Pulling power drops sharply with every mm of gap. Note that even a microscopic distance (e.g., dirt, varnish, dust) significantly weakens the grip. Neodymiums hold strongest during direct contact; air break weakens the force. Analyze how quickly the parameters drop, when the product does not adhere directly to the metal substrate. When calculating the assembly, eliminate redundant distances.

50 mm	Stal (~0.2)	0.08 kg / 0.18 lbs 80.0 g / 0.8 N

This section presents the approximate force required to cause the sliding of the magnet down on a vertical metal surface (considering typical friction coefficient). This value depends on the air gap between the magnet and the metal.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces
MW 50x20 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	21.03 kg / 46.36 lbs 21030.0 g / 206.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	14.02 kg / 30.91 lbs 14020.0 g / 137.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	7.01 kg / 15.45 lbs 7010.0 g / 68.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	35.05 kg / 77.27 lbs 35050.0 g / 343.8 N

When placing a element on a vertical plane (e.g., a board), it will only hold just about 20%-30% of its maximum pull force. Gravity and a low friction coefficient cause that holders slip easier than they pull off. Planning a vertical fastening? Note that the shear force is significantly lower than the perpendicular breakaway force. On a smooth steel, the magnet will give way down under a much lighter cargo. Using a rubber pad can effectively raise the stability.

Table 4: Material efficiency (substrate influence) - power losses
MW 50x20 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	3%	2.34 kg / 5.15 lbs 2336.7 g / 22.9 N
1 mm	8%	5.84 kg / 12.88 lbs 5841.7 g / 57.3 N
2 mm	17%	11.68 kg / 25.76 lbs 11683.3 g / 114.6 N
3 mm	25%	17.53 kg / 38.64 lbs 17525.0 g / 171.9 N
5 mm	42%	29.21 kg / 64.39 lbs 29208.3 g / 286.5 N
10 mm	83%	58.42 kg / 128.79 lbs 58416.7 g / 573.1 N
11 mm	92%	64.26 kg / 141.67 lbs 64258.3 g / 630.4 N
12 mm	100%	70.10 kg / 154.54 lbs 70100.0 g / 687.7 N

A too thin steel is incapable of focus the full magnetic flux, which weakens actual performance of the holder. Should you install a neodymium to a too thin substrate, the magnetism will pass right through and the holding will be smaller. To achieve 100% of this magnet's potential, you require a sufficiently solid element of metal. The saturation effect means that on delicate walls (e.g., thin profiles), the product shows lower pull force. We advise picking the steel cross-section from these parameters.

100 °C	-28.8%	49.91 kg / 110.04 lbs 49911.2 g / 489.6 N

Ordinary NdFeB products lose power past the thermal threshold. Avoid high temperatures – excessive heat can permanently demagnetize this product. With every degree above norm, the neodymium's capacity temporarily decreases. Do not use this magnet close to ovens higher than its operating temperature limit. Exceeding the critical threshold will result in irreversible degradation of magnetic properties.

*Engineering note: Heat tolerance is determined by both grade, and the Permeance Coefficient Pc. Thin magnets (pancake types) may lose charge permanently under lower heat stress compared to rod magnets. Red status in the table signals permanent field degradation for this particular item.

Two strong neodymiums attract each other from a wider radius than a magnet and steel combination. The connection of two magnets generates a stronger field and a larger range of operation. Designing a powerful holder? Utilize two neodymiums instead of a neodymium and a steel. Remember that when attracting two neodymiums, the collision energy is massive. The levitation is slightly lower than the attraction, but still impressive.
*Flux density in repulsion mode is approximately ~0 Gs at the midpoint between the magnets (due to field cancellation).
Note: Figures show friction force of two identical magnets (friction coefficient ~0.15 for Ni-Ni layer).

Table 7: Hazards (electronics) - precautionary measures

Powerful magnet radiation is a large risk to electronic devices as well as medical implants. These magnets generate a flux that disrupts operation of sensitive medical devices. Be aware: the invisible magnetic field penetrates the body and housings. Special caution must be exercised by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, remotes, speakers, and screens. Do not place the magnet near cards, HDD media, or precise measuring instruments.

Table 8: Collisions (kinetic energy) - warning
MW 50x20 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	19.09 km/h (5.30 m/s)	4.14 J
30 mm	27.63 km/h (7.67 m/s)	8.67 J
50 mm	34.92 km/h (9.70 m/s)	13.85 J
100 mm	49.21 km/h (13.67 m/s)	27.51 J

Magnetic elements are delicate – a strong collision with metal can result in shattering. Watch the impact speed – a magnet released freely turns into a projectile. Impact energy can cause material chips or painful pinches to fingers. Always hold the magnet during installation so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Wear eye protection when working with large magnets.

Rust risk: 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. However, remember the water resistance when pulling the rope quickly.

1. Wall mount (shear)

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

2. Steel thickness impact

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

3. Thermal stability

*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) = 0.50

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.

This product is an incredibly powerful cylindrical magnet, manufactured from modern NdFeB material, which, at dimensions of Ø50x20 mm, guarantees maximum efficiency. This specific item features high dimensional repeatability and industrial build quality, making it a perfect solution for professional engineers and designers. As a magnetic rod with significant force (approx. 70.10 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring quick order fulfillment. Moreover, its Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is created for building generators, advanced sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the high power of 687.66 N with a weight of only 294.52 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.

Due to the brittleness of the NdFeB material, you must not use force-fitting (so-called press-fit), as this risks immediate cracking of this precision component. To ensure stability in automation, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Magnets NdFeB grade N38 are suitable for 90% of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø50x20), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 50 mm and height 20 mm. The value of 687.66 N means that the magnet is capable of holding a weight many times exceeding its own mass of 294.52 g. 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 20 mm), which means that the N and S poles are located on the flat, circular surfaces. Thanks to this, the magnet can be easily glued into a hole and achieve a strong field on the front surface. On request, we can also produce versions magnetized diametrically if your project requires it.

Strengths and weaknesses of rare earth magnets.

Pros

Apart from their consistent holding force, neodymium magnets have these key benefits:

They have unchanged lifting capacity, and over around ten years their performance decreases symbolically – ~1% (in testing),
Magnets perfectly resist against loss of magnetization caused by ambient magnetic noise,
A magnet with a shiny gold surface looks better,
The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures approaching 230°C and above...
Possibility of exact forming as well as adjusting to concrete requirements,
Universal use in modern technologies – they are used in data components, drive modules, precision medical tools, as well as complex engineering applications.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Cons

Disadvantages of neodymium magnets:

To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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
Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
Limited possibility of making threads in the magnet and complicated forms - preferred is cover - magnetic holder.
Health risk to health – tiny shards of magnets are risky, when accidentally swallowed, which is particularly important in the context of child health protection. It is also worth noting that tiny parts of these products are able to complicate diagnosis medical when they are in the body.
Due to neodymium price, their price exceeds standard values,

Holding force characteristics

Highest magnetic holding force – what contributes to it?

The declared magnet strength represents the maximum value, obtained under optimal environment, namely:

on a base made of mild steel, optimally conducting the magnetic field
possessing a massiveness of min. 10 mm to ensure full flux closure
with a surface free of scratches
without the slightest air gap between the magnet and steel
for force applied at a right angle (pull-off, not shear)
at ambient temperature room level

Impact of factors on magnetic holding capacity in practice

In practice, the real power depends on several key aspects, ranked from crucial:

Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet holds much less (typically approx. 20-30% of maximum force).
Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
Plate material – mild steel attracts best. Alloy steels reduce magnetic permeability and holding force.
Plate texture – ground elements guarantee perfect abutment, which increases field saturation. Rough surfaces reduce efficiency.
Thermal conditions – NdFeB sinters have a negative temperature coefficient. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).

Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate lowers the lifting capacity.

H&S for magnets

Allergy Warning

Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If redness occurs, cease handling magnets and use protective gear.

Do not give to children

Strictly store magnets out of reach of children. Ingestion danger is high, and the consequences of magnets clamping inside the body are tragic.

Bone fractures

Large magnets can break fingers instantly. Do not put your hand betwixt two attracting surfaces.

Maximum temperature

Watch the temperature. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and pulling force.

Do not drill into magnets

Combustion risk: Neodymium dust is explosive. Do not process magnets in home conditions as this risks ignition.

Keep away from electronics

Navigation devices and smartphones are extremely sensitive to magnetic fields. Close proximity with a strong magnet can permanently damage the sensors in your phone.

Handling guide

Be careful. Neodymium magnets attract from a distance and snap with huge force, often quicker than you can move away.

Threat to electronics

Avoid bringing magnets near a wallet, computer, or TV. The magnetism can irreversibly ruin these devices and erase data from cards.

Warning for heart patients

People with a ICD must keep an large gap from magnets. The magnetism can disrupt the operation of the implant.

Shattering risk

Neodymium magnets are ceramic materials, which means they are very brittle. Impact of two magnets leads to them cracking into small pieces.
