Pulling power decreases sharply with every mm of distance. Keep in mind that even the smallest gap (e.g., contamination, varnish, veneer) noticeably weakens the grip. Neodymiums operate most effectively at the point of direct contact; distance weakens the force. Observe how flashily the parameters plummet, when the magnet does not adhere directly to the metal substrate. When planning the mounting, avoid redundant distances.

This section defines the estimated shear load sufficient to cause the sliding of the magnet down on a vertical steel wall (assuming typical friction coefficient). The holding force is a function of the distance between the magnet and the surface.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MW 25x2.5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.76 kg / 1.69 LBS 765.0 g / 7.5 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.51 kg / 1.12 LBS 510.0 g / 5.0 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.26 kg / 0.56 LBS 255.0 g / 2.5 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.28 kg / 2.81 LBS 1275.0 g / 12.5 N

When mounting a holder on a upright plane (e.g., a car body), it will maintain only approx. 1/5 of its nominal power. Gravitational force as well as a weak degree of grip cause that products slide down faster than they pull off. Planning a hanger? Remember that the sliding force is noticeably lower than the maximum static pull force. On a smooth steel, the magnet will slip down under a noticeably lighter cargo. Utilizing a rubberized layer can drastically increase the grip.

12 mm	100%	2.55 kg / 5.62 LBS 2550.0 g / 25.0 N

A thin sheet cannot absorb the full magnetic flux, which weakens actual performance of the holder. Should you attach a powerful product to a too thin substrate, the field will pass right through and the holding will be smaller. To utilize full efficiency of this magnet's power, you need a suitably thick backing of metal. The material oversaturation means that on thin elements (e.g., car bodies), the magnet shows lower pull force. We recommend selecting the steel dimension based on the following data.

Standard neodymium magnets irreversibly lose strength past the thermal threshold. Avoid high temperatures – excessive heat can irreversibly destroy this magnet. With increasing heat, the neodymium's force briefly decreases. Avoid using this magnet close to heaters higher than its safe range. Exceeding the critical threshold will cause permanent loss of magnetism.

*Important note: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Low-profile magnets (low Pc) may lose charge permanently sooner compared to rod magnets. The danger warning in the table points to permanent field degradation for this particular item.

Two strong neodymiums interact from a much further distance than a magnet and steel setup. Such a system of two magnets generates a stronger field and a wider radius of operation. Planning to create a powerful holder? Use a pair of magnets instead of a neodymium and a steel. Remember that when connecting a pair of magnets, the pinch force is extreme. The repulsion force is a bit weaker than the connection force, but still impressive.
*Field value in repulsion mode reaches ~0 Gs at the geometric center between the magnets (resulting from vector opposition).
Note: Results demonstrate sliding force of a pair of identical neodymium magnets (friction ~0.15 for Ni-Ni coating).

Powerful magnet radiation poses a real danger to electronics as well as pacemakers. These neodymiums produce a field that disrupts operation of digital equipment. Notice: the invisible magnetic field acts through matter and glass. Increased vigilance must be taken by people with hearing aids and drug dispensers. Also at risk are: mechanical watches, remotes, membranes, and screens. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Table 8: Collisions (cracking risk) - collision effects

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	18.55 km/h (5.15 m/s)	0.12 J

50 mm	37.55 km/h (10.43 m/s)	0.50 J
100 mm	53.10 km/h (14.75 m/s)	1.00 J

Magnetic elements are very brittle – a collision with steel risks their cracking. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Striking energy can cause material chips or dangerous crushing to fingers. Always hold the magnet during installation so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Wear safety glasses when playing with powerful specimens.

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

1. Vertical hold

*Caution: On a vertical surface, the magnet holds just ~20% of its max power.

2. Steel saturation

*Thin metal sheet (e.g. computer case) significantly reduces the holding force.

3. Thermal stability

*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) = 0.16

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 exceptionally strong rod magnet, made from modern NdFeB material, which, with dimensions of Ø25x2.5 mm, guarantees optimal power. The MW 25x2.5 / N38 model features an accuracy of ±0.1mm and industrial build quality, making it an excellent solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 2.55 kg), this product is available off-the-shelf from our European logistics center, ensuring quick order fulfillment. Additionally, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

It finds application in modeling, advanced automation, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 25.03 N with a weight of only 9.2 g, this cylindrical magnet is indispensable in electronics and wherever low weight is crucial.

Due to the delicate structure of the ceramic sinter, we absolutely advise against force-fitting (so-called press-fit), as this risks immediate cracking of this professional component. To ensure stability 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 90% of applications in modeling and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø25x2.5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

This model is characterized by dimensions Ø25x2.5 mm, which, at a weight of 9.2 g, makes it an element with impressive magnetic energy density. The value of 25.03 N means that the magnet is capable of holding a weight many times exceeding its own mass of 9.2 g. The product has a [NiCuNi] coating, which secures it against external factors, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 2.5 mm), which means that the N and S poles are located on the flat, circular surfaces. 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 immense strength, neodymium magnets offer the following advantages:

They have constant strength, and over more than ten years their performance decreases symbolically – ~1% (according to theory),
They have excellent resistance to weakening of magnetic properties as a result of external fields,
The use of an elegant finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
They are known for high magnetic induction at the operating surface, which affects their effectiveness,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
Due to the possibility of free forming and adaptation to custom solutions, neodymium magnets can be produced in a variety of shapes and sizes, which expands the range of possible applications,
Versatile presence in electronics industry – they find application in hard drives, electric drive systems, medical devices, also industrial machines.
Thanks to concentrated force, small magnets offer high operating force, in miniature format,

Cons

Problematic aspects of neodymium magnets: weaknesses and usage proposals

They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (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 very resistant to heat
They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Due to limitations in producing nuts and complicated forms in magnets, we propose using cover - magnetic holder.
Potential hazard to health – tiny shards of magnets are risky, in case of ingestion, which becomes key in the context of child health protection. It is also worth noting that small components of these devices are able to complicate diagnosis medical after entering the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Pull force analysis

Maximum magnetic pulling force – what contributes to it?

The declared magnet strength represents the maximum value, measured under optimal environment, meaning:

using a sheet made of high-permeability steel, acting as a ideal flux conductor
with a thickness of at least 10 mm
characterized by smoothness
with direct contact (no paint)
during detachment in a direction vertical to the mounting surface
at conditions approx. 20°C

Key elements affecting lifting force

In practice, the actual lifting capacity results from several key aspects, presented from the most important:

Distance – the presence of foreign body (rust, tape, air) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
Plate material – mild steel gives the best results. Alloy steels decrease magnetic permeability and lifting capacity.
Surface finish – full contact is obtained only on smooth steel. Rough texture create air cushions, weakening the magnet.
Thermal environment – temperature increase causes a temporary drop of induction. Check the thermal limit for a given model.

Lifting capacity was assessed with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under shearing force the holding force is lower. In addition, even a slight gap between the magnet and the plate lowers the lifting capacity.

Precautions when working with neodymium magnets

Flammability

Drilling and cutting of neodymium magnets poses a fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.

Shattering risk

Despite the nickel coating, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.

Heat sensitivity

Keep cool. NdFeB magnets are sensitive to heat. If you need operation above 80°C, ask us about special high-temperature series (H, SH, UH).

Physical harm

Large magnets can crush fingers in a fraction of a second. Under no circumstances place your hand betwixt two attracting surfaces.

Handling guide

Handle magnets consciously. Their powerful strength can surprise even professionals. Be vigilant and do not underestimate their power.

Magnetic interference

Remember: neodymium magnets generate a field that disrupts sensitive sensors. Keep a separation from your mobile, device, and GPS.

Threat to electronics

Avoid bringing magnets close to a purse, computer, or TV. The magnetic field can irreversibly ruin these devices and erase data from cards.

Danger to pacemakers

Individuals with a pacemaker should keep an large gap from magnets. The magnetic field can stop the operation of the life-saving device.

Avoid contact if allergic

Nickel alert: The nickel-copper-nickel coating contains nickel. If skin irritation occurs, immediately stop handling magnets and use protective gear.

Swallowing risk

Product intended for adults. Small elements pose a choking risk, causing serious injuries. Store away from children and animals.
