Pulling power weakens sharply with every mm of spacing. Keep in mind that even the smallest gap (e.g., contamination, varnish, veneer) noticeably weakens the grip. Magnets work optimally in perfect adhesion; air break kills the force. Analyze how quickly the parameters fall, when the product does not adhere directly to the metal substrate. When calculating the assembly, avoid redundant distances.

This section presents the estimated weight limit sufficient to cause the slippage of the magnet downwards on a upright steel wall (assuming standard friction coefficient). This value varies with the separation distance between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull

When mounting a magnet on a upright wall (e.g., a board), it will only hold only about 1/5 of nominal attraction strength. Gravity as well as a low friction coefficient cause that products move down easier than they pop off the substrate. Want to create a vertical fastening? Consider that the sliding force is noticeably lower than the maximum static pull force. On a slippery surface, the magnet will slip down under a significantly smaller cargo. Using a rubber layer can effectively improve the result.

A thin metal plate cannot take in the entire magnetic field, which wastes potential of the magnet. If you mount a strong magnet to a thin surface, the magnetism will penetrate right through and the pull force will drop sharply. To utilize the maximum of this neodymium's potential, you require a sufficiently solid element of metal. The material oversaturation means that on delicate walls (e.g., appliance housings), the magnet shows lower pull force. We advise picking the steel thickness based on the following data.

Classic neodymiums change their properties power after exceeding the maximum temperature. Protect against heat – excessive heat can permanently destroy this product. With increasing heat, the magnet's force briefly drops. Do not use this magnet close to ovens exceeding its operating temperature limit. Exceeding the critical threshold will lead to permanent loss of magnetic properties.

*Technical advisory: Thermal stability depends not only on the material grade, and the Permeance Coefficient Pc. Flat magnets (low permeance coefficient) are more susceptible to demagnetization under lower heat stress than taller cylinders. Warning indicator in the table signals permanent field degradation for this particular item.

Two strong neodymiums attract each other from a much further distance than a neodymium and metal combination. Such a system of magnet-to-magnet generates a stronger field and a further horizon of performance. Want to build a powerful holder? Utilize two neodymiums instead of a neodymium and a striker plate. Be careful that when attracting two neodymiums, the impact force is extreme. The repulsion force is marginally weaker than the connection force, but still large.
*The magnetic induction between like poles reaches ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
Note: Estimates show sliding force of two matching neodymium magnets (friction ~0.15 for Ni-Ni coating).

A strong magnetic field poses a serious hazard to electronics as well as pacemakers. These NdFeB products produce a flux that destroys function of sensitive medical devices. Be aware: the invisible magnetic field penetrates the body and plastic. Exceptional care must be exercised by people with hearing aids and drug dispensers. The risk also applies to: mechanical watches, car keys, membranes, and displays. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Table 8: Collisions (kinetic energy) - warning

100 mm	72.63 km/h (20.17 m/s)	5.75 J

Magnetic elements are prone to chipping – a strong collision with metal risks their cracking. Watch the impact speed – a neodymium left loose speeds with massive force. Kinetic force can cause material chips or dangerous crushing to fingers. Always hold the magnet during mounting so it doesn't slam with momentum against the metal. A collision at high speed ends with a crack of the neodymium. Use safety goggles when playing with powerful specimens.

Corrosion warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

Contrary to myths, water does not block the magnetic field. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Vertical hold

*Note: On a vertical wall, the magnet holds merely ~20% of its nominal pull.

2. Plate thickness effect

*Thin steel (e.g. 0.5mm PC case) severely reduces the holding force.

3. Power loss vs temp

*For N38 grade, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.55

The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. 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 P_c (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 P_c 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 an exceptionally strong cylinder magnet, made from durable NdFeB material, which, at dimensions of Ø21.9x10 mm, guarantees the highest energy density. This specific item is characterized by an accuracy of ±0.1mm and professional build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with significant force (approx. 14.65 kg), this product is in stock from our warehouse in Poland, ensuring lightning-fast order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is perfect for building generators, advanced sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the high power of 143.71 N with a weight of only 28.25 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.

Since our magnets have a very precise dimensions, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 21.9.1 mm) using epoxy glues. To ensure stability 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 industrial neodymium magnets, offering a great economic balance and operational stability. If you need the strongest magnets in the same volume (Ø21.9x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 21.9 mm and height 10 mm. The key parameter here is the lifting capacity amounting to approximately 14.65 kg (force ~143.71 N), which, with such compact dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface 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 21.9 mm. Such an arrangement is standard 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 diametrically if your project requires it.

Advantages as well as disadvantages of Nd₂Fe₁₄B magnets.

Benefits

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

They do not lose magnetism, even during approximately 10 years – the drop in strength is only ~1% (theoretically),
Magnets effectively protect themselves against loss of magnetization caused by external fields,
By applying a lustrous coating of nickel, the element presents an elegant look,
They show high magnetic induction at the operating surface, which affects their effectiveness,
Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures approaching 230°C and above...
Possibility of custom shaping as well as adjusting to atypical needs,
Huge importance in innovative solutions – they find application in data components, brushless drives, medical equipment, also modern systems.
Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Weaknesses

Cons of neodymium magnets: application proposals

They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
We suggest cover - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complex forms.
Health risk to health – tiny shards of magnets are risky, if swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, tiny parts of these devices can be problematic in diagnostics medical when they are in the body.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities

Holding force characteristics

Maximum lifting capacity of the magnet – what affects it?

Information about lifting capacity was determined for ideal contact conditions, assuming:

on a block made of mild steel, optimally conducting the magnetic field
possessing a thickness of min. 10 mm to ensure full flux closure
with an polished contact surface
under conditions of gap-free contact (surface-to-surface)
for force applied at a right angle (pull-off, not shear)
at temperature room level

Determinants of practical lifting force of a magnet

Please note that the application force will differ influenced by the following factors, in order of importance:

Gap (between the magnet and the plate), because even a very small distance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to varnish, corrosion or debris).
Loading method – catalog parameter refers to pulling vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of maximum force).
Base massiveness – too thin sheet does not close the flux, causing part of the flux to be lost into the air.
Material type – ideal substrate is pure iron steel. Cast iron may have worse magnetic properties.
Surface finish – full contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
Thermal environment – temperature increase causes a temporary drop of force. Check the thermal limit for a given model.

Lifting capacity was determined by applying a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under shearing force the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.

Precautions when working with NdFeB magnets

Danger to pacemakers

For implant holders: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or request help to work with the magnets.

Magnet fragility

Despite metallic appearance, the material is delicate and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.

Magnetic media

Avoid bringing magnets close to a wallet, computer, or screen. The magnetic field can destroy these devices and erase data from cards.

Maximum temperature

Standard neodymium magnets (N-type) lose power when the temperature exceeds 80°C. Damage is permanent.

Do not underestimate power

Before starting, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.

Nickel coating and allergies

A percentage of the population suffer from a sensitization to nickel, which is the typical protective layer for NdFeB magnets. Prolonged contact may cause a rash. We suggest use protective gloves.

Keep away from children

NdFeB magnets are not suitable for play. Eating several magnets can lead to them pinching intestinal walls, which poses a severe health hazard and requires immediate surgery.

Machining danger

Powder created during grinding of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.

Serious injuries

Large magnets can smash fingers in a fraction of a second. Never put your hand between two strong magnets.
