Pulling power decreases significantly with every subsequent millimeter of gap. Note that even a very thin break (e.g., dirt, paint, rust) significantly weakens the grip. Magnetic products work most effectively during direct contact; gap drastically cuts the force. See how quickly the pull force drop, when the magnet does not touch tightly to the steel surface. When planning the arrangement, discard additional spacers.

The following data defines the estimated shear load needed to start the slippage of the magnet downwards along a upright steel wall (considering standard friction coefficient). The holding force is relative to the separation distance between the magnet and the metal.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MW 25x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.39 kg / 5.28 lbs 2394.0 g / 23.5 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.60 kg / 3.52 lbs 1596.0 g / 15.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.80 kg / 1.76 lbs 798.0 g / 7.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	3.99 kg / 8.80 lbs 3990.0 g / 39.1 N

When hanging a magnet on a vertical plane (e.g., a board), it will maintain just approx. 1/5 of nominal attraction strength. Gravity as well as a low friction coefficient mean that products move down faster than they pop off the substrate. Planning a vertical fastening? Note that the shear force is much weaker than the perpendicular breakaway force. On a smooth steel, the magnet will slip down under a noticeably lighter load. Using a rubber pad can significantly raise the stability.

MW 25x5 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	10%	0.80 kg / 1.76 lbs 798.0 g / 7.8 N

2 mm	50%	3.99 kg / 8.80 lbs 3990.0 g / 39.1 N
3 mm	75%	5.99 kg / 13.19 lbs 5985.0 g / 58.7 N
5 mm	100%	7.98 kg / 17.59 lbs 7980.0 g / 78.3 N
10 mm	100%	7.98 kg / 17.59 lbs 7980.0 g / 78.3 N
11 mm	100%	7.98 kg / 17.59 lbs 7980.0 g / 78.3 N
12 mm	100%	7.98 kg / 17.59 lbs 7980.0 g / 78.3 N

A too thin steel cannot focus the full magnetic flux, which squanders power of the magnet. Should you install a neodymium to a too thin substrate, the magnetism will pass right through and the attraction force will be weaker. To utilize the maximum of this neodymium's potential, you require a sufficiently solid piece of metal. The saturation effect means that on sheet metal structures (e.g., car bodies), the product works worse. We suggest choosing the steel thickness according to the table below.

Table 5: Thermal resistance (stability) - resistance threshold
MW 25x5 / N38

Ambient temp. (°C)	Power loss	Remaining pull (kg/lbs/g/N)	Status
20 °C	0.0%	7.98 kg / 17.59 lbs 7980.0 g / 78.3 N	OK
40 °C	-2.2%	7.80 kg / 17.21 lbs 7804.4 g / 76.6 N	OK
60 °C	-4.4%	7.63 kg / 16.82 lbs 7628.9 g / 74.8 N
80 °C	-6.6%	7.45 kg / 16.43 lbs 7453.3 g / 73.1 N
100 °C	-28.8%	5.68 kg / 12.53 lbs 5681.8 g / 55.7 N

Ordinary NdFeB products irreversibly lose power after exceeding the maximum temperature. Avoid high temperatures – excessive heat can irreversibly damage this magnet. As the temperature rises, the neodymium's force temporarily decreases. Do not use this magnet close to ovens higher than its operating temperature limit. Too high temperature will cause destruction of magnetism.

*Technical advisory: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Low-profile magnets (low permeance coefficient) risk losing magnetic properties under lower heat stress compared to rod magnets. Red status in the table signals a risk of irreversible loss for this particular item.

Two magnetic products attract each other from a significantly greater distance than a neodymium and metal setup. The connection of magnet-to-magnet creates a more powerful interaction and a further horizon of performance. Planning to create a solid fastener? Utilize two neodymiums instead of a neodymium and a steel. Be careful that when attracting two neodymiums, the pinch force is massive. The repulsion force is a bit weaker than the connection force, but still significant.
*Field value in repulsion mode drops to ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
Note: Results refer to friction force of two matching magnets (friction ~0.15 for Ni-Ni plating).

A strong magnetic field poses a serious hazard to electronics and medical implants. These NdFeB products generate a flux that prevents correct functioning of digital equipment. Notice: the invisible magnetic field passes through tissues and plastic. Increased vigilance must be exercised by people with hearing aids and drug dispensers. Influence will be felt by: automatic timepieces, remotes, membranes, and displays. Do not place the magnet near cards, HDD media, or precise measuring instruments.

Neodymium magnets are very brittle – a collision with steel can result in shattering. Control the attraction moment – a neodymium left loose speeds with massive force. Striking energy can cause material chips or injury to skin. Always hold the magnet during bringing near metal so it doesn't hit violently against the metal. A collision at high speed ends with a crack of the magnet. Wear safety glasses when handling with powerful specimens.

Corrosion 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. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Wall mount (shear)

*Caution: On a vertical wall, the magnet retains merely a fraction of its nominal pull.

2. Steel saturation

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

3. Heat tolerance

*For N38 material, 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) = 0.29

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 extremely powerful rod magnet, made from durable NdFeB material, which, at dimensions of Ø25x5 mm, guarantees optimal power. The MW 25x5 / N38 model boasts an accuracy of ±0.1mm and professional build quality, making it an excellent solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 7.98 kg), this product is in stock from our European logistics center, ensuring quick order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

This model is created for building electric motors, advanced sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the high power of 78.25 N with a weight of only 18.41 g, this cylindrical magnet is indispensable in miniature devices 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., 25.1 mm) using two-component epoxy glues. To ensure stability in automation, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most popular standard for industrial neodymium magnets, offering a great economic balance and high resistance to demagnetization. If you need even stronger magnets in the same volume (Ø25x5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 25 mm and height 5 mm. The value of 78.25 N means that the magnet is capable of holding a weight many times exceeding its own mass of 18.41 g. The product has a [NiCuNi] coating, which secures it against external factors, 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 25 mm. 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.

Pros as well as cons of neodymium magnets.

Benefits

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

They have stable power, and over more than ten years their performance decreases symbolically – ~1% (in testing),
They have excellent resistance to weakening of magnetic properties when exposed to external magnetic sources,
By covering with a decorative coating of nickel, the element gains an professional look,
Magnets are distinguished by very high magnetic induction on the outer side,
Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
Possibility of individual shaping and optimizing to complex requirements,
Huge importance in high-tech industry – they find application in mass storage devices, motor assemblies, diagnostic systems, and modern systems.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which enables their usage in compact constructions

Weaknesses

Characteristics of disadvantages of neodymium magnets and proposals for their use:

They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as 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 rust. Therefore during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
Limited ability of making threads in the magnet and complicated shapes - preferred is cover - mounting mechanism.
Potential hazard related to microscopic parts of magnets can be dangerous, in case of ingestion, which gains importance in the aspect of protecting the youngest. Additionally, small components of these products can complicate diagnosis medical in case of swallowing.
With large orders the cost of neodymium magnets is a challenge,

Pull force analysis

Optimal lifting capacity of a neodymium magnet – what affects it?

Breakaway force was defined for the most favorable conditions, assuming:

with the use of a sheet made of special test steel, ensuring maximum field concentration
with a cross-section of at least 10 mm
characterized by lack of roughness
without the slightest air gap between the magnet and steel
under axial force direction (90-degree angle)
at ambient temperature room level

Magnet lifting force in use – key factors

Bear in mind that the working load will differ depending on elements below, in order of importance:

Clearance – the presence of any layer (paint, dirt, air) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Steel grade – ideal substrate is high-permeability steel. Stainless steels may generate lower lifting capacity.
Surface quality – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
Thermal factor – hot environment reduces pulling force. Too high temperature can permanently damage the magnet.

Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, whereas under attempts to slide the magnet the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate reduces the load capacity.

Precautions when working with neodymium magnets

Immense force

Be careful. Neodymium magnets act from a distance and connect with massive power, often quicker than you can move away.

Danger to the youngest

These products are not suitable for play. Accidental ingestion of several magnets can lead to them connecting inside the digestive tract, which poses a critical condition and necessitates immediate surgery.

Maximum temperature

Avoid heat. Neodymium magnets are susceptible to heat. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).

Avoid contact if allergic

It is widely known that the nickel plating (the usual finish) is a common allergen. For allergy sufferers, avoid direct skin contact or select coated magnets.

Health Danger

For implant holders: Powerful magnets disrupt medical devices. Maintain minimum 30 cm distance or ask another person to work with the magnets.

Magnet fragility

Protect your eyes. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.

Bone fractures

Watch your fingers. Two large magnets will join immediately with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!

Precision electronics

A strong magnetic field interferes with the operation of magnetometers in smartphones and navigation systems. Keep magnets close to a device to avoid damaging the sensors.

Do not drill into magnets

Combustion risk: Rare earth powder is explosive. Do not process magnets without safety gear as this may cause fire.

Protect data

Very strong magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Stay away of min. 10 cm.

Caution! Learn more about risks in the article: Safety of working with magnets.
