Pulling power decreases significantly with every subsequent millimeter of gap. Note that even the smallest gap (e.g., dirt, varnish, dust) strongly reduces the pull force. Neodymiums operate optimally in perfect adhesion; air break kills the power. Notice how rapidly the pull force plummet, when the product does not touch tightly to the metal substrate. When planning the arrangement, eliminate additional spacers.

The table below indicates the approximate weight limit necessary to start the downward movement of the magnet downwards against a upright steel plate (considering typical friction coefficient). This value is a function of the air gap between the magnet and the surface.

Table 3: Wall mounting (shearing) - vertical pull
MW 6x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.26 kg / 0.57 LBS 258.0 g / 2.5 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.17 kg / 0.38 LBS 172.0 g / 1.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.09 kg / 0.19 LBS 86.0 g / 0.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.43 kg / 0.95 LBS 430.0 g / 4.2 N

When placing a holder on a vertical surface (e.g., a fridge), it will only hold barely approx. 20%-30% of its maximum pull force. Gravity as well as a low friction coefficient mean that magnets move down faster than they detach. Planning a wall mount? Consider that the shear force is noticeably lower than the maximum static pull force. On a smooth steel, the magnet will slide down under a much lighter load. Application of an anti-slip layer can drastically raise the stability.

12 mm	100%	0.86 kg / 1.90 LBS 860.0 g / 8.4 N

A too thin steel cannot focus the entire magnetic field, which wastes potential of the holder. If you mount a strong magnet to a too thin substrate, the flux will pass right through and the pull force will drop sharply. To utilize 100% of this neodymium's power, you require a sufficiently solid element of steel. The saturation effect means that on thin elements (e.g., thin profiles), the product holds weaker. We advise picking the steel cross-section from these parameters.

Standard neodymium magnets lose power above the temperature limit. Avoid high temperatures – high temperature can irreversibly damage this product. With every degree above norm, the neodymium's power briefly decreases. Refrain from using this magnet near heat sources higher than its operating temperature limit. Ignoring the limit will cause permanent loss of magnetic properties.

*Technical advisory: Temperature resistance is determined by both grade, and the Permeance Coefficient Pc. Low-profile magnets (pancake types) are more susceptible to demagnetization at lower temperatures than taller cylinders. The danger warning in the table points to a risk of irreversible loss for this specific geometry.

Two magnetic products interact from a significantly greater distance than a magnet and sheet setup. The setup of two magnets produces a massive flux and a larger range of operation. Want to build a solid fastener? Apply two magnets instead of a neodymium and a striker plate. Exercise caution that when connecting a pair of magnets, the pinch force is massive. The repulsion force is a bit weaker than the attraction, but still large.
*Field value in repulsion mode is approximately ~0 Gs at the midpoint of the gap (resulting from vector opposition).
* Calculations apply to friction force of a pair of same magnets (friction coefficient ~0.15 for Ni-Ni coating).

Extremely neodym field poses a serious hazard to electronics and pacemakers. These magnets generate a field that disrupts operation of digital equipment. Be aware: the invisible magnetic field acts through matter and plastic. Exceptional care must be exercised by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, remotes, speakers, and screens. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Table 8: Impact energy (cracking risk) - collision effects
MW 6x2 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	45.65 km/h (12.68 m/s)	0.03 J
30 mm	79.04 km/h (21.96 m/s)	0.10 J
50 mm	102.04 km/h (28.35 m/s)	0.17 J
100 mm	144.31 km/h (40.09 m/s)	0.34 J

NdFeB products are prone to chipping – a collision with steel can result in shattering. Watch the impact speed – a magnet released freely speeds with massive force. Kinetic force can destroy the magnet or dangerous crushing to skin. Always hold the magnet during bringing near metal so it doesn't hit violently against the steel surface. A collision at high speed almost guarantees destruction of the magnet. Use safety goggles when working 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!

Water displaces steel, making heavy objects slightly lighter. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Sliding resistance

*Warning: On a vertical surface, the magnet retains just ~20% of its nominal pull.

2. Efficiency vs thickness

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

3. Temperature resistance

*For standard magnets, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.44

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 modern NdFeB material, which, at dimensions of Ø6x2 mm, guarantees maximum efficiency. This specific item is characterized by a tolerance of ±0.1mm and professional build quality, making it an excellent solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 0.86 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring rapid order fulfillment. Additionally, its Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

It successfully proves itself in modeling, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 8.43 N with a weight of only 0.42 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 chipping the coating of this professional component. To ensure long-term durability in automation, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Magnets NdFeB grade N38 are strong enough for 90% 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 (Ø6x2), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 6 mm and height 2 mm. The value of 8.43 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.42 g. The product has a [NiCuNi] coating, which protects the surface against external factors, 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 6 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 as well as cons of Nd₂Fe₁₄B magnets.

Benefits

Besides their immense magnetic power, neodymium magnets offer the following advantages:

They do not lose power, even after around ten years – the reduction in strength is only ~1% (based on measurements),
Neodymium magnets remain highly resistant to magnetic field loss caused by external field sources,
The use of an refined finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
Neodymium magnets deliver maximum magnetic induction on a small area, which increases force concentration,
Neodymium magnets are characterized by very 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...
Thanks to flexibility in shaping and the capacity to adapt to specific needs,
Huge importance in modern industrial fields – they are commonly used in mass storage devices, electric motors, precision medical tools, also modern systems.
Thanks to their power density, small magnets offer high operating force, in miniature format,

Limitations

Disadvantages of neodymium magnets:

To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their strength 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
When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
We recommend casing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complex forms.
Health risk to health – tiny shards of magnets pose a threat, in case of ingestion, which becomes key in the context of child safety. It is also worth noting that tiny parts of these products can be problematic in diagnostics medical when they are in the body.
With budget limitations the cost of neodymium magnets is economically unviable,

Holding force characteristics

Maximum lifting capacity of the magnet – what it depends on?

Breakaway force was defined for the most favorable conditions, taking into account:

using a base made of mild steel, functioning as a magnetic yoke
with a cross-section of at least 10 mm
with an ideally smooth touching surface
under conditions of ideal adhesion (metal-to-metal)
during detachment in a direction vertical to the mounting surface
in temp. approx. 20°C

Lifting capacity in real conditions – factors

Please note that the working load may be lower subject to the following factors, starting with the most relevant:

Clearance – the presence of any layer (paint, tape, air) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of generating force.
Metal type – not every steel reacts the same. High carbon content weaken the interaction with the magnet.
Plate texture – ground elements ensure maximum contact, which increases force. Rough surfaces reduce efficiency.
Temperature – heating the magnet causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity was assessed with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, whereas under attempts to slide the magnet the holding force is lower. Moreover, even a slight gap between the magnet and the plate reduces the holding force.

Safety rules for work with neodymium magnets

Flammability

Fire warning: Rare earth powder is highly flammable. Do not process magnets without safety gear as this risks ignition.

Life threat

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

Threat to navigation

Note: rare earth magnets produce a field that confuses sensitive sensors. Keep a safe distance from your mobile, tablet, and navigation systems.

Electronic devices

Do not bring magnets near a purse, computer, or screen. The magnetic field can irreversibly ruin these devices and erase data from cards.

Conscious usage

Exercise caution. Neodymium magnets attract from a long distance and connect with massive power, often faster than you can react.

Hand protection

Big blocks can smash fingers in a fraction of a second. Under no circumstances place your hand between two attracting surfaces.

Risk of cracking

Beware of splinters. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.

Do not give to children

Only for adults. Tiny parts pose a choking risk, causing serious injuries. Store away from kids and pets.

Sensitization to coating

Nickel alert: The Ni-Cu-Ni coating contains nickel. If an allergic reaction occurs, immediately stop working with magnets and use protective gear.

Do not overheat magnets

Standard neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. This process is irreversible.

Caution! Details about hazards in the article: Safety of working with magnets.
