Magnetic force decreases significantly per each millimeter of distance. Keep in mind that even the smallest gap (e.g., contamination, varnish, rust) strongly reduces the pull force. Magnetic products work strongest during direct contact; gap nullifies the power. See how quickly the load capacity plummet, when the product does not adhere tightly to the metal substrate. When planning the assembly, avoid additional spacers.

The following data presents the estimated shear load needed to start the downward movement of the magnet vertically against a vertical steel plate (considering standard friction). This value is relative to the distance between the magnet and the surface.

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

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.09 kg / 0.20 lbs 90.0 g / 0.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.06 kg / 0.13 lbs 60.0 g / 0.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.03 kg / 0.07 lbs 30.0 g / 0.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.15 kg / 0.33 lbs 150.0 g / 1.5 N

When placing a element on a upright plane (e.g., a car body), it will maintain barely approx. 1/5 of nominal attraction strength. Gravity and a weak degree of grip mean that holders slip easier than they detach. Want to create a wall mount? Note that the sliding force is much weaker than the perpendicular breakaway force. On a smooth steel, the element will slide down under a significantly smaller weight. Using a rubber pad can drastically improve the result.

Table 4: Steel thickness (saturation) - sheet metal selection
MW 3x2 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	10%	0.03 kg / 0.07 lbs 30.0 g / 0.3 N
1 mm	25%	0.08 kg / 0.17 lbs 75.0 g / 0.7 N
2 mm	50%	0.15 kg / 0.33 lbs 150.0 g / 1.5 N
3 mm	75%	0.22 kg / 0.50 lbs 225.0 g / 2.2 N
5 mm	100%	0.30 kg / 0.66 lbs 300.0 g / 2.9 N
10 mm	100%	0.30 kg / 0.66 lbs 300.0 g / 2.9 N
11 mm	100%	0.30 kg / 0.66 lbs 300.0 g / 2.9 N
12 mm	100%	0.30 kg / 0.66 lbs 300.0 g / 2.9 N

A too thin steel cannot absorb the full magnetic flux, which wastes potential of the magnet. Should you mount a strong magnet to a weak sheet, the field will penetrate right through and the pull force will drop sharply. To utilize full efficiency of this magnet's potential, you need a suitably thick piece of steel. The saturation phenomenon causes that on delicate walls (e.g., appliance housings), the holder holds weaker. We advise picking the steel cross-section based on the following data.

Table 5: Thermal resistance (stability) - resistance threshold
MW 3x2 / N38

Ambient temp. (°C)	Power loss	Remaining pull (kg/lbs/g/N)	Status
20 °C	0.0%	0.30 kg / 0.66 lbs 300.0 g / 2.9 N	OK
40 °C	-2.2%	0.29 kg / 0.65 lbs 293.4 g / 2.9 N	OK
60 °C	-4.4%	0.29 kg / 0.63 lbs 286.8 g / 2.8 N	OK
80 °C	-6.6%	0.28 kg / 0.62 lbs 280.2 g / 2.7 N
100 °C	-28.8%	0.21 kg / 0.47 lbs 213.6 g / 2.1 N

Ordinary NdFeB products change their properties power past the thermal threshold. Protect against heat – heat can irreversibly destroy this product. With increasing heat, the neodymium's power temporarily drops. Do not use this magnet near heat sources exceeding its working range. Exceeding the critical threshold will result in destruction of magnetic properties.

*Important note: Temperature resistance is determined by both grade, as well as the dimension ratios. Flat magnets (low Pc) are more susceptible to demagnetization sooner than taller cylinders. Warning indicator in the table signals permanent field degradation for this specific geometry.

Two magnets interact from a much further distance than a magnet and steel setup. Such a system of magnet-to-magnet produces a massive flux and a larger range of performance. Designing a powerful holder? Utilize two neodymiums instead of one magnet and a steel. Remember that when bringing together two magnets, the impact force is extreme. The repulsion force is slightly lower than the connection force, but still significant.
*Field value in repulsion mode reaches ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
Attention: Calculations show friction force of dual identical magnets (friction coefficient ~0.15 for Ni-Ni plating).

Table 7: Protective zones (implants) - precautionary measures
MW 3x2 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	2.0 cm
Hearing aid	10 Gs (1.0 mT)	1.5 cm

A strong magnetic field is a serious hazard to electronics and pacemakers. These magnets produce a flux that prevents correct functioning of sensitive medical devices. Be aware: the invisible magnetic field penetrates the body and housings. Increased vigilance must be exercised by people with cochlear implants and drug dispensers. The risk also applies to: automatic timepieces, remotes, speakers, and screens. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Table 8: Dynamics (cracking risk) - collision effects
MW 3x2 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	52.67 km/h (14.63 m/s)	0.01 J
30 mm	91.22 km/h (25.34 m/s)	0.04 J

100 mm	166.55 km/h (46.26 m/s)	0.12 J

Magnetic elements are very brittle – a strong collision with metal risks their cracking. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Kinetic force can trigger coating fragments or injury to fingers. Always hold the magnet during mounting so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h means shattering of the magnet. Use safety goggles when playing with powerful specimens.

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

In water, the magnet feels stronger thanks to Archimedes' principle. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Wall mount (shear)

*Warning: On a vertical wall, the magnet holds merely a fraction of its max power.

2. Steel saturation

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

3. Power loss vs temp

*For N38 grade, 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) = 0.71

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 cylinder magnet, composed of advanced NdFeB material, which, at dimensions of Ø3x2 mm, guarantees the highest energy density. This specific item boasts high dimensional repeatability and industrial build quality, making it a perfect solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 0.30 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Additionally, its Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is created for building generators, advanced Hall effect sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the high power of 2.99 N with a weight of only 0.11 g, this rod is indispensable in miniature devices and wherever every gram matters.

Due to the delicate structure of the ceramic sinter, we absolutely advise against force-fitting (so-called press-fit), as this risks chipping the coating of this professional component. To ensure stability in industry, anaerobic resins 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 the majority of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø3x2), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

This model is characterized by dimensions Ø3x2 mm, which, at a weight of 0.11 g, makes it an element with impressive magnetic energy density. The value of 2.99 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.11 g. The product has a [NiCuNi] coating, which protects the surface 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. 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.

Strengths as well as weaknesses of Nd₂Fe₁₄B magnets.

Pros

Besides their magnetic performance, neodymium magnets are valued for these benefits:

They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
They maintain their magnetic properties even under strong external field,
A magnet with a shiny gold surface has better aesthetics,
Magnetic induction on the working part of the magnet remains strong,
Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
Possibility of precise modeling and adapting to individual conditions,
Fundamental importance in modern technologies – they serve a role in HDD drives, electric motors, advanced medical instruments, and technologically advanced constructions.
Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which enables their usage in small systems

Limitations

Cons of neodymium magnets and proposals for their use:

To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
Due to limitations in producing threads and complex forms in magnets, we propose using cover - magnetic mount.
Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the context of child health protection. Furthermore, small elements of these products can disrupt the diagnostic process medical in case of swallowing.
Due to expensive raw materials, their price exceeds standard values,

Pull force analysis

Maximum holding power of the magnet – what it depends on?

The lifting capacity listed is a measurement result executed under specific, ideal conditions:

on a base made of mild steel, perfectly concentrating the magnetic flux
with a cross-section no less than 10 mm
with a surface cleaned and smooth
without the slightest insulating layer between the magnet and steel
for force acting at a right angle (in the magnet axis)
in stable room temperature

Key elements affecting lifting force

In real-world applications, the actual lifting capacity is determined by several key aspects, presented from most significant:

Distance – the presence of foreign body (rust, tape, gap) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
Metal type – different alloys reacts the same. Alloy additives weaken the interaction with the magnet.
Surface finish – ideal contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
Thermal environment – temperature increase results in weakening of induction. Check the thermal limit for a given model.

Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under shearing force the holding force is lower. Moreover, even a minimal clearance between the magnet and the plate lowers the lifting capacity.

Precautions when working with NdFeB magnets

Keep away from computers

Do not bring magnets close to a purse, computer, or screen. The magnetic field can permanently damage these devices and erase data from cards.

Avoid contact if allergic

Certain individuals have a sensitization to nickel, which is the standard coating for neodymium magnets. Frequent touching can result in skin redness. We suggest use protective gloves.

Crushing force

Protect your hands. Two large magnets will snap together immediately with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!

Keep away from electronics

GPS units and smartphones are highly susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the sensors in your phone.

No play value

Strictly store magnets away from children. Risk of swallowing is high, and the effects of magnets connecting inside the body are very dangerous.

Magnets are brittle

Neodymium magnets are ceramic materials, meaning they are very brittle. Collision of two magnets will cause them shattering into shards.

Mechanical processing

Drilling and cutting of NdFeB material carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Safe operation

Before use, check safety instructions. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.

Power loss in heat

Keep cool. NdFeB magnets are susceptible to temperature. If you need operation above 80°C, inquire about HT versions (H, SH, UH).

Pacemakers

For implant holders: Powerful magnets disrupt electronics. Maintain at least 30 cm distance or request help to handle the magnets.
