Grip strength weakens significantly with every mm of gap. Note that even a very thin break (e.g., contamination, varnish, rust) noticeably reduces the pull force. Neodymiums operate optimally at the point of direct contact; distance weakens the power. Observe how quickly the parameters drop, when the product does not adhere flatly to the metal substrate. When planning the mounting, avoid additional spacers.

The table below defines the approximate holding capacity sufficient to start the slippage of the magnet vertically along a vertical metal surface (assuming typical friction coefficient). This value is relative to the gap size between the magnet and the surface.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MW 10x4 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.84 kg / 1.85 lbs 840.0 g / 8.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.56 kg / 1.23 lbs 560.0 g / 5.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.28 kg / 0.62 lbs 280.0 g / 2.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.40 kg / 3.09 lbs 1400.0 g / 13.7 N

When placing a element on a vertical plane (e.g., a board), it will maintain only approx. 1/5 of nominal attraction strength. Gravity as well as a weak degree of grip cause that holders slip easier than they pull off. Planning a wall mount? Remember that the sliding force is significantly lower than the perpendicular breakaway force. On a smooth steel, the holder will slide down under a significantly smaller cargo. Application of an anti-slip coating can significantly improve the result.

12 mm	100%	2.80 kg / 6.17 lbs 2800.0 g / 27.5 N

A too thin steel is unable to conduct the full magnetic flux, which weakens actual performance of the magnet. If you mount a strong magnet to a weak sheet, the field will penetrate right through and the holding will be smaller. To squeeze 100% of this neodymium's potential, you require a sufficiently solid element of steel. The saturation phenomenon means that on sheet metal structures (e.g., car bodies), the magnet works worse. We advise picking the steel dimension from these parameters.

Table 5: Working in heat (stability) - resistance threshold
MW 10x4 / N38

Ambient temp. (°C)	Power loss	Remaining pull (kg/lbs/g/N)	Status
20 °C	0.0%	2.80 kg / 6.17 lbs 2800.0 g / 27.5 N	OK
40 °C	-2.2%	2.74 kg / 6.04 lbs 2738.4 g / 26.9 N	OK
60 °C	-4.4%	2.68 kg / 5.90 lbs 2676.8 g / 26.3 N
80 °C	-6.6%	2.62 kg / 5.77 lbs 2615.2 g / 25.7 N
100 °C	-28.8%	1.99 kg / 4.40 lbs 1993.6 g / 19.6 N

Standard neodymium magnets change their properties strength above the temperature limit. Avoid high temperatures – high temperature can irreversibly demagnetize this magnet. As the temperature rises, the neodymium's force briefly lowers. Do not use this magnet near heat sources higher than its working range. Ignoring the limit will result in destruction of magnetic properties.

*Important note: Heat tolerance is determined by both grade, as well as the dimension ratios. Low-profile magnets (low permeance coefficient) risk losing magnetic properties under lower heat stress than taller cylinders. Red status in the table points to permanent field degradation for this specific geometry.

Two magnetic products attract each other from a wider radius than a magnet and sheet combination. The connection of magnet-to-magnet generates a stronger field and a larger range of action. Designing a powerful holder? Use a pair of magnets instead of one magnet and a steel. Exercise caution that when attracting two neodymiums, the collision energy is huge. The repulsion force is marginally weaker than the attraction, but still large.
*The magnetic induction between like poles reaches ~0 Gs at the midpoint of the gap (resulting from vector opposition).
* Figures demonstrate shear force of two same neodymium magnets (friction ~0.15 for Ni-Ni layer).

Powerful magnet radiation poses a real danger to IT equipment and pacemakers. These NdFeB products generate a flux that disrupts operation of digital equipment. Remember: the invisible magnetic field penetrates the body and plastic. Exceptional care must be taken by people with cochlear implants and insulin pumps. Also at risk are: automatic timepieces, remotes, speakers, and screens. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

Magnetic elements are delicate – a strong collision with metal causes immediate chipping. Control the attraction moment – a magnet released freely speeds with massive force. Striking energy can destroy the magnet or dangerous crushing to fingers. Always hold the magnet during mounting so it doesn't slam with momentum against the steel surface. A collision at high speed ends with a crack of the magnet. Wear safety glasses when playing with large magnets.

Corrosion warning: 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. Buoyancy helps in lifting finds.

1. Wall mount (shear)

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

2. Plate thickness effect

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

3. Power loss vs temp

*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) = 0.50

This simulation demonstrates the magnetic stability of the selected magnet under specific geometric conditions. 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 exceptionally strong cylinder magnet, composed of modern NdFeB material, which, with dimensions of Ø10x4 mm, guarantees optimal power. The MW 10x4 / N38 component boasts a tolerance of ±0.1mm and professional build quality, making it an excellent solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 2.80 kg), this product is available off-the-shelf from our European logistics center, ensuring quick order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is perfect for building electric motors, advanced sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the high power of 27.42 N with a weight of only 2.36 g, this rod is indispensable in miniature devices and wherever low weight is crucial.

Since our magnets have a tolerance of ±0.1mm, the best method is to glue them into holes with a slightly larger diameter (e.g., 10.1 mm) using two-component epoxy glues. To ensure long-term durability in industry, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Magnets 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 even stronger magnets in the same volume (Ø10x4), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

This model is characterized by dimensions Ø10x4 mm, which, at a weight of 2.36 g, makes it an element with high magnetic energy density. The value of 27.42 N means that the magnet is capable of holding a weight many times exceeding its own mass of 2.36 g. The product has a [NiCuNi] coating, which secures it against oxidation, 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 10 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.

Advantages and disadvantages of Nd₂Fe₁₄B magnets.

Strengths

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

Their strength remains stable, and after approximately 10 years it drops only by ~1% (theoretically),
They feature excellent resistance to magnetism drop as a result of external fields,
By covering with a lustrous layer of silver, the element gains an proper look,
Magnetic induction on the working part of the magnet turns out to be exceptional,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
Thanks to flexibility in shaping and the capacity to customize to individual projects,
Wide application in modern technologies – they serve a role in data components, electromotive mechanisms, precision medical tools, also modern systems.
Thanks to their power density, small magnets offer high operating force, occupying minimum space,

Weaknesses

Disadvantages of NdFeB magnets:

They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
Due to limitations in realizing nuts and complex shapes in magnets, we propose using cover - magnetic mechanism.
Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the context of child safety. Additionally, small elements of these devices are able to 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

Lifting parameters

Maximum holding power of the magnet – what affects it?

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

on a plate made of structural steel, effectively closing the magnetic flux
whose transverse dimension equals approx. 10 mm
with an polished touching surface
under conditions of no distance (metal-to-metal)
during pulling in a direction vertical to the plane
at temperature room level

Magnet lifting force in use – key factors

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

Gap (betwixt the magnet and the metal), as even a microscopic distance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to paint, rust or debris).
Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
Base massiveness – too thin steel causes magnetic saturation, causing part of the flux to be escaped into the air.
Metal type – not every steel attracts identically. High carbon content worsen the interaction with the magnet.
Base smoothness – the more even the plate, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
Thermal factor – hot environment reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under shearing force the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.

Precautions when working with NdFeB magnets

Do not underestimate power

Be careful. Rare earth magnets act from a long distance and connect with huge force, often quicker than you can react.

Demagnetization risk

Keep cool. Neodymium magnets are susceptible to temperature. If you need resistance above 80°C, inquire about special high-temperature series (H, SH, UH).

Cards and drives

Data protection: Strong magnets can ruin payment cards and sensitive devices (pacemakers, hearing aids, mechanical watches).

Magnet fragility

Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.

Dust explosion hazard

Powder created during machining of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.

Phone sensors

GPS units and mobile phones are highly susceptible to magnetism. Close proximity with a powerful NdFeB magnet can ruin the internal compass in your phone.

Allergy Warning

Nickel alert: The nickel-copper-nickel coating contains nickel. If an allergic reaction happens, cease handling magnets and wear gloves.

Bone fractures

Large magnets can crush fingers instantly. Do not put your hand between two strong magnets.

Health Danger

Medical warning: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.

This is not a toy

Absolutely keep magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets connecting inside the body are life-threatening.
