electronics industry – they serve a role in magnetic memories, drive modules, medical devices, and technologically advanced constructions.
  • Compactness – despite small sizes they provide effective action, making them ideal for precision applications

What to avoid - cons of neodymium magnets and ways of using them

  • At strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • Neodymium magnets lose their power 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 stability even at temperatures up to 230°C
  • Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
  • Due to limitations in creating threads and complicated shapes in magnets, we propose using casing - magnetic holder.
  • Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small elements of these devices are able to disrupt the diagnostic process medical when they are in the body.
  • High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities

Maximum lifting capacity of the magnetwhat affects it?

The declared magnet strength concerns the limit force, measured under ideal test conditions, namely:

  • on a block made of structural steel, perfectly concentrating the magnetic flux
  • whose thickness reaches at least 10 mm
  • with an ideally smooth contact surface
  • under conditions of ideal adhesion (surface-to-surface)
  • during detachment in a direction vertical to the mounting surface
  • at temperature room level

Practical aspects of lifting capacity – factors

In real-world applications, the actual holding force is determined by a number of factors, ranked from most significant:

  • Distance – the presence of any layer (paint, dirt, gap) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
  • Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
  • Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
  • Plate material – low-carbon steel gives the best results. Alloy steels reduce magnetic permeability and holding force.
  • Base smoothness – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
  • Temperature – heating the magnet results in weakening of force. Check the maximum operating temperature for a given model.

* Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the holding force is lower. In addition, even a minimal clearance {between} the magnet and the plate reduces the lifting capacity.

H&S for magnets

Finger safety

Pinching hazard: The pulling power is so great that it can cause blood blisters, pinching, and broken bones. Use thick gloves.

Do not overheat magnets

Watch the temperature. Exposing the magnet to high heat will destroy its magnetic structure and pulling force.

Adults only

Absolutely keep magnets away from children. Risk of swallowing is significant, and the effects of magnets connecting inside the body are tragic.

Threat to navigation

Remember: neodymium magnets produce a field that interferes with sensitive sensors. Keep a safe distance from your phone, device, and navigation systems.

Electronic devices

Avoid bringing magnets near a wallet, computer, or screen. The magnetism can permanently damage these devices and wipe information from cards.

Conscious usage

Handle magnets consciously. Their immense force can shock even professionals. Stay alert and respect their force.

Medical implants

People with a pacemaker should keep an large gap from magnets. The magnetic field can stop the operation of the life-saving device.

Nickel allergy

Allergy Notice: The nickel-copper-nickel coating contains nickel. If skin irritation appears, immediately stop handling magnets and wear gloves.

Do not drill into magnets

Dust generated during cutting of magnets is flammable. Do not drill into magnets unless you are an expert.

Magnets are brittle

Despite the nickel coating, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.

Caution!
