Grip strength weakens drastically with every mm of gap. Keep in mind that every additional insulation layer (e.g., contamination, varnish, dust) significantly weakens the grip. Magnetic products hold most effectively during direct contact; gap drastically cuts the force. Notice how quickly the load capacity fall, when the product does not adhere tightly to the metal substrate. When calculating the assembly, eliminate redundant distances.

Table 2: Slippage load (wall)
MW 5x25 / N38

Distance (mm)	Friction coefficient	Pull Force (kg/lbs/g/N)
0 mm	Stal (~0.2)	0.09 kg / 0.20 pounds 90.0 g / 0.9 N

50 mm	Stal (~0.2)	0.00 kg / 0.00 pounds 0.0 g / 0.0 N

The table below calculates the approximate shear load sufficient to initiate the slippage of the magnet downwards along a upright metal surface (assuming typical friction coefficient). The holding force varies with the air gap between the magnet and the surface.

Table 3: Wall mounting (shearing) - vertical pull
MW 5x25 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.14 kg / 0.30 pounds 135.0 g / 1.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.09 kg / 0.20 pounds 90.0 g / 0.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.05 kg / 0.10 pounds 45.0 g / 0.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.23 kg / 0.50 pounds 225.0 g / 2.2 N

When placing a magnet on a vertical plane (e.g., a board), it will only hold only about 1/5 of its nominal power. Gravity as well as a low friction coefficient influence the fact that magnets move down easier than they detach. Want to create a vertical fastening? Note that the shear force is much weaker than the perpendicular breakaway force. On a painted metal, the holder will slide down under a much lighter weight. Using a rubber layer can significantly improve the result.

Table 4: Steel thickness (substrate influence) - power losses
MW 5x25 / N38

0.5 mm	10%	0.05 kg / 0.10 pounds 45.0 g / 0.4 N

2 mm	50%	0.23 kg / 0.50 pounds 225.0 g / 2.2 N
3 mm	75%	0.34 kg / 0.74 pounds 337.5 g / 3.3 N
5 mm	100%	0.45 kg / 0.99 pounds 450.0 g / 4.4 N
10 mm	100%	0.45 kg / 0.99 pounds 450.0 g / 4.4 N
11 mm	100%	0.45 kg / 0.99 pounds 450.0 g / 4.4 N
12 mm	100%	0.45 kg / 0.99 pounds 450.0 g / 4.4 N

A thin metal plate is not enough to focus the full magnetic flux, which squanders power of the magnet. If you attach a powerful product to a weak sheet, the magnetism will penetrate right through and the pull force will drop sharply. To squeeze the maximum of this magnet's potential, you require a sufficiently solid backing of metal. The material oversaturation means that on thin elements (e.g., appliance housings), the product holds weaker. We recommend selecting the steel thickness according to the table below.

Table 5: Thermal stability (stability) - thermal limit
MW 5x25 / N38

20 °C	0.0%	0.45 kg / 0.99 pounds 450.0 g / 4.4 N	OK
40 °C	-2.2%	0.44 kg / 0.97 pounds 440.1 g / 4.3 N	OK

Ordinary NdFeB products irreversibly lose power past the thermal threshold. Protect against heat – heat can irreversibly demagnetize this product. With increasing heat, the neodymium's power briefly lowers. Refrain from using this product near heat sources exceeding its working range. Exceeding the critical threshold will result in irreversible degradation of magnetism.

*Technical advisory: Heat tolerance is determined by both grade, but also on the magnet's shape. Flat magnets (low permeance coefficient) may lose charge permanently under lower heat stress than taller cylinders. Red status in the table points to permanent field degradation for this particular item.

Two strong neodymiums attract each other from a much further distance than a magnet and sheet combination. The setup of magnet-to-magnet generates a stronger field and a wider radius of operation. Want to build a powerful holder? Apply two magnets instead of a neodymium and a striker plate. Remember that when attracting two neodymiums, the collision energy is massive. The levitation is a bit weaker than the attraction, but still large.
*Flux density between like poles drops to ~0 Gs at the midpoint of the gap (resulting from vector opposition).
Note: Results apply to shear force of dual identical magnets (friction ~0.15 for Ni-Ni coating).

Table 7: Hazards (implants) - warnings
MW 5x25 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	5.0 cm

A strong magnetic field is a large risk to electronics as well as medical implants. These neodymiums produce a flux that prevents correct functioning of sensitive medical devices. Remember: the unseen radiation acts through matter and housings. Increased vigilance must be exercised by people with cochlear implants and drug dispensers. The risk also applies to: mechanical watches, remotes, membranes, and displays. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Table 8: Dynamics (cracking risk) - collision effects
MW 5x25 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	11.16 km/h (3.10 m/s)	0.02 J
30 mm	19.32 km/h (5.37 m/s)	0.05 J
50 mm	24.94 km/h (6.93 m/s)	0.09 J
100 mm	35.27 km/h (9.80 m/s)	0.18 J

Magnetic elements are very brittle – a strong collision with metal can result in shattering. Watch the impact speed – a magnet released freely speeds with massive force. Kinetic force can trigger coating fragments or dangerous crushing to fingers. Hold the magnet firmly during bringing near metal so it doesn't hit with great force against the steel surface. A collision at high speed means shattering of the neodymium. Use safety goggles when playing with large magnets.

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

Water displaces steel, making heavy objects slightly lighter. However, remember the water resistance when pulling the rope quickly.

1. Vertical hold

*Warning: On a vertical wall, the magnet retains only approx. 20-30% of its perpendicular strength.

2. Efficiency vs thickness

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

3. Heat tolerance

*For N38 material, the critical limit is 80°C.

4. Demagnetization curve and operating point (B-H)

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.55

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 incredibly powerful cylindrical magnet, composed of advanced NdFeB material, which, at dimensions of Ø5x25 mm, guarantees the highest energy density. This specific item is characterized by a tolerance of ±0.1mm and professional build quality, making it an ideal solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 0.45 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

It successfully proves itself in DIY projects, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 4.41 N with a weight of only 3.68 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.

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., 5.1 mm) using two-component epoxy glues. To ensure long-term durability in industry, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Grade N38 is the most popular standard for professional neodymium magnets, offering a great economic balance and high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø5x25), 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 Ø5x25 mm, which, at a weight of 3.68 g, makes it an element with high magnetic energy density. The value of 4.41 N means that the magnet is capable of holding a weight many times exceeding its own mass of 3.68 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 5 mm. Such an arrangement is standard when connecting magnets in stacks (e.g., in filters) or when mounting in sockets at the bottom of a hole. On request, we can also produce versions magnetized diametrically if your project requires it.

Pros and cons of Nd₂Fe₁₄B magnets.

Pros

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

They retain attractive force for around 10 years – the loss is just ~1% (based on simulations),
Magnets perfectly protect themselves against demagnetization caused by ambient magnetic noise,
By covering with a reflective coating of gold, the element acquires an proper look,
Neodymium magnets deliver maximum magnetic induction on a small area, which increases force concentration,
Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
Thanks to modularity in shaping and the capacity to customize to unusual requirements,
Key role in modern technologies – they are commonly used in hard drives, electric motors, medical equipment, as well as modern systems.
Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Limitations

Disadvantages of NdFeB magnets:

Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a special holder, which not only secures them against impacts but also increases their durability
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 and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in creating threads and complicated shapes in magnets, we propose using a housing - magnetic mechanism.
Health risk to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small components of these products can be problematic in diagnostics medical when they are in the body.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Pull force analysis

Optimal lifting capacity of a neodymium magnet – what it depends on?

Information about lifting capacity is the result of a measurement for optimal configuration, taking into account:

with the use of a sheet made of special test steel, guaranteeing full magnetic saturation
with a thickness no less than 10 mm
characterized by smoothness
without any insulating layer between the magnet and steel
during detachment in a direction vertical to the plane
at conditions approx. 20°C

Key elements affecting lifting force

During everyday use, the actual holding force is determined by several key aspects, presented from the most important:

Clearance – the presence of any layer (paint, dirt, gap) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
Plate thickness – insufficiently thick sheet does not accept the full field, causing part of the power to be lost to the other side.
Material type – the best choice is pure iron steel. Stainless steels may attract less.
Base smoothness – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
Temperature influence – high temperature weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.

Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.

H&S for magnets

Safe operation

Use magnets with awareness. Their powerful strength can surprise even experienced users. Plan your moves and respect their force.

Serious injuries

Big blocks can crush fingers instantly. Do not put your hand betwixt two attracting surfaces.

Fragile material

Protect your eyes. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.

Do not overheat magnets

Keep cool. NdFeB magnets are susceptible to heat. If you require operation above 80°C, ask us about HT versions (H, SH, UH).

Keep away from computers

Device Safety: Neodymium magnets can damage payment cards and sensitive devices (heart implants, hearing aids, mechanical watches).

Metal Allergy

Allergy Notice: The nickel-copper-nickel coating consists of nickel. If skin irritation happens, cease handling magnets and use protective gear.

Mechanical processing

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

Life threat

People with a pacemaker must keep an large gap from magnets. The magnetic field can stop the operation of the implant.

Phone sensors

A strong magnetic field negatively affects the operation of compasses in smartphones and GPS navigation. Do not bring magnets near a device to avoid breaking the sensors.

Swallowing risk

Always store magnets out of reach of children. Ingestion danger is high, and the consequences of magnets clamping inside the body are very dangerous.
