Frequently asked questions

What is the maximum working temperature of a disc magnet?
Standard N-series grades work up to 80 °C. Grades N50, N52 and N54 have a lower limit of 60 °C, because coercivity falls as BHmax rises. Higher temperatures require the H (120 °C), SH (150 °C), UH (180 °C), EH (200 °C) or AH (230 °C) series. Within the working range the magnet loses about 0.11% of its induction per degree, and that loss is reversible.
What is the difference between N38, N42 and N52?
The number after N is the energy product BHmax. Moving from N38 to N52 raises it by several tens of percent, but the real holding force increases by roughly 20%, because force also depends on geometry and on the magnetic circuit. N52 costs about twice as much as N42, so for most mounting work N38–N42 is the best price-to-force ratio.
What is the dimensional tolerance?
±0.1 mm as standard, ±0.05 mm to order. The tolerance is stated next to the dimensions on every product page.

1. Wall mount (shear)

*Caution: On a vertical surface, the magnet retains merely ~20% of its max power.

2. Steel saturation

*Thin metal sheet (e.g. computer case) significantly limits the holding force.

3. Heat tolerance

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

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 1.21

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.

Magnetic Induction

Other offers

The presented product is a very strong cylindrical magnet, made from durable NdFeB material, which, at dimensions of Ø5x10 mm, guarantees optimal power. This specific item features a tolerance of ±0.1mm and professional build quality, making it an excellent solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 0.56 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.
This model is perfect for building generators, advanced sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the pull force of 5.45 N with a weight of only 1.47 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.
Since our magnets have a tolerance of ±0.1mm, the best method is to glue them into holes with a slightly larger diameter (e.g., 5.1 mm) using two-component epoxy glues. To ensure long-term durability in industry, anaerobic resins 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 popular standard for professional neodymium magnets, offering an optimal price-to-power ratio and high resistance to demagnetization. If you need even stronger magnets in the same volume (Ø5x10), 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 5 mm and height 10 mm. The value of 5.45 N means that the magnet is capable of holding a weight many times exceeding its own mass of 1.47 g. 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 10 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.

Advantages as well as disadvantages of Nd2Fe14B magnets.

Pros

Apart from their notable magnetism, neodymium magnets have these key benefits:
  • Their power is durable, and after around ten years it decreases only by ~1% (theoretically),
  • Neodymium magnets prove to be extremely resistant to loss of magnetic properties caused by external interference,
  • In other words, due to the metallic finish of gold, the element becomes visually attractive,
  • Magnetic induction on the working part of the magnet turns out to be extremely intense,
  • Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures approaching 230°C and above...
  • Thanks to versatility in constructing and the capacity to adapt to client solutions,
  • Universal use in future technologies – they serve a role in magnetic memories, brushless drives, medical equipment, and modern systems.
  • Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which enables their usage in miniature devices

Cons

What to avoid - cons of neodymium magnets and ways of using them
  • Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a strong case, which not only secures them against impacts but also raises their durability
  • Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. 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 suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
  • Limited ability of producing threads in the magnet and complicated shapes - recommended is a housing - mounting mechanism.
  • Possible danger to health – tiny shards of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that tiny parts of these magnets can be problematic in diagnostics medical when they are in the body.
  • Due to neodymium price, their price is higher than average,

Lifting parameters

Best holding force of the magnet in ideal parameterswhat contributes to it?

The specified lifting capacity refers to the peak performance, obtained under laboratory conditions, specifically:
  • on a base made of structural steel, perfectly concentrating the magnetic flux
  • with a cross-section minimum 10 mm
  • with an ground contact surface
  • with total lack of distance (without coatings)
  • for force acting at a right angle (in the magnet axis)
  • at ambient temperature approx. 20 degrees Celsius

Determinants of lifting force in real conditions

During everyday use, the actual lifting capacity is determined by many variables, listed from the most important:
  • Clearance – existence of any layer (paint, dirt, gap) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
  • Direction of force – maximum parameter is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is usually several times smaller (approx. 1/5 of the lifting capacity).
  • Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
  • Steel type – low-carbon steel attracts best. Higher carbon content reduce magnetic permeability and lifting capacity.
  • Surface structure – the more even the plate, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
  • Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity was measured by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, in contrast under shearing force the load capacity is reduced by as much as 5 times. Additionally, even a small distance between the magnet’s surface and the plate decreases the load capacity.

Precautions when working with NdFeB magnets
Dust is flammable

Fire hazard: Neodymium dust is highly flammable. Do not process magnets without safety gear as this risks ignition.

Heat warning

Monitor thermal conditions. Heating the magnet to high heat will permanently weaken its magnetic structure and pulling force.

Electronic hazard

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

Medical implants

Life threat: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.

Magnet fragility

Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.

Allergy Warning

Nickel alert: The nickel-copper-nickel coating contains nickel. If redness occurs, immediately stop working with magnets and use protective gear.

Hand protection

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

Magnetic interference

Note: neodymium magnets produce a field that interferes with sensitive sensors. Keep a separation from your mobile, device, and GPS.

Powerful field

Handle magnets consciously. Their immense force can shock even experienced users. Be vigilant and do not underestimate their power.

No play value

These products are not suitable for play. Swallowing multiple magnets can lead to them connecting inside the digestive tract, which constitutes a critical condition and requires urgent medical intervention.
