Grip strength weakens drastically with every subsequent millimeter of distance. Keep in mind that even the smallest gap (e.g., dirt, paint, rust) noticeably reduces the pull force. Neodymiums work strongest during direct contact; gap drastically cuts the force. Notice how quickly the parameters drop, when the magnet does not adhere flatly to the steel surface. When calculating the assembly, discard redundant distances.

This section defines the theoretical force needed to cause the shifting of the magnet vertically on a upright metal surface (considering standard friction). This parameter varies with the separation distance between the magnet and the surface.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MW 8x8 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.61 kg / 1.34 pounds 609.0 g / 6.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.41 kg / 0.90 pounds 406.0 g / 4.0 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.20 kg / 0.45 pounds 203.0 g / 2.0 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.02 kg / 2.24 pounds 1015.0 g / 10.0 N

When hanging a element on a upright wall (e.g., a car body), it you can count on just approx. 1/5 of its nominal power. Gravity as well as a weak degree of grip influence the fact that holders slide down easier than they detach. Want to create a wall mount? Note that the shear force is significantly lower than the maximum static pull force. On a slippery surface, the magnet will slide down under a significantly smaller cargo. Utilizing a rubberized pad can drastically raise the stability.

12 mm	100%	2.03 kg / 4.48 pounds 2030.0 g / 19.9 N

A thin metal plate is unable to take in the full magnetic flux, which squanders power of the magnet. If you install a neodymium to a too thin substrate, the magnetism will penetrate right through and the holding will be smaller. To utilize full efficiency of this magnet's power, you need a suitably thick backing of steel. The material oversaturation causes that on delicate walls (e.g., appliance housings), the product holds weaker. We suggest choosing the steel cross-section according to the table below.

Table 5: Thermal resistance (material behavior) - resistance threshold
MW 8x8 / N38

Ambient temp. (°C)	Power loss	Remaining pull (kg/lbs/g/N)	Status

Standard neodymium magnets change their properties power above the temperature limit. Protect against heat – excessive heat can permanently destroy this product. As the temperature rises, the magnet's capacity momentarily decreases. Do not use this magnet close to ovens higher than its working range. Ignoring the limit will lead to destruction of magnetic properties.

*Engineering note: Heat tolerance is determined by both grade, and the Permeance Coefficient Pc. Low-profile magnets (low permeance coefficient) risk losing magnetic properties at lower temperatures than taller cylinders. Red status in the table signals permanent field degradation for this particular item.

Two magnetic products attract each other from a much further distance than a neodymium and metal combination. The setup of two magnets produces a massive flux and a further horizon of operation. Planning to create a solid fastener? Apply two magnets instead of a neodymium and a steel. Remember that when attracting two neodymiums, the impact force is huge. The repulsion force is slightly lower than the attraction, but still large.
*The magnetic induction between like poles drops to ~0 Gs at the geometric center of the gap (due to field cancellation).
Attention: Calculations show sliding force of dual identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

A strong magnetic field poses a serious hazard to IT equipment as well as medical implants. These neodymiums generate a field that prevents correct functioning of digital equipment. Remember: the invisible magnetic field penetrates the body and plastic. Exceptional care must be exercised by people with hearing aids and insulin pumps. The risk also applies to: mechanical watches, car keys, membranes, and screens. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Table 8: Impact energy (kinetic energy) - collision effects

100 mm	82.68 km/h (22.97 m/s)	0.80 J

NdFeB products are very brittle – a violent impact against metal causes immediate chipping. Pay attention to connection velocity – a magnet released freely turns into a projectile. Impact energy can trigger coating fragments or dangerous crushing to fingers. Hold the magnet firmly during installation so it doesn't slam with momentum against the metal. A collision at high speed almost guarantees destruction of the magnet. Wear safety glasses when handling with large magnets.

Warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

The magnetic field penetrates through water without any losses. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Sliding resistance

*Note: On a vertical wall, the magnet holds just ~20% of its nominal pull.

2. Plate thickness effect

*Thin steel (e.g. computer case) significantly limits the holding force.

3. Temperature resistance

*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) = 0.89

This simulation demonstrates the magnetic stability of the selected magnet under specific geometric conditions. 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, produced from modern NdFeB material, which, at dimensions of Ø8x8 mm, guarantees optimal power. The MW 8x8 / N38 model is characterized by high dimensional repeatability and industrial build quality, making it an excellent solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 2.03 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring quick order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is perfect for building electric motors, advanced sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the high power of 19.92 N with a weight of only 3.02 g, this rod is indispensable in miniature devices and wherever every gram matters.

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 professional component. To ensure stability in industry, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Grade N38 is the most frequently chosen standard for industrial neodymium magnets, offering an optimal price-to-power ratio and high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø8x8), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 8 mm and height 8 mm. The key parameter here is the holding force amounting to approximately 2.03 kg (force ~19.92 N), which, with such defined dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which secures it against oxidation, 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 8 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.

Strengths as well as weaknesses of rare earth magnets.

Benefits

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

They have unchanged lifting capacity, and over around 10 years their performance decreases symbolically – ~1% (in testing),
Neodymium magnets are distinguished by remarkably resistant to loss of magnetic properties caused by external magnetic fields,
Thanks to the shiny finish, the layer of Ni-Cu-Ni, gold-plated, or silver gives an elegant appearance,
Magnetic induction on the working layer of the magnet remains extremely intense,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
Possibility of individual shaping and adjusting to precise conditions,
Versatile presence in advanced technology sectors – they serve a role in hard drives, drive modules, precision medical tools, also modern systems.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Limitations

What to avoid - cons of neodymium magnets: application proposals

To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously improves 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
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
Limited ability of producing nuts in the magnet and complex forms - preferred is casing - magnetic holder.
Potential hazard resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child safety. Additionally, small components of these magnets are able to disrupt the diagnostic process medical when they are in the body.
Due to expensive raw materials, their price is higher than average,

Pull force analysis

Best holding force of the magnet in ideal parameters – what affects it?

The declared magnet strength refers to the limit force, obtained under optimal environment, namely:

with the contact of a sheet made of special test steel, guaranteeing maximum field concentration
whose thickness is min. 10 mm
with a plane perfectly flat
with zero gap (without coatings)
for force acting at a right angle (pull-off, not shear)
in neutral thermal conditions

Practical aspects of lifting capacity – factors

Holding efficiency impacted by working environment parameters, including (from most important):

Distance (betwixt the magnet and the plate), since even a microscopic clearance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to paint, corrosion or dirt).
Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet holds much less (typically approx. 20-30% of nominal force).
Plate thickness – too thin plate does not close the flux, causing part of the power to be wasted to the other side.
Metal type – different alloys reacts the same. High carbon content weaken the interaction with the magnet.
Base smoothness – the smoother and more polished the surface, the better the adhesion and stronger the hold. Unevenness creates an air distance.
Temperature influence – hot environment reduces pulling force. Too high temperature can permanently damage the magnet.

Lifting capacity was assessed using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a minimal clearance between the magnet and the plate reduces the load capacity.

Warnings

Danger to the youngest

Strictly keep magnets out of reach of children. Risk of swallowing is high, and the effects of magnets clamping inside the body are very dangerous.

Health Danger

Life threat: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.

Impact on smartphones

GPS units and mobile phones are highly susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can decalibrate the internal compass in your phone.

Do not overheat magnets

Control the heat. Exposing the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and pulling force.

Bone fractures

Danger of trauma: The pulling power is so immense that it can result in blood blisters, crushing, and broken bones. Use thick gloves.

Conscious usage

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

Protect data

Powerful magnetic fields can destroy records on credit cards, HDDs, and other magnetic media. Maintain a gap of min. 10 cm.

Protective goggles

Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.

Dust is flammable

Combustion risk: Neodymium dust is highly flammable. Do not process magnets in home conditions as this may cause fire.

Skin irritation risks

Nickel alert: The Ni-Cu-Ni coating consists of nickel. If skin irritation appears, immediately stop working with magnets and wear gloves.
