Grip strength drops sharply with every subsequent millimeter of distance. Keep in mind that even a very thin break (e.g., contamination, varnish, dust) noticeably diminishes the holding power. Magnetic products work strongest in perfect adhesion; air break drastically cuts the power. Analyze how quickly the load capacity drop, when the product does not touch directly to the metal substrate. When calculating the arrangement, discard unnecessary gaps.

This section calculates the estimated force necessary to start the slippage of the magnet vertically against a upright steel wall (assuming typical friction). The holding force is a function of the gap size between the magnet and the metal.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MW 12.5x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.43 kg / 0.94 pounds 426.0 g / 4.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.28 kg / 0.63 pounds 284.0 g / 2.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.14 kg / 0.31 pounds 142.0 g / 1.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.71 kg / 1.57 pounds 710.0 g / 7.0 N

When placing a element on a vertical plane (e.g., a board), it will only hold just approx. 1/5 of its maximum pull force. Gravitational force and a weak degree of grip mean that magnets slide down easier than they detach. Designing a hanger? Remember that the sliding force is much weaker than the perpendicular breakaway force. On a painted metal, the holder will give way down under a significantly smaller weight. Utilizing a rubberized coating can significantly increase the grip.

12 mm	100%	1.42 kg / 3.13 pounds 1420.0 g / 13.9 N

A thin metal plate is incapable of conduct the entire magnetic field, which wastes potential of the magnet. If you mount a strong magnet to a too thin substrate, the field will pass right through and the holding will be smaller. To squeeze 100% of this neodymium's potential, you need a suitably thick piece of metal. The material oversaturation causes that on sheet metal structures (e.g., appliance housings), the magnet shows lower pull force. We recommend selecting the steel dimension from these parameters.

Classic neodymiums irreversibly lose strength after exceeding the maximum temperature. Avoid high temperatures – heat can irreversibly destroy this magnet. As the temperature rises, the magnet's power momentarily lowers. Avoid using this product close to ovens higher than its working range. Exceeding the critical threshold will result in destruction of magnetism.

*Engineering note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Low-profile magnets (pancake types) may lose charge permanently under lower heat stress than taller cylinders. Warning indicator in the table points to a risk of irreversible loss for this specific geometry.

Two magnetic products attract each other from a significantly greater distance than a magnet and steel combination. The connection of magnet-to-magnet generates a stronger field and a larger range of operation. Designing a strong closure? Utilize two neodymiums instead of a neodymium and a steel. Be careful that when connecting a pair of magnets, the impact force is huge. The repulsion force is slightly lower than the connection force, but still significant.
*Flux density between like poles drops to ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
* Results show friction force of two same neodymium magnets (friction ~0.15 for Ni-Ni layer).

Table 7: Hazards (implants) - precautionary measures
MW 12.5x2 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	4.5 cm
Hearing aid	10 Gs (1.0 mT)	3.5 cm

Extremely neodym field is a serious hazard to electronic devices as well as pacemakers. These neodymiums generate a field that prevents correct functioning of sensitive medical devices. Remember: the invisible magnetic field penetrates the body and plastic. Special caution must be exercised by people with cochlear implants and insulin pumps. The risk also applies to: automatic timepieces, remotes, membranes, and displays. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Table 8: Impact energy (kinetic energy) - collision effects
MW 12.5x2 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	28.30 km/h (7.86 m/s)	0.06 J
30 mm	48.53 km/h (13.48 m/s)	0.17 J
50 mm	62.65 km/h (17.40 m/s)	0.28 J
100 mm	88.60 km/h (24.61 m/s)	0.56 J

Neodymium magnets are prone to chipping – a strong collision with metal risks their cracking. Control the attraction moment – a magnet released freely becomes dangerous. Kinetic force can cause material chips or injury to skin. Hold the magnet firmly during bringing near metal so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Use safety goggles when handling with powerful specimens.

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

The magnetic field penetrates through water without any losses. Buoyancy helps in lifting finds.

1. Wall mount (shear)

*Note: On a vertical wall, the magnet holds just approx. 20-30% of its perpendicular strength.

2. Efficiency vs thickness

*Thin metal sheet (e.g. 0.5mm PC case) severely weakens the holding force.

3. Power loss vs temp

*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) = 0.24

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 extremely powerful cylinder magnet, manufactured from durable NdFeB material, which, with dimensions of Ø12.5x2 mm, guarantees the highest energy density. The MW 12.5x2 / N38 component boasts a tolerance 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. 1.42 kg), this product is in stock from our warehouse in Poland, ensuring rapid order fulfillment. Moreover, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

It finds application in DIY projects, advanced automation, and broadly understood industry, serving as a fastening or actuating element. Thanks to the high power of 13.89 N with a weight of only 1.84 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 long-term durability 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 suitable for the majority of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø12.5x2), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 12.5 mm and height 2 mm. The key parameter here is the holding force amounting to approximately 1.42 kg (force ~13.89 N), which, with such compact dimensions, proves the high power of the NdFeB material. 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 2 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 Nd₂Fe₁₄B magnets.

Pros

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

They have constant strength, and over more than ten years their attraction force decreases symbolically – ~1% (according to theory),
They have excellent resistance to magnetic field loss as a result of external fields,
In other words, due to the smooth layer of nickel, the element gains visual value,
They feature high magnetic induction at the operating surface, which affects their effectiveness,
Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
Possibility of detailed forming and modifying to concrete requirements,
Fundamental importance in high-tech industry – they are utilized in magnetic memories, motor assemblies, diagnostic systems, as well as modern systems.
Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Disadvantages

Disadvantages of NdFeB magnets:

They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only shields the magnet but also increases 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 durability even at temperatures up to 230°C
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
Limited ability of creating threads in the magnet and complicated shapes - preferred is a housing - mounting mechanism.
Health risk resulting from small fragments of magnets are risky, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Furthermore, tiny parts of these products can be problematic in diagnostics medical in case of swallowing.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

Maximum holding power of the magnet – what affects it?

The force parameter is a result of laboratory testing executed under the following configuration:

on a block made of structural steel, perfectly concentrating the magnetic field
whose thickness reaches at least 10 mm
with an polished contact surface
without the slightest air gap between the magnet and steel
during pulling in a direction perpendicular to the plane
in temp. approx. 20°C

Magnet lifting force in use – key factors

In real-world applications, the actual lifting capacity is determined by several key aspects, ranked from the most important:

Clearance – existence of any layer (rust, dirt, air) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
Material type – the best choice is high-permeability steel. Hardened steels may have worse magnetic properties.
Smoothness – full contact is possible only on polished steel. Rough texture create air cushions, weakening the magnet.
Thermal factor – high temperature weakens magnetic field. Too high temperature can permanently demagnetize the magnet.

Lifting capacity was measured using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate lowers the load capacity.

Safe handling of neodymium magnets

Magnet fragility

Despite the nickel coating, the material is brittle and not impact-resistant. Do not hit, as the magnet may shatter into hazardous fragments.

Heat warning

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

Impact on smartphones

An intense magnetic field negatively affects the functioning of compasses in smartphones and GPS navigation. Maintain magnets close to a device to avoid damaging the sensors.

Allergic reactions

Allergy Notice: The Ni-Cu-Ni coating contains nickel. If skin irritation happens, cease working with magnets and use protective gear.

Keep away from computers

Equipment safety: Neodymium magnets can damage data carriers and sensitive devices (heart implants, hearing aids, mechanical watches).

Crushing force

Protect your hands. Two powerful magnets will snap together instantly with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!

ICD Warning

Warning for patients: Strong magnetic fields disrupt electronics. Keep at least 30 cm distance or ask another person to work with the magnets.

Fire warning

Powder produced during cutting of magnets is self-igniting. Do not drill into magnets unless you are an expert.

Immense force

Handle with care. Neodymium magnets attract from a distance and connect with massive power, often faster than you can move away.

Product not for children

NdFeB magnets are not intended for children. Accidental ingestion of a few magnets may result in them attracting across intestines, which constitutes a severe health hazard and requires immediate surgery.
