Pulling power weakens sharply with every mm of gap. Keep in mind that even the smallest gap (e.g., dirt, varnish, rust) significantly diminishes the holding power. Neodymiums operate strongest at the point of direct contact; air break weakens the force. Analyze how rapidly the pull force fall, when the magnet does not adhere tightly to the metal substrate. When calculating the arrangement, discard redundant distances.

The following data shows the approximate shear load sufficient to cause the slippage of the magnet downwards along a vertical metal surface (considering typical friction coefficient). This parameter is a function of the air gap between the magnet and the surface.

Table 3: Vertical assembly (sliding) - vertical pull
MW 55x25 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	27.68 kg / 61.01 lbs 27675.0 g / 271.5 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	18.45 kg / 40.68 lbs 18450.0 g / 181.0 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	9.23 kg / 20.34 lbs 9225.0 g / 90.5 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	46.13 kg / 101.69 lbs 46125.0 g / 452.5 N

When hanging a holder on a upright surface (e.g., a board), it will only hold barely approx. 1/5 of nominal attraction strength. Gravity and a low friction coefficient influence the fact that magnets slide down faster than they pop off the substrate. Planning a vertical fastening? Note that the sliding force is much weaker than the maximum static pull force. On a painted metal, the magnet will give way down under a much lighter weight. Using a rubber layer can effectively raise the stability.

12 mm	100%	92.25 kg / 203.38 lbs 92250.0 g / 905.0 N

A thin metal plate is unable to absorb the entire magnetic field, which wastes potential of the magnet. Should you attach a powerful product to a thin surface, the magnetism will penetrate right through and the pull force will drop sharply. To utilize 100% of this magnet's potential, you need a suitably thick piece of metal. The saturation effect causes that on sheet metal structures (e.g., appliance housings), the magnet shows lower pull force. We recommend selecting the steel cross-section based on the following data.

Table 5: Thermal stability (material behavior) - power drop

Ordinary NdFeB products change their properties power past the thermal threshold. Avoid high temperatures – heat can irreversibly destroy this magnet. As the temperature rises, the neodymium's power temporarily decreases. Do not use this magnet in hot environments higher than its safe range. Too high temperature will cause irreversible degradation of magnetism.

*Engineering note: Thermal stability depends not only on the material grade, and the Permeance Coefficient Pc. Thin magnets (low permeance coefficient) are more susceptible to demagnetization sooner compared to rod magnets. The danger warning in the table points to a risk of irreversible loss for this specific geometry.

Two strong neodymiums attract each other from a significantly greater distance than a magnet and sheet combination. Such a system of magnet-to-magnet generates a stronger field and a further horizon of performance. Want to build a strong closure? Utilize two neodymiums instead of a neodymium and a steel. Remember that when attracting two neodymiums, the pinch force is extreme. The levitation is a bit weaker than the connection force, but still large.
*Flux density for N-N configuration drops to ~0 Gs at the geometric center of the gap (due to field cancellation).
Note: Figures apply to shear force of two identical magnets (friction ~0.15 for Ni-Ni coating).

Table 7: Hazards (implants) - precautionary measures
MW 55x25 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	27.5 cm
Hearing aid	10 Gs (1.0 mT)	21.5 cm
Timepiece	20 Gs (2.0 mT)	17.0 cm
Phone / Smartphone	40 Gs (4.0 mT)	13.0 cm
Remote	50 Gs (5.0 mT)	12.0 cm
Payment card	400 Gs (40.0 mT)	5.0 cm
HDD hard drive	600 Gs (60.0 mT)	4.5 cm

Extremely neodym field is a large risk to IT equipment as well as pacemakers. These NdFeB products produce a flux that disrupts operation of digital equipment. Remember: the unseen radiation passes through tissues and plastic. Exceptional care must be exercised by people with cochlear implants and insulin pumps. Also at risk are: mechanical watches, remotes, membranes, and displays. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Table 8: Impact energy (kinetic energy) - collision effects
MW 55x25 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	18.05 km/h (5.01 m/s)	5.60 J
30 mm	25.98 km/h (7.22 m/s)	11.60 J
50 mm	32.63 km/h (9.06 m/s)	18.30 J
100 mm	45.90 km/h (12.75 m/s)	36.21 J

NdFeB products are very brittle – a strong collision with metal risks their cracking. Control the attraction moment – a magnet released freely speeds with massive force. Impact energy can destroy the magnet or dangerous crushing to fingers. Always hold the magnet during mounting so it doesn't hit with great force against the steel surface. A collision at high speed almost guarantees destruction of the neodymium. Use safety goggles when playing with large magnets.

Environment	Effective steel pull	Effect
Air (land)	92.25 kg	Standard
Water (riverbed)	105.63 kg (+13.38 kg buoyancy gain)	+14.5%

Warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

Water displaces steel, making heavy objects slightly lighter. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Sliding resistance

*Caution: On a vertical surface, the magnet holds just approx. 20-30% of its max power.

2. Plate thickness effect

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

3. Heat tolerance

*For standard magnets, the max working temp 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 incredibly powerful rod magnet, produced from advanced NdFeB material, which, at dimensions of Ø55x25 mm, guarantees the highest energy density. This specific item features high dimensional repeatability and industrial build quality, making it a perfect solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 92.25 kg), this product is in stock from our European logistics center, ensuring lightning-fast order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

This model is ideal for building generators, advanced sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the high power of 904.94 N with a weight of only 445.47 g, this rod is indispensable in miniature devices 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 precision component. To ensure long-term durability in industry, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Magnets NdFeB grade N38 are suitable for the majority of applications in automation and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø55x25), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

This model is characterized by dimensions Ø55x25 mm, which, at a weight of 445.47 g, makes it an element with high magnetic energy density. The value of 904.94 N means that the magnet is capable of holding a weight many times exceeding its own mass of 445.47 g. The product has a [NiCuNi] coating, which secures it against external factors, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 25 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 diametrically if your project requires it.

Pros and cons of Nd₂Fe₁₄B magnets.

Pros

In addition to their magnetic efficiency, neodymium magnets provide the following advantages:

They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
Neodymium magnets are characterized by remarkably resistant to loss of magnetic properties caused by external field sources,
A magnet with a shiny nickel surface has better aesthetics,
The surface of neodymium magnets generates a powerful magnetic field – this is a key feature,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
Possibility of exact forming and optimizing to complex requirements,
Fundamental importance in high-tech industry – they are used in computer drives, electric motors, advanced medical instruments, and complex engineering applications.
Thanks to concentrated force, small magnets offer high operating force, in miniature format,

Disadvantages

Drawbacks and weaknesses of neodymium magnets and ways of using them

Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a strong case, which not only protects them against impacts but also increases their durability
Neodymium magnets decrease 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
Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in creating nuts and complex shapes in magnets, we recommend using a housing - magnetic mechanism.
Health risk related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. Additionally, tiny parts of these devices can be problematic in diagnostics medical when they are in the body.
Due to expensive raw materials, their price is relatively high,

Lifting parameters

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

Breakaway force was determined for ideal contact conditions, assuming:

on a block made of mild steel, optimally conducting the magnetic flux
possessing a massiveness of minimum 10 mm to avoid saturation
with an polished contact surface
under conditions of gap-free contact (surface-to-surface)
for force applied at a right angle (in the magnet axis)
in neutral thermal conditions

Lifting capacity in real conditions – factors

Effective lifting capacity is influenced by specific conditions, mainly (from priority):

Distance – the presence of any layer (rust, tape, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
Material type – ideal substrate is pure iron steel. Hardened steels may attract less.
Plate texture – smooth surfaces ensure maximum contact, which improves force. Uneven metal weaken the grip.
Temperature – temperature increase causes a temporary drop of induction. Check the maximum operating temperature for a given model.

Lifting capacity was measured with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate reduces the holding force.

Warnings

Combustion hazard

Fire hazard: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this may cause fire.

Magnetic media

Powerful magnetic fields can erase data on payment cards, HDDs, and storage devices. Keep a distance of at least 10 cm.

Implant safety

For implant holders: Powerful magnets affect medical devices. Keep minimum 30 cm distance or ask another person to handle the magnets.

Do not overheat magnets

Do not overheat. NdFeB magnets are susceptible to heat. If you require resistance above 80°C, inquire about HT versions (H, SH, UH).

Handling rules

Handle magnets consciously. Their powerful strength can surprise even professionals. Stay alert and respect their power.

GPS Danger

Note: neodymium magnets produce a field that interferes with precision electronics. Maintain a separation from your mobile, device, and navigation systems.

Shattering risk

Despite metallic appearance, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.

Pinching danger

Protect your hands. Two large magnets will snap together instantly with a force of massive weight, destroying anything in their path. Exercise extreme caution!

This is not a toy

Strictly keep magnets away from children. Ingestion danger is significant, and the effects of magnets connecting inside the body are tragic.

Skin irritation risks

Some people experience a hypersensitivity to Ni, which is the common plating for NdFeB magnets. Extended handling may cause dermatitis. We recommend wear safety gloves.
