Magnetic force decreases drastically per each millimeter of distance. Keep in mind that every additional insulation layer (e.g., contamination, varnish, veneer) strongly reduces the pull force. Neodymiums work most effectively at the point of direct contact; gap weakens the power. See how flashily the pull force fall, when the product does not adhere tightly to the metal substrate. When calculating the arrangement, eliminate additional spacers.

The table below defines the theoretical weight limit needed to start the sliding of the magnet vertically against a vertical steel plate (assuming typical friction coefficient). The holding force is relative to the separation distance between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull
MW 10x8 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.01 kg / 2.24 LBS 1014.0 g / 9.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.68 kg / 1.49 LBS 676.0 g / 6.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.34 kg / 0.75 LBS 338.0 g / 3.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.69 kg / 3.73 LBS 1690.0 g / 16.6 N

When placing a magnet on a upright plane (e.g., a board), it will maintain just approx. 20%-30% of nominal attraction strength. Gravitational force and a low friction coefficient influence the fact that products slide down faster than they pull off. Want to create a vertical fastening? Consider that the sliding force is noticeably lower than the maximum static pull force. On a painted metal, the holder will slip down under a noticeably lighter weight. Utilizing a rubberized layer can significantly raise the stability.

A thin metal plate is not enough to conduct the full magnetic flux, which weakens actual performance of the holder. Should you attach a powerful product to a thin surface, the magnetism will pass right through and the attraction force will be weaker. To squeeze 100% of this magnet's power, you require a sufficiently solid element of steel. The material oversaturation causes that on delicate walls (e.g., car bodies), the magnet holds weaker. We suggest choosing the steel cross-section based on the following data.

Classic neodymiums lose power past the thermal threshold. Protect against heat – heat can permanently destroy this product. With every degree above norm, the neodymium's force momentarily decreases. Do not use this magnet near heat sources higher than its working range. Ignoring the limit will lead to permanent loss of magnetic properties.

*Important note: Heat tolerance is determined by both grade, as well as the dimension ratios. Low-profile magnets (low permeance coefficient) may lose charge permanently under lower heat stress than taller cylinders. Warning indicator in the table signals permanent field degradation for this particular item.

Two magnetic products interact from a significantly greater distance than a magnet and sheet combination. The setup of two magnets generates a stronger field and a wider radius of operation. Want to build a strong closure? Utilize two neodymiums instead of one magnet and a steel. Exercise caution that when attracting two neodymiums, the pinch force is huge. The repulsion force is slightly lower than the connection force, but still significant.
*Flux density in repulsion mode reaches ~0 Gs at the geometric center of the gap (caused by magnetic field nullification).
Important: Figures show friction force of dual matching magnets (friction coefficient ~0.15 for Ni-Ni layer).

A strong magnetic field is a large risk to electronic devices as well as medical implants. These NdFeB products generate a flux that prevents correct functioning of sensitive medical devices. Be aware: the invisible magnetic field penetrates the body and plastic. Increased vigilance must be taken by people with cochlear implants and drug dispensers. Also at risk are: automatic timepieces, car keys, membranes, and displays. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

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

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	27.13 km/h (7.54 m/s)	0.13 J
30 mm	46.80 km/h (13.00 m/s)	0.40 J
50 mm	60.41 km/h (16.78 m/s)	0.66 J
100 mm	85.43 km/h (23.73 m/s)	1.33 J

NdFeB products are prone to chipping – a collision with steel causes immediate chipping. Control the attraction moment – a neodymium left loose speeds with massive force. Striking energy can destroy the magnet or injury to skin. Always hold the magnet during bringing near metal so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h means shattering of the neodymium. Use safety goggles when playing with powerful specimens.

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

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 wall, the magnet retains only approx. 20-30% of its nominal pull.

2. Efficiency vs thickness

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

3. Power loss vs temp

*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) = 0.79

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 cylinder magnet, produced from durable NdFeB material, which, with dimensions of Ø10x8 mm, guarantees maximum efficiency. This specific item boasts high dimensional repeatability and industrial build quality, making it a perfect solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 3.38 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring rapid order fulfillment. Moreover, its Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

It successfully proves itself in DIY projects, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 33.16 N with a weight of only 4.71 g, this rod is indispensable in electronics and wherever every gram matters.

Since our magnets have a tolerance of ±0.1mm, the best method is to glue them into holes with a slightly larger diameter (e.g., 10.1 mm) using epoxy glues. To ensure stability in automation, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Magnets NdFeB grade N38 are suitable for 90% 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 (Ø10x8), 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 10 mm and height 8 mm. The key parameter here is the holding force amounting to approximately 3.38 kg (force ~33.16 N), which, with such compact dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface 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 10 mm. 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.

Advantages and disadvantages of neodymium magnets.

Advantages

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

They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (in laboratory conditions),
Magnets perfectly defend themselves against loss of magnetization caused by external fields,
A magnet with a shiny gold surface has an effective appearance,
Neodymium magnets generate maximum magnetic induction on a contact point, which ensures high operational effectiveness,
Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures approaching 230°C and above...
Considering the possibility of precise shaping and adaptation to unique requirements, magnetic components can be produced in a variety of shapes and sizes, which increases their versatility,
Wide application in future technologies – they are commonly used in magnetic memories, motor assemblies, advanced medical instruments, and industrial machines.
Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Cons

Drawbacks and weaknesses of neodymium magnets and proposals for their use:

To avoid cracks under impact, we suggest using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability 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 stable to moisture, in case of application outdoors
We recommend cover - magnetic mechanism, due to difficulties in producing threads inside the magnet and complicated forms.
Potential hazard related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the context of child safety. Additionally, tiny parts of these magnets can disrupt the diagnostic process medical after entering the body.
With large orders the cost of neodymium magnets is a challenge,

Holding force characteristics

Maximum lifting capacity of the magnet – what affects it?

Information about lifting capacity was defined for optimal configuration, including:

with the application of a yoke made of special test steel, guaranteeing maximum field concentration
possessing a massiveness of minimum 10 mm to ensure full flux closure
with a plane free of scratches
without any air gap between the magnet and steel
for force acting at a right angle (pull-off, not shear)
in stable room temperature

Impact of factors on magnetic holding capacity in practice

In practice, the actual lifting capacity is determined by a number of factors, listed from crucial:

Distance – the presence of any layer (paint, tape, gap) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
Metal type – not every steel attracts identically. Alloy additives worsen the attraction effect.
Base smoothness – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).

Lifting capacity testing was carried out on a smooth plate of optimal thickness, under a perpendicular pulling force, in contrast under shearing force the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate decreases the holding force.

Safety rules for work with neodymium magnets

Phone sensors

An intense magnetic field interferes with the operation of magnetometers in smartphones and navigation systems. Maintain magnets close to a smartphone to prevent damaging the sensors.

Allergic reactions

Allergy Notice: The nickel-copper-nickel coating consists of nickel. If skin irritation occurs, cease working with magnets and use protective gear.

Respect the power

Use magnets with awareness. Their huge power can shock even experienced users. Plan your moves and do not underestimate their force.

Machining danger

Mechanical processing of NdFeB material carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.

Eye protection

NdFeB magnets are sintered ceramics, which means they are fragile like glass. Clashing of two magnets leads to them breaking into shards.

Product not for children

Absolutely store magnets away from children. Risk of swallowing is high, and the consequences of magnets clamping inside the body are tragic.

Medical implants

Warning for patients: Strong magnetic fields affect medical devices. Maintain at least 30 cm distance or request help to work with the magnets.

Hand protection

Pinching hazard: The attraction force is so great that it can result in blood blisters, crushing, and broken bones. Use thick gloves.

Threat to electronics

Powerful magnetic fields can erase data on payment cards, hard drives, and storage devices. Stay away of min. 10 cm.

Heat sensitivity

Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.
