Shopping tips

This product is an exceptionally strong rod magnet, composed of modern NdFeB material, which, at dimensions of Ø10x10 mm, guarantees optimal power. This specific item features high dimensional repeatability and professional build quality, making it an excellent solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 5.53 kg), this product is available off-the-shelf from our European logistics center, ensuring rapid order fulfillment. Moreover, its Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.
It successfully proves itself in modeling, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the pull force of 54.23 N with a weight of only 5.89 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.
Due to the delicate structure of the ceramic sinter, you must not use force-fitting (so-called press-fit), as this risks chipping the coating of this professional component. To ensure stability in automation, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.
Magnets NdFeB grade N38 are suitable for the majority of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø10x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.
The presented product is a neodymium magnet with precisely defined parameters: diameter 10 mm and height 10 mm. The key parameter here is the holding force amounting to approximately 5.53 kg (force ~54.23 N), which, with such defined dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.
Standardly, the magnetic axis runs through the center of the cylinder, causing the greatest attraction force to occur on the bases with a diameter of 10 mm. 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 through the diameter if your project requires it.

Strengths as well as weaknesses of NdFeB magnets.

In addition to their long-term stability, neodymium magnets provide the following advantages:

  • They have unchanged lifting capacity, and over around 10 years their attraction force decreases symbolically – ~1% (according to theory),
  • They show high resistance to demagnetization induced by external magnetic fields,
  • The use of an refined layer of noble metals (nickel, gold, silver) causes the element to present itself better,
  • The surface of neodymium magnets generates a unique magnetic field – this is a distinguishing feature,
  • Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • Thanks to versatility in forming and the capacity to modify to individual projects,
  • Key role in electronics industry – they are utilized in mass storage devices, motor assemblies, advanced medical instruments, also other advanced devices.
  • Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

What to avoid - cons of neodymium magnets: application proposals

  • Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a strong case, which not only protects them against impacts but also raises their durability
  • When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
  • Limited possibility of making threads in the magnet and complicated shapes - recommended is cover - mounting mechanism.
  • Health risk resulting from small fragments of magnets can be dangerous, if swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these devices are able to be problematic in diagnostics medical when they are in the body.
  • High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities

Maximum lifting force for a neodymium magnet – what contributes to it?

The declared magnet strength refers to the limit force, obtained under laboratory conditions, namely:

  • with the application of a yoke made of special test steel, ensuring maximum field concentration
  • with a cross-section no less than 10 mm
  • characterized by even structure
  • with direct contact (no impurities)
  • during detachment in a direction vertical to the mounting surface
  • in temp. approx. 20°C

Practical lifting capacity: influencing factors

Bear in mind that the application force will differ depending on elements below, starting with the most relevant:

  • Gap (betwixt the magnet and the plate), since even a very small clearance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to varnish, rust or dirt).
  • Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of nominal force).
  • Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
  • Material composition – different alloys attracts identically. Alloy additives weaken the attraction effect.
  • Base smoothness – the more even the plate, the better the adhesion and stronger the hold. Roughness creates an air distance.
  • Thermal factor – high temperature weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.

* Lifting capacity testing was performed on a smooth plate of optimal thickness, under a perpendicular pulling force, however under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a small distance {between} the magnet and the plate lowers the holding force.

Safe handling of NdFeB magnets

Magnetic media

Do not bring magnets near a wallet, computer, or TV. The magnetism can permanently damage these devices and erase data from cards.

Handling rules

Handle with care. Neodymium magnets act from a long distance and snap with massive power, often quicker than you can move away.

Flammability

Mechanical processing of NdFeB material poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

This is not a toy

Product intended for adults. Tiny parts pose a choking risk, leading to intestinal necrosis. Keep away from kids and pets.

Medical interference

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

Sensitization to coating

It is widely known that nickel (standard magnet coating) is a common allergen. If you have an allergy, refrain from direct skin contact or choose coated magnets.

Crushing force

Pinching hazard: The attraction force is so great that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.

Protective goggles

Protect your eyes. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.

Keep away from electronics

Note: neodymium magnets generate a field that disrupts sensitive sensors. Maintain a separation from your mobile, tablet, and GPS.

Thermal limits

Regular neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. The loss of strength is permanent.
