Pulling power decreases sharply with every subsequent millimeter of spacing. Keep in mind that even a microscopic distance (e.g., dirt, varnish, veneer) noticeably diminishes the holding power. Magnets operate optimally at the point of direct contact; gap nullifies the force. Notice how quickly the load capacity drop, when the magnet does not adhere directly to the metal substrate. When calculating the arrangement, discard unnecessary gaps.

The table below defines the approximate weight limit needed to cause the downward movement of the magnet downwards along a upright steel wall (assuming standard friction coefficient). The holding force is relative to the separation distance between the magnet and the metal.

Table 3: Wall mounting (shearing) - vertical pull
MW 25x6 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	3.08 kg / 6.79 LBS 3081.0 g / 30.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	2.05 kg / 4.53 LBS 2054.0 g / 20.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	1.03 kg / 2.26 LBS 1027.0 g / 10.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	5.14 kg / 11.32 LBS 5135.0 g / 50.4 N

When placing a magnet on a vertical wall (e.g., a fridge), it you can count on barely about 20%-30% of nominal attraction strength. Gravity and a weak degree of grip influence the fact that products slip faster than they pull off. Planning a vertical fastening? Note that the sliding force is much weaker than the maximum static pull force. On a smooth steel, the element will slip down under a significantly smaller cargo. Utilizing a rubberized layer can significantly raise the stability.

A thin metal plate cannot absorb the full magnetic flux, which squanders power of the magnet. Should you attach a powerful product to a too thin substrate, the field will pass right through and the pull force will drop sharply. To achieve the maximum of this magnet's power, you need a suitably thick piece of metal. The saturation phenomenon causes that on sheet metal structures (e.g., thin profiles), the product works worse. We advise picking the steel dimension according to the table below.

Ordinary NdFeB products change their properties power above the temperature limit. Protect against heat – excessive heat can irreversibly demagnetize this product. With every degree above norm, the magnet's capacity briefly lowers. Do not use this magnet close to heaters higher than its working range. Ignoring the limit will result in irreversible degradation of magnetism.

*Technical advisory: Temperature resistance is determined by both grade, but also on the magnet's shape. Thin magnets (low Pc) risk losing magnetic properties under lower heat stress compared to rod magnets. Warning indicator in the table signals permanent field degradation for this specific geometry.

Two magnets interact from a significantly greater distance than a magnet and steel combination. The connection of magnet-to-magnet produces a massive flux and a further horizon of action. Planning to create a powerful holder? Apply two magnets instead of one magnet and a steel. Remember that when attracting two neodymiums, the collision energy is massive. The repulsion force is marginally weaker than the connection force, but still impressive.
*Field value between like poles is approximately ~0 Gs at the geometric center of the gap (resulting from vector opposition).
Note: Estimates show friction force of a pair of identical magnets (friction coefficient ~0.15 for Ni-Ni layer).

Table 7: Safety (HSE) (implants) - precautionary measures

Extremely neodym field poses a large risk to IT equipment and pacemakers. These magnets generate a field that destroys function of digital equipment. Remember: the invisible magnetic field acts through matter and plastic. Increased vigilance must be taken by people with cochlear implants and insulin pumps. Also at risk are: mechanical watches, remotes, speakers, and displays. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

Table 8: Impact energy (cracking risk) - warning

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	23.60 km/h (6.56 m/s)	0.47 J
30 mm	37.72 km/h (10.48 m/s)	1.21 J

100 mm	68.77 km/h (19.10 m/s)	4.03 J

Magnetic elements are prone to chipping – a strong collision with metal causes immediate chipping. Pay attention to connection velocity – a magnet released freely turns into a projectile. Striking energy can destroy the magnet or dangerous crushing to fingers. Be sure to control the product during mounting so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Wear eye protection when handling with large magnets.

Rust risk: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

The magnetic field penetrates through water without any losses. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Wall mount (shear)

*Note: On a vertical surface, the magnet retains just a fraction of its nominal pull.

2. Efficiency vs thickness

*Thin metal sheet (e.g. 0.5mm PC 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) = 0.34

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.

This product is a very strong cylindrical magnet, composed of modern NdFeB material, which, at dimensions of Ø25x6 mm, guarantees optimal power. This specific item is characterized by an accuracy of ±0.1mm and professional build quality, making it an ideal solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 10.27 kg), this product is available off-the-shelf from our European logistics center, ensuring rapid order fulfillment. Additionally, its Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is perfect for building generators, advanced Hall effect sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the pull force of 100.71 N with a weight of only 22.09 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.

Since our magnets have a tolerance of ±0.1mm, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 25.1 mm) using epoxy glues. To ensure stability in industry, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most frequently chosen standard for industrial neodymium magnets, offering an optimal price-to-power ratio and operational stability. If you need the strongest magnets in the same volume (Ø25x6), 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 25 mm and height 6 mm. The value of 100.71 N means that the magnet is capable of holding a weight many times exceeding its own mass of 22.09 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 6 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.

Advantages as well as disadvantages of Nd₂Fe₁₄B magnets.

Benefits

Besides their exceptional pulling force, neodymium magnets offer the following advantages:

They do not lose power, even after around ten years – the reduction in strength is only ~1% (based on measurements),
They are noted for resistance to demagnetization induced by presence of other magnetic fields,
The use of an metallic coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
Neodymium magnets achieve maximum magnetic induction on a small surface, which allows for strong attraction,
Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures reaching 230°C and above...
In view of the possibility of flexible molding and adaptation to specialized requirements, neodymium magnets can be produced in a variety of shapes and sizes, which increases their versatility,
Key role in electronics industry – they find application in hard drives, electromotive mechanisms, advanced medical instruments, and other advanced devices.
Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which makes them useful in compact constructions

Weaknesses

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

They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
Neodymium magnets lose their force 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 durability even at temperatures up to 230°C
Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
Limited possibility of producing threads in the magnet and complicated shapes - recommended is a housing - mounting mechanism.
Potential hazard to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, tiny parts of these products can disrupt the diagnostic process medical when they are in the body.
With mass production the cost of neodymium magnets is economically unviable,

Pull force analysis

Maximum holding power of the magnet – what affects it?

The specified lifting capacity refers to the peak performance, recorded under optimal environment, meaning:

with the application of a yoke made of special test steel, guaranteeing maximum field concentration
possessing a thickness of minimum 10 mm to avoid saturation
with a plane cleaned and smooth
without any clearance between the magnet and steel
under axial application of breakaway force (90-degree angle)
at standard ambient temperature

Determinants of lifting force in real conditions

It is worth knowing that the application force may be lower depending on the following factors, starting with the most relevant:

Gap (between the magnet and the plate), since even a tiny clearance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
Direction of force – highest force is available only during pulling at a 90° angle. The force required to slide of the magnet along the plate is standardly many times lower (approx. 1/5 of the lifting capacity).
Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
Steel grade – the best choice is high-permeability steel. Hardened steels may generate lower lifting capacity.
Surface condition – ground elements guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
Temperature influence – high temperature reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity was assessed with the use of a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas 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 decreases the holding force.

Precautions when working with neodymium magnets

Risk of cracking

NdFeB magnets are sintered ceramics, meaning they are prone to chipping. Clashing of two magnets will cause them breaking into shards.

Choking Hazard

Neodymium magnets are not suitable for play. Swallowing several magnets may result in them attracting across intestines, which constitutes a direct threat to life and requires urgent medical intervention.

Dust is flammable

Machining of neodymium magnets poses a fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.

Keep away from electronics

Be aware: rare earth magnets produce a field that confuses precision electronics. Maintain a safe distance from your mobile, tablet, and GPS.

Implant safety

Warning for patients: Powerful magnets disrupt medical devices. Maintain minimum 30 cm distance or request help to handle the magnets.

Permanent damage

Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.

Electronic hazard

Very strong magnetic fields can corrupt files on payment cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.

Allergy Warning

Allergy Notice: The nickel-copper-nickel coating contains nickel. If skin irritation appears, cease handling magnets and wear gloves.

Crushing risk

Big blocks can break fingers instantly. Never put your hand between two strong magnets.

Powerful field

Before starting, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
