This product is an extremely powerful cylindrical magnet, composed of durable NdFeB material, which, at dimensions of Ø6x6 mm, guarantees maximum efficiency. This specific item features high dimensional repeatability and industrial build quality, making it a perfect solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 1.14 kg), this product is in stock from our warehouse in Poland, ensuring rapid order fulfillment. Furthermore, its Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.
It successfully proves itself in modeling, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the pull force of 11.18 N with a weight of only 1.27 g, this rod is indispensable in electronics and wherever low weight is crucial.
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 precision component. To ensure stability in industry, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.
Magnets N38 are suitable for 90% 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 (Ø6x6), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.
The presented product is a neodymium magnet with precisely defined parameters: diameter 6 mm and height 6 mm. The key parameter here is the lifting capacity amounting to approximately 1.14 kg (force ~11.18 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.
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 6 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 diametrically if your project requires it.

Advantages as well as disadvantages of neodymium magnets.

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

  • They do not lose magnetism, even after approximately 10 years – the decrease in lifting capacity is only ~1% (according to tests),
  • They show high resistance to demagnetization induced by external disturbances,
  • The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
  • They are known for high magnetic induction at the operating surface, which increases their power,
  • Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
  • Thanks to freedom in shaping and the capacity to adapt to specific needs,
  • Fundamental importance in advanced technology sectors – they serve a role in mass storage devices, motor assemblies, precision medical tools, also multitasking production systems.
  • Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in small systems

Disadvantages of neodymium magnets:

  • Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a special holder, which not only secures them against impacts but also raises their durability
  • Neodymium magnets decrease their force 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
  • They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
  • Limited ability of creating threads in the magnet and complex shapes - preferred is a housing - magnet mounting.
  • Health risk related to microscopic parts of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small elements of these magnets can complicate diagnosis medical after entering the body.
  • High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Maximum lifting capacity of the magnetwhat it depends on?

Holding force of 1.14 kg is a theoretical maximum value conducted under the following configuration:

  • on a block made of mild steel, optimally conducting the magnetic field
  • with a thickness minimum 10 mm
  • characterized by lack of roughness
  • without any insulating layer between the magnet and steel
  • for force acting at a right angle (pull-off, not shear)
  • at temperature room level

Determinants of lifting force in real conditions

Bear in mind that the working load may be lower subject to elements below, starting with the most relevant:

  • Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
  • Angle of force application – maximum parameter is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the plate is standardly several times lower (approx. 1/5 of the lifting capacity).
  • Plate thickness – insufficiently thick steel does not accept the full field, causing part of the power to be lost into the air.
  • Steel grade – ideal substrate is pure iron steel. Hardened steels may have worse magnetic properties.
  • Surface condition – smooth surfaces ensure maximum contact, which increases 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 testing was performed on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the lifting capacity is smaller. In addition, even a slight gap {between} the magnet and the plate decreases the load capacity.

H&S for magnets

Warning for allergy sufferers

It is widely known that the nickel plating (standard magnet coating) is a common allergen. If your skin reacts to metals, refrain from touching magnets with bare hands and select versions in plastic housing.

No play value

Absolutely store magnets away from children. Choking hazard is significant, and the effects of magnets connecting inside the body are life-threatening.

Permanent damage

Avoid heat. Neodymium magnets are sensitive to heat. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).

Beware of splinters

Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.

Protect data

Data protection: Neodymium magnets can ruin data carriers and delicate electronics (heart implants, medical aids, timepieces).

Do not underestimate power

Be careful. Rare earth magnets act from a long distance and connect with huge force, often quicker than you can react.

Danger to pacemakers

People with a pacemaker should keep an absolute distance from magnets. The magnetism can disrupt the functioning of the life-saving device.

Crushing force

Mind your fingers. Two powerful magnets will snap together instantly with a force of massive weight, crushing everything in their path. Exercise extreme caution!

Combustion hazard

Powder generated during cutting of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.

GPS Danger

An intense magnetic field interferes with the functioning of compasses in smartphones and navigation systems. Do not bring magnets near a device to avoid damaging the sensors.

Danger!
