1. Vertical hold

*Note: On a vertical surface, the magnet retains only a fraction of its perpendicular strength.

2. Steel thickness impact

*Thin steel (e.g. computer case) severely limits the holding force.

3. Power loss vs temp

*For N38 grade, the max working temp is 80°C.

4. Demagnetization curve and operating point (B-H)

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.89

This simulation demonstrates the magnetic stability of the selected magnet under specific geometric conditions. The solid red line represents the demagnetization curve (material potential), while the dashed blue line is the load line based on the magnet's geometry. The Pc (Permeance Coefficient), also known as the load line slope, is a dimensionless value that describes the relationship between the magnet's shape and its magnetic stability. The intersection of these two lines (the black dot) is the operating point — it determines the actual magnetic flux density generated by the magnet in this specific configuration. A higher Pc value means the magnet is more 'slender' (tall relative to its area), resulting in a higher operating point and better resistance to irreversible demagnetization caused by external fields or temperature. A value of 0.42 is relatively low (typical for flat magnets), meaning the operating point is closer to the 'knee' of the curve — caution is advised when operating at temperatures near the maximum limit to avoid strength loss.

The presented product is a very strong cylindrical magnet, produced from advanced NdFeB material, which, with dimensions of Ø6x6 mm, guarantees the highest energy density. The MW 6x6 / N38 model is characterized by high dimensional repeatability and professional build quality, making it an ideal solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 1.14 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Furthermore, its Ni-Cu-Ni coating effectively protects it against corrosion in typical 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 high power of 11.18 N with a weight of only 1.27 g, this rod is indispensable in miniature devices and wherever low weight is crucial.
Due to the brittleness of the NdFeB material, we absolutely advise against force-fitting (so-called press-fit), as this risks immediate cracking of this professional component. To ensure stability in automation, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.
Grade N38 is the most frequently chosen standard for professional neodymium magnets, offering a great economic balance and operational stability. 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 available off-the-shelf 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 holding force amounting to approximately 1.14 kg (force ~11.18 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.
This cylinder is magnetized axially (along the height of 6 mm), which means that the N and S poles are located on the flat, circular surfaces. Such an arrangement is most desirable when connecting magnets in stacks (e.g., in filters) or when mounting in sockets at the bottom of a hole. On request, we can also produce versions magnetized through the diameter if your project requires it.

Pros and cons of rare earth magnets.

Strengths

Besides their high retention, neodymium magnets are valued for these benefits:
  • They retain magnetic properties for nearly ten years – the drop is just ~1% (based on simulations),
  • They do not lose their magnetic properties even under close interference source,
  • Thanks to the shimmering finish, the surface of Ni-Cu-Ni, gold, or silver gives an visually attractive appearance,
  • Magnets are distinguished by maximum magnetic induction on the working surface,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
  • Thanks to freedom in forming and the ability to customize to individual projects,
  • Universal use in high-tech industry – they are used in HDD drives, drive modules, diagnostic systems, and modern systems.
  • Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which allows their use in miniature devices

Limitations

What to avoid - cons of neodymium magnets: application proposals
  • Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a special holder, which not only secures them against impacts but also raises their durability
  • When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
  • Due to limitations in realizing nuts and complex forms in magnets, we recommend using a housing - magnetic mount.
  • Health risk related to microscopic parts of magnets pose a threat, in case of ingestion, which becomes key in the aspect of protecting the youngest. Additionally, small components of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
  • Due to complex production process, their price exceeds standard values,

Pull force analysis

Maximum lifting force for a neodymium magnet – what affects it?

The load parameter shown concerns the peak performance, measured under laboratory conditions, namely:
  • with the use of a yoke made of special test steel, ensuring full magnetic saturation
  • with a cross-section no less than 10 mm
  • with a surface perfectly flat
  • without any clearance between the magnet and steel
  • under vertical force direction (90-degree angle)
  • in temp. approx. 20°C

Lifting capacity in real conditions – factors

In real-world applications, the real power results from many variables, presented from most significant:
  • Air gap (between the magnet and the metal), because even a microscopic clearance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
  • Load vector – highest force is available only during pulling at a 90° angle. The shear force of the magnet along the plate is typically many times smaller (approx. 1/5 of the lifting capacity).
  • Plate thickness – insufficiently thick steel causes magnetic saturation, causing part of the power to be wasted to the other side.
  • Steel type – low-carbon steel attracts best. Alloy admixtures reduce magnetic permeability and lifting capacity.
  • Surface structure – the more even the plate, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
  • Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity was assessed with the use of a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.

Safe handling of NdFeB magnets
Handling guide

Exercise caution. Rare earth magnets attract from a long distance and snap with huge force, often quicker than you can move away.

Combustion hazard

Powder produced during machining of magnets is self-igniting. Do not drill into magnets unless you are an expert.

Safe distance

Do not bring magnets close to a purse, computer, or TV. The magnetic field can destroy these devices and wipe information from cards.

This is not a toy

NdFeB magnets are not intended for children. Eating a few magnets can lead to them connecting inside the digestive tract, which constitutes a direct threat to life and necessitates immediate surgery.

Phone sensors

A strong magnetic field interferes with the operation of compasses in smartphones and navigation systems. Maintain magnets close to a smartphone to avoid breaking the sensors.

Nickel allergy

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

Medical interference

People with a pacemaker must keep an large gap from magnets. The magnetic field can interfere with the operation of the implant.

Heat warning

Regular neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. Damage is permanent.

Eye protection

NdFeB magnets are ceramic materials, meaning they are fragile like glass. Clashing of two magnets leads to them breaking into shards.

Crushing risk

Mind your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
