Pulling power drops sharply with every mm of distance. Note that even a microscopic distance (e.g., dirt, paint, dust) noticeably diminishes the holding power. Neodymiums work strongest in perfect adhesion; distance weakens the force. See how quickly the load capacity drop, when the product does not adhere flatly to the steel surface. When planning the arrangement, avoid redundant distances.

The table below calculates the estimated shear load required to cause the sliding of the magnet vertically on a vertical steel wall (considering typical friction coefficient). This parameter varies with the separation distance between the magnet and the surface.

Table 3: Wall mounting (shearing) - vertical pull
MW 15x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.45 kg / 1.00 lbs 453.0 g / 4.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.30 kg / 0.67 lbs 302.0 g / 3.0 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.15 kg / 0.33 lbs 151.0 g / 1.5 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.76 kg / 1.66 lbs 755.0 g / 7.4 N

When mounting a element on a upright wall (e.g., a car body), it will maintain barely about 1/5 of its nominal power. Gravitational force and a weak degree of grip influence the fact that products slide down easier than they pull off. Planning a hanger? Consider that the sliding force is significantly lower than the maximum static pull force. On a slippery surface, the magnet will slide down under a noticeably lighter weight. Using a rubber layer can drastically improve the result.

A thin metal plate cannot absorb the full magnetic flux, which weakens actual performance of the holder. Should you install a neodymium to a thin surface, the magnetism will penetrate right through and the holding will be smaller. To achieve 100% of this magnet's potential, you need a suitably thick backing of metal. The material oversaturation causes that on delicate walls (e.g., appliance housings), the holder shows lower pull force. We suggest choosing the steel thickness based on the following data.

100 °C	-28.8%	1.08 kg / 2.37 lbs 1075.1 g / 10.5 N

Classic neodymiums lose parameters after exceeding the maximum temperature. Watch out for overheating – heat can permanently damage this magnet. With increasing heat, the magnet's force temporarily lowers. Do not use this product close to ovens higher than its safe range. Too high temperature will result in permanent loss of magnetic properties.

*Engineering note: Heat tolerance is determined by both grade, as well as the dimension ratios. Low-profile magnets (low Pc) risk losing magnetic properties under lower heat stress than taller cylinders. The danger warning in the table points to permanent field degradation for this particular item.

Two magnets interact from a much further distance than a magnet and sheet setup. The setup of magnet-to-magnet produces a massive flux and a larger range of action. Want to build a powerful holder? Use a pair of magnets instead of a neodymium and a striker plate. Be careful that when attracting two neodymiums, the pinch force is extreme. The repulsion force is slightly lower than the connection force, but still large.
*Field value in repulsion mode drops to ~0 Gs at the geometric center of the gap (resulting from vector opposition).
* Results demonstrate friction force of dual identical neodymium magnets (friction ~0.15 for Ni-Ni layer).

Table 7: Safety (HSE) (implants) - precautionary measures
MW 15x2 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	5.5 cm
Hearing aid	10 Gs (1.0 mT)	4.0 cm
Mechanical watch	20 Gs (2.0 mT)	3.5 cm
Mobile device	40 Gs (4.0 mT)	2.5 cm
Car key	50 Gs (5.0 mT)	2.5 cm
Payment card	400 Gs (40.0 mT)	1.0 cm
HDD hard drive	600 Gs (60.0 mT)	1.0 cm

A strong magnetic field is a serious hazard to electronics as well as pacemakers. These magnets produce a flux that prevents correct functioning of sensitive medical devices. Be aware: the invisible magnetic field passes through tissues and glass. Special caution must be exercised by people with hearing aids and drug dispensers. Also at risk are: mechanical watches, remotes, speakers, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Table 8: Collisions (kinetic energy) - collision effects
MW 15x2 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	24.59 km/h (6.83 m/s)	0.06 J
30 mm	41.70 km/h (11.58 m/s)	0.18 J
50 mm	53.83 km/h (14.95 m/s)	0.30 J
100 mm	76.13 km/h (21.15 m/s)	0.59 J

Magnetic elements are very brittle – a collision with steel risks their cracking. Pay attention to connection velocity – a magnet released freely speeds with massive force. Kinetic force can trigger coating fragments or painful pinches to fingers. Be sure to control the product during installation so it doesn't slam with momentum against the steel surface. A collision at high speed means shattering of the neodymium. Use safety goggles when playing with powerful specimens.

Water (riverbed)	1.73 kg (+0.22 kg buoyancy gain)	+14.5%

Rust risk: 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. Shear force

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

2. Steel thickness impact

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

3. Thermal stability

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.20

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 offered product is an extremely powerful rod magnet, composed of modern NdFeB material, which, at dimensions of Ø15x2 mm, guarantees maximum efficiency. The MW 15x2 / N38 component boasts high dimensional repeatability and industrial build quality, making it an excellent solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 1.51 kg), this product is available off-the-shelf from our European logistics center, ensuring quick order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is perfect for building electric motors, advanced Hall effect sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the high power of 14.84 N with a weight of only 2.65 g, this rod is indispensable in electronics and wherever low weight is crucial.

Due to the brittleness of the NdFeB material, you must not use force-fitting (so-called press-fit), as this risks immediate cracking of this precision component. 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 the strongest magnets in the same volume (Ø15x2), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

This model is characterized by dimensions Ø15x2 mm, which, at a weight of 2.65 g, makes it an element with high magnetic energy density. The value of 14.84 N means that the magnet is capable of holding a weight many times exceeding its own mass of 2.65 g. The product has a [NiCuNi] coating, which secures it against oxidation, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 2 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.

Pros and cons of rare earth magnets.

Benefits

Apart from their consistent magnetism, neodymium magnets have these key benefits:

They retain attractive force for around 10 years – the loss is just ~1% (based on simulations),
They are extremely resistant to demagnetization induced by presence of other magnetic fields,
In other words, due to the shiny layer of gold, the element looks attractive,
They show high magnetic induction at the operating surface, which increases their power,
Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures approaching 230°C and above...
Possibility of precise shaping and adapting to individual requirements,
Huge importance in high-tech industry – they serve a role in mass storage devices, drive modules, precision medical tools, and complex engineering applications.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which allows their use in small systems

Weaknesses

What to avoid - cons of neodymium magnets: tips and applications.

They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects 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
Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
Limited possibility of making nuts in the magnet and complex shapes - recommended is cover - magnet mounting.
Possible danger related to microscopic parts of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child health protection. Additionally, tiny parts of these magnets are able to be problematic in diagnostics medical in case of swallowing.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Holding force characteristics

Maximum lifting force for a neodymium magnet – what affects it?

The force parameter is a theoretical maximum value conducted under specific, ideal conditions:

with the contact of a sheet made of special test steel, guaranteeing full magnetic saturation
with a cross-section minimum 10 mm
with a plane free of scratches
under conditions of no distance (metal-to-metal)
for force acting at a right angle (in the magnet axis)
at conditions approx. 20°C

Practical aspects of lifting capacity – factors

Bear in mind that the application force may be lower depending on the following factors, in order of importance:

Distance (between the magnet and the plate), as even a very small clearance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to paint, corrosion or debris).
Force direction – catalog parameter refers to detachment vertically. When slipping, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
Metal type – not every steel reacts the same. High carbon content worsen the interaction with the magnet.
Surface condition – ground elements guarantee perfect abutment, which improves force. Rough surfaces reduce efficiency.
Thermal factor – high temperature weakens magnetic field. Too high temperature can permanently damage the magnet.

Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under shearing force the holding force is lower. In addition, even a slight gap between the magnet and the plate reduces the holding force.

Precautions when working with neodymium magnets

ICD Warning

Health Alert: Strong magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.

GPS and phone interference

Navigation devices and mobile phones are highly sensitive to magnetic fields. Close proximity with a strong magnet can permanently damage the internal compass in your phone.

Demagnetization risk

Regular neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. Damage is permanent.

Cards and drives

Intense magnetic fields can destroy records on credit cards, hard drives, and other magnetic media. Maintain a gap of at least 10 cm.

Magnets are brittle

Despite the nickel coating, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.

Do not drill into magnets

Mechanical processing of neodymium magnets poses a fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.

Serious injuries

Watch your fingers. Two powerful magnets will snap together immediately with a force of massive weight, destroying anything in their path. Exercise extreme caution!

Avoid contact if allergic

Certain individuals have a sensitization to nickel, which is the standard coating for neodymium magnets. Extended handling may cause a rash. We strongly advise use safety gloves.

Keep away from children

Only for adults. Tiny parts pose a choking risk, leading to severe trauma. Keep out of reach of children and animals.

Handling guide

Use magnets consciously. Their powerful strength can surprise even experienced users. Be vigilant and do not underestimate their power.
