Magnetic force drops sharply with every subsequent millimeter of distance. Note that every additional insulation layer (e.g., contamination, varnish, dust) noticeably weakens the grip. Magnetic products hold strongest during direct contact; distance kills the force. Notice how quickly the pull force drop, when the magnet does not touch flatly to the steel surface. When planning the assembly, eliminate unnecessary gaps.

The following data defines the approximate weight limit necessary to cause the sliding of the magnet downwards along a vertical metal surface (assuming typical friction coefficient). The holding force is a function of the air gap between the magnet and the metal.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MW 8x15 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.44 kg / 0.97 LBS 441.0 g / 4.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.29 kg / 0.65 LBS 294.0 g / 2.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.15 kg / 0.32 LBS 147.0 g / 1.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.74 kg / 1.62 LBS 735.0 g / 7.2 N

When placing a magnet on a upright plane (e.g., a car body), it will only hold only about 20%-30% of its maximum pull force. Gravity as well as a low friction coefficient cause that products slip easier than they pull off. Planning a vertical fastening? Note that the shear force is noticeably lower than the perpendicular breakaway force. On a smooth steel, the element will slip down under a significantly smaller weight. Utilizing a rubberized coating can significantly increase the grip.

12 mm	100%	1.47 kg / 3.24 LBS 1470.0 g / 14.4 N

A thin sheet is unable to absorb the entire magnetic field, which squanders power of the holder. If you attach a powerful product to a too thin substrate, the field will penetrate right through and the pull force will drop sharply. To squeeze 100% of this neodymium's power, you require a sufficiently solid backing of metal. The material oversaturation causes that on thin elements (e.g., thin profiles), the product holds weaker. We recommend selecting the steel dimension based on the following data.

Standard neodymium magnets irreversibly lose power above the temperature limit. Protect against heat – high temperature can permanently destroy this product. As the temperature rises, the magnet's power temporarily lowers. Do not use this magnet in hot environments exceeding its working range. Exceeding the critical threshold will lead to irreversible degradation of magnetism.

*Important note: Thermal stability depends not only on the material grade, but also on the magnet's shape. Flat magnets (pancake types) are more susceptible to demagnetization at lower temperatures compared to rod magnets. Warning indicator in the table signals a risk of irreversible loss for this particular item.

Two magnets interact from a wider radius than a magnet and sheet combination. The setup of two magnets produces a massive flux and a wider radius of action. Designing a solid fastener? Apply two magnets instead of one magnet and a striker plate. Be careful that when connecting a pair of magnets, the impact force is massive. 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 (resulting from vector opposition).
Important: Estimates demonstrate friction force of dual matching magnets (friction ~0.15 for Ni-Ni layer).

Extremely neodym field poses a real danger to electronics and medical implants. These NdFeB products produce a flux that disrupts operation of sensitive medical devices. Remember: the unseen radiation passes through tissues and glass. Increased vigilance must be exercised by people with hearing aids and drug dispensers. Influence will be felt by: mechanical watches, remotes, speakers, and screens. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Magnetic elements are delicate – a violent impact against metal causes immediate chipping. Watch the impact speed – a magnet released freely becomes dangerous. Kinetic force can trigger coating fragments or injury to skin. Hold the magnet firmly during bringing near metal so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Use safety goggles when playing with large magnets.

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

In water, the magnet feels stronger thanks to Archimedes' principle. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Shear force

*Note: On a vertical wall, the magnet retains just a fraction of its nominal pull.

2. Plate thickness effect

*Thin steel (e.g. 0.5mm PC case) significantly reduces the holding force.

3. Power loss vs temp

*For N38 material, 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) = 1.19

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.

This product is an exceptionally strong cylinder magnet, produced from advanced NdFeB material, which, with dimensions of Ø8x15 mm, guarantees optimal power. The MW 8x15 / N38 model boasts high dimensional repeatability and industrial build quality, making it an excellent solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 1.47 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Additionally, 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 modeling, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 14.45 N with a weight of only 5.65 g, this cylindrical magnet 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 chipping the coating of this professional component. To ensure stability in industry, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most frequently chosen standard for industrial neodymium magnets, offering a great economic balance and high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø8x15), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 8 mm and height 15 mm. The key parameter here is the holding force amounting to approximately 1.47 kg (force ~14.45 N), which, with such defined dimensions, proves the high grade of the NdFeB material. 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 8 mm. Such an arrangement is most desirable 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.

Advantages and disadvantages of Nd₂Fe₁₄B magnets.

Benefits

Apart from their notable magnetism, neodymium magnets have these key benefits:

Their magnetic field is maintained, and after around 10 years it drops only by ~1% (theoretically),
They retain their magnetic properties even under strong external field,
In other words, due to the metallic surface of nickel, the element becomes visually attractive,
Magnets exhibit excellent magnetic induction on the active area,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
Possibility of individual forming and adapting to complex needs,
Versatile presence in innovative solutions – they are utilized in hard drives, brushless drives, advanced medical instruments, also modern systems.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Cons

Disadvantages of neodymium magnets:

Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a strong case, which not only protects them against impacts but also raises their durability
Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability 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 immune to moisture, when using outdoors
We recommend a housing - magnetic holder, due to difficulties in creating nuts inside the magnet and complicated forms.
Health risk resulting from small fragments of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices are able to be problematic in diagnostics medical after entering the body.
With mass production the cost of neodymium magnets can be a barrier,

Lifting parameters

Magnetic strength at its maximum – what it depends on?

The force parameter is a measurement result performed under standard conditions:

with the use of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
with a cross-section no less than 10 mm
characterized by even structure
without the slightest air gap between the magnet and steel
during detachment in a direction perpendicular to the mounting surface
in temp. approx. 20°C

Key elements affecting lifting force

It is worth knowing that the application force will differ subject to elements below, starting with the most relevant:

Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
Material type – ideal substrate is high-permeability steel. Hardened steels may generate lower lifting capacity.
Plate texture – ground elements ensure maximum contact, which increases field saturation. Uneven metal reduce efficiency.
Thermal environment – temperature increase results in weakening of force. It is worth remembering the thermal limit for a given model.

Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the load capacity is reduced by as much as 5 times. In addition, even a minimal clearance between the magnet and the plate reduces the lifting capacity.

Warnings

Do not drill into magnets

Powder produced during machining of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.

Danger to pacemakers

Warning for patients: Strong magnetic fields disrupt electronics. Maintain at least 30 cm distance or ask another person to work with the magnets.

Thermal limits

Standard neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. The loss of strength is permanent.

Magnetic interference

A powerful magnetic field interferes with the operation of magnetometers in smartphones and navigation systems. Maintain magnets close to a device to prevent breaking the sensors.

Handling rules

Handle with care. Neodymium magnets act from a distance and connect with huge force, often faster than you can move away.

Data carriers

Avoid bringing magnets near a purse, laptop, or screen. The magnetic field can irreversibly ruin these devices and erase data from cards.

Keep away from children

NdFeB magnets are not intended for children. Swallowing several magnets can lead to them pinching intestinal walls, which poses a severe health hazard and requires immediate surgery.

Avoid contact if allergic

Nickel alert: The Ni-Cu-Ni coating consists of nickel. If skin irritation appears, immediately stop handling magnets and use protective gear.

Protective goggles

NdFeB magnets are sintered ceramics, meaning they are very brittle. Collision of two magnets will cause them cracking into shards.

Crushing force

Danger of trauma: The pulling power is so immense that it can cause hematomas, crushing, and broken bones. Use thick gloves.

Attention! More info about hazards in the article: Magnet Safety Guide.
