Grip strength decreases significantly with every mm of gap. Keep in mind that every additional insulation layer (e.g., contamination, varnish, rust) noticeably reduces the pull force. Magnets hold optimally in perfect adhesion; air break kills the power. See how quickly the parameters drop, when the magnet does not adhere tightly to the metal substrate. When planning the mounting, eliminate additional spacers.

Table 2: Shear force (vertical surface)

This section presents the approximate shear load required to start the shifting of the magnet down on a upright steel plate (considering typical friction). This value is a function of the air gap between the magnet and the surface.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MW 2x4 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.03 kg / 0.06 lbs 27.0 g / 0.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.02 kg / 0.04 lbs 18.0 g / 0.2 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.01 kg / 0.02 lbs 9.0 g / 0.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.05 kg / 0.10 lbs 45.0 g / 0.4 N

When placing a element on a vertical plane (e.g., a fridge), it will only hold barely approx. 1/5 of its nominal power. Gravity as well as a low friction coefficient influence the fact that products slip easier than they pull off. Designing a hanger? Remember that the sliding force is much weaker than the perpendicular breakaway force. On a painted metal, the magnet will give way down under a significantly smaller weight. Using a rubber coating can significantly increase the grip.

Table 4: Material efficiency (saturation) - power losses
MW 2x4 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	10%	0.01 kg / 0.02 lbs 9.0 g / 0.1 N
1 mm	25%	0.02 kg / 0.05 lbs 22.5 g / 0.2 N
2 mm	50%	0.05 kg / 0.10 lbs 45.0 g / 0.4 N
3 mm	75%	0.07 kg / 0.15 lbs 67.5 g / 0.7 N
5 mm	100%	0.09 kg / 0.20 lbs 90.0 g / 0.9 N
10 mm	100%	0.09 kg / 0.20 lbs 90.0 g / 0.9 N
11 mm	100%	0.09 kg / 0.20 lbs 90.0 g / 0.9 N
12 mm	100%	0.09 kg / 0.20 lbs 90.0 g / 0.9 N

A too thin steel is not enough to conduct the entire magnetic field, which weakens actual performance of the magnet. Should you mount a strong magnet to a too thin substrate, the field will penetrate right through and the holding will be smaller. To squeeze 100% of this neodymium's potential, you need a suitably thick element of steel. The saturation phenomenon means that on delicate walls (e.g., thin profiles), the holder holds weaker. We suggest choosing the steel cross-section according to the table below.

Table 5: Thermal stability (material behavior) - resistance threshold
MW 2x4 / N38

Ambient temp. (°C)	Power loss	Remaining pull (kg/lbs/g/N)	Status
20 °C	0.0%	0.09 kg / 0.20 lbs 90.0 g / 0.9 N	OK
40 °C	-2.2%	0.09 kg / 0.19 lbs 88.0 g / 0.9 N	OK
60 °C	-4.4%	0.09 kg / 0.19 lbs 86.0 g / 0.8 N	OK
80 °C	-6.6%	0.08 kg / 0.19 lbs 84.1 g / 0.8 N
100 °C	-28.8%	0.06 kg / 0.14 lbs 64.1 g / 0.6 N

Classic neodymiums lose parameters past the thermal threshold. Watch out for overheating – heat can irreversibly damage this product. With every degree above norm, the neodymium's force momentarily lowers. Avoid using this magnet close to heaters exceeding its working range. Exceeding the critical threshold will lead to permanent loss of magnetic properties.

*Important note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Flat magnets (pancake types) risk losing magnetic properties at lower temperatures than taller cylinders. The danger warning in the table indicates permanent field degradation for this particular item.

Two magnetic products interact from a significantly greater distance than a neodymium and metal setup. Such a system of two magnets generates a stronger field and a wider radius of action. Planning to create a strong closure? Utilize two neodymiums instead of a neodymium and a striker plate. Be careful that when connecting a pair of magnets, the impact force is extreme. The levitation is marginally weaker than the attraction, but still impressive.
*Field value for N-N configuration reaches ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
Important: Estimates show sliding force of two matching magnets (friction coefficient ~0.15 for Ni-Ni plating).

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

A strong magnetic field is a serious hazard to IT equipment as well as pacemakers. These magnets generate a field that prevents correct functioning of digital equipment. Remember: the invisible magnetic field passes through tissues and glass. Exceptional care must be exercised by people with hearing aids and insulin pumps. Also at risk are: automatic timepieces, car keys, speakers, and screens. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Neodymium magnets are prone to chipping – a violent impact against metal can result in shattering. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Impact energy can trigger coating fragments or painful pinches to fingers. Be sure to control the product during bringing near metal so it doesn't hit with great force against the metal. A collision at high speed ends with a crack of the magnet. Use safety goggles when working with large magnets.

Environment	Effective steel pull	Effect
Air (land)	0.09 kg	Standard
Water (riverbed)	0.10 kg (+0.01 kg buoyancy gain)	+14.5%

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

Contrary to myths, water does not block the magnetic field. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Sliding resistance

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

2. Efficiency vs thickness

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

3. Power loss vs temp

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.21

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, made from modern NdFeB material, which, at dimensions of Ø2x4 mm, guarantees optimal power. The MW 2x4 / N38 component is characterized by an accuracy of ±0.1mm and professional build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 0.09 kg), this product is available off-the-shelf from our European logistics center, ensuring lightning-fast order fulfillment. Additionally, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is ideal for building electric motors, advanced sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the pull force of 0.86 N with a weight of only 0.09 g, this rod is indispensable in electronics and wherever every gram matters.

Due to the delicate structure of the ceramic sinter, you must not use force-fitting (so-called press-fit), as this risks immediate cracking of this precision component. To ensure stability in industry, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Magnets N38 are suitable for the majority of applications in automation and machine building, where excessive miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø2x4), 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 Ø2x4 mm, which, at a weight of 0.09 g, makes it an element with high magnetic energy density. The value of 0.86 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.09 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 4 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 as well as cons of neodymium magnets.

Benefits

In addition to their magnetic efficiency, neodymium magnets provide the following advantages:

They do not lose strength, even over approximately ten years – the reduction in power is only ~1% (theoretically),
They possess excellent resistance to magnetic field loss due to external fields,
In other words, due to the shiny surface of silver, the element looks attractive,
Neodymium magnets generate maximum magnetic induction on a small surface, which increases force concentration,
Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
Possibility of custom machining as well as adjusting to precise conditions,
Wide application in modern technologies – they are utilized in HDD drives, motor assemblies, advanced medical instruments, as well as industrial machines.
Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in compact constructions

Cons

Disadvantages of neodymium magnets:

Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a special holder, which not only secures them against impacts but also raises their durability
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
Due to limitations in producing threads and complicated forms in magnets, we recommend using a housing - magnetic mount.
Potential hazard to health – tiny shards of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. Furthermore, small elements of these devices are able to be problematic in diagnostics medical after entering 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

Magnetic strength at its maximum – what contributes to it?

Breakaway force was determined for the most favorable conditions, including:

using a plate made of low-carbon steel, functioning as a ideal flux conductor
whose transverse dimension equals approx. 10 mm
with an ideally smooth contact surface
with direct contact (without coatings)
under axial force direction (90-degree angle)
at ambient temperature room level

Lifting capacity in practice – influencing factors

In real-world applications, the actual lifting capacity results from many variables, listed from most significant:

Distance – existence of foreign body (paint, dirt, gap) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of nominal force).
Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
Material composition – different alloys attracts identically. Alloy additives weaken the interaction with the magnet.
Surface structure – the more even the plate, the better the adhesion and stronger the hold. Unevenness creates an air distance.
Temperature influence – hot environment reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.

Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate decreases the load capacity.

Warnings

Finger safety

Risk of injury: The pulling power is so great that it can result in blood blisters, pinching, and broken bones. Protective gloves are recommended.

Combustion hazard

Dust produced during machining of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.

Powerful field

Handle with care. Rare earth magnets act from a long distance and snap with huge force, often quicker than you can react.

Electronic hazard

Do not bring magnets close to a purse, computer, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.

Keep away from electronics

Note: rare earth magnets generate a field that disrupts precision electronics. Maintain a safe distance from your phone, tablet, and GPS.

Magnets are brittle

Despite metallic appearance, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.

Operating temperature

Avoid heat. NdFeB magnets are sensitive to temperature. If you need resistance above 80°C, inquire about special high-temperature series (H, SH, UH).

Warning for allergy sufferers

Nickel alert: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction happens, cease handling magnets and wear gloves.

No play value

Strictly store magnets away from children. Risk of swallowing is significant, and the effects of magnets connecting inside the body are tragic.

Pacemakers

Patients with a ICD have to keep an large gap from magnets. The magnetism can disrupt the functioning of the life-saving device.
