Pulling power weakens sharply with every subsequent millimeter of distance. Keep in mind that every additional insulation layer (e.g., dirt, paint, rust) noticeably weakens the grip. Neodymiums work optimally in perfect adhesion; air break weakens the force. Analyze how rapidly the load capacity plummet, when the product does not touch flatly to the steel surface. When designing the mounting, eliminate unnecessary gaps.

This section defines the theoretical holding capacity necessary to initiate the slippage of the magnet downwards on a vertical steel wall (considering typical friction coefficient). This value is relative to the separation distance between the magnet and the surface.

Table 3: Vertical assembly (shearing) - vertical pull

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

When hanging a element on a vertical wall (e.g., a fridge), it will only hold just about 20%-30% of nominal attraction strength. Gravity as well as a low friction coefficient influence the fact that holders slip faster than they pull off. Want to create a hanger? Consider that the sliding force is significantly lower than the maximum static pull force. On a slippery surface, the holder will give way down under a significantly smaller weight. Application of an anti-slip pad can drastically improve the result.

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

A thin metal plate cannot take in the entire magnetic field, which weakens actual performance of the holder. If you mount a strong magnet to a too thin substrate, the magnetism will penetrate right through and the attraction force will be weaker. To utilize the maximum of this magnet's power, you require a sufficiently solid backing of metal. The saturation effect causes that on delicate walls (e.g., appliance housings), the holder works worse. We advise picking the steel dimension according to the table below.

Ordinary NdFeB products lose strength after exceeding the maximum temperature. Watch out for overheating – excessive heat can permanently demagnetize this product. As the temperature rises, the magnet's power momentarily drops. Avoid using this product close to ovens higher than its safe range. Exceeding the critical threshold will result in irreversible degradation of magnetic properties.

*Engineering note: Thermal stability depends not only on the material grade, as well as the dimension ratios. Low-profile magnets (low Pc) risk losing magnetic properties under lower heat stress than taller cylinders. Red status in the table points to a risk of irreversible loss for this particular item.

Two magnets interact from a wider radius than a magnet and sheet setup. The setup of two magnets creates a more powerful interaction and a wider radius of performance. Designing a powerful holder? Utilize two neodymiums instead of a neodymium and a striker plate. Remember that when attracting two neodymiums, the pinch force is massive. The levitation is slightly lower than the connection force, but still large.
*Flux density for N-N configuration reaches ~0 Gs in the exact middle of the gap (resulting from vector opposition).
Important: Results show shear force of a pair of same neodymium magnets (friction ~0.15 for Ni-Ni layer).

A strong magnetic field poses a large risk to electronic devices as well as medical implants. These neodymiums generate a flux that prevents correct functioning of sensitive medical devices. Remember: the unseen radiation penetrates the body and glass. Exceptional care must be exercised by people with cochlear implants and insulin pumps. The risk also applies to: automatic timepieces, car keys, membranes, and screens. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

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

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	19.19 km/h (5.33 m/s)	6.33 J
30 mm	23.74 km/h (6.59 m/s)	9.68 J
50 mm	24.27 km/h (6.74 m/s)	10.12 J
100 mm	24.39 km/h (6.78 m/s)	10.23 J

Magnetic elements are very brittle – a collision with steel causes immediate chipping. Control the attraction moment – a neodymium left loose becomes dangerous. Impact energy can cause material chips or injury to fingers. Always hold the magnet during bringing near metal so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Wear eye protection when playing with large magnets.

Warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

Contrary to myths, water does not block the magnetic field. Buoyancy helps in lifting finds.

1. Vertical hold

*Caution: On a vertical wall, the magnet retains merely approx. 20-30% of its nominal pull.

2. Steel thickness impact

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

3. Heat tolerance

*For N38 grade, the safety 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 offered product is an extremely powerful cylindrical magnet, produced from durable NdFeB material, which, with dimensions of Ø55x25 mm, guarantees the highest energy density. This specific item is characterized by high dimensional repeatability and professional build quality, making it a perfect solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 92.25 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring rapid order fulfillment. Furthermore, its Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

It finds application in modeling, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 904.94 N with a weight of only 445.47 g, this rod is indispensable in electronics and wherever low weight is crucial.

Since our magnets have a very precise dimensions, the best method is to glue them into holes with a slightly larger diameter (e.g., 55.1 mm) using epoxy glues. To ensure stability in automation, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Magnets N38 are strong enough for the majority of applications in automation and machine building, where extreme miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø55x25), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale 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 key parameter here is the lifting capacity amounting to approximately 92.25 kg (force ~904.94 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.

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 through the diameter if your project requires it.

Advantages as well as disadvantages of Nd₂Fe₁₄B magnets.

Advantages

Besides their exceptional strength, neodymium magnets offer the following advantages:

Their magnetic field is durable, and after around ten years it decreases only by ~1% (according to research),
They maintain their magnetic properties even under external field action,
In other words, due to the shiny finish of nickel, the element gains visual value,
Magnets are characterized by maximum magnetic induction on the outer side,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
Thanks to flexibility in constructing and the ability to customize to specific needs,
Significant place in high-tech industry – they are commonly used in computer drives, motor assemblies, advanced medical instruments, and technologically advanced constructions.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which allows their use in compact constructions

Weaknesses

Disadvantages of neodymium magnets:

They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
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 stability even at temperatures up to 230°C
They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
We suggest cover - magnetic mechanism, due to difficulties in producing threads inside the magnet and complicated shapes.
Health risk resulting from small fragments of magnets are risky, if swallowed, which becomes key in the context of child safety. It is also worth noting that small elements of these devices are able to complicate diagnosis medical after entering the body.
Due to neodymium price, their price is higher than average,

Lifting parameters

Optimal lifting capacity of a neodymium magnet – what contributes to it?

Information about lifting capacity is the result of a measurement for optimal configuration, assuming:

on a block made of structural steel, effectively closing the magnetic field
whose transverse dimension reaches at least 10 mm
with a surface cleaned and smooth
without the slightest clearance between the magnet and steel
under axial force direction (90-degree angle)
at standard ambient temperature

Lifting capacity in real conditions – factors

Real force impacted by specific conditions, such as (from priority):

Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of nominal force).
Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
Metal type – different alloys reacts the same. Alloy additives worsen the attraction effect.
Surface condition – ground elements guarantee perfect abutment, which increases force. Rough surfaces reduce efficiency.
Temperature – temperature increase results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.

Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the load capacity is reduced by as much as fivefold. In addition, even a minimal clearance between the magnet and the plate lowers the holding force.

Precautions when working with neodymium magnets

Maximum temperature

Avoid heat. NdFeB magnets are sensitive to temperature. If you require resistance above 80°C, look for special high-temperature series (H, SH, UH).

Compass and GPS

A strong magnetic field negatively affects the functioning of compasses in phones and GPS navigation. Maintain magnets close to a device to avoid breaking the sensors.

Dust is flammable

Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this may cause fire.

Warning for allergy sufferers

Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness occurs, immediately stop handling magnets and wear gloves.

Handling guide

Handle magnets consciously. Their immense force can surprise even professionals. Stay alert and do not underestimate their power.

Safe distance

Intense magnetic fields can corrupt files on credit cards, hard drives, and storage devices. Stay away of at least 10 cm.

Health Danger

Life threat: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.

Product not for children

These products are not toys. Eating a few magnets may result in them attracting across intestines, which poses a direct threat to life and requires urgent medical intervention.

Pinching danger

Protect your hands. Two powerful magnets will join instantly with a force of massive weight, destroying everything in their path. Exercise extreme caution!

Shattering risk

Beware of splinters. Magnets can explode upon violent connection, launching shards into the air. Wear goggles.
